What are the fundraising trends in the AI infrastructure market?
In our AI infrastructure market deck, you will find everything you need to understand the market
SUMMARY
We analyzed publicly disclosed equity rounds raised by pure-play AI infrastructure companies across full-year 2024, full-year 2025, and January through May 2026. The dataset keeps disclosed rounds of $300K or more, excludes debt, grants, IPOs, acquisitions, and non-pure-play AI application companies, and covers AI Accelerators, AI Server Systems, AI Cluster Cloud, AI Network Fabric, AI Storage Systems, and AI Compute Platforms.
The AI infrastructure market is accelerating sharply. Funding rose from about $4.8B in 2024 to about $8.6B in 2025, then reached about $6.4B in the first four months of 2026 alone.
The current surge is real, but it is not evenly distributed. In year-to-date 2026, the top three deals captured about 70% of all capital, and the top 10 captured nearly 98%.
Round sizes in the AI infrastructure market have moved into infrastructure territory. The median round rose from about $91M in 2024 to about $200M in 2025 and about $228M in year-to-date 2026.
AI Cluster Cloud is the capital magnet. It captured about $4.0B in year-to-date 2026, or nearly 63% of all funding, from only three deals.
AI Accelerators remain active by deal count, with four of the 14 year-to-date 2026 deals, but they no longer dominate dollars. Investors are still funding chip alternatives, but the largest checks are flowing to deployable compute capacity and integrated systems.
The market is moving later-stage by capital. Seed and Series A rounds represented about 43% of year-to-date 2026 deals but only about 8% of capital, while Series B and later captured more than 92% of dollars.
First financings have disappeared from the visible 2026 dataset. Every qualifying year-to-date 2026 round was a follow-on financing, which means public capital is mostly recapitalizing companies that already cleared a credibility threshold.
North America remains the deepest region, but Europe is gaining capital share. Europe captured about 35% of year-to-date 2026 capital, mostly because of Nscale's $2B Series C and reinforced by Kandou AI and Optalysys.
Strategic investors are central to the AI infrastructure market. NVIDIA, Intel, Arm, Dell, Nokia, Synopsys, Cadence, Alchip, Marvell, Samsung, SK Hynix, and other industrial players appear across the dataset, making the funding environment partly a supply-chain and ecosystem-control contest.

Is more or less capital going into the AI infrastructure market?
More capital is going into the AI infrastructure market, and the increase is large enough to treat as a real acceleration rather than background noise. Year-to-date 2026 funding reached about $6.4B across 14 deals, compared with about $1.1B across 4 deals over the same calendar window in 2025.
The full-year comparison points in the same direction. The AI infrastructure market moved from about $4.8B in 2024 to about $8.6B in 2025, even though deal count fell from 28 to 22. That means the market was not just busier; it became much more capital-intensive.
The freshest signal is even stronger. By May 2026, the AI infrastructure market had already raised roughly three-quarters of the entire 2025 full-year total. That is a meaningful pace for a market measured only through the first part of the year.
The honest interpretation is that more capital is going in, but not democratically. CoreWeave and Nscale each raised $2B in early 2026, and the top three 2026 deals accounted for about 70% of total capital. So the market is expanding mainly through companies that can plausibly absorb infrastructure-scale checks.
For deeper context on how capital is shifting across AI cloud, compute platforms, chips, interconnect, and systems, see the full AI infrastructure market report.
Is AI infrastructure funding driven by more deals or larger rounds?
AI infrastructure funding is being driven more by larger rounds than by a broad-based increase in deal count. The cleanest proof is 2025: total funding rose sharply from 2024, while deal count fell from 28 to 22.
The average round size makes the point obvious. In 2024, the average AI infrastructure round was about $172M and the median was about $91M. In 2025, the average jumped to about $390M and the median rose to about $200M.
Year-to-date 2026 adds a second layer. Deal count rebounded versus the weak early-2025 comparison, with 14 deals versus 4, but the average round was still about $458M and the median was about $228M. That is not a normal venture formation curve.
The deal-size distribution confirms the shift. In year-to-date 2026, 11 of 14 rounds were above $50M, and 10 of 14 were above $100M. The practical takeaway is that the AI infrastructure market is no longer funded like ordinary software; capital intensity is part of the product.
For more detail on round-size distribution, medians, and concentration effects, see the AI infrastructure market deck.
Is AI infrastructure capital moving toward later-stage or earlier-stage companies?
AI infrastructure capital is moving decisively toward later-stage companies, even though Series A rounds still appear frequently by count. The key is to weight dollars more heavily than deal count, because dollars show where investors are placing serious conviction.
In year-to-date 2026, Seed and Series A rounds represented about 43% of deals but only about 8% of capital. Series B and later rounds captured about 92% of dollars.
The same pattern appears across prior years. In 2024, early and unknown-stage rounds were half of all deals but only about 15% of capital. In 2025, Seed and Series A rounds captured just about 2% of capital.
The nuance is that a Series A round in the AI infrastructure market often does not mean a classic new-company formation event. Several 2026 Series A financings were follow-on rounds for technically mature hardware, systems, or platform companies. In this market, “early-stage” can still mean a company needs tens or hundreds of millions to prove manufacturing, deployment, or system performance.

Is the AI infrastructure market maturing or still experimental?
The AI infrastructure market is maturing financially, but it remains technically experimental inside several subcategories. The capital structure looks mature; the architecture of the next winning stack is still being contested.
The maturity signal is strongest in the stage mix. In 2025, late-stage and Series B+ financings captured nearly 98% of all capital. In year-to-date 2026, late-stage and Series B+ rounds captured about 92% of capital.
Round sizes tell the same story. The median round moved from about $91M in 2024 to about $200M in 2025 and about $228M in 2026 so far. A market with a $200M-plus median round is not being funded like a loose set of experiments.
But the technical picture is still open. AI Accelerators, AI Server Systems, AI Cluster Cloud, AI Compute Platforms, and AI Network Fabric all attracted capital in year-to-date 2026. The practical takeaway is that investors believe the winners need scale now, while the best technical answer to compute scarcity, inference efficiency, memory movement, interconnect, and power delivery remains unsettled.
Are new startups still entering the AI infrastructure market?
New startups are still entering the AI infrastructure market, but public funding evidence shows that new-company formation is no longer the main story. In year-to-date 2026, there were no first financings in the qualifying public dataset.
That does not mean no new AI infrastructure startups exist. It means very young companies are not showing up in the public equity record at meaningful disclosed sizes. They may be in stealth, below the reporting threshold, grant-funded, customer-funded, or not yet ready for institutional-scale rounds.
The trend is clear across years. In 2024, first financings represented 25% of deals and about 7% of capital. In 2025, only one first financing appeared, and it captured almost no capital. In 2026 so far, first financings disappeared from the visible dataset.
The real signal is that the bar for visibility has risen. A new AI infrastructure startup now needs more than a generic infrastructure label. It needs a credible claim on scarce compute, a differentiated chip or interconnect architecture, a strategic supply-chain partner, or ownership of a bottleneck such as inference efficiency, memory movement, networking, storage, or power delivery.
For a broader view of first financings, follow-on rounds, and the formation curve, see the market report covering AI infrastructure startup formation.
Are more investors entering the AI infrastructure market?
More high-quality investors are entering or staying active in the AI infrastructure market, but the expansion is concentrated among strategic, growth-stage, and infrastructure-literate backers rather than broad seed participation. By May 2026, the dataset already included roughly 35 tier-1 investors, which is high for only four months of activity.
The broader investor count also expanded. Year-to-date 2026 had roughly 69 disclosed investors, compared with roughly 25 to 30 over the same calendar period in 2025. Some of that increase comes from large syndicates around CoreWeave, Nscale, MatX, Baseten, SambaNova, Rebellions, and Kandou AI.
The more important signal is who appears, not just how many investors appear. NVIDIA, Intel, Arm, Dell, Nokia, Synopsys, Cadence, Alchip, Marvell, Samsung, SK Hynix, SoftBank, QIA, Aramco Ventures, and other strategic or industrial investors show up across the 2026 dataset.
That means investor participation is becoming more sophisticated, not merely more crowded. In the AI infrastructure market, a strategic investor can be more informative than a higher headline valuation because it may imply access to manufacturing, procurement, distribution, customers, or ecosystem adoption.

Are top investors getting more or less active in AI infrastructure?
Top investors are getting more active in the AI infrastructure market, but their activity is selective and stack-wide rather than evenly distributed. The strongest evidence is repeat participation by NVIDIA, Fidelity, AMD Ventures, Intel, Arm, Valor, Atreides, Altimeter, CapitalG, Spark, Maverick Silicon, and other major investors across multiple years and layers of the market.
In year-to-date 2026, NVIDIA appeared in CoreWeave, Baseten, and Nscale. Intel or Intel Capital appeared in SambaNova and EPIC Microsystems. Arm appeared in Positron AI and Rebellions. Alchip appeared in MatX and Kandou AI.
These are not just financial bets. They are positions in ecosystem control points: cloud capacity, inference systems, chip design, interconnect, manufacturing, and power delivery.
The practical takeaway is that top investors are not spraying capital blindly. They are assembling exposure around bottlenecks. The AI infrastructure market is increasingly funded by investors that understand where constraint, supply, and system-level leverage may appear next.
Which AI infrastructure subcategories are gaining momentum?
The AI infrastructure subcategories gaining momentum are AI Cluster Cloud, AI Compute Platforms, and AI Server Systems. AI Accelerators remain active by deal count, but they are no longer the capital-share leader.
AI Cluster Cloud is the clearest winner. It captured about $2.4B in 2024, about $4.6B in 2025, and about $4.0B in year-to-date 2026. By 2026, it represented nearly 63% of all capital from only about 21% of deals.
AI Compute Platforms are also gaining momentum. The category rose from only about $46M in 2024 to about $1.5B in 2025, then reached about $530M in the first part of 2026. That suggests investor attention is moving from raw compute availability toward platforms that make compute usable for inference, deployment, orchestration, and production workloads.
AI Server Systems are the newest momentum category. There were no qualifying AI Server Systems deals in 2024, one $1.1B Cerebras round in 2025, and three deals totaling about $601M in year-to-date 2026. That points to a real shift toward integrated systems, inference appliances, rack-scale architectures, power delivery, and alternatives to generic GPU clusters.
We cover this subcategory shift in the deeper analysis of the AI infrastructure market, including the split between cloud, chips, systems, interconnect, storage, and compute platforms.
Which AI infrastructure subcategories are losing momentum?
The AI infrastructure subcategories losing visible momentum are AI Storage Systems, AI Network Fabric by deal count, and AI Accelerators by relative capital share. This does not mean those technologies are unimportant. It means public equity funding is concentrating elsewhere.
AI Storage Systems have the clearest loss of visible momentum. Storage had one qualifying deal in 2024, three in 2025, and zero in year-to-date 2026. The honest interpretation is not that storage stopped mattering, but that storage may be getting bundled into broader cloud, data-center, and platform financings rather than funded as a standalone pure-play category.
AI Network Fabric is more complicated. The category raised about $752M in 2024, about $415M in 2025, and about $225M in year-to-date 2026. The 2026 Kandou AI round was large enough to show strategic validation, but one deal does not make a broad wave.
AI Accelerators are losing momentum only when measured by capital share. They captured about 31% of capital in 2024, less than 10% in 2025, and about 16% in 2026 so far. Investors still want exposure to chip alternatives, but they are applying a commercialization discount relative to deployable cloud capacity and integrated systems.

Which regions are gaining momentum in AI infrastructure funding?
Europe is gaining the most momentum by capital share in the AI infrastructure market, while North America remains the dominant region by both dollars and deal count. The freshest comparison is decisive: Europe captured about $2.25B in year-to-date 2026, compared with no European capital over the same calendar period in 2025.
The full-year pattern points in the same direction. Europe captured about $275M in 2024, about $1.1B in 2025, and about $2.25B in year-to-date 2026. That is a clear upward sequence.
The caveat is concentration. Europe’s 2026 capital share came from only three deals: Nscale, Kandou AI, and Optalysys. The region is gaining momentum through a few strategically important infrastructure companies, not through a wide base of funded startups.
Asia-Pacific is gaining some momentum by deal presence and capital, but remains smaller. It captured about $174M in 2024, $375M in 2025, and $422M in year-to-date 2026, with 2026 activity coming from Rebellions and Nava. That points to credible regional AI infrastructure activity, especially around chips and sovereign or regional cloud infrastructure.
For ongoing regional tracking across North America, Europe, Asia-Pacific, and other regions, see the full market view on AI infrastructure regions.
Which regions are losing momentum in AI infrastructure funding?
The Middle East is losing visible momentum in the AI infrastructure market as a company-headquarters region, while North America is losing share but not absolute relevance. The Middle East had one qualifying 2024 deal, Hailo's $120M round, but no qualifying company-region deals in 2025 or 2026 so far.
North America’s story is more nuanced. In absolute dollars, North America is not losing momentum: it raised about $4.3B in 2024, about $7.1B in 2025, and about $3.7B in year-to-date 2026. But as a share of global AI infrastructure capital, it declined from about 88% in 2024 to about 83% in 2025 and about 58% in 2026 so far.
That share decline should not be read as North American weakness. It should be read as Europe finally producing mega-scale rounds, especially Nscale.
Latin America and Africa had no qualifying public equity activity across the measured periods. They are not so much losing momentum as remaining outside the visible public financing market for pure-play AI infrastructure.
Is AI infrastructure becoming more global or regionally concentrated?
The AI infrastructure market is becoming somewhat more global by capital distribution, but it remains concentrated in North America and a small number of European and Asia-Pacific winners. The best evidence is the shift in North America's capital share, which moved from about 88% in 2024 to about 83% in 2025 and about 58% in year-to-date 2026.
That does not mean the market is broadly global. In 2026 so far, North America, Europe, and Asia-Pacific accounted for 100% of qualifying public equity capital. Latin America, Africa, and the Middle East had no qualifying company-region capital.
Europe’s 35% share in 2026 came from only three deals, and Asia-Pacific’s 7% share came from only two. So the market is geographically wider than before, but still concentrated in a handful of regions and companies.
The correct interpretation is that AI infrastructure is becoming more global at the top, not more globally diffuse at the base. Sovereign compute, regional AI cloud capacity, semiconductor supply chains, and data-center constraints are pulling Europe and Asia-Pacific into the market, while North America remains the deepest financing center.

Is AI infrastructure capital moving toward proven winners or new opportunities?
AI infrastructure capital is moving toward proven winners far more than new opportunities. The most relevant indicators are follow-on share, first-financing share, stage mix, and capital concentration.
In year-to-date 2026, 100% of qualifying deals and 100% of capital went to follow-on financings. In 2025, only one deal was a first financing, and it captured just 0.08% of capital. That is an overwhelming signal.
The full-year comparison shows the shift clearly. In 2024, first financings represented 25% of deals and 7% of capital. That already meant capital favored follow-ons, but new opportunities were still visible. By 2025, first financings nearly vanished; by 2026 so far, they disappeared from the public disclosed equity record.
There is still room for new technical opportunities, but they are being funded as bottleneck bets rather than generic startup formation. Neurophos, Optalysys, Kandou AI, EPIC Microsystems, and Gimlet Labs show investor appetite for emerging architectures. But even those companies are follow-on financings, often with strategic backers.
The AI infrastructure market report tracks these repeat raisers and bottleneck-specific companies across cloud, compute, accelerators, server systems, storage, and network fabric.
Is the AI infrastructure market becoming winner-takes-most?
Yes, the AI infrastructure market is becoming winner-takes-most by capital allocation, but not winner-takes-all by company formation. The top three year-to-date 2026 deals captured about 70% of total capital, and the top 10 captured nearly 98%.
The 2026 concentration is especially high because CoreWeave and Nscale each raised $2B. That does not mean the whole market has only two viable companies. It means the biggest checks are going to companies that can credibly absorb billions into compute capacity, data-center expansion, and large-scale infrastructure deployment.
The bottom-half capital share confirms the pattern. In 2024, the bottom half of deals captured about 12% of capital. In 2025, the bottom half captured about 11%. In 2026 so far, it captured about 10%. Even as total capital rises, the smaller half of the market is not taking a larger share.
The market is not winner-takes-all because there are multiple bottlenecks. Cluster cloud, compute platforms, accelerators, server systems, network fabric, storage, and power delivery each have different validation paths. But it is winner-takes-most because the largest companies in each bottleneck category are pulling away financially.
Is the next wave of AI infrastructure winners becoming visible?
The next wave of AI infrastructure winners is becoming visible, but the evidence is strongest for scale-up contenders rather than brand-new startups. The likely winners are not hidden in seed rounds; they are visible in large follow-on financings, strategic investor participation, and category positions tied to compute scarcity and system bottlenecks.
The strongest candidates by capital and strategic validation include Nscale, CoreWeave, Lambda, Crusoe, Baseten, Groq, Cerebras, Rebellions, MatX, Celestial AI, Positron AI, SambaNova, and Kandou AI. These companies are not all comparable, but they all touch scarce infrastructure bottlenecks.
The caution is that visibility is not certainty. A large round validates access to capital, but it does not automatically validate durable margins, customer retention, supply-chain execution, or performance leadership.
The practical filter is conversion. The next wave of winners will be the companies that turn capital into reliable capacity, production inference economics, power efficiency, manufacturing paths, ecosystem adoption, and defensible customer demand.
For more context on the companies and bottlenecks that define the next wave, see the AI infrastructure market deck.
As this chart shows, and as featured in our AI infrastructure market deck, search interest in AI infrastructure has risen sharply
Is the AI infrastructure funding landscape fragmenting or consolidating?
The AI infrastructure funding landscape is consolidating by capital but fragmenting by technical approach. This is one of the most important tensions in the market.
The consolidation signal is unmistakable. In year-to-date 2026, the top three deals captured about 70% of capital. In 2025, the top 10 captured about 86%. In 2024, the top 10 captured about 79%. Funding power is concentrating at the top.
But the category map shows fragmentation. In 2026 so far, capital went into AI Cluster Cloud, AI Accelerators, AI Server Systems, AI Compute Platforms, and AI Network Fabric. The only absent category was AI Storage Systems.
The better interpretation is that the AI infrastructure market is financially consolidating while architecturally fragmenting. Many technical pathways can exist, but only a smaller number of companies can raise the capital required to become infrastructure-scale category leaders.
Where is investor attention shifting in AI infrastructure?
Investor attention in the AI infrastructure market is shifting from generic AI infrastructure exposure toward deployable compute capacity, inference infrastructure, integrated systems, and bottleneck-specific hardware layers. The strongest evidence is the movement of capital toward AI Cluster Cloud, AI Compute Platforms, AI Server Systems, and system-level accelerator companies.
The first shift is toward deployable capacity. AI Cluster Cloud captured about 49% of 2024 capital, 53% of 2025 capital, and 63% of 2026 year-to-date capital. Investors are paying for companies that can give customers access to scarce AI compute, not just promise better infrastructure later.
The second shift is toward inference and production AI workloads. Groq, Baseten, Fireworks AI, Together AI, Positron AI, SambaNova, MatX, Rebellions, and Gimlet Labs all point to the same broader theme: the market is moving beyond training scarcity into inference economics, deployment reliability, model serving, and workload-specific systems.
The third shift is toward system bottlenecks: power delivery, memory movement, interconnect, photonics, and chip-to-chip connectivity. EPIC Microsystems, Kandou AI, Neurophos, Optalysys, Celestial AI, Avicena, Ayar Labs, Lightmatter, and Celero show that investors are looking for the constraints that emerge after GPUs are procured.
The broader read is simple. Investor attention is moving toward companies that can occupy control points in the AI infrastructure stack, not just companies with impressive technical claims.
INSIGHTS
The insights below come from reviewing publicly disclosed equity rounds in the AI infrastructure market across full-year 2024, full-year 2025, and January through May 2026.
- The AI infrastructure market is best understood as a capital-intensity race, not a conventional venture adoption curve. Median rounds rose from about $91M in 2024 to about $200M in 2025 and about $228M in year-to-date 2026, which means the baseline cost of credibility has moved sharply upward.
- Headline growth is real, but it is not democratic. The top three deals captured about 49% of 2024 capital, 46% of 2025 capital, and 70% of year-to-date 2026 capital, so market expansion is being driven by a small number of companies capable of absorbing infrastructure-scale checks.
- Deal count alone is increasingly misleading. Full-year 2025 had fewer deals than 2024 but far more capital, so a researcher focused only on activity volume would incorrectly describe the market as slowing.
- The market is maturing financially faster than it is maturing technically. Late-stage and Series B+ rounds dominate capital, but investors are still testing multiple architectures across cloud, accelerators, server systems, interconnect, power delivery, and heterogeneous compute.
- AI Cluster Cloud is the clearest capital magnet because it turns funding into near-term deployable capacity. That gives it a different validation profile from chip and interconnect companies, which often require longer technical and manufacturing proof cycles.
- AI Accelerators remain important, but they are no longer the whole story. Their deal count is strong, yet the biggest checks now go to companies that can deliver usable systems, cloud capacity, or production inference economics.
- AI Server Systems are emerging as a distinct funding category. The move from zero qualifying 2024 deals to Cerebras in 2025 and Positron AI, SambaNova, and EPIC Microsystems in 2026 suggests investors are paying more attention to integrated systems and rack-level infrastructure.
- AI Storage Systems have weak visible momentum as a standalone category. That does not mean storage is unimportant; it may mean the storage layer is being bundled into broader cloud, data-center, and platform financings rather than funded as a pure-play market.
- Network Fabric looks selective rather than dead. One large Kandou AI round in 2026 is enough to validate the interconnect bottleneck, but too narrow to prove broad category momentum.
- First financings are the most important missing signal. The absence of first financings in year-to-date 2026 means the public AI infrastructure market is no longer mainly about company creation; it is about recapitalizing companies that already have technical or strategic validation.
- Strategic investors matter more in AI infrastructure than in ordinary software markets. NVIDIA, Intel, Arm, Dell, Nokia, Synopsys, Cadence, Alchip, Marvell, Samsung, SK Hynix, and similar names can validate supply-chain access, manufacturing paths, customer routes, or ecosystem relevance.
- The repeated presence of semiconductor and systems strategics means future rounds without strategic participation may deserve a higher diligence discount. A purely financial syndicate can still be strong, but it does not carry the same ecosystem signal in a hardware-heavy market.
- Europe is gaining momentum at the top, not across the base. Nscale, Kandou AI, and Optalysys made Europe much more visible in 2026, but three deals do not yet make the region broadly deep.
- North America remains the deepest AI infrastructure financing market even when its share falls. Its absolute capital and deal count remain high, and its company base spans cloud, platforms, accelerators, systems, storage, and interconnect.
- Capital is moving toward proven winners. A market where 100% of year-to-date 2026 capital went to follow-on rounds is not mainly betting on new formation; it is funding companies that already have credibility.
- The market is winner-takes-most because capital helps secure the very inputs needed to win. The best-funded companies can move faster on chips, power, data centers, customers, suppliers, and strategic relationships.
- Category labels can hide very different risk profiles. CoreWeave and Nscale are capacity and deployment plays, MatX and Neurophos are deep hardware bets, Gimlet and Baseten are inference or orchestration platform plays, and EPIC Microsystems and Kandou AI attack component-level bottlenecks.
- The cleanest forward-looking rule is that fundable AI infrastructure companies need to prove deployable capacity, manufacturing path, strategic ecosystem alignment, or bottleneck ownership. Companies with only generic AI tooling claims but no direct compute, cluster, chip, interconnect, power, storage, or inference-layer control should be discounted.

OUR METHODOLOGY TO BUILD THIS TRACKER
We built this AI infrastructure funding tracker by reviewing publicly disclosed equity rounds raised by pure-play AI infrastructure companies across full-year 2024, full-year 2025, and January through May 2026. A company counts as pure-play when more than 80% of its activity is dedicated to the compute, cloud, cluster, server, accelerator, network, storage, or deployment infrastructure required to run AI training or inference at scale.
We applied four filters to build the dataset. First, we only included equity rounds, so grants, debt, structured financings, IPOs, public offerings, acquisitions, SPAC transactions, and business combinations are excluded unless the raw dataset explicitly treated the disclosed equity component as qualifying. Second, we only counted rounds of $300K or more. Third, we only kept pure-play AI infrastructure companies, which means we excluded model-product companies, AI application companies, generic MLOps tools, broad cloud optimization businesses, and companies where the compute-and-cluster layer was not the core activity. Fourth, every entry had to be confirmed by a direct company announcement, press release, tier-1 media report, specialized industry source, or relevant regional publication.
Undisclosed-amount rounds are excluded because including them would distort dollar-based metrics such as average round size, median round size, category capital share, stage capital share, and concentration ratios. The final analysis uses only disclosed public equity rounds that passed the pure-play and size filters. Privately raised rounds, unannounced SAFEs, undisclosed small seed rounds, and secondary transactions that were never publicly reported are necessarily missing, which is a known limitation of any public-only AI infrastructure funding tracker.
