Quantum Computing Startup Funding 2025-2026

What are all the funding deals in the quantum computing market from July 2025 to June 2026?

The table below lists every disclosed equity round raised by pure-play quantum computing companies between July 2025 and June 2026. We count as “pure-play” quantum computing companies those whose core activity is quantum hardware systems, quantum computing components sold as part of systems, quantum compute access, or quantum-specific software and services used to program, run, and integrate workloads on quantum processors.

Each row shows the company, what it does, its category, the deal date, the funding stage, the round size, the region, the main investors, and the announcement source. For a wider view of how quantum computing fits inside the broader deep-tech opportunity, we cover it in our Quantum Computing market report.

How active has fundraising been in the quantum computing market?

As of June 2026, fundraising in the quantum computing market has been active on dollars and consistent enough on deal count, but it is still very lumpy. Over the past 12 months, companies raised 28 disclosed equity rounds and $6.10B combined, which works out to 2.33 deals per month.

The quantum computing market is not short of visible funding events. The 28 deals were spread across 24 unique companies, which means the dataset captures both repeat platform financings and new technical options.

The dollar flow is much less smooth than the deal flow. Average capital raised per month was $508.0M, but the median month was only $192.5M, which shows that a few financing months carried the market.

Removing the biggest rounds changes the picture completely. Excluding rounds above $50M leaves only $243.57M, meaning ordinary rounds are a small fraction of the quantum computing market’s headline funding total.

How concentrated has fundraising been in the quantum computing market?

As of June 2026, fundraising in the quantum computing market is extremely concentrated. Over the past 12 months, the largest deal alone accounts for 27.56% of total disclosed capital, the top 3 deals reach 56.27%, and the top 5 reach 71.86%.

The largest single event was Quantinuum’s $1.68B IPO raise in June 2026. That one deal is larger than all disclosed European quantum computing funding in the dataset.

The top 10 deals account for 86.44% of disclosed capital. That means the quantum computing market’s funding story is less about broad capital availability and more about a small number of platform-scale balance-sheet events.

This concentration also shows up by category. Quantum Hardware Systems represents 95.08% of capital, so the market is pricing quantum computing mainly as an infrastructure buildout problem.

How much of the quantum computing funding signal is driven by outliers?

As of June 2026, most of the funding signal in the quantum computing market is driven by outliers. Over the past 12 months, 17 of 28 disclosed deals were $50M or larger, and those megarounds dominate the capital totals.

The simplest test is to remove rounds above $50M. Total funding then falls from $6.10B to $243.57M, which means roughly 96% of disclosed capital sits in megarounds.

Rounds above $100M are also common. The dataset includes 12 deals above that threshold, or 42.86% of all disclosed deals, which is unusually high for a market still tied to deep technical uncertainty.

This means the average round size of $217.7M should not be read as typical. The median round size of $71.5M is more useful, but even that median reflects a market where large system-build rounds are normal.

Is the quantum computing market broad with many targets, or narrow with few fundable companies?

As of June 2026, the quantum computing market is broader than a one-company story but still narrow in where capital concentrates. Over the past 12 months, 24 unique companies raised 28 qualifying disclosed equity rounds.

That company count shows real formation across hardware, components, middleware, and programming software. But the capital totals show that most companies are not receiving platform-scale checks.

Only a small number of companies raised more than once in the dataset. Quantinuum, SpinQ Technology, Quantum Art, and Sygaldry Technologies each appear twice, which confirms that repeat fundraisers matter but do not fully explain the market.

The narrowness is strongest at the category level. Quantum Hardware Systems has 19 deals and $5.80B raised, while every non-hardware category combined has only $300.07M.

Is quantum computing mostly an early-stage formation market or a late-stage scaling market?

As of June 2026, the quantum computing market behaves much more like a late-stage scaling market by dollars, even though early-stage rounds are visible by count. Over the past 12 months, Seed and Series A account for 14 of 28 deals but only 9.98% of disclosed capital.

Seed activity is present but economically small. The dataset includes 5 Seed deals totaling $68.07M, which is only 1.12% of all capital raised in the quantum computing market.

Series A is the most common stage with 9 deals, but it contributes only $540.5M, or 8.87% of capital. That suggests many companies are moving from technical proof points toward first commercial systems, but the largest checks are reserved for more mature platforms.

Late-stage and growth financings dominate the capital base. Series B and later, Growth Equity, and Unknown-stage disclosed rounds together represent $5.49B, or 90.02% of capital raised.

If you want to understand which maturity levels matter most today, we cover this in more detail in our full market report on quantum computing funding.

Which categories attract the most investor attention in quantum computing?

As of June 2026, Quantum Hardware Systems attract the most investor attention in the quantum computing market by a wide margin. Over the past 12 months, the category captured 19 of 28 deals and $5.80B in disclosed capital.

That means hardware systems account for 67.86% of deals and 95.08% of capital. The gap matters because it shows investors are not just backing more hardware companies; they are writing much larger checks to them.

Quantum Computing Components came second by deal count, with 4 deals and $49.07M raised. These rounds target bottlenecks like cryogenic wiring, superconducting chips, and spin-qubit processors, but they do not yet command large market-level dollar totals.

Quantum Middleware Tools and Quantum Programming Software are strategically important but underweight in capital. Together they account for 5 deals and $251M, which is only 4.12% of the disclosed total.

Which categories attract disproportionately large checks in the quantum computing market?

As of June 2026, Quantum Hardware Systems attract disproportionately large checks in the quantum computing market. Over the past 12 months, the category has a capital share of 95.08% against a deal share of 67.86%, giving it a capital share to deal share ratio of 1.40.

The average hardware systems deal is $305.0M, and the median is $134.0M. Those numbers are far above components, middleware, and software, which confirms that investors are paying for full-stack system ambition.

Quantum Programming Software has a higher average than middleware or components because it includes Horizon Quantum’s $120M growth raise. Still, software represents only 2.53% of total capital in the quantum computing market.

Components have the weakest capital share to deal share ratio at 0.06. That does not mean components are unimportant; it means investors still expect most value capture to sit with full-stack system companies rather than suppliers.

Which geographies matter most for fundraising in the quantum computing market?

As of June 2026, North America matters most by dollars, while Europe matters most by deal count in the quantum computing market. Over the past 12 months, North America raised $4.31B from 8 deals, while Europe produced 11 deals and $1.16B.

North America captures 70.71% of disclosed capital from only 28.57% of deals. Its average deal size is $538.75M, and its median deal size is $365M, which shows how heavily the region is weighted toward platform-scale companies.

Europe captures 39.29% of deal count but only 19.01% of capital. That suggests Europe has broad quantum company formation, but it has fewer billion-dollar-scale financing events than North America.

Asia-Pacific is meaningful but smaller, with 5 deals and $435M raised. The region’s median deal size of $83M shows real industrial-scale activity, especially across China and India.

Is the quantum computing opportunity set broad or concentrated in one hub?

As of June 2026, the quantum computing opportunity set is concentrated in a few regions, but not in one single hub. Over the past 12 months, North America, Europe, Asia-Pacific, and the Middle East all produced qualifying deals.

The distribution is uneven. North America captures 70.71% of capital, Europe captures 19.01%, Asia-Pacific captures 7.14%, and the Middle East captures 3.15%.

Europe leads by activity, with 11 of 28 deals. That makes Europe the broadest formation region in the dataset, even though North America controls most of the dollars.

Latin America and Africa are absent from the qualifying dataset. That absence reflects how dependent the quantum computing market remains on specialized talent, fabrication access, cryogenic infrastructure, and strategic or sovereign buyer ecosystems.

Is quantum computing a market of small experiments or scaled financings?

As of June 2026, quantum computing is a market of scaled financings, not small experiments. Over the past 12 months, 17 of 28 disclosed deals were $50M or larger, and 12 deals were above $100M.

The lower end of the market is thin. Only 1 deal was below $5M, 4 deals were between $5M and $20M, and 6 deals were between $20M and $50M.

The median round size was $71.5M. That median is already large for a technically complex market, but it is still much lower than the average round size of $217.7M because of the largest financings.

The right way to read the quantum computing market is as a barbell. Investors are funding a few early technical options, but most capital goes to companies with system-level roadmaps and the ability to absorb very large checks.

Who are the investors that appear the most in quantum computing fundraising?

As of June 2026, only a small group of investors appear more than once in disclosed quantum computing fundraising. Over the past 12 months, the most visible repeat names are the EIC Fund, Bedford Ridge Capital, and NVIDIA or NVentures.

The EIC Fund appeared in QuiX Quantum, Equal1, and Groove Quantum. That pattern is notable because it spans photonic hardware, silicon quantum computers, and spin-qubit processor hardware.

Bedford Ridge Capital appeared in Quantum Art’s December 2025 Series A and its April 2026 Series A extension. That is a repeat-company signal rather than a broad market-coverage signal.

NVIDIA or NVentures appeared in PsiQuantum and Quantinuum, and also joined QuEra’s September 2025 expansion, although QuEra is excluded from the dataset because the incremental amount was not disclosed and the base round was announced before July 2025.

One caveat matters: public announcements usually disclose round size, not individual investor check size. So repeat investor visibility should be read as participation evidence, not as a precise ranking of dollars committed.
