In our quantum computing market deck, we identify pain points entrepreneurs should prioritize
How has funding activity in the quantum computing market changed over time?
Q3 2025 was the most active quarter because PsiQuantum, Quantinuum, Quantum Computing Inc., D-Wave, and IQM created several very large rounds.
Q1 2026 was the least active quarter because its six deals totaled only $100.7 million and the largest round was $60 million.
Quantum computing market funding increased by about 1,598% from Q1 2026 to Q2 2026, and by about 261% from Q2 2025 to Q2 2026.
After removing the largest one or two rounds in each quarter, the quantum computing funding trend looks less extreme. Q2 2026 still appears broad because many separate companies raised more than $50 million.
| Quarter | Number of deals | Total raised ($) | Comment |
|---|---|---|---|
| Q2 2025 | 3 | $473M | Rigetti's public equity sales represented most of the quarter, while Classiq added one large private software round. |
| Q3 2025 | 15 | $3,025M | Several mega-rounds made Q3 2025 the strongest quarter, led by PsiQuantum, Quantinuum, and Quantum Computing Inc. |
| Q4 2025 | 8 | $991M | Quantum Computing Inc.'s $750 million placement dominated a quarter that otherwise contained mostly smaller private rounds. |
| Q1 2026 | 6 | $101M | No mega-round appeared, making Q1 2026 the quietest quarter for quantum computing market funding. |
| Q2 2026 | 15 | $1,709M | Ten rounds exceeded $50 million, showing broader scaling across several quantum hardware companies and production approaches. |
| All quarters | 47 | $6,299M | Funding was large overall, but hardware companies and a limited number of mega-rounds captured most capital. |

Is the quantum computing market shifting toward smaller or bigger deals?
The average announced quantum computing deal across all five quarters was about $134 million, although mega-rounds lifted this figure sharply.
Quarterly averages ranged from about $16.8 million in Q1 2026 to $201.6 million in Q3 2025. The difference mainly reflects whether a quarter included several very large hardware financings.
Without the largest outliers, the quantum computing market shows a steadier rise in medium and large rounds rather than a simple move toward mega-deals.
| Quarter | Number of deals | Average deal size ($) | Deals below $2M | Deals above $50M |
|---|---|---|---|---|
| Q2 2025 | 3 | $157.67M | 0 | 2 |
| Q3 2025 | 15 | $201.64M | 0 | 5 |
| Q4 2025 | 8 | $123.90M | 1 | 3 |
| Q1 2026 | 6 | $16.78M | 1 | 1 |
| Q2 2026 | 15 | $113.96M | 1 | 10 |
| All quarters | 47 | $134.02M | 3 | 21 |

How concentrated was funding activity in the quantum computing market?
Quantum computing market funding was highly concentrated, especially in Q2 2025 and Q4 2025, when one deal represented about three quarters of all capital. Q2 2026 was more balanced because its largest round represented only 20.5%.
This pattern shows that quarterly totals can move sharply when one hardware company completes a major financing, even when the wider deal market changes less.
| Quarter | Number of deals | Top 1 | Top 3 | Top 10 |
|---|---|---|---|---|
| Q2 2025 | 3 | 74.00% | 100.00% | 100.00% |
| Q3 2025 | 15 | 33.06% | 69.43% | 98.46% |
| Q4 2025 | 8 | 75.67% | 91.81% | 100.00% |
| Q1 2026 | 6 | 59.58% | 85.00% | 100.00% |
| Q2 2026 | 15 | 20.48% | 42.59% | 94.23% |
| All quarters | 47 | 15.88% | 37.31% | 76.65% |
This chart, featured in our quantum computing market deck, illustrates how revenue is divided among customer segments in the quantum computing market
Which categories in the quantum computing market received the most funding?
Quantum-hardware systems captured about 90% of all funding because processors and complete machines require expensive engineering, manufacturing, and deployment programs. Investors also place more strategic value on companies that control scarce computing capacity.
Quantum-computing components raised $372.8 million across 12 deals because cooling, fabrication, control, and networking remain important bottlenecks. However, component suppliers usually require less capital than complete-system builders.
Quantum-programming software raised $201.1 million across six deals because enterprises need easier development tools and useful algorithms. Software funding remains smaller because practical quantum workloads are still limited.
