Published estimates show quantum investment rose sharply in 2025, but much of it went to a small number of large deals. That leaves room for a real financing squeeze among individual startups; it does not establish that the sector as a whole has too many companies, or reveal how many private firms are close to running out of cash.
What the funding numbers show—and what they do not
Two recent estimates describe a substantial increase in quantum financing, but they measure different things and should not be added together.
| Measure | Reported figure | What it represents |
|---|---|---|
| Quantum technology startup investment | $12.6 billion in 2025, 6.3 times the 2024 amount; 90% went to quantum computing startups. | McKinsey’s estimate of startup investment. Its separate analysis says roughly 60% of the 2025 total was concentrated in the ten largest deals. McKinsey, April 28, 2026. |
| New private venture capital | $4.9 billion in 2025, up 192% year over year. | QED-C’s estimate of new private VC, based on data through the end of 2025—not government commitments or company revenue. QED-C, April 14, 2026. |
| New government funding commitments | $12.7 billion in 2025, up 310% year over year. | QED-C’s estimate of commitments. A commitment is not necessarily cash already received by a startup. QED-C, April 14, 2026. |
The estimates differ in scope and methodology. They are evidence of stronger aggregate funding, not a single pot available to every company. Public commitments, private venture rounds, investment totals, and revenue are distinct measures.
Why a growing market can still leave startups short of cash
Funding is concentrated. McKinsey estimates that about three-fifths of 2025 investment went to the ten largest deals, and describes leading firms as benefiting from better access to talent and increasingly expensive hardware and infrastructure. This pattern can leave smaller or less-established companies competing for a narrower share of capital even while headline totals rise.

The European Securities and Markets Authority (ESMA) reports that EU-based quantum computing startups raised about €950 million across 25 deals in 2025. Across Europe, eight companies each raised more than €100 million, while 52 other startups collectively attracted around €1 billion. The larger rounds and the aggregate for the other firms illustrate concentration, but neither tells us how much cash any company has left or whether its financing is sufficient. ESMA, May 13, 2026.
Quantum businesses also face a long path from research and infrastructure spending to dependable commercial income. McKinsey says near- to medium-term returns on investment are difficult to quantify and that most applications remain experimental or hybrid. Strong fundraising therefore cannot be treated as proof that products are already producing enough revenue to finance continued development.
Is quantum startup funding drying up?
The available figures do not support a claim that sector-wide funding dried up in 2025: both McKinsey’s investment estimate and QED-C’s private VC and government-commitment measures rose sharply. They also do not show that financing is readily available to every startup. The largest-deal concentration, substantial infrastructure needs, and early commercial maturity mean an individual firm’s access to capital can differ sharply from the sector total.
QED-C counted 556 pure-play quantum companies at the end of 2025. That is evidence of a sizeable company landscape, not evidence that there are “too many” firms relative to available funding. The count says nothing by itself about each company’s quality, funding needs, cash runway, or prospects.
What market growth forecasts mean for survival
QED-C describes quantum computing as a $1.4 billion market in 2025 and projects it will reach $3 billion by 2028. The 2028 figure is a forecast, not realized revenue or a guarantee that sales will flow to every vendor. A growing addressable market can coexist with companies that fail to win customers, secure follow-on financing, or cover the costs of building and operating their systems.
For founders and investors, the distinction is practical: a market forecast is not a cash-flow forecast for a particular company. Survival depends on company-level factors such as available cash, committed financing, spending requirements, customer contracts, and the timing of product milestones. The sector-wide sources do not provide a reliable private-startup runway figure or count of firms at risk.

Does consolidation prove startups are running out of money?
No. McKinsey reports accelerated quantum-sector M&A activity in 2025, including multiple acquisitions by IonQ. QED-C describes acquisitions as a way to expand market access, add enabling technologies, or broaden products. Those are plausible strategic reasons for consolidation; the cited sources do not establish that a shortage of capital alone caused the deals.
ESMA also notes that listed pure-play companies remain early in commercialization and operate at significant losses. That observation concerns listed firms, not every private startup, and losses alone do not establish imminent insolvency. A company-specific claim about financial distress needs company-level evidence such as filings, audited accounts, a financing announcement, or an explicit management statement.

Where founders can look for specialist investors
ESMA identifies Quantonation, Quantum Coast Capital, and 55 North as specialist quantum investors. It reports that Quantonation closed a €220 million early-stage quantum technology fund in February 2026, and that 55 North launched a fund with a €300 million target in 2025. These facts identify participants in the financing ecosystem; they do not confirm that either fund is currently accepting applications, that a particular startup qualifies, or that funding is available on any specific terms. Founders should verify current investment focus and approach processes directly.
How to assess a particular startup’s financing risk
There is no reliable sector-wide statistic for private quantum startup runway, expected insolvencies, or the number of firms in immediate danger. To assess a named company, use evidence tied to that company rather than extrapolating from sector totals:
- Check the cash and financing evidence. Look for audited accounts, regulatory filings where applicable, and explicit statements about cash, debt, or funding raised.
- Separate announced funding from available cash. A target, commitment, or planned round is not necessarily money already received.
- Look for commercial evidence. Customer contracts and recurring revenue are more informative about operating income than a market-size forecast.
- Read transaction news carefully. An acquisition may be strategic and does not by itself prove the acquired company was insolvent.
- Keep the date and scope attached to each figure. Funding, fund availability, and company finances can change after a report is published.
QED-C’s executive director Celia Merzbacher said global public and private funding grew significantly in 2025, with governments and venture investors increasing commitments and companies hiring more workers. That sector-level momentum is compatible with uneven access to capital; it cannot answer which private startups are running out of money.
