Europe’s AI funding has tripled, but mid-sized rounds have barely moved.
Europe’s AI funding almost tripled in the first nine months of 2026, while investment rounds worth 25 million euros to 100 million euros barely changed. Tech.eu’s European AI funding data shows 18 rounds worth 25 million to 100 million euros in the first nine months of 2025, compared with 17 during the same period in 2026. I checked the underlying announcements and excluded transactions that could not be compared consistently. That left 14 rounds in each year, with approximately 617 million euros raised in 2025 and 640 million euros in 2026.
This is a particularly important range for AI companies moving beyond their first customers. Expanding into new markets requires substantial capital, even for businesses operating on a completely different financial scale from Europe’s largest AI developers. The near-standstill in this segment deserves attention when overall AI funding has almost tripled.
How Europe’s AI funding splits across the market
According to Tech.eu, European AI funding reached 12.7 billion euros in the first nine months of 2026, up from 4.2 billion euros a year earlier. The number of rounds also increased, from 139 to 229. These figures follow Tech.eu’s sector definitions and include some debt financing.
I broke down Tech.eu’s recorded transactions by round size. Deals below 25 million euros increased from 99 to 173, while rounds worth 100 million euros or more jumped from seven to 18. These large investments accounted for almost 87 per cent of disclosed funding in 2026, compared with around 71 per cent the previous year. The ten biggest deals still represented roughly three quarters of the total, suggesting that the shift extends beyond a handful of mega-rounds.
In between, the 25–100 million euros segment lost ground. Its share of disclosed funding fell from approximately 18 per cent to six per cent. After checking individual announcements and excluding inconsistent entries, I calculated growth of only about four per cent in this range.
From 110 million US dollars to three billion euros: The different costs of scaling AI
Taktile, a Berlin-founded company developing decision technology for financial institutions, raised 54 million US dollars in a Series B in February 2025. By June 2026, it had secured another 110 million US dollars in Series C funding. The company operates in enterprise software, where expansion means winning more customers and making its technology work inside complex banking systems.
Mistral raised three billion euros in September 2026. Developing frontier AI models requires enormous computing resources and research investment. The financing needs of these two companies differ considerably, yet their rounds contribute to the same European AI funding boom.
I also examined funding activity by stage. Tech.eu recorded nine Series A rounds in 2025 and 20 in 2026. Series B went from ten to eight, while Series C declined from six to four. However, the database classified many transactions as ‘Other’, and some stage labels needed correction. These figures are too incomplete to establish a decline in later-stage funding across Europe.
Taktile shows that companies can successfully move through successive funding stages. For other founders, planning that transition means making expensive decisions before they know when the next round will arrive or what terms investors will offer.
The cost of depending on your next funding round
A company may raise capital to enter new markets, hire sales teams and expand its customer base. These plans often assume that another funding round will follow once the business reaches its next growth targets. But expansion can become expensive long before the company reaches those targets.
For an enterprise AI business, new contracts may require extensive customization and ongoing engineering support. Revenue grows, yet the company spends more than expected to deliver it. Hiring commitments and operating costs continue even when progress falls behind the original plan.
This leaves founders in a difficult position. If they need fresh capital to maintain operations, they have less control over the timing of fundraising and the terms investors offer. A more measured expansion strategy may look less impressive in the short term, but it gives management greater freedom to choose when and how to raise its next round.
The next test for Europe’s AI boom
The rapid growth in smaller AI rounds may create a new challenge for Europe’s funding market over the next two years. Some of the companies raising less than 25 million euros today will eventually need 30 million euros, 50 million euros or more to expand. Our analysis shows that this part of the market has grown much more slowly than funding at either end of the distribution.
If the current pattern continues, competition for mid-sized rounds could intensify in 2027 and 2028. More startups may reach the point where they need substantial growth financing, while investors continue to direct exceptionally large sums towards a relatively small group of AI companies.
The next stage will also put more pressure on business fundamentals. Enterprise AI companies that can retain customers and expand without a corresponding rise in operating costs should have an advantage when seeking further investment. Others may face difficult choices about how quickly they can grow and how much capital they can afford to raise.
It will be worth following the companies that secured smaller rounds in 2025 and 2026. Their progression to larger investments, the time between funding rounds and the terms they receive will help establish whether Europe has a genuine growth-capital constraint.
Europe may continue setting AI investment records. The more consequential development over the next few years will be how many of today’s funded startups manage to reach the next stage and build sustainable businesses. That is where the depth of Europe’s AI funding market will become much clearer.
