Record AI investment drives strongest UK startup funding since 2022
UK startups and scaleups raised $17bn in venture capital funding during the first half of 2026, marking the strongest opening to a year since 2022 and a 102% increase on H1 2025, according to new analysis from HSBC Innovation Banking UK and Dealroom.
Growth was driven by record levels of AI investment, renewed momentum in late-stage funding and continued strength across deep tech and life sciences, reinforcing the UK’s position as Europe’s leading innovation ecosystem. The UK attracted 39% of all European venture capital investment during the period and raised more funding than the next three largest European markets combined.
AI drives record investment across the UK innovation economy
AI remained the defining theme of UK venture capital investment in the first half of 2026, with AI startups raising a record $12.6bn – accounting for nearly three quarters of all venture capital invested in the UK. Funding was more than four times higher than H1 2025 and almost four times the previous H1 peak recorded in 2022.
AI companies secured 19 of the UK’s 28 megarounds during the first half of the year and accounted for all four $1bn funding rounds completed during the period.
Enterprise software attracted the highest levels of AI investment, raising $5.2bn, followed by health ($2.6bn), hosting ($2.1bn) and robotics ($1.5bn), highlighting AI’s growing impact across the wider innovation economy.
Deep tech and life sciences strengthen the UK’s competitive position
The UK secured 41% of all European deep tech and life sciences funding during the first half of the year, up from 23% in H2 2025, reinforcing its position as Europe’s leading destination for science-led innovation.
UK companies raised $10.3bn across deep tech and life sciences during the period, with major rounds across semiconductors, quantum computing and biotechnology demonstrating the breadth of innovation emerging from the UK’s research and startup ecosystem.
Investors back UK companies at global scale
A surge in late-stage funding drove venture capital investment during the first half of the year, with late-stage rounds accounting for 68% of all capital raised, up from 42% a year earlier and above the European average of 59%.
UK startups completed 28 megarounds of more than $100m, including four funding rounds exceeding $1bn. The largest raises came from Isomorphic Labs ($2.1bn), Nscale ($2bn), Wayve ($1.2bn) and Ineffable Intelligence ($1.1bn).
Rounds of $250m or more accounted for $8.6bn of investment, representing more than half of all venture capital deployed during the first half while breakout-stage companies (Series B and C) raised a further $3.8bn.
UK widens its lead as Europe’s innovation capital
The UK remained Europe’s leading destination for venture capital investment in H1 2026, recording the strongest year-on-year funding growth (102%) among Europe’s largest venture capital markets.
Accounting for 39% of all European venture capital investment, the UK attracted more funding than France, Germany, Sweden and Switzerland combined, strengthening its leadership position across the continent.
The UK innovation economy is now worth $1.7 trillion and is home to 217 unicorns, with a further 18 added so far in 2026. Growth continues to be driven by innovation hubs across the UK, reflecting the depth and geographic diversity of the country’s startup ecosystem. Outside London, Cambridge ($941m), Reading ($379m), Oxford ($240m) and Edinburgh ($160m) attracted the highest levels of venture capital investment, driven largely by AI, deep tech and life sciences companies.
Emily Turner, CEO, HSBC Innovation Banking UK, said: “The first half of 2026 demonstrates the continued strength of the UK’s innovation ecosystem, with record levels of investment reflecting growing confidence from both domestic and international investors. What is particularly encouraging is how AI is increasingly being applied across sectors. We’re seeing it create new opportunities in sectors from life sciences and deep tech to enterprise software, while helping companies compete on a global stage.
“The UK’s combination of world-class research, entrepreneurial talent and access to capital continues to make it one of the most attractive places in the world to build and scale innovative businesses. As success increasingly emerges from innovation hubs across the country, the foundations are in place for the next generation of breakthrough companies to scale globally.”
Technology secretary Liz Kendall said:”The UK is one of the most exciting places in the world to start and scale a tech company, especially in AI. We have the biggest capital pool in Europe, outstanding talent from our world-leading universities and a regulatory environment that is pragmatic, not dogmatic.”
“These investment figures aren’t just theoretical. They mean well-paid jobs and exciting opportunities in some of the fastest-growing sectors for people all across the UK. We are determined to ensure the UK’s tech success works for all in every part of the country. We will continue to back our outstanding tech talent from all backgrounds in every nation and region.”
“The government is committed to ensuring more of world-leading start-ups can scale in the UK and win globally. That is why we recently set up our own Sovereign AI fund, which has already invested in Isomorphic Labs and Ineffable Intelligence, helping to accelerate their success.”
