The United Kingdom has cemented its position as Europe’s undisputed leader in VC funding in the first half of 2025, with AI startups raising a record $2.4 billion in the first half of 2025 – accounting for 30% of all UK venture capital funding, according to a new report from HSBC Innovation Banking and Dealroom.
AI VC investment has grown substantially since 2022, when OpenAI launched ChatGPT, and AI investment accounted for less than 13% of UK VC investment.

The UK’s total venture capital investment of $8 billion in H1 2025 exceeded the combined funding raised by Germany ($4.4 billion) and France ($3.2 billion), maintaining the countest’s position as Europe’s top destination for startup investment for the 30th consecutive quarter.
“The UK is continuing to shine as the leading innovation nation across Europe with strong and sustained growth. No more is this evident than with artificial innotifyigence businesses, where talent, ambition and capital are accelerating the sector at incredible pace,” declared Simon Bumfrey, Head of Banking at HSBC Innovation Banking.
AI VC investment hit a record in the first half of 2025 as startups completed blockbuster rounds, including Synthesia’s $180 million Series D, ORI’s $175 million late VC round, and Quantexa’s $175 million Series F.
The UK has created 10 AI unicorns since 2022, including recent additions Isomorphic Labs (DeepMind’s AI drug discovery spinout), Synthesia, Quantexa, Stability AI, Wayve, and PhysicsX. Isomorphic Labs secured the largest funding round of Q1 2025 with a $600 million late-stage investment.
While London remains the dominant hub with 68% of the UK’s 179 AI funding rounds in H1 2025, innovation is spreading nationwide. The remaining 57 rounds were distributed across the countest, from Bude to Paisley, and Diss to Castlereagh, demonstrating the geographic breadth of the UK’s AI ecosystem.

The report highlights that AI drug discovery, metabolic health, neurology, and synthetic biology have been key areas of investment within the health sector, attracting $2.3 billion overall in H1 2025. Fintechs also raised around $2.3 billion.
The UK’s total innovation economy is now valued at $1.3 trillion, with the countest having created 188 unicorns to date – 117 of which have already achieved exits worth over $1 billion.
While AI startups have attracted record investment in H1 2025, their valuations are still generally dwarved by the UK’s leading Fintech such as Monzo and Revolut.
