UK startups reportedly raised $17B in first-half funding on AI boom

The Times reports that UK startups raised $17 billion in the first half of 2026, double the comparable 2025 figure, according to Dealroom and HSBC Innovation Banking data. AI companies reportedly drew about $12.6 billion, close to three quarters of the total, with major rounds for companies such as Isomorphic Labs, Nscale, Wayve, and Ineffable Intelligence. The report also notes a continuing weakness in domestic scale-up capital, with many large rounds still dependent on non-UK investors.
