UK start-ups raised more than $11 billion (£8.2bn) of venture capital in the first half of 2026, surpassing the total for last year – already a record – in just six months, a study from Tech Nation has found.
The funding brought the UK’s tech sector to a total valuation of $1.6tn this year, with 32 percent of the funds raised going to AI, making the UK Europe’s largest AI market, found the study.
Tech Nation, part of the UK-based Founders Forum Group that supports start-ups, unveiled the findings at the AI Stage at London Tech Week, combining data from Dealroom with economic modelling by Thema AI.
New opportunities
The group found that the UK’s AI sector is growing at a compound annual growth rate of 22 percent, with growth over the past three years at three times faster than the equivalent in France and two times faster than in Germany.
The UK now ranks third globally for AI talent, after the US and China, with a workforce of 56,000 and more than 10,000 researchers in the field. Last year alone saw the launch of more than 680 new AI start-ups.
Some 30 percent of UK tech founders said their businesses would not exist without AI, with 40 percent saying they’ve launched new products and services because of the technology and 32 percent launching domain-specific AI agents.
Only 9 percent of UK tech start-ups said they’ve made redundancies.
Perceptions were divided around the rise of major AI platforms in the US, such as Anthropic and OpenAI, with half of UK tech founders saying such platforms have created new opportunities in their industry.
One in four said the rise of Anthropic and OpenAI was forcing them to change strategy, while 30 percent said they were actively reducing their reliance on these third-party platforms by building their own tools – in line with a trend toward tech sovereignty.
Growth across UK
Some 30 percent of founders described AI as a “bubble”.
The growth of AI has extended beyond the capital, with the most significant growth seen in the East of England, Scotland, and the North East. In the South companies are more focused on AI in software, health and biotech, while those in the North are more focused on applying the tech to industry.
Finance and pharmaceuticals/biotech are emerging as the UK’s clearest AI growth sectors, while energy and defence tech seeing the fastest workforce expansion.
Carolyn Dawson, chief executive of Tech Nation and Founders Forum, hailed the strong showing from the UK’s AI ecosystem.
“The task now is to work together – across government, industry, and the startup ecosystem – to ensure the UK leads in an era of AI transformation moving at a pace, scale and level of impact like we’ve never seen before,” she said.
