UK High-Growth Firms Secure £10bn in Foreign Investment as AI Deals Surge

Foreign-backed equity investment in the United Kingdom reached nearly £10 billion in the first half of 2026, highlighting a critical reliance on international capital for scaling domestic innovation. For fintech and tech leaders, this shift underscores a widening gap between seed-stage domestic funding and the massive global liquidity required to move AI and automation firms toward late-stage maturity.

What was announced

The new report, titled Financing the future: How the UK can mobilise global growth capital to drive innovation, reveals that while deals involving foreign investors accounted for less than 10% of UK equity transactions between 2016 and the first half of 2026, they delivered more than half of the total value raised. This is equivalent to £127 billion in capital. The data highlights a distinct "scaleup gap" where domestic investment dominates early-stage and seed rounds, but international capital takes over as businesses mature. In 2025, the median foreign-only deal reached £5.77 million, dwarfing the £0.49 million median for UK-only deals.

Sector-specific data shows a massive surge in interest for artificial intelligence. AI businesses featured in 44.4% of foreign-backed deals in the first half of 2026, a significant jump from 24.3% in 2023. Similarly, robotics and automation saw their share of foreign-backed deals rise from 5% to 19% over the same period. Geographically, the growth is not limited to the capital. Scotland, Northern Ireland, and Wales all recorded stronger growth in foreign-backed investment than London between 2023 and 2025. In Manchester, the average foreign-backed deal was close to £29 million, compared with approximately £3.3 million for domestic-backed transactions. Furthermore, the report found that 75.8% of foreign-backed companies acquired by overseas buyers remain active in the UK, suggesting that international investment does not necessarily lead to an exodus of economic activity.

"The UK has the talent, ideas and expertise to build world-leading businesses, and international investors are recognising that potential. Global capital is helping ambitious UK companies secure the larger investments they need to scale, enter new markets and compete internationally. Importantly, the evidence also shows that businesses backed by overseas investors continue to grow and create value from within the UK. By continuing to attract a broad range of investors and by connecting them with high-potential businesses right across the country, the UK can strengthen its position as one of the world’s leading places to start, grow and finance an innovative business."

What FF News has reported before

FF News recently covered the launch of Barclays to Support 1.5 Million UK Businesses by 2030 with New Growth Initiative, which serves as the broader strategic umbrella for this research. This initiative aims to bolster the foundations of the UK economy by assisting entrepreneurs from the initial idea phase through to an Initial Public Offering (IPO). Additionally, Barclays has been at the forefront of technical innovation in the sector, as seen in our report on how UK Banks Execute First Live Retail Transactions Using Tokenised Sterling Deposits. This move into tokenisation demonstrates the bank's commitment to modernising the financial infrastructure that supports the very businesses identified in the Beauhurst report.

What this means

The reliance on international growth capital for late-stage funding suggests that while the UK is excellent at starting innovative firms, it still struggles to fund their maturity domestically. The surge in AI investment—now nearly half of all foreign deals—places the UK at the center of the global tech arms race, but also makes its most promising firms vulnerable to shifting geopolitical tides and foreign acquisition. The fact that regional hubs like Manchester are attracting significantly higher average foreign deal sizes than domestic ones should put pressure on London-centric venture capital firms to look beyond the M25. The industry must now address whether the UK can develop its own deep-pocketed growth funds to match this international appetite.
