UK private markets showed mixed momentum in the second quarter of 2026, according to data from PitchBook, as artificial intelligence investment and government policy initiatives shaped dealmaking activity.

Venture capital activity remained resilient, supported by another wave of AI megadeals, notably a large round by Isomorphic Labs, a subsidiary of Alphabet focused on AI-driven drug discovery. The government has also deepened its commitment to AI, with new pledges to expand computing infrastructure and semiconductor investment aimed at bolstering the UK's long-term competitiveness in the technology sector.

Private equity dealmaking rebounded from a softer start to the year, driven by several large buyout transactions. However, fundraising in the PE segment remained subdued, reflecting broader macroeconomic uncertainty and a weaker exit environment. Overall, capital continues to concentrate in AI and larger transactions, while liquidity constraints and cautious investor sentiment persist.

International Context
The UK's push to position itself as a global hub for AI investment aligns with similar efforts by other major economies, including the United States, the European Union, and China. Government-backed computing infrastructure and semiconductor initiatives are part of a wider trend of state intervention to secure technological sovereignty. The concentration of capital in AI megadeals also mirrors global patterns, where venture capital increasingly flows into a few high-value transactions rather than a broad base of startups.

Verified Analysis
Available evidence from PitchBook indicates that while AI investment is a bright spot, the broader UK private market faces headwinds from high interest rates and geopolitical uncertainty. Expert consensus suggests that without a sustained improvement in exit markets, fundraising recovery may remain sluggish. The government's policy support for AI is seen as a positive signal, but its impact on deal flow will depend on timely implementation and complementary private-sector investment.

Future Developments
Looking ahead to the next 2–5 years, the UK private market is expected to see continued policy-driven investment in AI and related infrastructure. Business response will likely involve scaling AI startups and attracting foreign capital. However, the exit environment may take time to normalize, and fundraising could remain selective. Market developments will hinge on global economic conditions and regulatory evolution. International cooperation on AI governance and cross-border investment will also shape the UK's competitive position.
