Artificial intelligence firms accounted for 61% of global venture capital (VC) investment in 2025, or USD 258.7 billion out of a total USD 427.1 billion, more than doubling AI’s share since 2022 (30%) according to new OECD analysis of VC data.
Since 2023, AI firms focused on IT infrastructure and hosting have attracted the largest volumes of VC, reaching USD 109.3 billion in 2025 alone. Cumulative investment in this sector totalled USD 256.1 billion between 2012 and 2025, reflecting the strategic importance of compute infrastructure for scaling advanced AI systems.
VC investors in the United States remain the most active, representing about 56% (USD 124 billion) of the worldwide value of outgoing VC investments in AI in 2025, followed by investors in the United Kingdom at 9% (USD 20.7 billion), China at 8% (USD 17.2 billion) and EU27 investors at 7% (USD 14.5 billion). Firms based in the United States attracted about 75% (USD 194 billion) of global AI VC deal value, followed by the EU27 (6%, USD 15.8 billion), the People’s Republic of China (hereafter ‘China’) (5%, USD 13.9 billion), and the United Kingdom (5%, USD 13.8 billion).
AI VC investments are increasingly concentrating in “mega deals” exceeding USD 100 million. Since 2023, the share of AI VC coming from early-stage investment rounds relative to later funding rounds has been declining, as mega deals account for about 73% of total AI investment value in 2025. Of these mega deals, deals above USD 1 billion represent roughly half of total AI investment value, indicating an increasingly concentrated market.
While long-term prospects for AI remain strong, venture capital markets are cyclical. These findings point to the scale and direction of recent investment trends, but should be interpreted with caution when assessing future developments.
