TLDR: Venture capital investment in artificial intelligence has seen an unprecedented surge in the first half of 2025, with global funding for generative AI reaching $49.2 billion, surpassing the total for all of 2024. This growth signifies a strategic shift towards more mature AI companies capable of demonstrating real-world impact, as highlighted by EY’s latest research. Major deals involving industry giants like OpenAI, xAI, and Databricks underscore this trend, with the U.S. dominating the investment landscape.
Venture capital (VC) investment in artificial intelligence, particularly generative AI, has experienced a remarkable boom in the first half of 2025, according to a recent study by EY Ireland. Global funding for generative AI surged to an impressive $49.2 billion in the first six months of the year, significantly outpacing the $44.2 billion recorded for the entirety of 2024 and more than doubling the $21.3 billion total from 2023. This substantial increase signals a pivotal shift in investor strategy within the AI sector.
The research indicates a clear pivot by VC investors from early-stage generative AI startups to more established, later-stage companies. The average deal size has tripled year-on-year, reaching $1.5 billion, reflecting a preference for more substantial investments in platforms that can demonstrate tangible real-world impact and a clear return on investment. Grit Young, EY Ireland’s technology, media, and telecoms lead, commented on this trend, stating, “We are seeing a clear pivot to less but more substantial investments, which are pointed towards more mature companies and platforms that can demonstrate they can deliver real-world impact and return on investment.”
The United States continues to dominate the global AI investment landscape, accounting for a staggering 97% of the global deal value and 62% of the volume. In contrast, the EMEA region, while making up 23% of the deal volume, only represents 2% of the total deal value. Overall U.S. venture capital funding in the first half of 2025 reached $145 billion across North America, with AI startups alone capturing $104.3 billion, representing over half of the total VC investment in the region.
Several high-value investments have characterized this period of growth. Notable funding rounds include SoftBank’s commitment to OpenAI, which could reach up to $40 billion, and xAI’s $10 billion funding round. Other significant investments include Databricks securing $5 billion, Anthropic raising $3.5 billion, and Mistral AI and Harvey each receiving $600 million. In the second quarter of 2025, Meta’s $14.3 billion stake in data labeling and model evaluation startup Scale AI was the largest AI investment, while Anduril secured a $2.5 billion investment, doubling its valuation to $30.5 billion.

Despite a general decline in the overall number of VC deals across the market, AI-related deals have remained relatively stable, indicating sustained investor confidence in the sector. While global startup funding reached $91 billion in Q2 2025, marking an 11% year-over-year increase, it also represented a 20% quarter-to-quarter drop. However, the first half of 2025 stands as the strongest half-year for venture investment globally since the first six months of 2022, signaling a tentative recovery in private markets driven primarily by AI innovation.
