Key Takeaways
- • Global venture funding reached $91 billion in Q2 2025, up 11% year-over-year from $82 billion in Q2 2024, though down 20% sequentially from Q1 2025's $114 billion high.
- • AI sector captured $40 billion (45% of total global venture funding) in Q2, with Scale AI alone securing $14.3 billion in a single round, representing the most concentrated deployment of capital into a single company this quarter.
- • Capital concentration into mega-rounds intensified: approximately one-third of all Q2 venture capital flowed to just 16 companies raising $500 million or more, underscoring a structural shift toward larger, later-stage funding rounds over broad-based early-stage deployment.
- • Foundation model companies and AI research labs drove sector dominance, with Thinking Machines Lab and Safe Superintelligence (both under one year old) each raising $2 billion, alongside significant rounds from Anduril Industries ($2.5 billion), Grammarly ($1 billion), and Anysphere ($900 million).
- • Healthcare and biotech emerged as the second-largest funding sector at $14.8 billion, but remained substantially below AI's commanding share, reflecting the market's structural reallocation toward artificial intelligence infrastructure and research.
Summary
Global venture funding recovered to $91 billion in Q2 2025, marking the third consecutive quarter above $90 billion and representing an 11% year-over-year increase from $82 billion in Q2 2024, according to Crunchbase data. However, the sequential decline from Q1 2025's $114 billion—the strongest quarter since Q3 2022—suggests moderation in the trajectory after an exceptionally strong opening to the year. Cumulatively, H1 2025 has recorded the strongest half-year for venture funding since early 2022, signaling a sustained recovery in capital deployment after the more constrained venture environment of prior years.
The quarter was characterized by a blockbuster performance in artificial intelligence, which captured $40 billion or approximately 45% of global venture funding. This concentration represents a material acceleration in AI's share of total venture capital and reflects the market's acute focus on foundational AI infrastructure, research capabilities, and enterprise applications. Scale AI's $14.3 billion Series D round alone accounted for a significant portion of Q2's largest funding events and exemplifies the outsized capital requirements of leading AI infrastructure and data companies.
Capital deployment has become increasingly concentrated into the largest funding rounds. Close to one-third of all Q2 venture capital—approximately $30 billion—flowed to just 16 companies raising $500 million or more, demonstrating a structural shift in venture allocation patterns. While capital concentration into mega-rounds was slightly lower than in Q1 and Q4 2024, it remained substantially above historical proportions, indicating that venture capital deployment continues to favor late-stage, well-capitalized companies over early-stage formation.
Within the AI sector, foundation model and AI research companies raised $5.5 billion in Q2. Notable rounds included two AI research labs—Thinking Machines Lab and Safe Superintelligence, both less than one year old—each securing $2 billion. Additional significant AI rounds were raised by defense-focused Anduril Industries ($2.5 billion), productivity software company Grammarly ($1 billion), developer-focused Anysphere ($900 million), and European defense AI firm Helsing ($694 million). Healthcare and biotech companies ranked as the second-largest funding sector with $14.8 billion in venture capital, underscoring AI's dominant but not exclusive positioning in the venture landscape.
The past three consecutive quarters have recorded record funding levels for the AI sector specifically, cementing artificial intelligence as the primary driver of venture capital allocation in 2025. This concentration reflects investor conviction around AI's transformative potential, alongside capital scarcity for non-AI startups, particularly early-stage companies outside the AI supply chain.
