AI Startup Funding Q2 2025: $50B in a Quarter as Infrastructure and Agent Startups Lead

Global AI startup funding hit $50 billion in Q2 2025, with infrastructure plays (compute, MLOps, data infrastructure) claiming 35% of investment and AI agent startups capturing 28%. The median Series A for AI-native startups reached $18 million, triple the 2022 median. Notably, enterprise AI application companies with proven ARR are now raising at 15-25x revenue multiples, while pure research plays without clear monetization paths are struggling to close rounds.
