PitchBook report: H1 2026 AI VC hits record $407B; OpenAI and Anthropic dominate half the market

PitchBook's latest Q2 2026 AI Report reveals the astonishing concentration in the AI investment market.

Core Data

• Total VC funding for AI startups in H1 2026: Over $407 billion, far exceeding the $264 billion raised in all of 2025
• Just two companies, OpenAI ($122 billion in March) + Anthropic ($30 billion in Feb + $65 billion in May), account for approx. $217 billion, representing over 50%
• This scale was achieved with only three funding rounds

Structural Divergence

Type	Share of Deal Count	Share of Capital
Vertical Application Companies	62.9%	12.9%
Horizontal Platforms + Frontier Models	37.1%	70.8% ($288.1 billion)

Decline in Deal Volume

• Only about 3,500 deals in H1, compared to 8,290 for all of 2025
• Main reason: Inflation triggered by the Iran conflict raised Fed rate hike expectations; credit tightening made investors more cautious

OpenAI IPO Trends

• Reports indicate OpenAI is considering delaying its IPO to 2027
• Reasons: Internal benchmarks not met + concerns over global market volatility

Analyst Viewpoint

Dimitri Zabelin, Senior Analyst at PitchBook: "The concentration of capital in frontier models reflects investor confidence in OpenAI and Anthropic—not just in expanding their own platforms, but also in the vertical applications built upon them. We expect capital concentration, rather than scarcity, to be the main theme of H2 2026."
