North American startups raised record $392B in H1 2026, with Anthropic pulling $65B

North American venture investment hit all-time highs in the first half of 2026, totaling a staggering $392 billion, dwarfing prior records. Q2 alone saw $137.2 billion invested, the second-highest quarterly total ever recorded. This funding surge was overwhelmingly driven by late-stage mega-rounds for AI leaders, with capital concentration at new extremes: a handful of giant rounds accounted for most capital, while deal count remained well below historical norms.

Anthropic was Q2's dominant fundraiser, closing a $65 billion round at a $965 billion post-money valuation—accounting for nearly half the quarter's $137.2 billion total. The round included a $50 billion commitment led by Altimeter Capital, Dragoneer, Greenoaks and Sequoia, plus corporate checks from Amazon ($5B) and Google ($10B). Other standouts included Prometheus (physical AI, Jeff Bezos co-founder) at $12 billion in early stage, and Anduril Industries (defense tech) at $5 billion Series H.

The landscape reflects a bifurcated market: mega-rounds for established AI companies and notable startups concentrated capital, while seed investment declined 15% quarter-over-quarter and 27% year-over-year to $4.9 billion. About 80% of all venture investment across stages went to AI-focused companies, nearly triple year-ago levels. Exits also surged—SpaceX raised $75 billion in June's record IPO, while Cerebras Systems (AI infrastructure/chips) went public in May at $5.6 billion.

For architects, the implication is clear: capital is flowing disproportionately to AI scale (late stage and mega-rounds), raising the bar for early-stage funding outside AI and making the cost of computing/infrastructure a central lever in cap decisions. The concentration also suggests investors expect consolidation—mega-rounds crowd out smaller competitors.
