North American startups raised $392 billion in the first half of 2026, according to Crunchbase data released July 7 -- the largest six-month total ever recorded, and a figure that dwarfs any prior full-year period outside the very top of the 2021 bubble. Q2 alone contributed $137.2 billion, the second-highest quarterly total on record, trailing only the AI-fueled peak set earlier this year.
The number is less a broad-based boom than a single-sector story: roughly 80% of all Q2 investment dollars, across every stage from seed to late-stage, went to AI-focused startups, with AI funding nearly tripling year-ago levels. Late-stage funding hit $101 billion for the quarter, the second-highest total ever, while early-stage funding reached $31 billion, its highest level in more than three years and nearly double what it was a year ago. Seed and angel funding was the conspicuous outlier, falling to $4.9 billion, down 15% from Q1 and 27% year-over-year -- a sign that even as aggregate dollars hit records, the earliest stage of the market is quietly contracting.
The round sizes at the top explain the concentration. Anthropic closed a $65 billion round at a $965 billion post-money valuation, the single largest private financing event of the quarter by a wide margin. Jeff Bezos-backed physical-AI startup Prometheus raised $12 billion, and Anduril Industries closed its $5 billion Series H. All three rounds happened inside a quarter where total deal counts stayed historically low, meaning the record dollar figure is being carried by a small number of enormous checks rather than broad participation across the startup ecosystem.
“Anthropic closed a $65 billion round at a $965 billion post-money valuation, the single largest private financing event of the quarter by a wide margin.”
Exit activity mirrored the concentration at the top: SpaceX's $85.7 billion IPO was the largest in history, pushing its market cap to roughly $1.77 trillion, while SpaceX's separate $60 billion acquisition of Cursor-maker Anysphere was the largest startup acquisition ever recorded. Cerebras Systems and Quantinuum both had major public debuts in the same window, and Eli Lilly's up-to-$7 billion acquisition of Kelonia Therapeutics and Qualcomm's $4 billion purchase of Modular rounded out a quarter as active on the exit side as on the fundraising side.
The comparison to the 2021 funding peak is instructive but imperfect: 2021's record was driven by broad-based enthusiasm across categories and stages, while 2026's record is driven almost entirely by AI infrastructure and a handful of frontier labs, with seed-stage funding actually declining even as the aggregate hits new highs. That's a structurally different, more concentrated version of a funding boom than the market has seen before.
For GPs and LPs, the practical read is that H1 2026's record headline number obscures a market that's simultaneously the easiest it's ever been to raise a nine-figure check for an AI infrastructure play, and one of the harder ones in years to raise a modest seed round outside that theme. Recast Capital's Sara Zulkosky flagged the same dynamic this week, noting that through April, 80% of U.S. venture investment went to rounds of $500 million or more, spread across just 29 companies.
The bear case is straightforward: a record this concentrated in a single sector and a handful of names is also a record this exposed to a single sector's re-rating. If AI infrastructure spending assumptions prove too aggressive -- the exact risk the Bank for International Settlements has already flagged -- H1 2026's record would look less like durable market growth and more like the top of a very narrow cycle.
What to watch: whether Q3 sustains anything close to Q2's pace once Anthropic's and Prometheus's mega-rounds cycle out of the comparison, whether seed-stage funding's decline continues or stabilizes, and whether the exit wave (SpaceX, Cerebras, Quantinuum) continues to absorb the capital being deployed at the top of the market.
