Global venture capital funding totaled about $159 billion across roughly 6,000 startups in the third quarter, according to data published by Crunchbase News on October 5. That is down 25% from the second quarter's $212 billion, but still up 53% from the $104 billion raised in the third quarter of 2025 — a reminder that even a quarter-over-quarter pullback is landing on an unusually high base.
The slowdown in total dollars masks a different trend underneath: concentration at the very top of the market. A record 27 companies raised rounds of $1 billion or more in the quarter, up from 16 in the second quarter and 14 in the first, and those mega-rounds alone accounted for roughly a third of all global venture capital raised in the period. Eight of those rounds were $3 billion or larger, led by Databricks and Safe Superintelligence, which each closed $5 billion rounds, according to the same Crunchbase analysis.
AI remained the dominant theme by a wide margin. AI-focused startups raised $102 billion in the quarter, about 64% of global venture capital, continuing a run in which the category has absorbed an outsized share of available capital for well over a year. Geographically, U.S.-based companies took in about $91 billion, or 57% of the worldwide total, and the San Francisco Bay Area alone accounted for 24% of all venture dollars deployed globally — a sign of how tightly AI fundraising remains clustered around a handful of firms and a single region.
Still a boom, just a narrower one
Zoomed out, 2026 remains a record year for venture capital. Funding through the first three quarters reached $679 billion, the highest first-three-quarter total Crunchbase has on record, and even this year's weakest quarter so far outpaced every quarter since the second quarter of 2022. The question raised by the mix of numbers is less about the overall size of the pool and more about who is drinking from it: with roughly a third of all capital going to 27 companies, and nearly two-thirds going to one sector, the venture market that smaller, non-AI startups are raising into looks considerably tighter than the headline totals suggest.
Whether that concentration eases will depend largely on how the fourth quarter shapes up. If AI infrastructure financing keeps pace with the first three quarters, 2026 is on track to set a full-year funding record — but one increasingly defined by a small number of giant checks rather than a broad base of early-stage activity.
