Anthropic backers dominate Q2 US venture spending
Established venture firms captured the bulk of second-quarter US startup funding, concentrating capital heavily in a small number of massive AI deals.
Second-quarter US venture capital activity remained in high gear, but capital deployment was heavily concentrated among a familiar roster of established players. A small cluster of elite firms, particularly those with positions in Anthropic, accounted for the vast majority of mega-round check-writing.
The highest-spending investors were defined by their exposure to a single generative AI developer. Anthropic’s $50 billion Series H in May featured 10 co-lead investors, dominating the aggregate value rankings. Google and Amazon also featured prominently among the top spenders, having led separate $10 billion and $5 billion tranches, respectively.
Broad deal volume was similarly dominated by incumbents. Per Crunchbase data, General Catalyst, Y Combinator, and Andreessen Horowitz were the most active post-seed investors, closing 39, 34, and 28 deals respectively. More than two-thirds of these transactions were directed at AI-focused startups, confirming where venture priorities currently lie.
When isolating for lead investors, the hierarchy shifted slightly but remained concentrated. Andreessen Horowitz took the top spot by leading or co-leading 17 rounds. Khosla Ventures and General Catalyst followed with 13 led rounds each. Overall, at least a dozen investors led six or more venture rounds during the quarter.
For market participants, this data underscores a highly concentrated risk profile in venture capital. While 23 different investors led or co-led US rounds valued at $2 billion or more, the sheer weight of capital flowing into a single AI company highlights a market reliant on blockbuster bets rather than broad-based deployment.
The dominance of established names extended down to the earliest stages of company formation. Y Combinator easily retained its rank as the most active seed investor, participating in at least 225 seed, pre-seed, or convertible note rounds for newly formed startups. Antler and LvlUp Ventures followed as distant second and third players.
The aggregate rankings portray a funding ecosystem characterized by vibrant, high-volume activity that is nonetheless tightly controlled by a few key gatekeepers. Institutional money continues to flow freely into the startup economy, but the overwhelming focus on artificial intelligence suggests limited capital dispersion for the broader market.
