Busiest venture firms did more Q3 deals while total funding fell, Crunchbase data shows

Crunchbase says AI drove most of Q3's dealmaking ^[17]. At the top of its dollar rankings, that comes down to a few financings. Andreessen Horowitz's tally is mostly two deals: $2 billion for Cognition plus $1.7 billion for Atoms is $3.7 billion, about 57% of the total ^[10][19]. Nvidia's is mostly one, with Safe Superintelligence at about 79% ^[20].

The two tied leaders cannot be added together. Valor's and Atreides' tallies sum to $15.4 billion, but Crusoe's $3.9 billion Series F and Positron's $375 million Series C count in both, so the two firms led at most about $11.1 billion of distinct rounds, before netting out their other shared deals ^[8][23]. If each firm's 10 lead deals make up its $7.7 billion, that is roughly $770 million a round ^[6][21]. Crunchbase names the pair as firms that are significantly scaling up their investments ^[16]. Insight led more rounds than anyone, yet it is not among the four top spenders Crunchbase named ^[6][9].

Y Combinator's ranking measures something else. Its 45 post-seed deals are largely follow-on rounds for startups it incubated, so first place there mostly reflects money going back into its own portfolio ^[4]. Counting seed, YC was in at least 266 rounds in the quarter ^[22].

There are three plausible explanations for the lower total. One is timing. Record AI megarounds, whose absence Crunchbase links to the decline ^[1], arrive in lumps. A quarter without one lowers the sum while deal counts carry on. The second comes from a companion Crunchbase headline about AI giants eyeing the public markets ^[15]. If the largest companies raise money through listings, the private total loses its biggest component for good, however busy venture firms stay. The third explanation cuts against the busy-investor reading. Crunchbase says the highest-spending lead investors appeared to put less capital to work ^[3]. A firm doing more deals with fewer dollars may simply be writing smaller checks out of caution.

I think the first two explanations fit the evidence better. A majority of the busiest investors added deals ^[2], and the top lead investors also largely picked up their pace ^[3]. The third is still possible. Crunchbase's piece does not give the size of the decline or each firm's deal count for the prior quarter, so these tables cannot rule out a move to smaller checks. The thesis fails if record AI rounds come back and the busiest firms' deal counts fall anyway.
