October's filings with the US securities regulator show where the money is going — and one pattern stands out: vehicles that buy stakes in already-priced AI companies are filling faster than classic early-stage funds.
The clearest case is Diffusion ONE. Victor Lazarte and Kris Fredrickson, both formerly of Benchmark, raised $1.252 billion for their debut AI fund, against a target of $800 million reported by Forbes in May. The firm has already written large cheques, co-leading Harvey's $550 million Series H with Lightspeed and taking part in Etched's $300 million Series C in July. A fund overshooting its target by more than half before it is formally marketed says more about the mood than any survey.
The secondary market is becoming the primary one
Industry Ventures has raised at least $1.7 billion for its secondaries fund, which opened in late July. That is no longer a footnote. According to PitchBook analyst Emily Zheng, stakes in Anthropic and OpenAI are "some of the most contested real estate in venture" — and buying them requires a vehicle of that size. The secondary market is thus less an exit path for stressed employees than a procurement market for institutions that missed the private rounds.
Established firms are tooling up too. Benchmark filed what look like four partner-only vehicles — Benchmark Partners Founders' Fund T1, Fund 2, Fund 2-A and T1-A — seeking $220 million, $132 million, $4.5 million and $7.5 million respectively; Jack Altman, who recently joined Benchmark, is listed on all four. 8VC, which raised $1.5 billion for Fund VII in July, is seeking more: $400 million for 8VC DSS III, $30.35 million for 8VC COSC, $20.35 million for 8VC BRSC, and an 8VC AI Fund XI that has already brought in $13.5 million, including from 8VC itself.
Austin's Trust Ventures filed on Monday to raise a $400 million Fund V; the firm backs founders in heavily regulated industries and had sought a $225 million Fund IV in 2023. Deep-tech fund Interlagos Capital is raising a $400 million Fund II. Notable Capital — an investor in Anthropic, Airbnb and Square — and Neil Mehta's Greenoaks, which co-led Anthropic's Series H, have also filed for new funds.
What it means for founders
Two things. First, capital for AI startups is plentiful but concentrated in a handful of names and in late stages. A fund that raises $1.25 billion and spends it on Harvey and Etched is not the early-stage investor you send a pre-seed deck to. Second, the pressure to produce exit narratives is rising, because the LPs in these vehicles need returns computed against already very high marks. Anthropic's listing is the first real test of whether the arithmetic holds.
