SEC Filings Uncover October’s Surge in Venture Capital Fundraising: Oversubscribed Vehicles, Unannounced Flagships, and Hot Secondaries Growth

Per newly published U.S. Securities and Exchange Commission regulatory disclosures, October was an unusually active month for venture fundraising. The filings confirm that established, niche-focused venture firms are currently securing unprecedented large capital commitments from limited partners, with specialized strategies earning particularly outsized allocations. Below are the most high-profile unannounced fund raises and underreported fundraising updates that surfaced in the latest batch of public paperwork:

Austin-based regulatory industry specialist Trust Ventures filed paperwork earlier this week to raise a $400 million fifth flagship fund, Fund V. Founded in 2017 by Salen Churi, the firm focuses exclusively on backing founders building products and services in heavily regulated sectors, a high-upside niche that landed a notable anchor commitment from Koch Disruptive Technologies for its debut fund back in 2018. The shop previously filed to raise a $225 million Fund IV in 2023, and no public record of a final close or confirmed total capital for that prior vehicle has been released to date.

Deep tech-focused investment firm Interlagos Capital is also targeting $400 million in commitments for its second flagship fund, per its newly posted SEC filing.

Two former Benchmark general partners, Victor Lazarte and Kris Fredrickson, have already locked in $1.252 billion for their debut dedicated AI fund, named Diffusion ONE. Forbes first reported the pair’s joint venture back in May, noting that after running separate smaller independent funds for years, the two partnered to launch the AI-focused vehicle with an initial $800 million fundraising target — meaning the final raise has blown past that original goal by more than 50%. The new fund has already been active on the deal circuit: it co-led legal AI startup Harvey’s $550 million Series H round alongside Lightspeed Ventures, and participated in Etched’s $300 million Series C announced in July.

Sticking with Benchmark, the iconic Silicon Valley firm also filed paperwork for four new partner-exclusive vehicles, formally named Benchmark Partners Founders’ Fund T1, Benchmark Partners Founders’ Fund 2, Benchmark Partners Founders’ Fund 2-A, and Benchmark Partners Founders’ Fund T1-A, with respective fundraising targets of $220 million, $132 million, $4.5 million, and $7.5 million. All four filings list Jack Altman — the prominent founder and investor who recently departed his own firm to join Benchmark as a general partner — as a named managing member.

Joe Lonsdale’s 8VC is also gearing up to raise a suite of new targeted vehicles, per its latest regulatory filings. The lineup includes a $400 million flagship vehicle named 8VC DSS III, a $30.35 million 8VC COSC fund, a $20.35 million 8VC BRSC fund, and the 8VC AI Fund XI, which has already closed $13.5 million in commitments to date, including a capital contribution from 8VC’s own balance sheet. The new filings come just months after 8VC announced in July that it had secured $1.5 billion in total commitments for its seventh core flagship fund.

Earlier this October, Notable Capital — the early backer of breakout household names including Anthropic, Airbnb, and Block (formerly Square) — filed to raise its fifth flagship fund. Meanwhile, Neil Mehta’s Greenoaks Capital, which co-led Anthropic’s record-breaking $65 billion Series H round, also filed SEC paperwork for its upcoming seventh fund, Greenoaks 7. The timing of these fundraising efforts lines up perfectly with Anthropic hitting a major new milestone on its path to public listing, giving both firms a clear, high-profile exit track record to market to new LPs as they pitch for fresh capital. Per PitchBook data, Greenoaks’ portfolio also includes fintech unicorn Ramp alongside its landmark Anthropic stake.

Elsewhere on the fundraising front, Industry Ventures has locked in at least $1.7 billion in commitments for its latest secondaries fund, which first opened for fundraising at the end of July. The outsized size of the vehicle underscores just how rapidly the venture secondaries market has grown in recent quarters, as investor appetite surges to pick up stakes in high-flying late-stage private companies gearing up for liquidity events. Multiple industry insiders have noted the red-hot demand for these secondary shares as of late: one family office advisor spoke to TechCrunch last month about the explosive mainstream popularity of the secondaries market, while PitchBook senior venture analyst Emily Zheng noted that minority stakes in top generative AI leaders Anthropic and OpenAI are now effectively the “most contested real estate in the entire venture ecosystem.”
