Menlo Ventures Raises $3B After Its Anthropic Bet Pays Off Spectacularly

Menlo Ventures has raised $3 billion in fresh capital, the largest haul in the firm's 50-year history — and a victory lap for what managing partner Shawn Carolan once called a "bet-the-firm moment" on Anthropic.

The capital is split across two vehicles: Menlo Ventures XVII, which will back companies from seed through Series A, and Menlo Inflection IV, aimed at Series B and later growth-stage rounds.

The Bet That Made the Firm

In 2024, Menlo raised roughly $500 million — an unusually aggressive move at a time when the venture world was still nursing post-pandemic wounds and giants like SoftBank and Tiger Global were digesting losses — largely to invest in Anthropic's Series D. The firm pooled capital through special purpose vehicles and wrote what it described as the largest check in its history, a round that quadrupled Anthropic's valuation to $18 billion.

Menlo didn't stop there. It has invested roughly $500 million more across Anthropic's subsequent rounds, participating in the Series E and F. That conviction has been rewarded: with Anthropic's valuation now topping $900 billion, Menlo's stake is worth nearly $14 billion. An Anthropic IPO is expected in October 2026 at a valuation above $1 trillion, which would rank among the defining venture outcomes of the AI era.

All In on AI

The new funds formalize a strategy Menlo has been executing for years. The firm says it is investing across three layers of the AI stack: frontier models and infrastructure, AI-native applications in enterprise, healthcare, and consumer, and emerging hardware.

Its Anthology Fund — a $100 million vehicle launched jointly with Anthropic in 2024 — has since deployed roughly $250 million across more than 60 companies, and has already notched exits including Graphite, acquired by Cursor, and Astrix Security, acquired by Cisco. Menlo's broader AI portfolio includes OpenRouter, Higgsfield, Legora, Lovable, and OpenEvidence.

Fifty Years, One Defining Decade

Founded in 1976 by H. DuBose Montgomery, then a 27-year-old Bell Labs engineer, Menlo has ridden every major technology wave since. But the Anthropic position is shaping up to be the firm's defining investment — one first made in 2023, when the AI lab was still pre-product.

For limited partners, the $3 billion close is a straightforward signal: the firm that bet everything on Anthropic wants to do it again, across the entire AI landscape. In a fundraising market that remains selective, Menlo's record-setting raise shows that a single well-timed conviction bet can still reset a firm's trajectory — and its standing with LPs — for years to come.
