In the high-stakes world of AI venture capital, one firm has pulled off a move that will be studied for decades. Menlo Ventures announced on June 23 that it had raised $3 billion in new capital — the largest fundraise in its 50-year history — and the announcement is inseparable from a single, remarkable position: its bet on Anthropic.
A $14 Billion Paper Gain
Menlo's cumulative $1 billion investment in Anthropic across multiple rounds, starting at Series C in 2023 when the company was pre-product and pre-revenue, is now worth approximately $14 billion based on Anthropic's $965 billion post-money valuation. That represents a 14x return on the total investment, with the earliest positions carrying even higher multiples.
Managing partner Shawn Carolan called the original Anthropic commitment a 'bet-the-firm moment.' At the time, Menlo structured much of the $500 million Series D lead as a special-purpose vehicle — an unusual move — when no other VC was writing half-billion dollar checks in the post-pandemic venture winter.
The Anthology Flywheel
The firm's strategy went beyond writing a check. In 2024, Menlo co-launched the Anthology Fund with Anthropic — a $100 million startup vehicle (now deployed closer to $250 million) that provides early-stage AI startups with access to Anthropic leadership and Claude credits. The fund has backed 60+ companies and produced three exits: Graphite (acquired by Cursor), Astrix Security (acquired by Cisco), and Fintool (acquired by Microsoft).
Notable current portfolio companies include OpenRouter, Higgsfield, Suno, Lovable, OpenEvidence, Axiom, and Skild AI.
The IPO Countdown
The $14 billion figure remains a paper gain until Anthropic's planned October 2026 IPO converts it to public market value. At its current $965 billion valuation, an IPO at or above $1 trillion would make Anthropic the highest-valued company to ever go public. Menlo has not yet distributed those gains to limited partners — the path from paper to realized return runs through the public listing and a subsequent lockup period.
'Whether the $1 trillion narrative survives the dual scrutiny of an IPO roadshow and simultaneous OpenAI (September) and SpaceX competitive comparisons is the open question the $3 billion raise is betting on,' analysts noted.
A New Fund Structure
The $3 billion is split between Menlo Ventures XVII (focused on seed and Series A) and Menlo Inflection IV (Series B and growth), giving the firm the ability to write checks at every stage — a structural shift from its traditional early-stage identity.
'This isn't just a fundraise — it's a declaration that the AI wave is creating generational returns,' said one limited partner who invested in the new fund. 'Menlo's Anthropic position is the proof case for the entire thesis.'
