Menlo Ventures Raises $3 Billion on the Strength of a Single Anthropic Bet — and Plans to Do It Again
Menlo Ventures has raised $3 billion across two new funds, the largest capital raise in its 50-year history, Bloomberg reported on June 23. The firm disclosed the fundraise on its 50th anniversary and split the capital between two vehicles: Menlo Ventures XVII, which will deploy at seed and Series A, and Menlo Inflection IV, a growth fund for companies at Series B and beyond. The raise represents a dramatic scaling of ambition for a firm that only a few years ago was a mid-sized generalist investor, and it is almost entirely attributable to a single, audacious early wager on Anthropic.
Menlo first backed Anthropic in 2023, when the AI safety company had no product and no meaningful revenue. The firm went on to lead Anthropic's Series D, writing the largest single cheque in its history through a structure that combined a special-purpose vehicle with contributions from its own fund. Menlo's total investment in Anthropic now stands at roughly $1 billion, according to Bloomberg, and that stake is reportedly worth approximately $14 billion as Anthropic's valuation has soared to more than $900 billion. Managing partner Shawn Carolan has referred to the original commitment as a bet-the-firm moment; from the outside, it reads exactly that way. Crunchbase reported that Anthropic has now overtaken rival OpenAI as the top-valued frontier lab in the world at a staggering $965 billion valuation, and has filed plans for a 2026 IPO expected to target more than $1 trillion.
The breadth of Menlo's current AI portfolio illustrates how one successful position compounds into an entire strategy. In partnership with Anthropic, the firm launched the $100 million Anthology Fund in July 2024, which has since deployed roughly $250 million across more than 60 early-stage companies building on Anthropic's technology, with three exits already recorded, including Graphite's acquisition by Cursor and Astrix Security's acquisition by Cisco. More recent bets include $100 million each in Lovable, the Swedish AI coding startup valued at $6.6 billion, the music-generation platform Suno, and voice-dictation company Wispr, according to The Next Web. The firm also has positions across AI infrastructure players including OpenRouter, Axiom, Goodfire, and Skild AI.
The broader venture landscape into which Menlo is deploying this capital has itself been transformed. According to PitchBook data reported by Forbes, AI companies captured 81% of global venture funding in the first quarter of 2026 alone, absorbing more than $240 billion in capital. Crunchbase data shows that investors poured $300 billion into startups globally in Q1 2026, an all-time high. The largest firms are scaling to match: Andreessen Horowitz raised more than $15 billion across six funds in early 2026, Kleiner Perkins closed $3.5 billion across two AI-focused funds in March, and Sequoia gathered roughly $7 billion for its expansion strategy fund. At $3 billion, Menlo is not competing on scale alone but on proximity, arguing that its Anthropic relationship gives it an intelligence advantage on the AI stack that capital alone cannot replicate.
The critical caveat to the Menlo story is that its Anthropic gains remain on paper. The stake is valued against a private market price above $900 billion, and the path from paper to realised cash runs through either an IPO or secondary sales at a moment when AI valuations are historically elevated. As TechCrunch noted, Menlo has not yet distributed those gains to its limited partners. The question for the firm's new funds is whether the next decade can produce another position of comparable magnitude, or whether the Anthropic windfall is a once-in-a-generation event that funded a permanent strategic upgrade. If Anthropic's IPO proceeds at or above its current implied valuation, the answer will define not just Menlo's future but the template for how specialised AI venture firms justify their existence in an era of trillion-dollar private companies.
