Menlo Ventures Raises $3 Billion — Its Largest Fund in 50 Years — After Turning a Single Anthropic Bet Into a $14 Billion Position
Menlo Ventures has raised $3 billion across two new funds — the largest capital raise in the firm's fifty-year history — fuelled almost entirely by the extraordinary returns generated from a single early bet on Anthropic. Bloomberg reported that Menlo's stake in the AI safety company, built through roughly $1 billion in cumulative investments across multiple rounds, is now worth approximately $14 billion, as Anthropic's valuation has soared above $900 billion. Managing partner Shawn Carolan has described the original commitment as a "bet-the-firm moment" that has since become a template for how conviction-driven venture capital can compound into institutional-scale returns.
The $3 billion is split across two vehicles. Menlo Ventures XVII will write seed and Series A cheques, targeting companies at the earliest stages of formation. Menlo Inflection IV provides growth capital at Series B and beyond, targeting companies that are already pulling away from competitors. The dual-fund structure allows the firm to follow founders from initial spark through hypergrowth — a model that larger rivals such as Andreessen Horowitz, which raised more than $15 billion in early 2026, and Sequoia, which gathered roughly $7 billion for its expansion fund, have long operated. Kleiner Perkins closed $3.5 billion across two AI-focused funds in March 2026. At $3 billion, Menlo is not competing on size alone; it is competing on what TechCrunch described as the compounding power of proximity to category-defining companies.
The Anthropic relationship has produced more than paper gains. In July 2024, Menlo and Anthropic co-launched the $100 million Anthology Fund to back startups building on Anthropic's technology; that fund has since deployed approximately $250 million across more than sixty companies, producing exits including Graphite, acquired by Cursor, and Astrix Security, acquired by Cisco in May 2026, according to TechCrunch. The portfolio now spans AI infrastructure — Axiom, Neon, Skild AI — and applications including Suno, Lovable, and Wispr. Menlo managing partner Matt Murphy, who led the original Anthropic investment, told investors that many of the defining AI companies of the next decade have yet to be built, and that the new funds give the firm the flexibility to partner with founders from formation through hypergrowth.
The raise is also a signal about the structural transformation underway in venture capital itself. As Crunchbase data shows, AI startups captured approximately $242 billion — roughly 80 percent of all global venture funding — in the first quarter of 2026 alone, a step-change from approximately 55 percent in the same period a year earlier. According to PitchBook data cited by Forbes, AI companies captured 81 percent of global venture funding in Q1 2026, absorbing more than $240 billion. Four companies absorbed 65 percent of that total, reflecting a pattern of extreme capital concentration that rewards scale and perceived defensibility over breadth. Late-stage funding reached approximately $246.6 billion in Q1 2026, up 205 percent year-on-year, according to analysis published by Digital Applied.
The honest caveat in Menlo's story, as AI Weekly noted, is that the $14 billion Anthropic valuation remains a paper figure tied to a private company that has not yet gone public. Anthropic has filed plans for a 2026 IPO targeting a valuation of $1 trillion or more, according to Crunchbase. Should that offering materialise at anything close to its target price, Menlo's returns would rank among the most spectacular in venture history — and would validate a playbook of early, concentrated conviction in frontier AI labs that every other major firm is now attempting to replicate. The race to find the next Anthropic before the market catches up, as Menlo's own blog post observed, has never been harder — or more consequential.
