Menlo Ventures Raises a $3 Billion Fund After Its Winning Anthropic Bet
Menlo Ventures has raised a $3 billion fund, the largest in its 50-year history, after a bold bet on AI company Anthropic paid off in a big way. A venture capital (VC) firm is a company that invests money in young startups, hoping a few grow into giants. Menlo is one such firm. Its huge new fund, announced on 23 June 2026, shows how one great AI bet can transform a firm’s fortunes. This is the story of that bet and what the giant Menlo Ventures fund means.
In plain terms: Menlo put a large amount of money into Anthropic, the value of that stake soared, and now Menlo has raised its biggest pool of cash ever to make more bets.
The bet that changed everything
Back in 2024, Menlo led a $750 million investment in Anthropic. Anthropic is the AI lab behind the Claude chatbot, founded by siblings Dario Amodei (its CEO) and Daniela Amodei (its president), both former OpenAI staff. The deal was structured in a clever way. About $500 million came through a special purpose vehicle, or SPV. An SPV is a separate pot of money set up just for one investment, often with outside backers. The other $250 million came from Menlo’s own fund plus insider contributions.
At the time, that round valued Anthropic at $18.4 billion. A “valuation” is the price tag investors put on a whole company. Since then, Anthropic’s value has climbed sharply, and Menlo kept investing in later rounds (called Series E and Series F). Today, Menlo’s stake in Anthropic is reported to be worth around $14 billion. That is a massive gain on the original bet.
Inside the new $3 billion fund
The new $3 billion fund is a milestone. It is the biggest Menlo has ever raised, landing exactly as the firm turns 50 years old. A fund this size lets Menlo write bigger cheques and back more startups across different stages, from young companies to more mature ones. You can read more on that spread in our piece on how Menlo Ventures invests in startup funding across stages.
Menlo’s portfolio already includes a strong list of AI and software names. These include OpenRouter, Higgsfield, Legora, Lovable, and OpenEvidence. A big fund gives Menlo the firepower to keep backing this kind of company as the AI boom rolls on.
The Anthology Fund: Menlo and Anthropic together
Menlo and Anthropic also run a joint effort called the Anthology Fund, launched in 2024. It started with $100 million to back early AI startups. It has since deployed around $250 million and backed more than 60 startups. Some have already had successful exits. (An “exit” is when investors cash out, usually through a sale or stock listing.) For example, Graphite was acquired by Cursor, and Astrix Security was acquired by Cisco.

Why it matters (especially for India and founders)
This story shows the power of conviction investing. Menlo did not spread small bets everywhere. It made a large, focused bet on one company it believed in, and it won big. For founders, the lesson cuts both ways. Investors who believe in you can back you heavily. But that belief is rare and hard to earn.
For Indian founders, the wider message is about timing and AI. Global VC money is flooding into AI, and the firms that backed AI early are now raising record funds. That capital will look for the next big AI ideas worldwide, including in India. The race for AI funding is fierce, as seen in deals like Halobraid’s raise backed by Seven Seven Six. Indian startups that build real AI value can tap into this global wave.
