Menlo Ventures Hits a Three Billion Dollar Jackpot After Going All In on Anthropic

Menlo Ventures just locked in three billion dollars in fresh funds. This marks the biggest capital raise in the firm’s 50-year history, and a massive portion of that success comes down to a single, aggressive bet on artificial intelligence. Specifically, their early and heavy backing of Anthropic has put them in an incredibly strong position. Because of that move, Menlo’s total stake in the AI model creator has soared to an estimated value of 14 billion dollars.

Looking back, the team at Menlo Ventures admits they were white-knuckling it when they first orchestrated their massive investment strategy. In 2024, they led a 750 million dollar funding round for Anthropic, effectively pre-empting the startup’s Series D round. That bold move caused the AI company’s valuation to jump by four times, landing at 18.4 billion dollars.

While investing in a premier AI lab might look like a no-brainer today, the way Menlo actually pooled the money was highly unusual and carried significant risk. Menlo had already backed Anthropic during its Series C round, back before the startup even launched its core products like Claude Code and Claude Mythos. At that time, Anthropic was already showing immense promise. It had secured a four billion dollar partnership with Amazon and was being hunted by top-tier venture capitalists. The startup had a stellar pedigree, founded by former OpenAI researchers and siblings Dario Amodei and Daniela Amodei.

The real shockwave was how Menlo structured the cash in 2024. The venture capital landscape was still freezing cold, recovering from a brutal post-pandemic downturn. Giant investment firms like SoftBank and Tiger Global were still nursing their wounds from previous losses, and almost nobody was writing massive checks. Menlo did not have 750 million dollars just sitting around in their main fund, so they got creative. They structured roughly 500 million dollars of the deal through a special purpose vehicle, which is a one-off investment entity built to pool cash from multiple outside sources for a single, specific deal. Menlo contributed 250 million dollars from its own main fund and tapped firm insiders to bridge the rest.

Since that gamble, these types of single-company investment funds have exploded across Silicon Valley. They became so common that Anthropic itself had to issue a public warning to crack down on unauthorized entities and secondary markets trying to sell fake or unapproved shares of its stock.

For the investors who trusted Menlo’s wild 2024 play, the aggressive push paid off beautifully. The TechCrunch article layout shown in image_bef7c3.jpg underscores this massive win. Menlo did not stop with that single round. They kept pushing forward, investing in Anthropic’s later Series E and Series F rounds.

On top of those core investments, Menlo launched a specialized 100 million dollar startup fund called Anthology in late 2024, which specifically backs companies building on top of Anthropic’s technology ecosystem. That specialized fund has since grown significantly, deploying close to 250 million dollars into the ecosystem. According to insiders, Menlo has backed more than 60 companies through this program, offering them deep perks like credits for Claude and direct access to Anthropic’s leadership team. The strategy has already yielded major returns, including startups like Graphite, which was acquired by Cursor, and Astrix Security, which Cisco bought.

This deep relationship gives Menlo an unmatched view of the early-stage AI landscape. Their massive new three billion dollar fund will allow them to keep hunting for the next wave of tech giants, building on an active portfolio that already includes rising AI stars like OpenRouter, Higgsfield, Legiti, Lovable, and OpenEvidence.
