From $750M to $14B: Menlo Ventures AI investment reshapes VC

A $3 billion fundraise doesn’t happen by accident. For Menlo Ventures, it happened because of a single, high-stakes conviction bet on Anthropic — one that its own partners describe as a white-knuckle moment — and because that bet paid off in a way that has reshaped what venture capital firms think is possible in the AI era.

Key takeaways

• Menlo Ventures raised $3 billion, the largest fund in its 50-year history, driven primarily by its AI portfolio and Anthropic stake.
• Menlo led Anthropic’s 2024 Series D with a $750 million investment, structuring roughly $500 million of it through a special purpose vehicle (SPV).
• Anthropic’s valuation quadrupled to $18.4 billion after the Series D; Menlo’s stake is now reportedly worth around $14 billion.
• The jointly launched Anthology fund started at $100 million in 2024 and has since deployed approximately $250 million across more than 60 companies.
• Anthropic has publicly warned investors that unauthorized SPVs and secondary market claims to sell its stock are scams.

Menlo Ventures Raises $3 Billion in Its Largest-Ever Fund

The new fund is the biggest in Menlo Ventures’ half-century of existence. That milestone alone signals something meaningful — but the more interesting story is how the firm got there. Its Menlo Ventures Anthropic investment didn’t just generate returns; it functionally rebuilt the firm’s reputation and fundraising power in one move.

According to Bloomberg, Menlo’s stake in Anthropic is now worth approximately $14 billion. For a firm that committed $750 million at the Series D stage, the math is striking enough to attract serious limited partner interest at a scale Menlo had never previously reached.

The timing matters too. In 2024, venture capital was still clawing its way out of a post-pandemic freeze. Firms like SoftBank and Tiger Global were still absorbing losses. Writing a check of three-quarters of a billion dollars into a single AI company — before it had a fully mature commercial product — wasn’t a consensus call. It was a conviction call.

Key Role of Anthropic in Menlo’s AI Investment Strategy

Menlo had been an early Anthropic backer, entering before the company had a product on the market. By 2024, the signals had strengthened considerably. Anthropic had secured a $4 billion commitment from Amazon, was founded by former OpenAI researchers including CEO Dario Amodei and President Daniela Amodei, and had become one of the most aggressively pursued AI companies in the industry.

Still, leading the Series D at that scale required more than confidence in the company. It required creative capital structuring.

Anthropic’s Valuation Surge After Series D

The 2024 Series D quadrupled Anthropic’s valuation to $18.4 billion. That single round transformed the company’s standing in the market and validated Menlo’s earlier, pre-product entry point. Menlo subsequently participated in Anthropic’s Series E and F rounds, compounding the exposure.

Menlo’s Strategic $750 Million Investment via SPV

Raising $750 million for a single deal during a VC winter required unconventional mechanics. Menlo structured roughly $500 million of the total investment through a special purpose vehicle — a pooled entity created specifically for the Anthropic transaction. The remaining $250 million came from Menlo’s own fund and contributions from firm insiders, according to Forbes reporting at the time.

The SPV approach let Menlo effectively punch above its weight, aggregating capital from multiple sources into a single, authoritative position at the table. It was an aggressive move for the market conditions, and it worked.

What followed that deal is now a different kind of problem. AI-focused SPVs have proliferated to the point where Anthropic itself issued a formal warning, calling all unauthorized SPVs and secondary market claims to sell its stock “scams.” The authorized 2024 Menlo deal was, by that measure, an early example that others have tried to imitate without the underlying access.

Anthology Fund: Menlo and Anthropic’s Startup Investment Vehicle

The Anthropic relationship didn’t stop at the Series D. In 2024, Menlo and Anthropic jointly launched the Anthology fund, initially sized at $100 million. The fund’s mandate was to back early-stage startups building on or alongside Anthropic’s technology, offering portfolio companies more than just capital — including access to Anthropic leadership and credits for Claude.

Since launch, Anthology has grown substantially. It has deployed approximately $250 million and backed more than 60 companies, according to a source with knowledge of the fund. It has already generated returns: Graphite was acquired by Cursor and Astrix Security was acquired by Cisco, two early exits that validate the thesis.

The broader Menlo portfolio now reflects a firm that has used the Anthropic relationship as a scout network into AI startup categories. Companies including OpenRouter, Higgsfield, Legora, Lovable, and OpenEvidence sit alongside Anthropic in the portfolio, giving Menlo a wide view of where the AI stack is developing — from model infrastructure to application-layer tools.

What the $3 billion raise ultimately signals is that limited partners have bought into the entire architecture: not just the Anthropic stake, but the Anthology access layer and the broader AI portfolio that Menlo has assembled around it. The firm turned one conviction bet into a fundraising thesis, and the thesis held. Whether the next fund cycle requires Menlo to find another Anthropic — or whether the firm can build on what it already owns — is the question now sitting beneath the record headline.
