Menlo Ventures has closed a record $3 billion fund, marking the largest capital raise in the firm’s fifty-year history. The commitment was primarily secured through strong demand driven by the firm’s artificial intelligence portfolio, particularly its early and dominant position in Anthropic. Sources indicate that Menlo’s stake in the generative AI company is now valued at approximately $14 billion. The fundraise serves as a direct return on the firm’s decisive $750 million Series D lead in Anthropic during 2024. At a time when global venture capital was still navigating a post-pandemic downturn, Menlo structured the capital commitment through a special purpose vehicle to aggregate external funding, contributing an additional $250 million from its own reserves. The strategy navigated a highly competitive landscape where Anthropic, founded by former OpenAI researchers and backed by a landmark $4 billion commercial agreement with Amazon, saw its valuation quadruple to $18.4 billion. Menlo subsequently participated in Anthropic’s Series E and F rounds, cementing its status as a cornerstone investor. Beyond direct equity stakes, Menlo leveraged the partnership to establish the Anthology fund, a $100 million venture vehicle co-created with Anthropic. The fund has since deployed approximately $250 million across more than sixty early-stage companies. This ecosystem play has already generated measurable returns, including the acquisitions of Graphite by Cursor and Astrix Security by Cisco. Through Anthology, Menlo has integrated direct access to Anthropic’s technical leadership and infrastructure credits, enabling rapid validation of AI-native startups across infrastructure, developer tools, and vertical applications. The successful capital formation follows a broader industry normalization after the venture winter, with institutional capital returning to high-conviction technology bets. Menlo’s broader AI portfolio now includes prominent emerging players such as OpenRouter, Higgsfield, Legora, and Lovable, reflecting a concentrated institutional shift toward generative AI development. The $3 billion vehicle positions the firm to continue leading financing rounds across the artificial intelligence stack, capitalizing on both foundational model advancements and their commercial downstream applications.
