Menlo Ventures, an early investor in Anthropic, raises $3 billion for additional technology investments, marking its largest-ever fundraise as it observes its 50th anniversary. The funding announcement comes as the venture firm reflects on its 2024 decision to back Anthropic PBC, which at the time was described as an underdog compared with OpenAI’s ChatGPT and had not yet achieved comparable mainstream adoption or meaningful revenue. According to reporting, Menlo previously committed about $750 million tied to its move toward Anthropic, and in 2024 it also raised about $500 million to support that investment strategy. The firm positions the new capital as support for further AI startup opportunities. Coverage from multiple outlets describes the raise as Menlo’s biggest to date and links it directly to the outcome of its earlier bet on Anthropic. Across sources, the central points remain consistent: the $3 billion total, the largest-ever nature of the raise, Menlo’s 50-year milestone, and the role its Anthropic investment plays in the firm’s current momentum.
