- Sequoia now backs three AI competitors—OpenAI, xAI, and Anthropic—signaling venture firms are abandoning sector exclusivity for the scale of AI opportunity.
Summary
Sequoia Capital is investing in Anthropic for the first time as part of a $25 billion funding round that values the company at $350 billion, more than double its $170 billion valuation from four months ago.
GIC and CO2 are leading the round, each committing $1.5 billion. Microsoft and Nvidia have committed up to $15 billion combined, with venture capital and other investors covering the remaining $10 billion.
Sequoia's entry marks a strategic shift. The firm's predecessor Rolloff, who stepped down in November, had passed on earlier Anthropic funding rounds and argued that venture capital was concentrating too much money into a handful of highly valued startups. Pat Grady and Alfred Lin now co-lead Sequoia, and their decision to back Anthropic breaks with that earlier view.
The move also signals a departure from traditional venture practice. Sequoia has already backed OpenAI and Elon Musk's xAI, both Anthropic competitors. Venture firms typically avoid backing rival startups in the same category, preferring to pick winners in each sector. The scale of the financial opportunity in AI has upended that discipline. Claude's adoption appears to have driven the decision. Users cannot stop using it, forcing investors to get a stake in the company.
