Sequoia Capital is reportedly joining a blockbuster funding round for Anthropic, the AI startup behind Claude, according to the Financial Times. It’s a move sure to turn heads in Silicon Valley.
Why? Because venture capital firms have historically avoided backing competing companies in the same sector, preferring to place their bets on a single winner. Yet here’s Sequoia, already invested in both OpenAI and Elon Musk’s xAI, now throwing its weight behind Anthropic, too.
The timing is particularly surprising given what OpenAI CEO Sam Altman said under oath last year. As part of OpenAI’s defense against Musk’s lawsuit, Altman addressed rumors about restrictions in OpenAI’s 2024 funding round. While he denied that OpenAI investors were broadly prohibited from backing rivals, he did acknowledge that investors with ongoing access to OpenAI’s confidential information were told that access would be terminated “if they made non-passive investments in OpenAI’s competitors.” Altman called this “industry standard” protection (which it is) against misuse of competitively-sensitive information.
According to the FT, Sequoia is joining a funding round led by Singapore’s GIC and U.S. investor Coatue, who are each contributing $1.5 billion. Anthropic is aiming to raise $25 billion or more at a $350 billion valuation — more than double its $170 billion valuation from just four months ago. The WSJ and Bloomberg had earlier reported the round at $10 billion. Microsoft and Nvidia have committed up to $15 billion combined, with VCs and other investors said to be contributing another $10 billion or more.
The Sequoia connection with Altman runs deep. When Altman dropped out of Stanford to start Loopt, Sequoia backed him. He later became a “scout” for Sequoia, introducing the firm to Stripe, which became one of the firm’s most valuable portfolio companies. Sequoia’s new co-leader Alfred Lin and Altman also appear comparatively close. Lin has interviewed Altman numerous times at Sequoia events, and when Altman was briefly ousted from OpenAI in November 2023, Lin publicly said he’d eagerly back Altman’s “next world-changing company.”
While Sequoia’s investment in xAI might seem to have already contradicted the traditional VC approach of picking winners, that bet is widely viewed as less about backing an OpenAI competitor and more about deepening the firm’s extensive ties to Elon Musk. Sequoia invested in X when Musk bought Twitter and rebranded it, is an investor in SpaceX and The Boring Company, and is a major backer of Neuralink, Musk’s brain-computer interface company. Longtime Sequoia leader Michael Moritz was even an early investor in Musk’s X.com, which became part of PayPal.
