Anthropic Raises $65bn, Surpasses OpenAI as Founders Become Billionaires

Anthropic, the artificial intelligence company behind the Claude assistant, has completed a record-shattering funding round that propels its market valuation to an estimated $965 billion, making it the world's most valuable technology startup and minting seven new billionaires. The $65 billion capital injection, confirmed this week, exceeds the entire annual GDP of many developed nations and cements the firm's position at the pinnacle of Silicon Valley's AI boom. The round triples the company's previous $380 billion valuation from February and eclipses the $852 billion to $730 billion range recently assigned to its chief rival, OpenAI, the creator of ChatGPT.

The eye-watering sums have translated into staggering personal wealth for Anthropic's founders, led by siblings Dario and Daniela Amodei. With each owning less than 1 per cent of the company, their individual stakes are now worth approximately $8 billion, according to calculations by Bloomberg's billionaires index. Co-founders Tom Brown, Jack Clark, Jared Kaplan, Sam McCandlish and Christopher Olah also join the ranks of the world's 500 richest people, a concentration of tech wealth unprecedented for a single company in a single day. Viewed from Sydney, where one of the first reports of the founders' new fortunes emerged, the scale underscores how AI equity has become the preeminent engine of modern megafortunes.

Analysts in São Paulo attribute the stratospheric valuation to blistering revenue growth. Pablo Alencar, a partner at Valor Capital, framed the surge as a direct consequence of commercial traction rather than speculative frenzy. "It is precisely this exponential revenue growth that is driving the valuation," he remarked, as Brazilian media highlighted the firm's ascent past OpenAI. Meanwhile, from Washington, the focus has been on strategic infrastructure: the fundraising is earmarked to secure supplies of advanced semiconductors and to dramatically expand cloud-computing capacity across American data centres, positioning Anthropic to meet insatiable enterprise demand for its AI models.

The achievement marks a dramatic reshuffling of the AI hierarchy. Only last year, OpenAI triggered the current generative AI wave with ChatGPT's public launch, establishing a seemingly unassailable lead. Yet Anthropic has surged ahead, its value nearly tripling in a matter of months. While some Spanish-language financial reports cited a lower $30 billion raise, the broader consensus among international financial wires confirms the $65 billion figure, underscoring the breakneck pace at which capital is flowing into the sector. The company's backers, likely a consortium of sovereign wealth funds, venture capital titans, and tech incumbents, are betting that the winner of the AI platform race will command a market measured in the trillions.

The infusion poses profound questions for regulators and competitors. With capital of this magnitude, Anthropic can lock in critical compute infrastructure for years, potentially creating barriers to entry that only a handful of state-backed entities could match. As the company's valuation approaches the symbolic $1 trillion mark, it enters territory once reserved for the giants of the oil and consumer internet eras. The Amodei siblings, both in their thirties, now stand alongside the world's industrial dynasties, their wealth derived not from physical resources but from algorithms—a shift that signals a new chapter in the global economic order.
