Anthropic’s proposed $2 trillion IPO would turn the Claude maker into the biggest public-market debut ever. But the valuation is racing far ahead of the one number public investors are least willing to take on faith: durable profit.

The company’s momentum has been extraordinary. After saying in May that annualized revenue had passed $47 billion, Anthropic confidentially filed IPO paperwork with the SEC in June. Its investors now expect an October float at $2 trillion or more—more than double the $965 billion valuation attached to its May funding round and above SpaceX’s $1.77 trillion June listing.¹

The bull case rests on enterprise demand. Backers project $100 billion to $120 billion in annualized revenue by the end of 2026, arguing that Claude’s model performance and business-focused sales make it a rare AI winner. One investor framed the upside bluntly: “If Anthropic is growing 800 percent a year, you’d think at the incredibly low end they would trade at 30 times [revenue].”¹

Yet that growth story has been interrupted by real frictions. A temporary Commerce Department ban on Anthropic’s leading models slowed growth in June and rattled customers, while cheaper Chinese alternatives and OpenAI’s lower-priced flagship have sharpened pressure on spending. Ramp data showed Anthropic gaining US business share, but also found companies were “hitting their limit on AI spend” and moving toward cheaper options.¹

The skeptical case is less about whether Anthropic can sell AI than whether it can turn those sales into bottom-line earnings. At typical Nasdaq 100 earnings multiples, a $2 trillion company would need roughly $59 billion to $79 billion in annual profit—an Amazon-scale result. Anthropic may post an operating profit for the first time in the second quarter, but operating profit excludes debt costs and taxes, leaving net income unresolved.²

Investors will also scrutinize its compute bill: whether capacity from Amazon, Google, Broadcom and SpaceX is owned or leased, and how predictable those costs are. As Renaissance Capital’s Avery Marquez put it, “Just seeing the [$2 trillion] number, it’s definitely jolting.”² For Anthropic, the October pitch will be simple; proving it may not be.
