Amazon's $33 billion bet on the Claude maker has ballooned into a $190 billion stake as Anthropic eyes one of the largest IPOs ever
Anthropic quietly filed a draft S-1 registration statement with the SEC on June 1, making official what the AI industry had been whispering about for months: the maker of Claude is heading for the public markets. For Amazon, which has poured up to $33 billion into the company, this filing transforms what was already a monster bet into something that could meaningfully reshape the retail giant’s balance sheet.
The confidential filing doesn’t include share count, pricing, or a timeline for listing. Anthropic says those details will depend on market conditions.
The numbers behind the filing #
Just days before the S-1 hit the SEC’s desk, Anthropic closed a $65 billion Series H funding round. That round valued the company at $965 billion post-money, placing it in the same atmospheric tier as the world’s most valuable public companies, except it isn’t public yet.
Anthropic’s annualized revenue run rate sat at roughly $47 billion as of May 2026.
Amazon’s financial exposure here is enormous and increasingly complicated. The tech conglomerate has committed a total of $33 billion to Anthropic, structured across multiple tranches: $8 billion deployed before April 2026, another $5 billion in immediate funding, and milestone-based investments that could reach an additional $20 billion. In return, Anthropic has pledged to spend over $100 billion on Amazon Web Services compute and infrastructure over the next decade.
Amazon’s stake has nearly tripled in value #
By the end of Q2 2026, Amazon’s stake in Anthropic was valued at $190.4 billion. At the close of Q1, that same stake was worth $74.2 billion. In the span of a single quarter, the position appreciated by more than $116 billion.
Amazon’s total investment of $33 billion has generated a paper gain of roughly $157 billion at current valuations, a return of nearly 6x before Anthropic has even priced its IPO.
Governance structure sets Anthropic apart #
Anthropic isn’t filing as a typical corporation. The company is structured as a Delaware public benefit corporation, which legally obligates its board to balance shareholder returns with broader societal considerations. It has also established a Long-Term Benefit Trust with majority rights in board elections, a governance mechanism designed to prevent the kind of hostile takeover or activist-driven pivots that could compromise the company’s stated AI safety mission.
This dual structure means public shareholders will have less control over board composition than they would at a traditional C-corp.
Google also holds a significant position in Anthropic, making the company’s cap table a who’s-who of Big Tech cloud providers competing against each other while simultaneously bankrolling the same AI lab.
What this means going forward #
If Anthropic prices its IPO anywhere near its $965 billion private valuation, it would rank among the largest public offerings in history. A $965 billion valuation implies roughly a 20x multiple on annualized revenue. Anthropic has the cash reserves from its $65 billion raise to wait for favorable market conditions, which is precisely why the filing language leaves timing deliberately vague.
