Anthropic’s S-1 filing reveals key details for Amazon investors

Anthropic filed a draft S-1 registration statement with the SEC on June 1, 2026, confirming its plans for an initial public offering, with Amazon's stake in the company valued at $190.4 billion as of Q2 2026, up from $74.2 billion in Q1. The filing follows a $65 billion Series H round that valued Anthropic at $965 billion post-money, and Amazon has committed up to $33 billion in total funding. If priced near its private valuation, the IPO would rank among the largest in history, with Anthropic structured as a Delaware public benefit corporation with a Long-Term Benefit Trust to safeguard its AI safety mission.

Via arabianbusiness.com Anthropic’s S-1 filing reveals key details for Amazon investors 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.
