Anthropic has disclosed the scale of its long-term financial obligations for the first time, revealing nearly $900 billion in future commitments in its registration statement for a proposed initial public offering.

The AI company behind the Claude model filed its S-1 registration statement with the U.S. Securities and Exchange Commission (SEC) on October 26, 2026. The S-1 is the disclosure document a company must file before its shares can trade on a U.S. exchange, laying out an issuer's financials and risk factors for public scrutiny for the first time. The filing details future payment obligations covering servers, data centers, buildings, and power, with terms running from one to 20 years. Most of these commitments are largely non-cancelable, meaning payments remain due regardless of how demand for AI capacity evolves.

What the Filing Shows

The headline figure breaks into several layers. The firmest is approximately $417 billion in minimum payments for compute infrastructure, data centers, and leases. On top of that sits an additional $125 billion to $150 billion in projected capacity costs spanning 2028 through 2031 — expected spending rather than locked-in minimums. Broader obligations push the total commitments toward the nearly $900 billion mark.

The counterparty list is drawn from the biggest names in technology. Broadcom accounts for $161 billion of the commitments, Google for $114.5 billion, Amazon for $110 billion, and Microsoft for $45 billion, each spread over various terms. SpaceX/xAI also appears among the company's key partners. The four named commitments alone total well over $400 billion.

That concentration is significant, and the filing flags it directly: Anthropic relies heavily on a small number of providers to keep growing. Commitments with terms this long serve a practical function — reserving compute, data-center space, and power years in advance — and the non-cancelable structure is the counterpart of that reservation.

Anthropic characterizes its approach to locking in these deals as “bold but sane.” The company also acknowledges that its commitments could be viewed within the industry as irresponsibly large.

Revenue Up, Losses Wider

The growth figures are substantial. Anthropic reported revenue of $16.3 billion for the first half of 2026, up from $1.16 billion in the same period a year earlier — a roughly 1,300% year-over-year increase.

The loss column is equally striking. The company posted a net loss of $80.7 billion for the first half of 2026. According to the filing, most of that loss stemmed from non-cash accounting charges — expenses recorded on paper that do not reflect money actually leaving the company's bank account during the period.

The Road to Nasdaq

Anthropic anticipates listing on the Nasdaq under the ticker ANT. Its potential valuation has been estimated at between $1.5 trillion and $2 trillion, supported by heavy investment from major technology companies. A valuation in that range would place Anthropic among the most valuable companies listed on U.S. exchanges. The filing starts that process rather than ending it: registration statements of this kind are typically reviewed and amended, with updated financials added before a final offering price is set.

The structure of the deals creates an unusual web of relationships. Google, Amazon, and Microsoft are at once Anthropic's partners and suppliers while also running competing AI efforts of their own. Broadcom, which represents the largest single commitment on the list, supplies the chip side of the equation. In practice, much of Anthropic's spending flows back to the same companies that back it. This circularity is not unique to Anthropic, but the S-1 puts precise figures on the phenomenon for the first time.

What It Means for Investors and the AI Race

For prospective shareholders, the core question is simple to state and hard to answer: can revenue keep compounding fast enough to cover obligations that stretch up to two decades into the future?

Partner concentration adds another layer of risk. When a handful of suppliers account for the bulk of a company's capacity, their pricing decisions, supply constraints, and strategic priorities become the company's problem as well. The filing itself treats this reliance as a material factor.

Three issues stand out as the IPO approaches. First, whether the valuation range holds up once institutional investors digest the full scope of the obligations. Second, how Anthropic explains the gap between its firm $417 billion in minimum payments and the broader total approaching $900 billion. Third, whether second-half 2026 revenue keeps pace with the trajectory that made the first half so eye-catching.

Anthropic calls its strategy bold but sane. Public markets are about to decide how much weight to give each of those words.
