Anthropic generated $16.3 billion in revenue in the first half of 2026, up from $1.1 billion a year earlier, according to a draft IPO prospectus viewed by The Wall Street Journal. The draft also shows roughly $450 billion in cloud compute commitments, per Investing.com's summary of the Journal's report. The largest named deals are with units of Alphabet (NASDAQ: GOOGL), Amazon (NASDAQ: AMZN) and Microsoft (NASDAQ: MSFT), all of which report earnings next week.

The prospectus, or S-1, is not public. Alpha Agentic searches of SEC EDGAR, most recently at 4:37 p.m. ET on Oct. 20, found no S-1 from Anthropic. The company has confirmed only that it confidentially submitted a draft S-1 on June 1.

What the draft shows, per the WSJ

Revenue: $16.3 billion in the first half, versus $1.1 billion a year earlier.

Compute spending: Nearly $9 billion on computing capacity and infrastructure in the first six months, more than the $7.3 billion it spent in all of 2025.

Losses: A first-half net loss of $80.7 billion, of which $72 billion came from non-cash accounting adjustments tied to convertible notes and financing instruments.

Customers: About 20% of first-half revenue came from two customers.

What it means for the hyperscalers

The Journal's account describes the cloud deals as noncancelable obligations over the next decade. Three providers are named: Google Cloud at $111 billion, Amazon Web Services at $110 billion and Microsoft at $31 billion.

By Alpha Agentic's math, those three total $252 billion. Per the Journal's account, Anthropic could potentially spend $750 billion in the coming years on more computing capacity, including deals still under negotiation.

The timing is tight. Alphabet and Microsoft report on Oct. 28, and Amazon follows on Oct. 29.

Beyond the hyperscalers

The draft says Anthropic sought more capacity than the hyperscalers were willing to supply, pushing it toward third-party datacenter developments, per the Journal's account.

That shift is already visible. In November 2025, Anthropic announced a $50 billion investment in U.S. datacenters built with Fluidstack in Texas and New York, with sites coming online throughout 2026. An earlier version of the confidential prospectus, seen by Reuters in September, described a move from a cloud-only model toward dedicated datacenters and directly leased chips. It also listed about $161.2 billion in equipment lease obligations related to Broadcom (NASDAQ: AVGO).

Reuters reported on Sept. 28 that the IPO could value Anthropic at more than $2 trillion. Anthropic is private, and no ticker or listing venue has been officially confirmed.

The Alpha Take

If the WSJ's figures carry into the public filing, the $252 billion we tally across three named deals sits with cloud providers that all report next week, which could make Anthropic a recurring topic on those calls. The same draft shows an $80.7 billion first-half loss, about 20% of revenue from two customers and a turn to third-party datacenters after the hyperscalers would not supply all it sought. Until the S-1 posts, the Journal's account and the hyperscalers' own commentary are the main public reads on how firm that demand is.

What to Watch

Oct. 28: Alphabet and Microsoft results. Watch for comments on cloud backlog and large AI customers.

Oct. 29: Amazon results, including AWS.

Fluidstack sites: Progress on the Texas and New York builds.

The public S-1: We'll cover it in full when it posts on EDGAR. Key checks: whether the $450 billion and $750 billion figures hold, customer concentration, and any ticker or listing venue.
