Anthropic's run rate clears $80B, but its IPO is losing steam

Anthropic's revenue machine keeps humming. The Claude maker's annualized revenue run rate blew past $80 billion in October, a figure most public companies never touch in a full year of actual sales, according to Crypto Briefing.

The catch: the same update says Anthropic's IPO raise could shrink and the listing itself might slide. Record growth on one side, a cooling debut on the other. An earlier estimate had put the run rate around $65 billion by late July 2026, so crossing $80 billion a few months later marks another sharp leg up.

The filings back it up. Anthropic's S-1 went public on October 26, 2026, with an amendment following on November 2. First-half 2026 revenue landed at $16.3 billion, up from $1.16 billion a year earlier — growth north of 1,300%. Q3 2026 revenue is reported between $16.8 billion and $17 billion, meaning one quarter now outearns the entire first half.

Profit is messier. Anthropic booked its first operating profit in Q2 2026 at $974 million, but also swallowed a net loss of $80.7 billion for H1 2026, mostly non-cash charges tied to convertible notes. The company filed confidentially for its IPO in June 2026 and plans to list on Nasdaq under the ticker ANT.

Timing and price are both fluid. The debut could come as soon as mid-November 2026, after the US midterm elections, though the latest update says a delay is possible. Early speculation floated $2 trillion for the valuation; that's reportedly been trimmed, with the new figure landing near $1.5 trillion as investors get twitchy about tech selloffs and geopolitics. Still, that sits well above Anthropic's $965 billion private valuation from May 2026.

Then there's the bill. Anthropic has committed nearly $895 billion to infrastructure deals, mainly with Amazon, Google and Microsoft — long-term, pre-booked access to the data centers and chips that train and run Claude. That dwarfs even its rosiest revenue forecasts. Growth is also moderating, and analysts have cut full-year projections to $70 billion–$100 billion, down from earlier hopes above $100 billion, with rising rates and AI governance debates adding noise. For investors, three questions loom: does the run rate hold, can the market stomach that compute tab against slowing growth, and does the offering price cleanly — or slip.
