Anthropic swung to a $567 million operating loss in the third quarter, reversing a $974 million profit from Q2, according to an amended IPO filing reported by CoinDesk. The timing is awkward. The company is weeks away from its planned November IPO.
The numbers
Revenue came in at $17 billion for the quarter. That sounds strong until you look at the growth rate. Quarter-over-quarter growth slowed to 47%, down from 144% in Q2. Price reductions and contractual discounts also shaved roughly $600 million off revenue, partially offsetting growth from higher usage.
The filing pins the operating loss on two main drivers. Anthropic spent $5 billion on computing capacity through costlier short-term commitments instead of cheaper multiyear agreements. It also booked $2 billion in noncash charges tied to its donation-matching program.
Strip out stock-based compensation and charitable contributions and the picture improves. Adjusted operating profit was $2.5 billion, up from $2.2 billion the prior quarter. But adjusted operating margin still slipped to 15% from 19%.
The headline net loss of $23.3 billion is mostly accounting noise. A $21.9 billion charge from revaluing convertible notes and related instruments drove it, the kind of charge that shows up when a company's enterprise valuation keeps climbing. Private markets mark Anthropic up, and the balance sheet takes the hit on paper.
The commitment that matters
The number I keep coming back to is $895.4 billion. That is Anthropic's total purchase and lease commitments, with $69.8 billion due within 12 months of September 30. Against $17 billion in quarterly revenue, that is an enormous pile of future obligations.
The short-term compute buying is the tell. Companies lock in multiyear deals when they are confident about prices and their own trajectory. Buying $5 billion of capacity on short-term commitments at higher prices suggests one of two things: Anthropic could not get the multiyear capacity it wanted, or it is betting compute prices fall and does not want to be stuck holding expensive contracts. Neither reading is comforting heading into an IPO.
My read
The bull case is simple. Revenue is growing, adjusted profit is rising, and the net loss is a valuation artifact. The bear case is also simple. Growth is decelerating fast. Margins are compressing. And the company is signing up for nearly a trillion dollars in commitments while its cost structure depends on compute prices cooperating.
Both can be true at once. That is what makes this filing more worth reading than whatever IPO marketing follows. Whether public market investors price Anthropic on the $2.5 billion adjusted profit or the $895.4 billion in obligations will say a lot about how much slack the AI trade has left.
