Anthropic has made its Form S-1 public, setting up a Nasdaq listing under the ticker ANT. A draft had been filed confidentially back in June. The share count and price are still blank, and Engadget expects the stock to debut in mid-November.

The figures are large. Revenue for the first half of 2026 came to about $16.3bn, against $1.16bn a year earlier and well above the $4.59bn booked across all of 2025. The net loss was $80.7bn, up from $13bn, yet roughly $72.4bn of that is largely noncash adjustments on convertible debt and similar instruments, and the operating loss narrowed to $693m from $2.1bn.

Compute and infrastructure spending reached nearly $9bn, up from $2.3bn, while second-quarter revenue rose 1,368% on the year against a 300% rise in compute costs. By 30 June the company had raised $141.1bn in total. More than 11,900 customers have each paid at least $100,000 in the past year. Amazon holds $6.2bn of convertible debt and agreed to provide up to $15bn in three tranches, and seven co-founders, among them Dario Amodei and Daniela Amodei, keep 50.1% of voting power.
About Anthropic
Anthropic had already been a heavily funded company well before it filed. In late May 2026 it raised $65bn in a Series H at a $965bn post-money valuation, led by Altimeter, Dragoneer, Greenoaks and Sequoia, a figure that put it ahead of OpenAI's own valuation at the time.
The round beat the $30bn Anthropic had set as its target, and the chipmakers Micron, Samsung and SK Hynix took part with sums that were not disclosed. In June 2026 the company filed a draft S-1 with the SEC, which was not public, so the filing now on view follows that earlier confidential step.

The filing groups AI risk into four kinds: misuse, loss of control, authoritarian abuse and economic disruption, and says a frontier model beyond top human experts could be widely available within a few years. On valuation the outlets differ: Engadget says around $2tn, while Reuters, as relayed by SiliconANGLE, says $1.5tn, down from $2tn. OpenAI is expected to list in 2027.
