Anthropic filed its IPO paperwork with the Securities and Exchange Commission on Monday. The filing covered the company and its Claude AI platform, and moved it closer to a public listing.
The S-1 said revenue in the first half of 2026 was $16.3 billion, up from $1.2 billion in the same period in 2025. It also said net loss was $80.7 billion, and that revenue growth was expected to slow over time.
Anthropic said it spent $8.9 billion on chips and other infrastructure in the first half of the year, against $2.3 billion a year earlier. The company said its shares would trade under the symbol ANT, and the article said reports put the possible size of the offering at as much as $100 billion.
Anthropic's founders, including chief executive Dario Amodei, also told prospective investors to think of the stock as more than a normal purchase. The article said market analysts expected a listing as early as November, while Nigel Green of deVere Group and Lightshed analysts described the flotation as a test of the wider AI market and a source of major downside risk.
