Anthropic Files S-1 for November IPO, Revealing $80.7B Net Loss

Artificial intelligence firm Anthropic filed its Form S-1 registration statement with the US Securities and Exchange Commission on Oct. 26, targeting a public listing in November ¹. The initial public offering prospectus revealed that Anthropic generated $16.3 billion in revenue during the first half of 2026, alongside a net loss of $80.7 billion over the same interval ¹. The company has not yet published its proposed share count or an initial price range ¹.

Equities tied to the semiconductor supply chain gained during premarket trading following the submission ¹. Shares of Nvidia rose 1.4%, Broadcom gained 1.5%, and Micron advanced 2.3% ¹. Fox Business reporter Liz Claman indicated that the offering remains scheduled to price on Nov. 19 or Nov. 20 ¹. Meanwhile, Financial Times reporting cited investor expectations of a public market valuation between $1.5 trillion and $1.75 trillion, compared to earlier suggestions of a possible $2 trillion valuation seeking to raise up to $100 million ¹.

Crypto Pre-IPO Markets React

Traders on decentralized derivatives platform Hyperliquid responded to the regulatory disclosure via pre-listing contracts tracking Anthropic's expected equity price under the ticker ANTH ¹. The ANTH instrument briefly climbed to roughly $1,980 at 9 a.m. ET around the time of the filing before declining about 6% to $1,857 within minutes ¹. The derivative stabilized near $1,875 shortly after 12:05 UTC, recording approximately $12 million in 24-hour trading volume and a 1.8% daily gain ¹.

The public market filing arrives as broader digital asset markets remain subdued, with $BTC trading at $79,602 and $ETH at $2,305 at the time of writing. While traditional financial markets await the final terms of the tech listing, decentralized perpetual platforms continue to serve as real-time pricing venues for major institutional IPO events ¹.
