Anthropic files Nasdaq S-1 as ANT after $80.7 billion first-half loss
October 27: CyberScoop reports Commerce limits on Mythos 5 and Fable 5 and an FTC demand; Latent Space adds cloud-partner revenue share, cash, and disputed burn totals.
Anthropic’s public S-1 seeks a Nasdaq listing as ANT; price and size remain undisclosed after an $80.7 billion first-half net loss.
Anthropic publicly filed an S-1 on Monday to list on Nasdaq under ANT after a confidential June filing, and says it aims to list before OpenAI. SecurityWeek says a debut is planned next month; price and size are undisclosed, while reports it cites put a possible valuation at $1.5 trillion or $2 trillion after a $965 billion private valuation. First-half 2026 revenue was $16.3 billion, versus $1.2 billion a year earlier. The net loss was $80.7 billion: The Register attributes $72.4 billion to a valuation accounting adjustment, SecurityWeek calls that amount a one-time charge, and Latent Space says non-cash charges totaled $81.1 billion. The filing warns of model misuse, blackmail-like or self-preserving behavior, and possible catastrophic harm from future systems, not current models, according to Ars Technica.
