Anthropic files S-1 for Nasdaq listing under ticker "ANT"

Anthropic's public S-1 filing marks the first time the company's financials have entered the public record. The filing puts first-half 2026 revenue at around $16.3 billion, giving outsiders a concrete figure where previously only private estimates circulated. For a company planning to list on Nasdaq under the ticker "ANT," this disclosure is a required step before any shares can trade.

The filing also sets in motion a process that could lead to a listing before Thanksgiving, with a roadshow reportedly starting the week of November 9. However, no share price or offering size has been made official yet, so the actual terms of the offering remain unknown.

For observers who have followed Anthropic's rise, the S-1 offers the first official window into its business performance, shifting the conversation from speculation to reported numbers.
