Anthropic’s October 26 SEC S-1 filing, disclosing first-half 2026 revenue of $16.3 billion (up sharply from $1.2 billion a year earlier) alongside an $80.7 billion net loss and plans for a Nasdaq listing under ticker ANT, serves as the dominant catalyst for current valuation odds. The company’s May 2026 Series H round set the latest official private mark at $965 billion, while investor discussions have tempered IPO expectations toward the $1.5 trillion range from prior $2 trillion targets. With the October 31 resolution deadline hours away and no subsequent private-market update via Nasdaq Private Market pricing reported, trader consensus reflects limited scope for an immediate revaluation. The filing’s emphasis on compute costs and growth sustainability further anchors near-term sentiment ahead of the mid-November IPO window.
