Anthropic’s October 26 public S-1 filing with the SEC has driven trader consensus toward a near-term Nasdaq listing under ticker ANT, with Polymarket-implied probabilities exceeding 85% for November 2026 and 94% for completion by year-end. The filing disclosed first-half 2026 revenue of $16.3 billion—up over 1,300% year-over-year—alongside an $80.7 billion net loss dominated by non-cash convertible note revaluations, improving adjusted operating income, and roughly $500 billion in compute commitments. Expectations for a $1.5–2 trillion valuation at launch have moderated amid broader AI equity volatility and elevated Treasury yields. The planned roadshow and debut, targeted for the week of November 16 ahead of Thanksgiving, represent the key near-term catalyst, with any delay from regulatory review or market conditions able to shift pricing.
