Polymarket prices $800B at 83% confidence and $1T at 76%, signaling that bettors expect the IPO to clear both thresholds with high probability—the market's base case sits near or above $1T despite management's stated 2027 timeline and current $852B private valuation. Revenue acceleration to a $40B+ annualized run rate and recent analyst forecasts modeling $1.06–$1.20T opening caps are driving the bullish pricing, though timing remains uncertain with conflicting signals: CFO Friar told staff an IPO will come "in 2027 or sooner," while some August reporting suggests a September prospectus filing.
