According to data from Polymarket, the only prediction platform currently tracking this event, traders see no chance that Stripe's market cap will fall below $80 billion at the close of its first trading day. The contract, which has attracted $88,000 in volume, reflects a consensus that the payments giant will command a valuation well above that threshold. No other platforms—Kalshi or Manifold—have listed contracts on this specific outcome, limiting cross-platform comparison but underscoring the market's confidence. Stripe, which has been privately valued at over $50 billion in recent funding rounds, is widely expected to pursue a public listing in the coming years, with many analysts projecting a valuation exceeding $100 billion. The 0% probability on Polymarket suggests that traders view an $80 billion floor as a virtual certainty, though the lack of external news or competing markets leaves room for potential shifts as the IPO date approaches.
