Will Reddit be added to the S&P 500 in Q2 2026?
Prediction markets currently give a 11% probability that Will Reddit be added to the S&P 500 in Q2 2026?. This contract trades at 11¢ on Kalshi, closing July 1, 2026. Reddit's S&P 500 inclusion odds have collapsed 39% over the past week (from 18¢ to 11¢), now pricing in just a 12% probability despite the contract's extreme 3906% implied yield on the Yes side—a classic sign of illiquid, low-conviction pricing with only $631 open interest and zero 24-hour volume.
Analysis
Reddit's S&P 500 inclusion odds have collapsed 39% over the past week (from 18¢ to 11¢), now pricing in just a 12% probability despite the contract's extreme 3906% implied yield on the Yes side—a classic sign of illiquid, low-conviction pricing with only $631 open interest and zero 24-hour volume. The 13¢ bid-ask spread and elevated Cliff Risk Index of 8 suggest minimal market depth, making the astronomical yield figures unreliable for actual trading. With 76 days to expiry and Reddit's recent IPO still establishing its market presence, the market appears to be pricing in low near-term inclusion odds, though the sharp recent selloff warrants monitoring for whether this reflects new fundamental information or simply thin liquidity dynamics.
Resolution rules
If Reddit is announced to be or is officially added to S&P 500 during April 1, 2026 to June 30, 2026, then the market resolves to Yes.
