The S&P 500 undergoes quarterly reconstitution on the third Friday of March, June, September, and December. The next rebalance is currently scheduled for March 20, 2026. This market will resolve to "Yes" if S&P Global Inc. announces that the listed company will be added to the S&P 500 index by March 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No." To qualify, the listed ticker must match the announced ticker added to the index. An announcement from S&P will qualify for a "Yes" resolution, regardless of whether the listed company has actually been added to the S&P 500 index by the resolution date. The primary resolution source will be official announcements from S&P Global Inc. (https://www.spglobal.com/en/press/press-release).S&P 500 inclusion for Q1 2026 hinges on the index committee's assessment of candidates meeting key thresholds: market capitalization exceeding approximately $20 billion, positive GAAP earnings in the latest quarter and over the prior four, sufficient trading liquidity measured by ADI, and U.S. domicile. Recent rebalancings, such as December 2024 additions of Apollo Global Management, Workday, and AIG alongside removals of lower performers, underscore the emphasis on profitable growth amid tech sector dominance. Polymarket trader consensus reflects skin-in-the-game bets on high-market-cap firms like Coinbase or Robinhood gaining eligibility through earnings beats and share price appreciation. Watch late-March 2026 announcement for effective April 1 changes, with upcoming Q4 2025 earnings as pivotal catalysts.
