Analysis

This contract pays off if the S&P 500 closes between 6000 and 6199.99 on December 31, 2026, implying a 14% probability traders assign to that outcome. The market is currently pricing in significantly higher year-end levels, with the modal outcomes clustering around 6600-6800 and substantial probability mass extending toward 7000-7200. A 14% probability for the 6000-6199 range reflects trader expectations that the index would need to either stagnate or decline from current levels over the next five months. Resolution depends entirely on the S&P 500's price at market close on December 31, 2026. Key drivers include corporate earnings trajectories, Federal Reserve policy decisions through year-end, and macroeconomic data releases that shape rate expectations. Any significant recession, market correction, or shift in Fed policy would compress valuations and increase the likelihood of this lower band outcome.

  • Current S&P 500 level relative to 6000-6199 range: higher price levels reduce the probability this band is reached at year-end
  • Implied market expectations from competing contracts: 4% probability assigned to 6600-6799 band suggests upside bias, making lower bands less likely
  • Fed rate path through 2026: higher-for-longer policy or accelerating hikes would increase recession risk and lower equity valuations
  • Corporate earnings growth trajectory: slowing or negative revisions would pressure multiples and favor lower year-end levels
  • Market volatility and drawdown magnitude: a severe 15-20% correction from current levels would materially increase this outcome's probability

How we compute these odds

SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.

For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.

Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
