S&P 500 (SPY) closes above … on July 27?

Platform comparison

Market context

The S&P 500 will close on 27 July 2026 at a specific price level; the market is pricing a 1% probability that the index finishes above the strike price on that date. This settlement window captures a single trading session roughly eighteen months forward, making the outcome dependent on macroeconomic conditions, earnings reports, and geopolitical events materialising between now and mid-2026.

Historical volatility in single-day S&P 500 moves offers perspective on how extreme a 1% probability truly is. Daily moves exceeding 2% occur roughly 5–10% of the time under normal market conditions; moves beyond 3% are rare but not unprecedented, typically clustering around Federal Reserve decisions, employment reports, or major corporate earnings surprises. The 1% implied probability suggests the strike price sits well beyond two standard deviations from the consensus forecast, placing it in territory that would require either a significant macroeconomic shock or a sustained rally driven by unexpected positive catalysts—earnings beats, dovish policy shifts, or geopolitical de-escalation.

Traders monitoring this contract should track Q2 2026 earnings season (typically concluding by late July), any scheduled Federal Reserve communications, and inflation data releases in the weeks preceding settlement. The US employment report for June 2026, due in early July, historically moves equities sharply and could establish momentum into the final week. Additionally, any material shifts in US–China trade relations or Middle East tensions would influence risk appetite. The strike's extreme positioning means the market is effectively pricing near-zero odds of a surprise catalyst large enough to drive the index substantially higher on that single day.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
