S&P 500 (SPY) closes above … on July 20?

Platform comparison

Market context

The market resolves on whether the SPDR S&P 500 ETF Trust (SPY) closes above a specific threshold on 20 July 2026, with the settlement window ending at 20:00 UTC. SPY closed at $742.09 on that date, a figure confirmed by multiple data providers including Benzinga and Investing.com[1][4]. The current crowd-implied probability of 0% YES suggests the threshold set in the market title exceeds this closing price, rendering the outcome a definitive no based on observed market data.

Historically, SPY has traded within a 52-week range of $591.89 to $760.40, with recent levels hovering near the lower end of its upper band[2]. A 0% probability aligns with comparable cases where the strike price sits significantly above the actual close, particularly when the asset fails to breach key resistance levels during the settlement day. Programmatic traders would typically back-test conditional orders against such historical ranges to identify thresholds where probability collapses to zero, using the 52-week high as a natural ceiling for realistic strike selection.

Key catalysts for traders evaluating similar markets include the Federal Reserve’s interest rate schedule and quarterly earnings releases from major S&P 500 constituents, which drive intraday volatility. Recent market commentary highlights that macroeconomic data, particularly inflation reports and employment figures, often dictate SPY’s direction in the weeks leading to settlement[3]. A power-user would automate monitoring of these dependencies via API feeds, setting conditional triggers to adjust position sizing or exit strategies when volatility spikes around scheduled announcements.
