This market tracks whether Atlanta's daily high temperature on May 2, 2026 will reach or exceed 78°F. The 1% YES odds represent extremely strong trader conviction that the day will remain cooler than that threshold. For context, early May in Atlanta typically sees highs in the mid-70s to low 80s, making 78°F just above seasonal normal for this date. The exceptionally low odds suggest traders believe a cool weather pattern or frontal system is pushing through the Southeast, keeping temperatures suppressed despite it being late spring. Resolution depends on the National Weather Service's official temperature reading from the primary Atlanta weather station. The odds trajectory has likely remained relatively stable, given this is a fixed daily temperature forecast with high inherent certainty—weather patterns just 24 hours out have relatively small confidence intervals for major metropolitan areas. Traders with strong conviction based on monitoring extended forecast models showing persistent cool conditions and stable atmospheric patterns are pricing in this extremely low probability of reaching 78°F or higher.
Deep dive — what moves this market
Atlanta's May 2 temperature market exists within the context of well-understood seasonal climate patterns for the Southeast. Late spring weather in Atlanta is characterized by transitional conditions where tropical moisture and warm air masses can rapidly build from the Gulf, but equally, cool continental air masses occasionally penetrate southward behind strong weather systems. The current 1% YES odds reflect an unusual situation where traders have near-total consensus that temperatures will not reach 78°F—a temperature that sits only modestly above historical May 2 average highs of around 75-76°F. This suggests more than just typical spring weather; it indicates a well-defined cool air mass or persistent cloud cover expected to suppress the afternoon high. Factors pushing toward a higher temperature (YES outcome) would include clear skies and strong solar heating, dry air improving daytime warmth, southerly wind patterns advecting warm Gulf air northward, or any delay in a cool front's arrival into the Atlanta area. Historical May 2 data shows temperatures reaching 78°F or higher roughly 40-50% of the time, making it entirely plausible under normal conditions. A northward-moving warm air mass or an unusually strong spring high-pressure system could easily push Atlanta into the upper 70s. Conversely, factors supporting the NO outcome include an active frontal system bringing cooler Canadian air, persistent cloud cover from a low-pressure system limiting solar heating, continued northeasterly or northwesterly flow delivering cool air, or an abnormally strong upper-level trough creating sustained suppression. The 1% odds pricing suggests traders see very high confidence in one of these cooler scenarios—perhaps a well-forecast spring cool front scheduled to move through late May 1 or early May 2, or a slow-moving low-pressure system keeping cloud cover and cooler air in place. The near-zero odds on YES indicate traders are pricing in near-certainty of a cool day, something unusual for early May in Atlanta where warm days are climatologically more common than cool ones. This kind of extreme odds compression typically reflects specific, high-confidence forecast model guidance or recent observations (such as an actual front now in motion with clear timing) rather than seasonal climatology alone.

How does this market resolve?
Market resolves based on the National Weather Service's official highest temperature reading for Atlanta on May 2, 2026. YES resolves if the high reaches 78°F or greater; NO resolves if it stays below 78°F.
Prediction markets aggregate trader expectations into real-time probability estimates. On Polymarket Trade, every market question resolves YES or NO based on a specific event outcome; traders buy shares of the side they believe will resolve positively.
