Record-low Arctic sea ice maximum extent reached in mid-March 2026 at 14.29 million square kilometers, statistically tied with 2025 for the smallest winter peak in the 48-year satellite record, has positioned traders to favor outcomes below 4 million square kilometers for the September minimum. Persistent record-low extents through April and early May, driven by warmer-than-average ocean and air temperatures, thinner first-year ice, and an emerging El Niño pattern, accelerate melt potential under the long-term 12 percent per decade decline observed since 1979. NSIDC and NASA data confirm the ice pack entered the melt season with reduced volume and extent, increasing the likelihood of significant summer losses if atmospheric patterns favor rapid retreat. Traders monitor upcoming NSIDC updates and model runs for refinements to these probabilities through peak melt season.

This market will remain open until data has been published for October 1, 2026, at which point it will resolve immediately. Any revisions to sea ice extent recorded after data is published for October 1, 2026 will not be considered.
The resolution source for this market measures temperatures to thousands of square kilometers (e.g. 4.255 million sq km). Thus, this is the level of precision that will be used when resolving the market.
The resolution source for this market will be information from the National Snow and Ice Data Center, specifically the minimum value recorded for any day between August 1, 2026 and October 1, 2026 in the “NH-Daily-Extent” tab of the “Sea Ice Index Daily Extent” data set, available at https://nsidc.org/sea-ice-today/sea-ice-tools. If this resolution source becomes unavailable, another resolution source will be chosen.
