Trader consensus on Polymarket tilts toward a September 2024 Arctic sea ice minimum of 4.4-4.6 million square kilometers (32% implied probability), driven by NSIDC observations showing current mid-August extent at 5.1 million sq km—12% below the 1981-2010 average but tracking historical norms for this stage. Differentiating lower bins like <4 million sq km (25%) are risks from persistent high-pressure ridges over the Beaufort Sea enhancing solar-driven melt and open-water feedbacks, as seen in accelerated regional losses. Higher outcomes hinge on potential cyclones compacting thin ice or cooler air outbreaks; SIPN model medians cluster near 4.5 million sq km, but late-season weather volatility keeps odds tight amid elevated ocean heat content.

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.
