Traders are assigning a 36% implied probability to an Arctic sea ice minimum extent below 4 million square kilometers this September, driven by rapid melt in the Beaufort, Chukchi, and East Siberian Seas amid July's second-warmest Arctic temperatures on record. NSIDC reports current extent at 5.58 million sq km as of early August—below the 1981-2010 average but 790,000 sq km above 2012's pace—while PIOMAS models forecast 4.33 million sq km and CMIP6 ensembles average 4.5 million sq km. Neutral ENSO conditions favor below-average minima, clustering trader odds in the 4.0-4.8 million sq km bins, though thicker central ice buffers extreme lows.

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.
