Current observational data place 2026 Arctic sea ice extent near 7 million km² in mid-August, ninth-lowest on record, with pronounced regional contrasts: exceptionally low coverage along the Atlantic margin in the Barents, Kara, and Greenland Seas, contrasted by slower retreat and temporary stabilization in the Pacific sector's Chukchi and Beaufort Seas. This mid-summer slowdown in overall extent loss, combined with variable August weather patterns such as cyclone activity and temperature anomalies, drives trader consensus toward the closely matched 4.4–4.8 million km² bins as the September minimum. Differentiation among bins hinges on late-season melt rates, ice drift through Fram Strait, and storm-driven compaction or dispersion, all of which introduce substantial uncertainty given the short remaining window to the annual minimum.

This market will resolve according to the minimum Arctic sea ice extent for all days between August 1, 2026 and October 1, 2026, as published by the National Snow and Ice Data Center.
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.
