Recent atmospheric cooling over the high-latitude Arctic Ocean, driven by persistent low-pressure systems and cloud cover in August, has slowed seasonal melt and positioned the 2026 minimum Arctic sea ice extent near 4.4–4.6 million square kilometers. NSIDC data show August averaged 5.56 million square kilometers, seventh-lowest in the satellite record and well above 2012 levels after early-summer tracking. Long-term decline from Arctic amplification continues at roughly 9–12% per decade, yet preconditioned thin ice and variable weather introduce uncertainty. The National Snow and Ice Data Center is expected to confirm the annual minimum around mid-September based on daily extent observations.

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.
