Arctic sea ice traders are pricing a 58% implied probability for the September 2026 minimum extent below 4 million square kilometers, driven primarily by the record-low winter maximum of 14.29 million square kilometers reached on March 15—tying 2025 as the lowest in the 48-year NSIDC satellite record—and persistently low spring extents tracking second-lowest on record through late April. Thin ice cover from anomalously warm air temperatures over the Arctic Ocean, combined with NOAA CPC model consensus for a below-normal September minimum and forecasts of a developing Super El Niño enhancing melt via Pacific warm-air intrusions, underpin this positioning. Upcoming SIPN Sea Ice Outlooks in May and June, plus daily NSIDC updates, will refine model ensembles amid inherent forecast uncertainty from weather patterns.

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.
