Recent observational data from NSIDC and Copernicus show Arctic sea ice extent declining at a near-average rate through August 2026, with the monthly average at 5.56 million square kilometers—seventh lowest on record—and daily values tracking toward a September minimum near 4.4–4.5 million square kilometers. Persistent warmth over Siberia and the Canadian Archipelago contrasted with cooler high-latitude conditions, while reduced storm activity limited rapid melt acceleration compared to extreme years like 2012. Long-term thinning from greenhouse forcing keeps the ice vulnerable, yet the post-2007 plateau in minima reflects stabilizing weather influences and thicker residual ice in the central basin. Traders’ tight clustering around the 4.2–4.6 million square kilometer bins reflects this balance, with resolution hinging on National Snow and Ice Data Center daily readings through mid-September and any late-season wind or temperature shifts that could nudge the final low.

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.
