**Arctic sea ice extent this summer remains on track for a minimum near or slightly below recent averages, with trader consensus centering on the 4.4–4.6 million square kilometer bin.** As of mid-August 2026, daily extent stood around 6–7 million km² (roughly 9th–12th lowest in the satellite record depending on the dataset), following a typical seasonal decline interrupted by a notable slowdown from late July into early August. This pause, unusual on an Arctic-wide scale, stemmed from regional weather patterns that temporarily limited melt in key areas while increased ice export through Fram Strait affected the Greenland Sea. Primary drivers include persistent long-term thinning from Arctic amplification, with particularly low ice concentrations along the Atlantic margin (Barents, Kara, and Greenland Seas) contrasting with relatively resilient ice in the Chukchi and Beaufort Seas earlier in the season. Official outlooks from the Met Office and others indicate the September minimum will very likely fall within the post-2007 range of roughly 4.0–5.5 million km², heavily modulated by unpredictable summer weather, melt rates, and atmospheric circulation. Recent statistical projections anchored to early-August conditions point to intermediate values similar to 2024–2025 (around 4.5–4.6 million km²) as more probable than extremes. Key upcoming influences include August–September weather model runs and daily NSIDC/JAXA monitoring, which will refine the trajectory toward the annual minimum.

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.
