This market resolves "Yes" if the peak RONI for the 2026–27 El Niño is below +1.5°C. Otherwise, it resolves "No". The peak RONI is the single highest Regional Ocean Niño Index (RONI) value reported by NOAA's Climate Prediction Center (CPC) across the overlapping three-month seasons ASO 2026, SON 2026, OND 2026, NDJ 2026-27, and DJF 2026-27, as reported in official NOAA CPC RONI updates (https://www.cpc.ncep.noaa.gov/products/analysis_monitoring/enso/roni/). The first published RONI value for each listed season is final and governs resolution; no subsequent revision to a season's value will change the outcome once that season's first value has been published. If CPC's RONI dataset is permanently discontinued, other information from NOAA may be used.This market resolves "Yes" if the peak RONI for the 2026–27 El Niño is at least +1.5°C and below +2.0°C.

Otherwise, it resolves "No". This market resolves "Yes" as soon as NOAA publishes a RONI value of +2.5°C or above for any listed season. If no listed season reaches +2.5°C, this market resolves "No" once NOAA has published the RONI value for DJF 2026-27.

The first published RONI value for each listed season is final and governs resolution; no subsequent revision to a season's value will change the outcome once that season's first value has been published. If CPC's RONI dataset is permanently discontinued, other information from NOAA may be used.Recent rapid intensification of equatorial Pacific sea surface temperatures, with weekly Niño 3.4 anomalies reaching +2.6°C and subsurface heat content at record levels, drives trader consensus toward a very strong 2026-27 El Niño. NOAA’s Climate Prediction Center reports a greater than 90% probability of a very strong event this fall and winter, alongside a 69% chance the 3-month peak RONI exceeds +2.5°C—surpassing prior records on the relative index that accounts for background tropical warming. Model ensembles show some divergence in peak timing and magnitude due to evolving atmospheric coupling and potential steering influences, creating the tight spread across the 2.0–2.5+ ranges. Forecasters will release updated CPC outlooks and new model runs in coming weeks that could refine the upper-end probabilities.
