Kalshi
This market tracks which storm name will designate the first hurricane to develop in the Central Pacific basin during the 2026 season. On Kalshi, Nolo holds the leading probability at 19.0%, with Ulana at 16.0%. Resolution will be determined by the National Weather Service classification of the first storm meeting hurricane criteria in the Central Pacific between May 15, 2026 and December 1, 2026. Watch for the onset of the Central Pacific hurricane season in mid-May 2026, when atmospheric conditions and sea surface temperatures will begin favoring tropical cyclone development.
The market resolves to Yes for whichever pre-assigned name corresponds to the first storm categorized as a hurricane in the Central Pacific between May 15, 2026 and December 1, 2026. If no hurricane occurs during this period, all outcomes resolve to No. Resolution is based on official National Weather Service naming and classification of tropical cyclones.
The market resolves on Dec 1, 2026. The outcome is determined by which name is officially assigned to the first hurricane that forms in the Central Pacific basin during the 2026 Atlantic hurricane season. Resolution depends on official designation by the National Hurricane Center and the established naming list for that year. Once a tropical cyclone reaches hurricane strength (sustained winds of 74 mph or greater) in the Central Pacific and receives its official name, the corresponding contract resolves to 100 and all other name contracts resolve to zero. The market captures the specific identity of that first named storm.
Sea surface temperatures across the Central Pacific will be a primary driver, as warmer waters increase hurricane formation likelihood and timing. The strength of the El Niño or La Niña pattern influences where and when storms develop, potentially shifting which name emerges first. Early-season tropical activity in adjacent basins can signal broader atmospheric conditions favoring Central Pacific development. Real-time weather models and seasonal outlooks from NOAA will shape trader expectations about storm formation timing and location. Any significant atmospheric pattern shifts or unexpected tropical disturbances in the region could alter probabilities as traders reassess which names face the highest risk of becoming the first hurricane.
