**Recent official observations from the Japan Meteorological Agency (JMA) during Typhoon Dolphin's passage over Okinawa and the Ryukyu Islands around August 7, 2026, form the core driver of the overwhelming 99.5% market-implied probability for "Very Strong Typhoon" at landfall or closest approach in Japan.** JMA reported sustained winds of approximately 155 km/h (10-minute average) and a central pressure near 935 hPa as the large system crossed the region, meeting the agency's criteria for a "very strong typhoon" (typically 44 m/s or higher sustained winds on the JMA scale). This aligns with Joint Typhoon Warning Center estimates of Category 2-equivalent strength and direct impacts including gusts exceeding 150 km/h, power outages, and minor injuries. Model consensus from sources like JTWC and others showed the storm maintaining this intensity through the Japan interaction window after earlier super-typhoon peaks, before expected weakening en route to China landfall. The market's near-certainty reflects skin-in-the-game aggregation of real-time agency data, satellite imagery, and historical analogs of similar western North Pacific systems. Realistic challenges to this positioning remain limited but could include post-event reanalysis revising peak winds below the very strong threshold or disputes over exact "landfall" timing versus closest approach to specific Japanese islands. New forecast updates or official bulletins would be the primary triggers for any shift.

Resolution is determined by the Japan Meteorological Agency's (JMA) position advisories placing the storm over Japanese land (https://www.jma.go.jp/bosai/map.html#contents=typhoon&lang=en), or by credible international news reporting confirming the storm hitting Japanese territory. The applicable advisory is selected as follows: if a JMA advisory plots the center on Japanese land, that advisory's wind speed resolves the market; if no JMA advisory plots the center on land but credible reporting confirms a crossing occurred between discrete advisory fixes, the intensity is taken from the most recently issued JMA advisory prior to the confirmed crossing time. Once the applicable advisory is identified, its intensity fixes the outcome; no subsequent real-time advisory, reclassification, or post-season best-track reanalysis may retroactively change the outcome.
Archival evidence of JMA advisory data is maintained by the Digital Typhoon database (National Institute of Informatics, Japan) at its Typhoon Images and Charts page for Typhoon 202613 (DOLPHIN). In the event of a resolution dispute, the intensity value recorded by Digital Typhoon for the applicable advisory fix shall be treated as conclusive evidence of what JMA reported.
JMA position advisories are the primary resolution source. If a JMA advisory plots the center on Japanese land, the market resolves based on that advisory's wind speed regardless of what other sources say. If no JMA advisory plots the center on land but credible reporting confirms a crossing occurred between discrete advisory fixes, the market still resolves, with intensity taken from the most recently issued JMA advisory prior to the confirmed crossing time. A disagreement exists only when a JMA advisory and credible reporting make contradictory claims about the storm's position at the same point in time; in that case, JMA is the default resolution source. Only the first qualifying landfall on Japanese territory resolves the market; subsequent landfalls are disregarded.
This is a purely geographic criterion: the storm's center must pass over Japanese land, regardless of whether JMA formally designates the event as "landfall" or "passage." The applicable JMA advisory (as selected above) must show maximum sustained winds of 34 knots or higher, classifying Dolphin as a tropical storm or above. If the applicable advisory classifies the system as a tropical depression (below 34 kt), extratropical, dissipated, or absorbed, the crossing does not count and the market resolves to "No Qualifying Landfall."
This market resolves "No Qualifying Landfall" if Dolphin has been declared extratropical, dissipated, or absorbed on or before August 15 without having made landfall on Japanese territory, if the applicable advisory at the time of crossing shows winds below 34 knots, or if no landfall has physically occurred by the close of August 15, 2026.
