“Will Super Typhoon Dolphin hit China?” is a politics prediction market on Polymarket with two tradeable outcomes, Yes and No. The Yes price is the market's implied probability that the question resolves Yes. Quotes can change as orders are updated or filled; a quoted price does not guarantee an available fill at that price.
This market resolved Yes on 9 Aug 2026. $220.16K traded over its life. The price history, the holders still on the books and the trade tape below are kept as the record of how the crowd priced the question while it was open.
Vultax observes this market from Polymarket's public order book and data API and keeps its own record: 10 daily price points from Jul 31, 2026 UTC to Aug 9, 2026 UTC (Yes between 54.5% and 99.4%); 46 wallets still holding shares after settlement, the largest ten holding 76.3% of the loaded shares; 500 recent public fills from 220 wallets. Each figure carries its observation time; nothing here is a return forecast.
This market resolves "Yes" if the center of Super Typhoon Dolphin's circulation physically crosses the coastline of China on or before August 15, 2026. Resolution is determined by the Japan Meteorological Agency's (JMA) position advisories placing the storm over Chinese land (https://www.jma.go.jp/bosai/map.html#contents=typhoon&lang=en), or by credible international news reporting confirming the storm hitting Chinese territory. For the purposes of this market, "China" refers to all territory under the administration of the People's Republic of China, including Special Administrative Regions (Hong Kong / Macau) and excluding Taiwan. The system's classification is determined by the single JMA advisory in effect immediately prior to the observed crossing. Once that advisory fixes classification at the time of impact, no subsequent real-time advisory, reclassification, or post-season best-track reanalysis may retroactively change the outcome. JMA position advisories are the primary resolution source. If a JMA advisory plots the center on Chinese land, the market resolves "Yes" 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 resolves "Yes." 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. In all cases, the classification is taken from the most recently issued JMA advisory prior to the confirmed crossing time. This is a purely geographic criterion: the storm's center must pass over Chinese land. The most recently issued JMA advisory prior to the crossing must classify Dolphin as a tropical cyclone (tropical depression or higher). If that advisory classifies the system as extratropical, dissipated, or absorbed, the crossing does not count and the market will resolve to "No." This market resolves "No" if Dolphin has been declared extratropical, dissipated, or absorbed on or before August 15 without having made landfall on Chinese territory, or if no landfall has physically occurred by the close of August 15, 2026.

The Yes price read as a chance. A share at 21.5¢ implies 21.5%, but fees, available depth and who participates can affect that price. A market price is not a calibrated forecast or a verdict.
Dollar value of shares that changed hands in the last 24 hours. High volume means the price is being tested by real money; low volume means a few trades can move it.
Reported dollars resting in the order book. The available size on your side, at the prices you would accept, determines what can fill. A large total alone does not guarantee an execution near the quoted price.
The gap between the best bid and the best ask. A tight spread makes entry and exit cheap; a wide spread is a cost paid on every round trip.
The wallets holding the most shares on each side, and how much of the loaded sample the largest ten control. Concentration shows whether a market is a crowd or a handful of large positions.
The public fills, newest first: which wallet bought or sold which outcome, at what price, and when. It is the market's own diary, and every wallet on it links to a trader profile.
Observed closes of the Yes price over the market's life. The range shows how sure or split the crowd has been; the move shows which way it has been changing its mind.
Trading stops at the close time. The outcome is then settled by the resolution source named in the rules. A closed market is not resolved until the venue reports it, so the two states are shown separately.
