Will Super Typhoon Dolphin hit Japan?

Platform comparison

Market context

Super Typhoon Dolphin has already been tracked over Japanese territory in the far south, and the market now hinges on whether its circulation crosses the coastline again before the settlement deadline. The present 99% crowd price is consistent with the storm’s long-running west-northwest track and repeated guidance pointing towards the Ryukyu chain, especially Okinawa, rather than a clean miss to the south. [3][9][12]

That probability looks much like a near-lock once a system has entered Japan’s warning orbit: previous typhoons that moved through the Ogasawara Islands and then towards Okinawa quickly shifted from a broad track question to a location-and-timing question. The key comparison is not whether Dolphin remains powerful, but whether steering ridges and model drift keep nudging the centre across Japanese land again, which is the threshold that matters for resolution. [3][12][15]

The main catalyst traders are leaning on is official forecast-and-position updates, not political events in the usual sense, with the Japan Meteorological Agency’s advisories carrying the most weight for settlement. Recent reporting from Al Jazeera said Dolphin was expected to hit Okinawa and continue affecting the islands through the weekend, while Stars and Stripes noted the Joint Typhoon Warning Center and ensemble guidance still pointed towards Japan’s general direction, leaving the final landfall path as the decisive variable.

UK Frequently Asked Questions

What resolution source is used for elections?

Polymarket defines the source per contract — usually Associated Press (AP Race Call), Reuters or the official electoral commission. The source is stated in contract details before the market opens.

Can prediction markets influence election outcomes?

Markets reflect expectations rather than create them. Studies show public-facing markets can anchor expectations, but don't influence the underlying outcome. Political markets are information, not advocacy.

How fast do political markets react to news?

High-liquidity markets move within seconds to minutes. A Trump tweet on the economy can shift the "Trump 2024" market 2-5 points before mainstream media has written anything.

Are political prediction markets legal in my country?

It varies. They sit in legal gray areas in most jurisdictions. Polymarket is geo-blocked from US/UK/EU; some broker frontends have a different geo footprint. Trade only with capital you can afford to lose, and only if you understand the legal status in your jurisdiction.

Are UK election prediction markets available from the UK?

Yes. Betfair Exchange and Smarkets offer UKGC-regulated UK election markets (seat counts, party share, constituency results). Polymarket also lists UK election contracts with deeper global liquidity. Betfair winnings are typically tax-free for UK individuals; Polymarket profits are subject to HMRC CGT.
