Hurricane Isaias reprices weather board: Cat 4+ U.S. landfall at 17%

Weather market moves into focus

The market for a Category 4+ U.S. hurricane landfall stood at 17% in a Hurricane Isaias update published by predictionauthority.com on Oct 13, 2026, at 6:39 AM ET.

The outlet’s summary said there had been no significant new headline in the preceding 15 minutes. It therefore led with its freshest weather-market item, switching categories after the previous three editions.

The headline connected Isaias with a repricing of the weather market. However, the supplied material did not include an earlier probability, leaving the size and direction of that change unspecified.

The full source text was unavailable. The headline and summary also did not provide the contract’s resolution criteria or a forecast for Isaias’s landfall location or intensity.

What it means for prediction markets

• The reported level is 17%. That is the headline’s figure for Category 4+ U.S. landfall, not confirmation that Isaias will make landfall at that intensity.
• The move cannot be quantified. Without a prior price, the available material does not establish how much the market repriced.
• Contract scope remains unclear. The supplied text does not establish whether the landfall contract applies specifically to Isaias or covers a broader period.
