Why did it move?

Structured · 5 factors
  1. 1

    Up 25pp over 24h

    Now 62¢; +0.1pp in the last hour.

  2. 2

    Heavy volume on this book — 23.6× turnover

    $9.0k traded against $381 of visible liquidity. The book is being worked, not just quoted.

  3. 3

    Resolution-risk signal firing

    Market has reached expiry. Watch the UMA dispute window.

  4. 4

    Wide spread — 40.8¢

    Bid-ask spread is wide enough that intraday moves overstate any tradeable edge. Most of the headline pp move would be eaten by spread on a market order.

  5. 5

    Past expiry — awaiting resolution

    Market is past its end date. Any price move now is a settlement / dispute artefact, not new information.

What to track next

  • Verify the resolution source on this page — exchange feed, official release, news consensus — before treating any move as new information.
  • Wait for the UMA proposal to settle (current status: disputed) — price moves now reflect oracle dynamics, not odds.

Verification actions only — never trade recommendations.

Each factor is grounded in a single named metric you can verify on this page — probability, volume, liquidity, signal, resolution state. No predictions, no prose hallucinations.

Market Description

This market will resolve according to the number of geomagnetic storms, solar radiation storms, or radio blackouts with a severity level of 3 or greater which occur between April 19, 2026, 12:00AM ET and April 25, 2026, 11:59PM ET. Otherwise, this market will resolve to "No". A G3 event is a geomagnetic storm with a classification indicating "Strong". An S3 event is a solar radiation storm with a "Strong" classification. An R3 event is a radio blackout event with a classification indicating "Strong". More information on the space weather classification criteria can be found here: https://www.swpc.noaa.gov/noaa-scales-explanation This market will resolve immediately upon the occurrence of a qualifying event. Any later revisions or corrections will not be considered. Only the initial report of an ongoing event with multiple reports will qualify, unless the rating of the event is upgraded to a qualifying level from a non-qualifying level within this market's timeframe. If the reported data falls exactly between two brackets, this market will resolve to the higher range bracket. This market will resolve based on information from the National Oceanic and Atmospheric Administration's Space Weather Prediction Center under the heading marked "Current Space Weather Conditions". (https://www.swpc.noaa.gov/products/alerts-watches-and-warnings#) If the resolution source becomes permanently unavailable, this market will resolve to the lowest bracket.
