Why did it move?

Structured · 4 factors
  • 1

    Up 11pp over 24h

    Now 28¢; flat in the last hour.

  • 2

    Resolution-risk signal firing

    Expires in 25h with open resolution ambiguity.

  • 3

    Wide spread — 13.0¢

    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.

  • 4

    Expiry in 25h

    Market resolves within 72 hours — the move likely reflects information about the resolution event itself rather than longer-horizon repricing. Verify the resolution source.

What to track next

  • Verify the resolution source on this page — exchange feed, official release, news consensus — before treating any move as new information.
  • Set an alert for resolution status changes — expiry is in 25 hours.

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.
