Why did it move?

    Liquidity

    Thin liquidity

    Only $1.5k of visible book — small orders can move the line. Treat the probability as a soft estimate.

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: proposed) — 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

Each market will resolve to “Over” if the fight between Tatsuro Taira and Joshua Van at UFC 328: Chimaev vs. Strickland, scheduled for May 9, 2026, lasts beyond the listed round threshold. Each market will resolve to “Under” if the fight between Tatsuro Taira and Joshua Van at UFC 328: Chimaev vs. Strickland, scheduled for May 9, 2026, does not last beyond the listed round threshold. For example: “Over 2.5 Rounds” will resolve “Yes” if the fight continues past the 2:30 mark of Round 3. “Under 2.5 Rounds” will resolve “Yes” if the fight ends before the 2:30 mark of Round 3. If the fight ends exactly at the threshold (e.g., 2:30 of Round 3 for a 2.5 line), it will resolve “50-50.” If the bout is not scored, postponed beyond May 23, 2026, or canceled, all options will resolve “50-50.” The resolution source for this market will be official information from the UFC.
