Analysis
The market has seen dramatic price appreciation over seven days, surging from 6¢ to 75¢, suggesting either new information favoring Brissett's starter status or shifting market sentiment around Arizona's QB situation. The 24¢ spread and minimal $0 volume indicate severe illiquidity despite $62.96 open interest, making the 75% probability potentially unreliable as a true consensus estimate. The extreme 601.2% implied yield on the No side reflects the wide bid-ask gap and low liquidity rather than genuine market conviction, warranting caution before treating this price as a reliable signal with 149 days to expiration.
Resolution rules
If Jacoby Brissett is officially designated as Arizona's starting quarterback for Week 1 of the 2026-27 Pro Football season, then the market resolves to Yes.
