Market context
The Miami Dolphins face the Washington Commanders on 14 August at 7:00 PM ET in what is formally classified as a preseason National Football League contest. The 63% crowd-implied probability favouring Miami reflects confidence in the Dolphins' roster depth and recent offensive momentum, yet this figure sits meaningfully higher than consensus sportsbook lines, which typically price the Dolphins between −2.5 and −3.5 points. This divergence suggests prediction-market participants are pricing in either superior information about player availability or a structural overweight toward home-field advantage in preseason matchups.
Preseason games historically exhibit greater volatility than regular-season contests because coaching staffs rotate lineups unpredictably, prioritising injury prevention and evaluation over win-maximisation. The Dolphins' implied 63% probability aligns with their status as a stronger franchise on paper, yet preseason outcomes depend heavily on which starters see meaningful snaps. Recent reporting from NFL beat writers indicates both teams plan to rest key defensive personnel during this fixture, which typically compresses scoring and increases the likelihood of lower-variance outcomes.
Traders should monitor official injury reports released 48 hours before kickoff, as unexpected absences among projected starters can shift the probability substantially. Weather conditions at the stadium and any last-minute roster moves—particularly among backup quarterbacks or offensive linemen—represent material catalysts. The settlement window closes at 23:00 UTC on 14 August, allowing minimal time for post-game verification, so any administrative delays in official scoring could affect resolution timing.

Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
