Broncos vs. Falcons

Platform comparison

Market context

The Denver Broncos face the Atlanta Falcons on 14 August in an NFL preseason encounter scheduled for 7:00PM ET. The 64% crowd probability favours Denver, reflecting their stronger recent regular-season performance and roster depth compared to Atlanta's rebuilding phase. This is a preseason fixture, meaning both teams will likely rotate players extensively, reducing the predictive value of typical strength metrics.

Preseason games historically show wider variance than regular-season contests due to staggered playing time and experimental formations. Denver's 2023 preseason record stood at 2–1, whilst Atlanta went 1–2, but these records carry limited weight for determining outcomes in individual matchups. The Broncos' established offensive line and secondary typically perform more consistently across preseason rotations, which may explain the current probability lean. However, preseason results often hinge on which backup quarterbacks and reserve defenders see extended minutes rather than overall team quality.

Traders should monitor injury reports released in the 48 hours before kickoff, particularly any late withdrawals of key starters. Weather conditions at the venue could also shift the game's character—Denver's altitude advantage matters less in preseason but remains a minor factor. The settlement window closes at 23:00 on 14 August, allowing only same-day resolution. Any postponement would extend the market open until completion, whilst a cancellation without rescheduling would resolve 50-50. Recent NFL preseason scheduling has remained stable, with no widespread postponements reported across the league.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
