Colts vs. Patriots

Platform comparison

Market context

The Indianapolis Colts face the New England Patriots on 13 August at 7:30 PM ET in what will be a preseason NFL encounter. The prediction market currently implies a 33% probability of a Colts victory, suggesting the Patriots are favoured at roughly 67%. This represents a meaningful gap compared to typical preseason matchup pricing, where home-field advantage and recent roster composition drive most variance.

Preseason games historically exhibit lower predictability than regular-season contests, given variable playing-time allocation and injury-management protocols. The Colts have won their last three preseason meetings against the Patriots, though such records carry limited weight given the turnover in personnel and coaching emphasis between seasons. Current sportsbook lines typically reflect modest point spreads in preseason fixtures—often 2–4 points—making the market's 33% Colts probability somewhat conservative relative to a coin-flip baseline, particularly if the Colts are playing at home or if either team has announced significant starter availability.

Traders should monitor roster announcements in the week preceding the game, particularly injury reports affecting either team's offensive or defensive depth. The Patriots' quarterback situation and the Colts' defensive secondary composition will likely influence line movement. Recent reports from NFL beat writers covering both franchises should clarify whether either side plans extended playing time for key backups or rookies, a factor that can substantially shift preseason outcomes. Settlement occurs at 23:30 UTC on 13 August, allowing for post-game resolution once final statistics are confirmed.

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.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Best Prediction Markets trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
