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 matchup. Polymarket currently prices this contract at 39% probability for a Colts victory, implying roughly 61% confidence in a Patriots win. The settlement mechanism on Polygon uses conditional tokens backed by USDC, with the market remaining open should postponement occur and resolving 50-50 only in the event of cancellation or a tied result with no rescheduled game.

Preseason NFL contests historically show less predictive power than regular-season play, yet market pricing often reflects roster depth, injury status, and coaching priorities rather than abstract team strength. The Patriots have won their last three preseason meetings against Indianapolis, though both franchises rotate significant portions of their squads during August fixtures. Recent preseason markets have typically favoured established defensive units and teams with settled quarterback situations; New England's defensive reputation and continuity in that unit may explain the current implied lean towards a Patriots result.

Traders should monitor roster announcements through the settlement window, particularly injury reports affecting either team's key defensive players or backup quarterbacks who often see extended preseason action. The NFL's official injury report, typically released 90 minutes before kickoff, frequently moves preseason markets as teams confirm participation status. Weather conditions at the venue and any last-minute scheduling adjustments remain secondary catalysts, though the fixed kickoff time and established venue reduce uncertainty compared to regular-season contests.

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

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.

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.

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.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

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

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
