Colts vs. Patriots

Platform comparison

Market context

The Indianapolis Colts face the New England Patriots in a preseason National Football League matchup on 13 August at 19:30 ET. The market currently prices a Colts victory at 41 per cent implied probability, suggesting modest favouring of the Patriots in what amounts to an exhibition game before the regular season commences in September.

Preseason contests present distinct analytical challenges compared to regular-season play. Historical data shows that preseason outcomes correlate weakly with subsequent regular-season performance, as teams rotate rosters extensively to evaluate depth charts and emerging talent. The Patriots have won 11 of their last 15 preseason games dating to 2019, whilst the Colts hold a more modest recent preseason record. However, preseason results often hinge on coaching priorities—whether a team prioritises starter development, injury prevention, or evaluation of fringe roster candidates—rather than competitive intensity. The current 41 per cent probability for a Colts win reflects uncertainty around these variables rather than fundamental team strength differentials.

Traders should monitor roster announcements and injury reports from both franchises in the week preceding the fixture, as these frequently shift preseason game dynamics. Recent coaching staff changes or strategic shifts in either organisation's approach to preseason play could alter expected outcomes. Weather conditions on game day and any last-minute lineup adjustments warrant attention, particularly regarding which starters each team deploys. The settlement window closes at 23:30 ET on 13 August, allowing minimal time for postponement resolution should weather or unforeseen circumstances delay the fixture.

Methodology

Political prediction markets differ structurally from sports betting: thinner liquidity, longer settlement windows, higher sensitivity to single news events. This page shows the live Polymarket quote for Colts vs. Patriots plus platform attributes for the three reference venues, so you can see at a glance where the deepest market for this question sits.

Resolution & payout

Political markets typically settle on official candidate or agency confirmation. Polymarket uses UMA Optimistic Oracle: a proposer posts the outcome with a bond, the two-hour window opens, then the smart contract pays USDC.

Kalshi settles USD via CFTC clearinghouse, with clearly defined resolution sources (e.g. AP race calls for elections). Betfair settles after the official outcome is registered with the league or agency. Manifold is play-money.

UK Frequently Asked Questions

How accurate are political prediction markets?

Historically more accurate than polls. Polymarket's Brier score on US 2024 elections was ~0.11 — better than 538 (~0.14) and every mainstream poll. Markets aggregate information with real skin in the game.

What resolution source is used for elections?

Polymarket defines the source per contract — usually Associated Press (AP Race Call), Reuters or the official electoral commission. The source is stated in contract details before the market opens.

Which platform has the deepest political liquidity?

Polymarket — by far. US 2024 presidential volume was ~$3.5B vs Kalshi (~$200M) and Betfair (~$120M). Where Polymarket is geo-blocked, brokers like Trump Prediction route into the same order book at 0% fees.

How fast do political markets react to news?

High-liquidity markets move within seconds to minutes. A Trump tweet on the economy can shift the "Trump 2024" market 2-5 points before mainstream media has written anything.

Are UK election prediction markets available from the UK?

Yes. Betfair Exchange and Smarkets offer UKGC-regulated UK election markets (seat counts, party share, constituency results). Polymarket also lists UK election contracts with deeper global liquidity. Betfair winnings are typically tax-free for UK individuals; Polymarket profits are subject to HMRC CGT.
