Where can traders trade NFL championship markets?
Kalshi and Polymarket each list 32 active team contracts for the 2027 champion at this read. Kalshi calls the event 2027 Pro Football Champion. Polymarket calls it Pro Football 2027 Champion. The field covers the same 32 teams, which supports direct venue comparisons.
Kalshi publishes transaction fee documentation based on contract price and quantity. Polymarket publishes its fee documentation and market records. Traders should inspect the live confirmation screen on either venue. Fees, bid-ask spread, and available size can outweigh a small difference between last trades.
Kairos aggregates both venue books and execution. The same football cluster includes NFL playoff odds and Heisman odds. Compare the qualification market, championship market, and college award market from one terminal.
How do the 2027 Super Bowl markets resolve?
Kalshi resolves a team contract Yes if that team wins the 2027 Pro Football Championship. Its Rams contract states: "If Los Angeles R wins the 2027 Pro Football Championship, then the market resolves to Yes." Kalshi names AP, ESPN, and Fox Sports as settlement sources for the event.
Polymarket resolves the event according to the team that wins the 2027 NFL league championship. Its rules state: "This market will resolve according to the team that wins the 2027 NFL league championship." A team eliminated under NFL rules resolves No. A cancelled or delayed championship can resolve to Other under the published March 31, 2027 condition.
Why do Kalshi and Polymarket show different Super Bowl odds?
Separate order books produce separate prices. San Francisco last traded 0.8 points higher on Kalshi. The Rams matched at 11 cents on both venues, while Baltimore differed by 0.1 points. Traders should compare the current bid and ask because a last trade can lag the live book.
Both venues cover the same championship outcome, but each publishes its own edge-case rules and resolution sources. Polymarket includes an Other outcome for a cancelled or late championship. Kalshi states the named-team winner test directly. Read the contract before sending the order.
Championship contracts remain open through a long season, so a September snapshot will not describe the market in January. The table records matched last trades and identifies the venue gap at one exact time. Traders should compare live size, fees, and settlement language before acting. Kairos keeps Kalshi and Polymarket books on one screen with execution beside the data. Start trading on Kairos.
