About This Event
This market will resolve according to the result of the season series between the Chicago Bears and Detroit Lions during the 2026-27 NFL regular season. If the Chicago Bears win the season series, this market will resolve to “Bears”. If the Detroit Lions win the season series, this market will resolve to “Lions”. If the Chicago Bears and Detroit Lions tie the season series, this market will resolve to “tie”. If any scheduled game between the listed teams during the 2026-27 NFL regular season is cancelled, not completed, or otherwise does not produce an official result — including due to a shortened, truncated, or early-ended season — the season series will be determined solely using official results of completed games. If the season is cancelled, no games between the teams are completed, or the result of the season series cannot otherwise be confirmed by January 26, 2027, 11:59 PM ET, this market will resolve 50-50. The primary resolution source for this market will be information from the NFL, however a consensus of credible reporting will also be used.
This analysis is awaiting a background update, so its prices may be older than the odds above.

What the contract measures
This snapshot covers one Polymarket event, "Pro Football: Bears vs. Lions Season Series Winner," which "will resolve according to the result of the season series between the Chicago Bears and Detroit Lions during the 2026-27 NFL regular season" [1]. The three contracts are not interchangeable. One asks whether the series ends in a tie, and two ask whether the Bears or the Lions win it. The rules say the market "will resolve to "Bears"" if the Bears win, "Lions" if the Lions win, and "tie" if the series is tied [1].
The rules also set a fallback. If the season is cancelled, no games are completed, or the result "cannot otherwise be confirmed by January 26, 2027, 11:59 PM ET, this market will resolve 50-50" [1]. The listed end time is 2027-01-27T04:59:00.000Z [1]. That time is a close date in the contract listing, not an announced event date.
Reading the snapshot
The provider observed these prices at 2026-10-18T03:00:06.384Z, and the saved record was retrieved at 2026-10-18T04:19:56.606Z [1]. These are snapshots, not current quotes. The Yes prices were 0.59 for the tie contract, 0.31 for the Bears contract, and 0.31 for the Lions contract [1]. The No prices were 0.41, 0.69, and 0.69 respectively.
These numbers are the quoted prices at one observation time. They are not executable quotes, and they are not verified probabilities. The three Yes prices do not sum to one, which is a feature of this snapshot and does not by itself indicate any trading opportunity. Volume and price levels here do not indicate how many traders hold a view or how liquid each contract is.
Because all three contracts come from one event on one platform, no cross-platform comparison is possible here. The contracts cannot be averaged with prices from other providers.
What remains uncertain
The sample covers all three saved markets for this event: 3 included out of 3 total, with no partial sample flag [1]. The saved record states that this "does not establish that the providers list every possible real-world outcome" [1]. The evidence does not show any other outcomes, so none can be assumed or priced here.
The evidence does not include any game schedule, results from completed games, or reporting on the teams' seasons. It also does not explain why prices were at these levels. Readers should check the current contract page and its listed rules before drawing conclusions, since this snapshot describes only the moment it was observed.

Saved Oct 18, 2026 UTCOverview
This PredictPedia entry covers a sports contract tied to the season series between the Chicago Bears and Detroit Lions during the 2026-27 NFL regular season [1]. The contract asks who wins that season series, with three possible results. If the Bears win the series, the market resolves to "Bears". If the Lions win, it resolves to "Lions". If the two teams split the series, it resolves to "tie" [1]. The rules also explain what happens when games do not finish normally. If any scheduled game between the two teams is cancelled, not completed, or otherwise does not produce an official result, including because the season is shortened, truncated, or ends early, the series is decided only by the official results of games that were completed [1]. If the season is cancelled, if no games between the teams are completed, or if the series result cannot be confirmed by January 26, 2027, 11:59 PM ET, the market resolves 50-50 [1]. That deadline is a term in the contract rules. The supplied evidence does not present it as a scheduled event or announced date. The primary resolution source is information from the NFL, and a consensus of credible reporting is also used [1]. The listed end time for the event is 2027-01-27T04:59:00.000Z [1]. That is the contract's listed end time, not a record of when the season series was decided. The Bears and Lions are described in the supplied background as an NFL rivalry [2]. The evidence does not list the 2026-27 game dates, opponents' schedules, or team form, so the contract should be read as a rules-based question about the series outcome rather than as an analysis of either team's chances.
Historical Context
The supplied background identifies the Bears-Lions rivalry as a National Football League rivalry between the two franchises [2]. A separate supplied article covers the 1985 Chicago Bears season, which was the Bears' 66th NFL season and their fourth under head coach Mike Ditka [3]. That article concerns the Bears' 1985 season and does not describe the Bears-Lions series or the 2026-27 contract, so it does not establish any historical record between these two teams.
Why It Matters
The contract measures a single outcome: which team wins the season series between the Bears and the Lions in the 2026-27 NFL regular season, or whether the series ends in a tie [1]. Its rules are designed so that cancelled or incomplete games are handled by counting only official results of completed games, and so that a cancelled season or an unconfirmed result by the stated deadline leads to a 50-50 resolution [1]. Because the NFL is the primary resolution source with credible reporting as a secondary check, the contract's resolution depends on how those sources report the results [1]. The saved market snapshot, observed on 2026-10-18 at 03:00 UTC, lists three contracts from the same event. The tie contract showed a Yes price of 0.59 and a No price of 0.41. The Bears contract showed a Yes price of 0.31 and a No price of 0.69. The Lions contract showed a Yes price of 0.31 and a No price of 0.69 [1]. These are observed prices from a single saved snapshot, not executable quotes or verified probabilities, and the contracts are not a basis for arbitrage merely because their prices differ. All three saved markets for this event are included, but the sample does not establish that the provider lists every possible real-world outcome.
