What the contract measures

This event is a season series market for the 2026-27 NFL regular season between the Arizona Cardinals and San Francisco 49ers. The primary resolution source is "information from the NFL, however a consensus of credible reporting will also be used" [1]. The rules say the market resolves to "Cardinals" if the Cardinals win the season series, to "49ers" if the 49ers win, and to "tie" if the teams tie [1].

The rules also address incomplete seasons. If a scheduled game is cancelled or otherwise produces no official result, the series is decided only by completed games. If the series cannot be confirmed by January 26, 2027, 11:59 PM ET, the market resolves 50-50 [1]. That deadline is a contract rule, not an announced event date.

The saved event lists an end time of 2027-01-27T04:59:00.000Z [1].

Reading the snapshot

The provider observation time is 2026-10-15T16:13:13.851Z, and the source was retrieved at 2026-10-15T18:34:26.145Z [1]. These prices describe that earlier observation and are not live quotes.

The sample contains two separate contracts. The first asks whether the 49ers win the series, with a Yes price of 0.54 and a No price of 0.46 [1]. The second asks whether the series ends in a tie, with a Yes price of 0.338 and a No price of 0.662 [1]. Each contract is read on its own terms. The two prices are not combined into a single probability.

The saved sample does not include a separate contract for a Cardinals series win. Because that outcome is absent from the sample, this comparison cannot state its price. Its absence does not mean it has a lower price.

Volume is not included in this snapshot, so it cannot indicate liquidity or the number of traders.

What remains uncertain

The sample is complete for the saved provider event. It includes all two saved markets and is not marked as partial [1]. That does not show that the provider lists every possible real-world outcome.

The prices are snapshots from a past observation, not executable quotes, and they should not be treated as verified probabilities. The evidence does not explain why the prices took their observed values. It also does not show whether the 50-50 rule, the regular season schedule, or any future game result will affect the market, beyond the rules quoted above.
