MLB: Longest Winning Streak
Description
This market will resolve according to the bracket corresponding to the longest winning streak by a single team during the 2026 MLB regular season. If the 2026 MLB regular season is cancelled, postponed after October 11, 2026, 11:59 PM ET, or the longest winning streak cannot be determined within that timeframe, this market will resolve to “Other”. The resolution source for this market will be official information from the MLB; however, a consensus of credible reporting may also be used.

Issue:
Polymarket and Kalshi resolve on different dimensions of the same event: Polymarket on streak LENGTH (quantitative brackets), Kalshi on TEAM IDENTITY (categorical). Additionally, Polymarket includes explicit cancellation and fallback logic ("Other"), while Kalshi does not.Hero Tip:
Treat these as complementary markets, not substitutes. Use Polymarket for streak-length predictions and Kalshi for team-specific predictions. Be aware that Polymarket has a defined cancellation protocol (resolves to Other if season cancelled or delayed past Oct 11, 2026, 11:59 PM ET), but Kalshi's cancellation behavior is not explicitly stated. If you hold positions on both platforms, verify that both use the same official MLB data source to avoid settlement disputes.Critical Divergence Points:
- Polymarket: Resolves on the LENGTH of the longest winning streak across all teams, using eight mutually exclusive brackets (0-9, 10-12, 13-15, 16-18, 19-21, 22+, Other). Includes explicit cancellation clause: if 2026 season is cancelled, postponed after October 11, 2026, 11:59 PM ET, or the longest streak cannot be determined within that timeframe, resolves to Other. Source: Official MLB or credible consensus reporting.
- Kalshi: Resolves on the TEAM IDENTITY that records the longest winning streak. Offers 30 binary markets (one per MLB team), each resolving to Yes if that team has the longest streak, implicitly No otherwise. No explicit cancellation clause or fallback logic provided. Source: Pro Baseball 2026 regular season records.
