Intro

This market tracks whether the Cincinnati Reds will have the highest Automated Ball/Strike (ABS) challenge success rate during the 2026 MLB regular season on Polymarket, with the leading outcome currently at 93.1%. The resolution source is baseballsavant.mlb.com/abs. Watch for the resolution on October 11, 2026, which will determine the final ABS challenge success rates for all teams and settle this market.

Polymarket

This market will resolve according to the team that records the highest ABS challenge won% during the 2026 MLB Regular Season. If two teams tie for the highest ABS challenge won%, this market will resolve in favor of the team that records more challenges won during the 2026 MLB regular season. If a tie still persists, this market will resolve in favor of the team whose listed team name comes first alphabetically. If the 2026 MLB regular season is cancelled, postponed after October 11, 2026, 11:59 PM ET, or the team with the highest won% 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 (https://baseballsavant.mlb.com/abs); however, a consensus of credible reporting may also be used.

Frequently asked questions

On Polymarket, the MLB challenge success rate market tracks which team will post the highest successful challenge rate during the 2026 MLB regular season. The dashboard displays real-time odds, historical price movements, and trading volume for this prediction market. Traders buy and sell shares based on their conviction about which franchise will lead the league in overturning umpire calls through the challenge system. This market aggregates collective forecasts from participants who analyze team-specific challenge strategies, replay review success patterns, and managerial tendencies throughout the season.

Prediction market odds and sportsbook odds serve different purposes. Sportsbooks focus primarily on game outcomes and point spreads, while this market isolates a specific statistical achievement—the highest challenge success rate. Prediction markets like Polymarket reflect aggregate trader beliefs about which team will lead in this metric, often incorporating detailed statistical analysis and real-time season data. Sportsbooks typically don't offer direct odds on challenge success rates, making prediction markets a unique venue for pricing this specialized outcome.

On Polymarket, traders set prices through continuous order-book matching, where buy and sell orders determine the probability of each outcome. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Shares representing each team's likelihood of achieving the highest challenge success rate trade between 0 and 1 dollar, with the price reflecting the collective market estimate. As new information emerges—such as early-season challenge data, managerial changes, or replay review trends—traders adjust their positions, causing prices to shift in real time.

This market resolves around Oct 11, 2026, after the 2026 MLB regular season concludes. The outcome is determined by identifying which team recorded the highest challenge success rate across all regular-season games. Resolution is verified against credible public sources including official MLB statistics and league records. Once the final regular-season data is compiled and confirmed, the market settles to the winning team, and traders holding the correct outcome receive their payout.

Early-season challenge data will be the primary driver of price movement, as teams' actual success rates become measurable. Managerial changes or new replay review coordinators could shift expectations for specific franchises. Injuries to key players or umpires known for particular tendencies may influence challenge strategy and success rates. Rule clarifications or interpretations from MLB could alter how challenges are adjudicated league-wide. Additionally, mid-season trades and roster adjustments may affect team performance and, indirectly, their challenge success patterns through the remainder of the season.
