MLB: Highest ABS Challenge Success Rate (Team)

What you need to know

This market asks which MLB team will be the best at winning ABS challenges during the 2026 regular season. An ABS challenge is when a batter or catcher disputes a ball-or-strike call and asks an automated system — essentially a computer — to review it. The team with the highest percentage of those challenges that turn out to be correct wins this market. Think of it as: which team's players are the sharpest at knowing when the umpire got the call wrong? The market settles on whichever team has the highest challenge win rate — successful overturns divided by total challenges — at the end of the 2026 MLB regular season, using official MLB data from Baseball Savant. If two teams finish tied on percentage, the tiebreaker is total challenges won; if still tied, alphabetical order decides. One important edge case: if the season is cancelled or the data can't be confirmed by October 11, 2026, the market resolves as 'Other' rather than any named team. None of the recent headlines provided relate to this market. They cover geopolitical events, fashion, and local politics — nothing about the 2026 MLB season or ABS challenge data. To track this market, the thing worth watching is the running ABS challenge statistics on MLB's Baseball Savant site as the season progresses. This is genuinely hard to predict because ABS challenge success rates are influenced by many small, unpredictable factors — individual player pitch recognition, how often a team challenges, and even random variance across a season. The market currently prices Atlanta, Baltimore, and Chicago all equally at 37%, which tells you the field is wide open and no team has a clear edge. Many other teams are presumably in the running too. Small sample sizes early in the season can swing the standings dramatically, and the leader could change many times before October.

How this resolves

Resolves October 11, 2026

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.
