Pronóstico: MLB: Highest ABS Challenge Success Rate (Team)

Platform comparison

Market context

The 2026 MLB regular season is now the first year featuring the Automated Ball-Strike (ABS) challenge system, where teams contest umpire calls using Hawk-Eye technology. This market bets on which club will achieve the highest percentage of successful challenges by October 11, 2026, with the current crowd-implied probability of 36% favouring a "YES" outcome that a specific team will dominate this metric.

Historical precedents from spring training and the early 2026 season suggest success rates hover near a coin flip, averaging 54% overall, though elite teams like the New York Yankees have already posted 58.7% success rates on 17 challenges [4][8]. In Triple-A play during 2025, only 1.4% of pitches were challenged, indicating that volume matters significantly; a team with a slightly lower percentage but far more attempts could theoretically win the tie-breaker based on total challenges won [3]. The 61.3% success rate seen in the first 12 games of the regular season shows early volatility, meaning teams with aggressive coaching staffs and precise pitch-tracking data are likely to outperform conservative squads [4].

Traders must monitor weekly ABS tracker updates for shifts in challenge frequency and success rates, as teams like the New York Mets and Philadelphia Phillies are currently trailing the Yankees in efficiency [8]. Key catalysts include injury reports affecting pitching staffs, which often drive more challenges, and any rule adjustments regarding the overturn threshold for batters versus pitchers [5]. Recent data from May 18 confirms that nearly 3,000 challenges have been issued, establishing a high-volume environment where consistency over the long season will outweigh short-term spikes [10]. Watch for announcements on coaching staff changes or new pitch-tracking software integrations, as these directly influence a team's ability to overturn calls and secure the highest won percentage.

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
