MLB: Most Home Runs (Team)

Platform comparison

Market context

The market bets on which MLB team will hit the most home runs during the 2026 regular season, with a 2% implied probability favouring a specific outcome. Historically, the team leading in home runs often aligns with the league’s highest-scoring squad, though ties are rare and resolved by run differential or alphabetical order. In recent seasons, teams like the Houston Astros and Los Angeles Dodgers consistently topped the charts, with the Dodgers hitting 249 home runs in 2023 and the Astros 226 in 2022, setting a high benchmark for 2026 contenders [1].

Traders should monitor offseason roster moves, particularly power-hitter acquisitions, and early-season spring training performance, as these directly influence home run potential. Shohei Ohtani, projected to lead with 52 home runs, could anchor a team’s total if he remains with a strong lineup [1]. Key catalysts include mid-season injury reports, pitching rotations affecting offensive output, and any schedule adjustments due to weather or events. Polymarket displays this as 2% implied probability, whereas Kalshi and Betfair typically show decimal odds (around 50.00), and fee structures vary: Polymarket charges 2% on winnings, while Smarkets offers 0% but requires KYC for larger trades, affecting liquidity and accessibility for UK-based traders.

Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.
