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 the current crowd-implied probability of 2% YES suggesting the outcome is viewed as highly unlikely for the selected team. If teams tie, the resolver prioritises total runs scored, then run differential, and finally alphabetical order of the team name.

Historically, the team leading in home runs has often been a powerhouse offence like the Houston Astros or Los Angeles Dodgers, who routinely post 250+ homers in a season. In 2024, the Astros led with 261, while the Dodgers followed closely with 259, illustrating how tight the race can be even among elite teams [1]. A 2% implied probability implies the market sees the selected team as a long shot compared to these consistent leaders, unless a major roster shift or breakout performance alters the trajectory.

Traders should monitor spring training lineups, free-agent signings, and early-season power metrics as key catalysts. Recent projections place Shohei Ohtani at 52 home runs for 2026, which could significantly boost his team’s total if he remains healthy [1]. Any announcement regarding Ohtani’s team or other high-upside hitters like Aaron Judge or Juan Soto will directly impact the odds. Compare Polymarket’s decimal odds and lower fees against Kalshi’s KYC requirements and Betfair’s liquidity depth to assess where the best value lies on this specific outcome.

Methodology

We read MLB: Most Home Runs (Team) from four platform perspectives: Polymarket (on-chain CLOB), Kalshi (CFTC-regulated exchange), Betfair Exchange (sports book exchange), Smarkets (peer-to-peer betting exchange). Polymarket's live mid is the canonical probability; the side-by-side columns benchmark fees, KYC, settlement currency and deposit rails so you can choose the venue that fits your jurisdiction and trade size.

Resolution & payout

Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.

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.
