MLB: Team to win 100+ games

Platform comparison

Active sub-markets

Market context

The 2026 MLB regular season runs 162 games, and this market settles affirmatively only if the specified team reaches 100 wins by 28 September 2026. A 3% crowd probability reflects the rarity of century-mark seasons; since 2010, only 15 teams have achieved 100+ wins across 17 seasons, with the 2022 Houston Astros (106 wins) and 2023 Tampa Bay Rays (99 wins) among recent contenders. Teams winning 100 games typically combine sustained excellence in both run differential and injury avoidance—the 2019 Los Angeles Dodgers won 106 despite mid-season roster churn, whilst the 2021 San Francisco Giants reached 107 with a balanced roster. The current odds suggest traders view most 2026 rosters as unlikely to sustain the ~.617 win percentage required across a full season.

Regulatory accessibility for this market varies by jurisdiction. Under German GlüStV provisions, prediction markets on sports outcomes face licensing requirements; UK-based operators typically fall under Gambling Commission oversight, which permits fixed-odds wagering on sports events without KYC thresholds up to £1,500 per transaction for certain customer segments. US CFTC jurisdiction applies to derivatives contracts on sports outcomes only if they meet specific criteria around leverage and settlement mechanics; most prediction markets escape direct CFTC reach by operating as binary options with defined payouts. Traders should monitor MLB injury reports, trade deadlines (31 July 2026), and roster construction announcements from their chosen team, as mid-season acquisitions or unexpected departures materially shift win-total trajectories. The market's settlement window closes at season end, allowing no adjustment for late-season collapses or unexpected surges.

Methodology

We track MLB: Team to win 100+ games on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
