MLB: Team to win 100+ games

Platform comparison

Active sub-markets

Market context

The 2026 MLB regular season will run 162 games, and this market prices the likelihood that a single unnamed team reaches 100 wins at 3%, implying roughly a 1-in-33 chance. Reaching the century mark remains genuinely difficult; only 15 teams have managed it since 2010, with the 2022 Houston Astros (106 wins) and 2019 Los Angeles Dodgers (106 wins) among the most recent examples. The 100-win threshold typically requires sustained excellence across a full season, elite pitching depth, and minimal injury disruption—a combination that even well-resourced franchises struggle to assemble consistently.

The consensus at 3% YES reflects the baseline rarity of 100-win seasons rather than team-specific weakness. Historical data shows roughly 2–3 teams per season exceed 100 wins across both leagues, making the individual-team probability genuinely sparse. However, value considerations hinge entirely on which team the market references. A defending division champion with a proven core and strong front-office continuity might warrant odds closer to 8–12%, whilst a rebuilding outfit or one facing significant roster turnover would justify single-digit pricing. Traders should monitor off-season roster moves, injury reports from spring training, and any managerial or coaching changes announced before late March 2026, as these fundamentally reshape win-projection models.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.

FAQ

Is this market available outside the US?

PolyGram is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does it cost to trade on PolyGram?

Zero. PolyGram routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
