MLB: Team to win 100+ games

Platform comparison

Market context

The real-world event is whether any single Major League Baseball team wins 100 or more games during the 2026 regular season, a threshold that has been reached only 14 times since 1901 and most recently by the 2022 Los Angeles Dodgers. Historical data shows that 100-win seasons are outliers requiring elite depth, minimal injury, and sustained dominance; the 2024 Dodgers won 98, while the 2023 Braves won 104, confirming that even top contenders often fall just short. With the current crowd-implied probability at 3% YES, the market correctly reflects the extreme rarity of this outcome, aligning with projections that the Dodgers, the 2026 World Series favourites at +180 odds, are expected to win 103 games but face significant variance [1][2].

Traders should monitor the Dodgers’ mid-season roster

FAQ

How are winnings taxed?

Tax treatment varies by jurisdiction. In most countries, prediction market gains are treated as ordinary income or capital gains. We cannot provide tax advice — consult a tax professional for your specific situation.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Polymarket Germany Legal stores an email address and wallet addresses rather than a legal name. Over $1,500 lifetime volume triggers KYC, after which identity is no longer anonymous.

What happens during a tax audit?

You're responsible for documenting your trades. Polymarket Germany Legal exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.

Are prediction markets gambling?

Legally unclear in most jurisdictions. Some interpretations classify them as wagering (gambling regulation applies), others as derivatives (financial regulation applies). There's no global precedent specifically for on-chain prediction markets.

What if regulation changes?

If regulation changes in your jurisdiction (e.g. prediction markets are banned), Polymarket Germany Legal would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
