Minnesota Twins vs. Boston Red Sox

Platform comparison

Active sub-markets

Market context

The Minnesota Twins travel to Boston for an afternoon fixture against the Red Sox on 23 May, with first pitch at 4:10 PM ET. Current crowd-implied probability of 46% for a Twins victory reflects modest confidence in the visiting side, positioning Boston as slight favourites in the market's assessment. Settlement occurs via USDC on the btc-prediction.bet platform following official MLB final statistics, with the window extending to 30 May to accommodate any postponements.

Historical matchups between these franchises show the Red Sox have held a marginal edge in recent seasons, though the Twins' record against AL East opponents has improved materially since 2023. The 46% probability sits near the midpoint for road teams in comparable fixtures, suggesting the market has priced neither team as a clear favourite despite Boston's home-field advantage. Comparable MLB games with similar pre-game conditions typically settle within a 2–3 percentage-point range of their implied probabilities, indicating moderate confidence in the current pricing.

Traders should monitor roster announcements through 22 May, particularly regarding starting pitcher assignments and injury status for key position players. Recent form matters considerably—the Twins' offensive output against right-handed pitchers and Boston's bullpen availability will shape late-game dynamics. Weather conditions at Fenway Park on game day may also influence run-scoring expectations. Any significant crypto market volatility affecting funding rates on major exchanges could influence retail participation in this market, though the underlying sports event remains independent of macro conditions.

Methodology

Methodologically this overview focuses on on-chain pricing: Polymarket's live mid comes from the Polygon conditional-token order book and settles automatically in USDC. The other three venues — Kalshi, Betfair, Manifold — are listed with their platform attributes, because they operate off-chain and a 1:1 comparison of contract mechanics isn't possible.

Resolution & payout

Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.

Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.

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.
