Pittsburgh Pirates vs. New York Yankees

Platform comparison

Market context

The Pittsburgh Pirates are at Yankee Stadium to face the New York Yankees in the first game scheduled for 1:35pm ET, and the contract’s **37% YES** pricing is below most sportsbook and model views of the Pirates’ chance to win. ESPN’s live preview shows the Yankees at **55.7%** to win, while FanDuel’s research page has New York at **53.8%** and BetMGM’s model at **53.7%**; by contrast, the market is implying a Pirates win rate of just over one-third. [12][11][9]

That gap matters because comparable pricing across books has generally put New York in the **-168 to -188** range, which corresponds to roughly a **63% to 65%** raw favourite before vig, while Pittsburgh has been posted between **+136 and +156** on the moneyline. [2][3][6] In other words, the prediction market is pricing the underdog more aggressively than the consensus sportsbook board, even though analysts still lean Yankees; CBS Sports’ simulation work also points to a lower-scoring game, projecting **9.3 combined runs** and an Under lean, which can matter in a one-run outcome. [6]

The main catalysts for traders are late lineup and pitching-confirmation news, because the game preview has already tied the matchup to **Mitch Keller vs Gerrit Cole** as probable starters, and any change there would move both the moneyline and the market-implied win probability. [1] Schedule risk is low but not zero: the contract stays open if the game is postponed, and only resolves 50-50 if it is cancelled with no make-up or ends tied, so weather, delay announcements, and official starter confirmations are the key dependencies to watch into first pitch.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

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 Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi vs Polymarket trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
