Pittsburgh Pirates vs. New York Yankees

Platform comparison

Market context

Polymarket’s contract is pricing the **Pirates at 37% yes**, which is materially below the market view for a Pittsburgh win and implies the **Yankees are the clear favourite** in the underlying game. On-chain, that price is expressed through USDC-settled, Polygon-based conditional tokens, so the number reflects traders’ current view of who will win the game, not just a conventional sportsbook line.

That 37% sits beneath the range implied by the public odds and model picks available today. Covers lists New York around **-165**, Action Network shows the Yankees as a stronger favourite at **-140** on the moneyline, and several preview/model sources put New York near the mid-50s in win probability, while Oddspedia’s aggregated probabilities still favour the Yankees at about **63%**.[2][3][6][7][8] For a hands-on Polymarket user, that gap suggests the contract is trading with a wider underdog premium than the consensus estimates, which can matter if you are comparing the on-chain price to external baseball pricing rather than to the binary market itself.

The main catalysts are the **confirmed line-ups, starting pitchers, late scratches, and any weather or schedule changes** before first pitch; those inputs can move a moneyline quickly and, by extension, a conditional-token market. The game is scheduled for **July 22 at 1:35pm ET**, and if it is postponed the market stays open until completion, while a cancellation or tie would resolve 50-50, so traders also need to watch for any pre-game suspension or rescheduling notices.[1][2][3]

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

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?

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.

Do I need to KYC for this market?

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

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.
