Pittsburgh Pirates vs. Cleveland Guardians

Platform comparison

Market context

The Pittsburgh Pirates defeated the Cleveland Guardians 7–1 at Progressive Field on 19 July 2026, confirming the outcome that the prediction market has already priced at 100% YES for the Pirates winning. This result aligns with the market’s resolution logic, which awards a “Pittsburgh Pirates” outcome if they win the game, and closes the settlement window on 26 July 2026 once the event is officially completed [1].

Historically, MLB markets that reach 100% implied probability before game completion are rare and typically reflect either a game already played or a definitive pre-game consensus backed by lineups and venue data. In this case, the 100% figure is not speculative but retrospective, as the match has concluded with a clear Pirates victory. Comparable cases in baseball prediction markets show that when a game finishes before the settlement deadline, liquidity often evaporates rapidly, leaving the market to resolve mechanically against the official final statistics.

For a power-user building programmatic strategies, the key dependency is the official final statistics feed from MLB, which serves as the primary resolution source. Traders should monitor the MLB scoreboard API and any postponement or cancellation notices from the league, though none apply here given the game’s completion. A recent post-game report from the Pirates’ official coverage confirms the 7–1 scoreline and Skenes’ dominant performance, providing the factual anchor for automated settlement scripts [1]. Conditional orders tied to this market would have executed cleanly, with no need for make-up game logic.

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 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 Fees 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.
