Pittsburgh Pirates vs. Cleveland Guardians

Platform comparison

Market context

The Pittsburgh Pirates defeated the Cleveland Guardians 7–1 in their MLB matchup yesterday at Progressive Field, a result that already anchors the 100% YES probability on Polymarket for the Pirates winning this specific contract [1]. Because the game has already concluded with a decisive Pirates victory, the on-chain conditional tokens for this market are effectively locked in, with USDC payouts on Polygon set to resolve automatically once the settlement window closes on 26 July 2026 [1].

Historically, prediction markets that reach 100% certainty before the settlement window closes rarely deviate, as the underlying event is no longer speculative but factual; similar MLB contracts in 2025 and 2024 resolved instantly once final scores were confirmed by official league statistics, bypassing any need for further trading activity [1]. The 100% price reflects the absence of uncertainty rather than crowd optimism, meaning liquidity is thin and the spread is negligible for holders waiting for the USDC payout.

Traders should monitor the official final statistics page for any rare post-game adjustments, though the 7–1 scoreline is already widely reported across major sports data providers [1]. No further announcements, schedule changes, or pitcher dependencies apply, as the game occurred on 19 July at 1:40 PM ET and the result is definitive [2]. The only remaining catalyst is the automated settlement process on Polygon, which will convert the winning conditional tokens into USDC without manual intervention once the 2026-07-26 deadline passes.

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

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Kalshi UK. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

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.

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.
