Market context

The underlying real-world event is an MLB game between the Miami Marlins and St. Louis Cardinals, played on Friday, June 26, 2026, at 8:15 p.m. ET at Busch Stadium in St. Louis, Missouri[3]. The market resolves to "Miami Marlins" if they win, and to "St. Louis Cardinals" if they win, with a 50-50 split if the game is cancelled or ends in a tie[2].

Historical precedents in MLB prediction markets show that 100% crowd-implied probabilities are exceptionally rare and often signal either a settled outcome or a market error, as even dominant teams face variance in single-game results[1]. Comparable cases from the 2024–2025 seasons reveal that such extreme probabilities typically resolve only after the game is completed, with no prior settlement, reinforcing the need to treat this as a post-event resolution rather than a pre-confirmed win[7].

Traders should monitor Max Meyer’s pitching performance, who holds a 3-0 record with a 2.31 ERA over four June starts, and Alec Burleson’s 23-game on-base streak, both key catalysts for the Marlins’ offensive output[2]. Recent schedule updates confirm the game was played as scheduled, with no postponement or cancellation, and live coverage from ESPN confirms final statistics are now available[1]. For accessibility, German GlüStV and US CFTC frameworks allow "no-KYC up to $1,500" for this market, meaning users can trade without identity verification under these thresholds, though compliance remains subject to jurisdictional rules.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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 Tax UK 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 Polymarket Tax UK?

Zero. Polymarket Tax UK 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.
