Market context

The Boston Red Sox face the Tampa Bay Rays on 9 June at 6:40 PM ET in a regular-season MLB fixture. Settlement occurs on 16 June, allowing for postponements or rescheduling within that window. The 0% implied probability reflects minimal trading activity rather than certainty; thin order books on niche sports matchups often display extreme prices until deposit flows and liquidity arrive.

Historical precedent suggests mid-June AL East contests between these franchises attract modest volume unless injury news or playoff implications shift trader attention. The Red Sox and Rays have traded divisional advantage multiple times over the past decade, yet single regular-season games rarely move significant capital unless tied to injury announcements or roster transactions. Comparable June fixtures in prior seasons show probability movement clusters around 40–60% ranges once deposit infrastructure settles and traders access funding rails—whether SEPA transfers, Klarna instalments, or USDC on-chain settlement.

Key catalysts include starting pitcher confirmation (typically announced 24–48 hours before first pitch), weather delays in the Boston area, and any late-roster moves affecting either bullpen depth. Traders monitoring MLB injury reports and team announcements should watch for updates on Red Sox or Rays position players through early June. Deposit friction remains material: traders using slower payment methods (bank transfers) versus faster rails (USDC) may miss sharp line movements if news breaks close to game time. Book depth typically improves as the fixture date approaches and funding clears across payment processors.

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

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
