Detroit Tigers vs. San Francisco Giants

Platform comparison

Market context

Polymarket is pricing Detroit Tigers vs San Francisco Giants at **100% YES**, which effectively means the contract is trading as a done deal for the Tigers on Polygon, with USDC collateral backing the conditional tokens. That is consistent with the game having already been played: ESPN’s live odds page shows Detroit lost **2-5** to San Francisco, and the matchup is marked final.[2] In Polymarket terms, the remaining step is settlement to the official result source named in the market rules, not a fresh view on the game itself.

That 100% reading is best understood against the wider market backdrop. Before first pitch, sportsbooks and prediction sites had the Tigers as only a modest favourite or near coin flip, with prices ranging from roughly Detroit **-107 to -143** and San Francisco **-103 to +132**, depending on the book and timing.[3][4][5][7][12][15] That kind of pre-game uncertainty matters because it shows the current contract price is not reflecting sports sentiment but post-event confirmation risk: traders are waiting for the official final statistics to match the observed final score, after which the conditional tokens should resolve to Detroit or, if any extraordinary scoring issue arose, to the market’s contingency rules.

The main catalysts now are administrative rather than sporting: confirmation that the game was completed as recorded, any correction to the official line score, and the timing of the market’s settlement process on-chain. If the contest had been postponed or suspended, the market description says it would stay open until completion; if it had been cancelled or ended in a tie, it would resolve 50-50 instead. For a Polymarket user, the practical watch item is therefore the official MLB result and whether the settlement source accepts the final box score without dispute.

FAQ

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 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 PolyGram 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.
