Detroit Tigers vs. New York Yankees

Platform comparison

Market context

The upcoming MLB fixture sees the Detroit Tigers travel to face the New York Yankees on Tuesday, 30 June, with the game scheduled to commence at 7:05 PM ET. This specific market resolves to "Detroit Tigers" if they secure the victory, while a Yankees win triggers the opposite outcome. The current crowd-implied probability sits at 92% YES for the Tigers, a figure that starkly contradicts traditional betting lines where the Yankees hold a clear advantage as favourites, with moneylines ranging from -137 to -141 and a predicted win probability of 65.5% for New York according to numberFire[1][5].

Historically, such divergences between public sentiment and algorithmic models often signal conditional order opportunities for power-users, particularly when the public backing a team with a 36-49 season record clashes with the superior 48-36 standing of the Yankees[2][5]. Comparable cases in MLB prediction markets show that when the public money heavily favours an underdog with a losing record, the market frequently corrects once the game begins, unless a specific catalyst like a pitching injury alters the dependency structure. Traders approaching this programmatically should monitor the live runline, where the Tigers are currently +1.5, suggesting the market expects a narrow margin rather than a blowout[1][3].

Key catalysts to watch include the official starting pitcher announcements, which remain the primary dependency for any conditional order strategy, and the over/under total set at 7.5 runs, indicating expectations for a moderate scoring game[1][5]. Recent data from oddscrowd highlights that 99% of public money is on the Yankees, yet the market price implies a Tigers win, creating a potential arbitrage window for those executing copy-trading bots on the discrepancy[6]. Traders must verify the final roster updates before the settlement window closes on 7 July 2026, as any postponement or cancellation would reset the resolution to a 50-50 split, nullifying the current high-probability stance[1][8].

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

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 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.
