Market context

The Colorado Rockies face the Arizona Diamondbacks on 24 May at 4:10 PM ET in a regular-season MLB matchup. The 1% implied probability assigned to a Rockies victory represents an extreme underdog positioning, suggesting the market expects Arizona to win with near-certainty. This probability divergence warrants examination against conventional sportsbook lines and recent team performance, particularly given that prediction markets and traditional betting venues occasionally reflect different information sets or risk appetites.

Historical context shows that 1% probabilities in sports markets rarely reflect genuine certainty; rather, they typically indicate either substantial analytical consensus around one outcome or low liquidity concentrating trader positions. In MLB regular-season games between non-elite teams, such extreme probabilities often emerge when one squad carries significant injury burdens, faces a pronounced pitching disadvantage, or enters a fixture on the tail end of a gruelling schedule. The Rockies' home-field advantage at Coors Field—where run-scoring environments differ markedly from league average—provides a structural factor that occasionally produces upset outcomes even when pre-game expectations heavily favour opponents.

Traders should monitor roster updates through 24 May, particularly any late-breaking injury announcements affecting either team's starting rotation or key position players. Arizona's recent form, win-loss record, and any weather developments at Denver's high altitude warrant attention, as precipitation and temperature fluctuations can meaningfully influence ball flight and game dynamics. The settlement window extending to 31 May accounts for potential postponement, though the resolution mechanism specifies 50-50 splits only for cancellations without make-up games—a relatively rare occurrence in modern MLB scheduling.

Methodology

This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.

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.

FAQ

Is this market available outside the US?

PolyGram 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.

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.
