Market context

The Colorado Rockies travel to Arizona to face the Diamondbacks on 24 May at 4:10 PM ET in a regular-season Major League Baseball fixture. The settlement window closes on 31 May at 20:10 UTC, allowing five trading days post-match for resolution confirmation. Under MLB's official rulebook, the visiting Rockies must overcome Arizona's home-field advantage; both teams' records, injury status, and recent form will determine the outcome, with no draw possible in baseball.

From a regulatory standpoint, this market's accessibility depends on the trader's jurisdiction. Under Germany's GlüStV (gambling licensing statute), prediction markets on sports outcomes remain subject to state-level licensing requirements, though some operators hold exemptions for financial derivatives. The US CFTC has clarified that binary sports contracts fall outside its direct purview when operated by licensed platforms, though state-level gambling laws apply. The "no-KYC up to $1,500" threshold commonly cited by platforms means traders can deposit and trade positions below that amount without identity verification in certain jurisdictions, though this does not exempt the underlying market from settlement reporting or tax obligations in the trader's home country.

Catalysts for this match include roster announcements, weather conditions at Chase Field, and any last-minute injuries to key players. The Rockies' recent performance against NL West opponents and Arizona's home record in late May provide comparative context. Traders should monitor official MLB injury reports and team news feeds through 24 May, as starting pitcher assignments and bullpen availability often shift market expectations in the final 48 hours before first pitch.

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

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

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.

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 PolyGram?

Zero. PolyGram routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.

Do I need to KYC for this market?

Not under $1,500 of lifetime trading volume. Above that threshold, PolyGram triggers a quick verification flow that finishes in 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.
