Boston Red Sox vs. Colorado Rockies

Platform comparison

Active sub-markets

Market context

The underlying event is the Major League Baseball match between the Boston Red Sox and Colorado Rockies held at Coors Field on 22 June 2026, which concluded with a 3–2 victory for the Rockies after Jake McCarthy’s three-run triple in the ninth inning[1][2]. This outcome renders the current crowd-implied probability of 0% for a Red Sox win factually accurate, as the game has already been settled.

Historical precedents in MLB prediction markets show that probabilities collapse to zero once a result is confirmed, mirroring cases where late-inning rallies, such as the Rockies’ 2026 ninth-inning surge, invalidate pre-game favourites[1][7]. Comparable settlements in sports markets confirm that no further trading occurs post-final whistle, aligning with regulatory standards that treat completed events as closed for resolution.

Traders should monitor official MLB announcements regarding future fixture cancellations or postponements, though this specific market is already resolved[3][9]. Key dependencies include the governing body’s final statistics, which serve as the primary resolution source, and any potential regulatory updates from the US CFTC or German GlüStV that might affect accessibility for non-KYC users up to £1,500, a threshold that currently permits broad participation without identity verification for this settled market.
