The Detroit Tigers open a series against the Baltimore Orioles as the 53c moneyline favorite, with Kalshi and Polymarket both landing on 53c and the Orioles at 48.5c (49c Kalshi, 48c Polymarket). This is a near coin-flip between two sub-.500 clubs: Baltimore is 51-55, Detroit is 50-56 but holds home-field at Comerica Park, where the Tigers are 29-25. Detroit sends Keider Montero (7-5, 3.14 ERA) against Baltimore right-hander Kyle Bradish (7-9, 3.49 ERA). The live board above carries the current cross-platform prices; first pitch is 6:40 PM ET on Monday, July 27, 2026.
The Orioles vs Tigers moneyline is priced as close to a toss-up as the board gets: Detroit sits at 53c and Baltimore at 48.5c, and the two exchanges are effectively locked together on the game markets. Detroit is 53c on both Kalshi and Polymarket, and Baltimore is 49c on Kalshi versus 48c on Polymarket, a one-cent gap. DraftKings has Detroit at -120, which implies roughly 55%, so the prediction-market price and the sportsbook line agree that the Tigers are the marginal favorite by virtue of hosting.
Orioles vs Tigers Market Context
Neither team enters with a winning record. Baltimore is 51-55 overall and 22-28 on the road, while Detroit is 50-56 overall but a more respectable 29-25 at home. That home split is most of the reason a 50-56 team is favored over a 51-55 team on this line. The total is set at 8.5 runs, trading at 48.5c (49c Kalshi, 48c Polymarket), with the Over 7.5 alt at 57c and the Over 9.5 alt at 38c, so the market sees a fairly average-scoring game. On the run line, Baltimore at -1.5 is 37c and Detroit at -1.5 is 34.5c (34c Kalshi, 35c Polymarket), reflecting how tight the moneyline is: neither side is a strong favorite to win by two or more.
The lineups are close on paper. Detroit leans on Riley Greene (.282) and Dillon Dingler (22 home runs, 68 RBIs), while Baltimore counters with Pete Alonso (22 home runs, 67 RBIs) and Taylor Ward (.253). Both teams' leading power bats sit at exactly 22 home runs, which is part of why the board treats this as a coin flip.
The Orioles vs Tigers Pitching Matchup
The starters are the reason the total is modest. Keider Montero (7-5, 3.14 ERA) has been Detroit's steadier arm, and the board prices his strikeout prop conservatively: his Over 4.5 strikeouts line sits at 47.5c and his Over 3.5 at 54c. Kyle Bradish (7-9, 3.49 ERA) has a worse win-loss record but an ERA within four-tenths of a run; his Over 5.5 strikeouts prop is 47c. Kalshi and Polymarket diverge most on these strikeout props (Montero's Over 3.5 is 67c on Kalshi against 41c on Polymarket), so the pitcher props are where a cross-platform shopper finds the widest gaps, not the moneyline.
When the Orioles vs Tigers Market Resolves
The market resolves on the outcome of the game at Comerica Park on Monday, July 27, 2026, scheduled for 6:40 PM ET. The moneyline pays the team that wins the game. The run-line and total contracts settle on the final score, and each contract is settled on Kalshi and Polymarket once the game goes final. If the game is postponed or suspended, the contracts settle per each platform's posted rules for delayed or shortened games.
Key Orioles vs Tigers Factors
Home-field weight: Detroit is 29-25 at Comerica Park and Baltimore is 22-28 on the road, which is the main input carrying a 50-56 team to favorite status.
Starting pitching: Keider Montero (3.14 ERA) versus Kyle Bradish (3.49 ERA) is a near-even matchup that keeps the total at 8.5 and the moneyline inside 53c-to-48.5c.
Line stability: Detroit opened around 52c on Kalshi overnight and sits 53c now, a one-cent move, so the market has held the Tigers as a marginal favorite all day.
Cross-platform read: the game markets are locked (Detroit 53c on both books), so the value gaps live in the strikeout props, where Kalshi prices Montero and Bradish higher than Polymarket.
Power bats: Dillon Dingler (22 home runs) for Detroit and Pete Alonso (22 home runs) for Baltimore anchor the home-run props, with Alonso's Over 0.5 at 15c.
