Detroit is a 51.5c home favorite (51c Kalshi, 52c Polymarket) against Chicago at 49.5c (50c Kalshi, 49c Polymarket), which is about as close to a coin flip as an MLB board gets. The two sides sum above 100c, which is the platforms' spread rather than a pricing error. Detroit traded near 59c on August 14 and 57c on August 15 before the White Sox took both games, so the finale has compressed roughly 7c toward the road team. Chicago (64-58) leads the AL Central by 4.5 games over Detroit (60-63) and goes for the sweep behind Sean Burke (7-6, 2.99 ERA) against Drew Anderson (4-4, 3.91 ERA).
Chicago and Detroit close a three-game set at Comerica Park at 1:40 pm ET on Sunday, August 16, 2026, with the moneyline at 51.5c Detroit and 49.5c Chicago. The White Sox have already won the first two games of the series, 9-5 on August 14 and 4-3 on August 15, and the board has moved with them. Detroit was priced near 59c at the start of the series and 57c a day later before settling into the current pick'em. The standings weight is real: Chicago (64-58) leads the AL Central and Detroit (60-63) sits 4.5 games back with 39 games left on its schedule.
The two books are effectively in agreement on this game. Kalshi has Detroit at 51c and Chicago at 50c. Polymarket has Detroit at 52c and Chicago at 49c. A 1c gap on either side is inside normal book noise, and the fact that the two sides add up to roughly 101c is the platforms' built-in spread, not a signal. Combined volume across the whole game board is about $28K, and the moneyline carries most of it, roughly $7.9K on the Chicago side against $6.6K on Detroit.
Overnight movement was nonexistent. The Kalshi Detroit line printed 51c on every snapshot between 8:24 pm ET on August 15 and 12:04 am ET on August 16, and Polymarket held 52c across the same window. The move worth pricing is the multi-day one: about 7c of compression from the series opener to the finale, driven entirely by results on the field rather than a rotation change or a scratch.
The derivative board agrees this is close, and it leans slightly the other way. The run line prices Chicago -1.5 at 37c against Detroit -1.5 at 33c, so the market rates a two-run-or-better win as more likely for the road team. Team totals say the same thing: Chicago over 3.5 runs sits at 57c and Detroit over 3.5 runs at 55c. The full-game total of 8.5 trades at 47c to the over with over 7.5 at 55c, which puts the market's true number just under 8.5 runs. Polymarket also carries a first-five-innings winner market at Chicago 44c, Detroit 42c, and a tie at 17c, and a run in the first inning trades at 48.5c across both books.
Sean Burke (7-6, 2.99 ERA) starts for the Chicago White Sox and is the better arm on paper by nearly a run of ERA. Drew Anderson (4-4, 3.91 ERA) goes for the Detroit Tigers. The strikeout props draw the same line: Burke 5+ strikeouts trades at 70c and 6+ at 52c, while Anderson 4+ trades at 64c and 5+ at 44c. Those ladders are Kalshi-only and imply Burke is both the deeper starter and the higher-volume bat-misser in this matchup.
That pitching edge is why a road team with the better record still cannot get the market past 50c. Detroit is 32-30 at Comerica Park and Chicago is 27-34 away from home, a 61-point gap in winning percentage that swallows most of the rotation advantage. Chicago's 64-58 mark is built on a 37-24 home record, and the market is pricing the road version of this team, not the division leader's overall line.
The offenses are close to even in the leaderboards. Miguel Vargas leads Chicago with 27 home runs and 71 RBIs, and Chase Meidroth carries the batting average at .280. Detroit counters with Dillon Dingler at 26 home runs and a team-leading 81 RBIs, and Kevin McGonigle hitting .284. Detroit also owns the better run differential of the two clubs, which is part of why a 60-63 team is still priced as a favorite at home against a division leader.
The moneyline resolves to the team that wins the game outright on August 16, 2026, with first pitch scheduled for 1:40 pm ET at Comerica Park. The winning side pays $1 per share and the losing side settles at $0, with no draw outcome in baseball. The run line settles on the final margin, the total settles on combined runs scored by both teams, and first-five-innings markets settle on the score after the top and bottom of the fifth. Both platforms settle from the official MLB final. A postponement moves settlement to the completed makeup game or voids the contract under each platform's suspension rules, and a rain-shortened official game settles on the score at the point the game is called.
Starting pitching gap: Burke's 2.99 ERA against Anderson's 3.91 is the largest single edge on the board and the reason the road team is nearly even money.
Series compression: Detroit has fallen from roughly 59c to 51.5c across three days after losing 9-5 and 4-3, so any late Detroit support would be a genuine reversal.
Home and road splits: Detroit at 32-30 at home against Chicago at 27-34 on the road is the entire case for the 2c favorite tag.
Division stake: Chicago leads Detroit by 4.5 games in the AL Central, so a sweep pushes the gap to 5.5 with 39 games left on Detroit's schedule.
Total pinned near 8.5: Over 8.5 at 47c and over 7.5 at 55c leaves the total market with almost no conviction either way, matching the flat moneyline.
Both clubs carry season-long markets alongside this game. The MLB prediction market hub tracks every game board, division race, and futures contract across Kalshi and Polymarket. For the American League race that sits above this one, the Orioles vs Rays board covers the same-day game involving Tampa Bay, the 74-48 club that leads the league. Team-level pricing for both sides of this series lives on the Chicago and Detroit hubs linked above.
Resolves to the team that wins the Chicago White Sox at Detroit Tigers game played on August 16, 2026 at Comerica Park, first pitch 1:40 pm ET. Each team contract pays $1 per share if that team wins and $0 if it loses; baseball has no draw outcome, so exactly one side settles at $1. The run line settles on the final margin of victory, the full-game total settles on combined runs scored by both teams, and first-five-innings markets settle on the score after the completed fifth inning. Kalshi and Polymarket both settle from the official MLB final score. If the game is postponed, settlement moves to the completed makeup game or the contract voids under each platform's suspension and postponement rules. A game called early but ruled official settles on the score at the moment play is stopped.
As of the morning of August 16, 2026, Detroit is a 51.5c favorite (51c on Kalshi, 52c on Polymarket) and Chicago trades at 49.5c (50c Kalshi, 49c Polymarket). The two sides sum above 100c because each platform builds in a spread.
Detroit is the marginal home favorite at 51.5c, an implied win probability of about 51%. Chicago is the better team by record at 64-58 against 60-63, but Detroit is 32-30 at Comerica Park and Chicago is 27-34 on the road.
Sean Burke (7-6, 2.99 ERA) starts for the Chicago White Sox and Drew Anderson (4-4, 3.91 ERA) starts for the Detroit Tigers. Burke 6+ strikeouts trades at 52c and Anderson 5+ strikeouts at 44c.
Detroit was priced near 59c on August 14 and 57c on August 15 before Chicago won 9-5 and 4-3. That is roughly 7c of compression into the August 16 finale, and the line held flat at 51c on Kalshi through the overnight session.
The game trades on both Kalshi and Polymarket, with about $28K of combined volume across the full board. The 8.5-run total sits at 47c to the over, and over 7.5 runs trades at 55c, placing the market's number just under 8.5.
Watch for a lineup scratch or an early bullpen signal from Detroit, which trails 0-2 in the series. A sweep pushes Chicago's AL Central lead to 5.5 games with 39 games left on Detroit's schedule, so late Detroit support would mark a real reversal of the three-day trend.
