The most confident price on the August 4, 2026 MLB slate was wrong, and it was wrong by four runs. The Chicago Cubs beat the Los Angeles Dodgers 5-1 at Wrigley Field after prediction markets made the Dodgers a 66c road favorite (66c Kalshi, 65c Polymarket) against the Cubs at 36c. The board carried roughly $1.9M in cross-platform volume on Kalshi and Polymarket, and it settled Cubs 100c, Dodgers 0c. Sportsbooks shared the miss, hanging Los Angeles at -186.
A 66c favorite loses roughly one game in three, so a Dodgers defeat was not the story on its own. The margin was. Chicago won 5-1, held Los Angeles to four hits, and did it one night after taking the series opener 10-5. Across two games at Wrigley Field the Cubs outscored the Dodgers 15-6, and the market still installed the road team as a near two-to-one favorite on the second night.
Kalshi had Los Angeles at 66c and Polymarket at 65c before first pitch, a 1c cross-platform spread that left no value gap on either book. Chicago traded at 36c. The two sides summed to 102c, a 2c overround, which is a tight two-way book by prediction-market standards and a sign that this was a settled consensus rather than a thin or disputed line. Sportsbooks landed in the same place, with DraftKings posting the Dodgers at -186 and a total of 9.0. Two independent pricing systems, one conclusion, one wrong answer.
What the 66c was paying for was the pitching matchup. Tarik Skubal took the ball for Los Angeles carrying a 2.81 ERA against Javier Assad and his 3.58 mark for Chicago, and on paper that gap is most of the difference between a coin flip and a 66c favorite. The instructive part of this result is that Skubal delivered exactly what the price implied. He went 6 innings on 85 pitches, allowed 4 hits and 2 earned runs, walked 2 and struck out 6. The Dodgers lost anyway, which means the losing side of the trade did not come from the input the market was actually paying up for.
Neither side scored in the first, and the only Los Angeles run of the night came in the second on a Kyle Tucker home run. Tucker finished 2-for-3 with the RBI and accounted for half of the Dodgers hit total by himself. Chicago answered in the third, and the game sat 1-1 through five innings, which settled the tied-after-five-innings contract on the board YES.
Assad gave Chicago 5.2 innings of one-run ball on 88 pitches, and then the Cubs bullpen erased the rest of the game. Ryan Rolison, Tyler Ferguson, Ryan Zeferjahn and Jacob Webb combined for 3.1 innings without allowing a hit. Los Angeles went to Alex Vesia and Edwin Diaz and the game came apart: Vesia recorded two outs and gave up 2 hits and 2 runs, and Diaz recorded two outs and gave up 2 hits, a home run and a run, pushing his ERA to 9.35. Chicago scored in the sixth, added 2 in the seventh and 1 more in the eighth.
The Cubs out-hit the Dodgers 9-4 in front of 40,584 at Wrigley. Dansby Swanson went 3-for-4 with a home run, 2 runs and an RBI. Nico Hoerner went 2-for-4 with a home run and 2 RBI. Pete Crow-Armstrong added 2 hits and an RBI. On the other side, Shohei Ohtani, Freddie Freeman and Tucker had all four Los Angeles hits between them while Mookie Betts, Max Muncy, Teoscar Hernandez and Tommy Edman went a combined 0-for-12.
The standings absorbed the result without much drama. Los Angeles fell to 69-45 and a five-game losing streak, still 9 games clear of Arizona in the National League West. Chicago improved to 65-49, second in the National League Central and 5.5 games behind Milwaukee at 70-43. The Cubs team hub and the Dodgers team hub carry the season-long market picture for both clubs.
The moneyline resolved to Chicago. Cubs contracts settled at 100c on both Kalshi and Polymarket and Dodgers contracts settled at 0c. The four-run margin carried the run line: Cubs -1.5, Cubs -2.5 and Cubs -3.5 all settled YES, while every Dodgers run-line contract settled at 0c or 1c. Six combined runs put the total under the 8.5 line on the board and under the 9.0 that sportsbooks posted. Player props settled off the same box score, with the Swanson and Hoerner home run contracts resolving YES and the Skubal over 5.5 strikeouts contract resolving YES on 6 punchouts.
The series finale trades on the August 5 Dodgers vs Cubs board, with Chicago leading the set 2-0 and Los Angeles trying to stop a five-game losing streak.

The moneyline market resolved to the Chicago Cubs, who beat the Los Angeles Dodgers 5-1 at Wrigley Field on August 4, 2026. Cubs contracts settled at 100c and Dodgers contracts at 0c on both Kalshi and Polymarket, with each winning share paying $1. Run-line contracts settled on the four-run final margin, so Cubs -1.5, Cubs -2.5 and Cubs -3.5 all resolved YES while every Dodgers run-line contract resolved NO. The total settled on six combined runs, under the 8.5 line carried on the board and under the 9.0 posted by sportsbooks. In-game derivative contracts settled off the same box score, including the tied-after-five-innings contract, which resolved YES at 1-1. Both platforms settle from the official final box score on the scheduled date; a postponement or a suspension before the game became official would have voided the contracts under each platform's rules, which did not apply here.
The Chicago Cubs won 5-1 over the Los Angeles Dodgers at Wrigley Field on August 4, 2026. Chicago out-hit Los Angeles 9-4 in front of 40,584 fans and took a 2-0 lead in the three-game series.
The Dodgers were a 66c favorite, 66c on Kalshi and 65c on Polymarket, with the Cubs at 36c. That implied roughly a 66% chance of a Los Angeles win, and DraftKings agreed at -186.
