Colorado was close to .500 for a month. The Rockies went 13-14 in April and stood at 14-18 on April 30. May broke the season: an 8-20 month left them at 22-38. They then went 11-15 in June, 10-14 in July and 9-19 in August, reaching 54-87 on September 4 with 21 games left.
Colorado beat the White Sox 9-6 the next day and lost the finale 4-2.

Prices are bid/ask midpoints, since most of these hours had no trade. The in-season rows use noon ET because home games at Coors Field often ran past Kalshi's midnight ET close.
For most of the summer the price rose while the Rockies kept losing, because 60 wins asked so little. It climbed to 88% in early September. At that point the Rockies needed six wins in 21 games, a .286 pace from a team playing about .380 ball. They went 4-17. The eight-game skid took the contract from 88% to 54.5%. It sat at 40.5% on the morning of September 19, and after that night's win, four straight losses took it to 5% by the morning of September 25. The preseason center was close to the final count; the September collapse was the outlier.
No 2027 win-total ladder is listed on Kalshi or Polymarket as of October 16, 2026. Kalshi opened the 2026 ladder on December 16, 2025, more than three months before Opening Day, so a 2027 Rockies line would follow the same offseason calendar.
The division finish is on the resolved 2026 NL West market, won by the Dodgers, whose own win total ladder settled on 100 wins. Colorado did not have the majors' worst run differential: the Athletics posted -238, and their 2026 win total market resolved Under on every line. The 2026 World Series market is still live, and the Colorado Rockies hub collects every Rockies board.
Kalshi's ladder asked whether the Colorado Rockies would win at least N games (35, 40, 45, 50, 55, 60 or 65) in the 2026 regular season; each rung resolved Yes at N or more wins, ties did not count as wins, and postseason games did not count. Polymarket's line resolved Over if the Rockies won more than 65.5 regular-season games, resolved Under early if that became statistically impossible, named official MLB standings as the source, and would have resolved 50-50 if the season were cancelled, left incomplete or postponed past November 30, 2026. Kalshi settled each rung as it was decided, the 65-win rung No at 1:09 a.m. ET on September 19 and the 60-win rung No at 12:06 a.m. ET on September 26, 2026; Polymarket closed its line at 9:38 p.m. ET on September 17, 2026, and resolved it Under.
The Colorado Rockies finished the 2026 regular season 58-104, 15 wins better than their 43-119 record in 2025 and their fourth straight season with at least 100 losses.
Kalshi settled its 35 through 55-win rungs Yes and its 60 and 65-win rungs No, with the 60-win rung settling at 12:06 a.m. ET on September 26, 2026. Polymarket's over-65.5 line closed on September 17 and resolved Under.
Kalshi's 60-win contract was quoted at 88% at noon ET on September 5 with Colorado at 54-87. It fell to 40.5% by September 19 and to 5% on the morning of September 25.
Colorado went 4-17 over its last 21 games, including eight straight losses from September 6 to 14 and four more from September 20 to 24, and a 6-1 loss to the White Sox on September 25 made 60 wins impossible.
