New York (81-62) is the home favorite over Colorado (55-88) at 75.5c on the blended board as of the morning of September 8, 2026, with Kalshi at 76c and Polymarket at 75c. The starting pitching is the reason the price sits where it does: Cam Schlittler carries a 2.04 ERA, second among qualified MLB starters, against Gabriel Hughes at 0-6 with a 6.19 ERA. The board has taken roughly $233K across both platforms, and the run line, not the moneyline, is where the real question lives.
Colorado opens a three-game set at Yankee Stadium on Tuesday, September 8, 2026, first pitch 7:05 PM ET, and the market treats it as the least competitive matchup of the Yankees' homestand. The Rockies are 55-88 with a run differential of minus 140, the worst mark in the National League, and they are 25-47 away from Coors Field. The Yankees are 81-62 and 37-31 at home. Roughly $233K has traded on this board across Kalshi and Polymarket, and both books agree on the shape of the game to within a cent on the moneyline.
New York sits at 75.5c on the blended board (76c Kalshi, 75c Polymarket), with Colorado at 25.5c (25c Kalshi, 26c Polymarket). That is a one-cent cross-platform gap on the most liquid leg of the board, which is agreement rather than a pricing dispute. The Yankees moneyline carries about $72.7K in lifetime volume between the two books and the Rockies side about $34.1K, so both legs are genuinely traded and neither price is a thin-book artifact.
Snapshot history on this board reaches back to roughly 8:06 PM ET on Monday and runs through 8:02 AM ET Tuesday morning. Over that 12-hour window the Yankees moneyline held a one-cent band: Polymarket sat flat at 75c on every capture, and Kalshi ticked from 75c to 76c. The run line moved slightly more. The Yankees at -1.5 opened the window at 57c on both platforms and finished it at 58c Kalshi, 59c Polymarket. That is the market nudging toward a multi-run New York win rather than a narrow one, and it is the only leg on the board that moved a meaningful amount overnight.
The run line is the more interesting number. New York -1.5 at 58.5c and New York -2.5 at 47.5c mean the market prices a three-or-more-run Yankees win at close to a coin flip. Against a 75.5c moneyline, that implies the market expects blowout distributions rather than close games: a favorite that wins 76% of the time but only covers -1.5 at 58% is being credited with a wide margin profile. The full-game total sits at 55c on the over 7.5 rung, identical on both platforms, with over 6.5 at 66c and over 8.5 at 46c, so the implied number is a hair under eight runs.
The widest cross-platform gaps on this board are in the home run props, not the sides. Aaron Judge to hit a home run trades at 25c on Kalshi and 22c on Polymarket, and Hunter Goodman to go deep is 17c Kalshi against 10c Polymarket. Those are thin-book rungs with a few thousand dollars behind them, so the disagreement reflects illiquidity rather than a genuine difference of opinion between two informed markets. The moneyline is where the money is and the moneyline agrees.
Cam Schlittler is 12-6 with a 2.04 ERA, second among MLB starters, and he is the single largest reason the Yankees are not priced closer to the mid-60s. The strikeout props reflect the profile: his over 7.5 strikeouts rung is 54c, ten-plus strikeouts sits at 24c, and twelve-plus is still live at 8c. A 24c price on double-digit punchouts against a lineup that has struck out at a high clip on the road is the board saying this is a plausible dominant start, not a fluke outcome.
Gabriel Hughes is 0-6 with a 6.19 ERA and the market prices him accordingly. His over 3.5 strikeouts rung is 61c, five-plus strikeouts is 41c, and six-plus is 24c, all well below Schlittler's equivalents. Colorado's team total tells the same story: the Rockies over 2.5 runs is 52c and over 3.5 is 37c, while the Yankees over 3.5 runs is 69c and over 4.5 is 56c. The board expects New York to score roughly a run and a half more.
The stakes are lopsided. New York is four games behind Tampa Bay (85-58) in the AL East and two clear of Boston (80-65) with 19 games to play, so every game against a 55-88 opponent is one the Yankees are expected to bank. Colorado has been eliminated from meaningful positioning for weeks and sits 33 games out in the NL West. The AL East division market is the board that actually prices what a Yankees win here is worth.
The moneyline resolves to the team that wins the game on Tuesday, September 8, 2026, at Yankee Stadium, first pitch 7:05 PM ET. Kalshi and Polymarket both settle once the game goes final, typically within minutes of the last out. The spread rungs settle on the final margin and the total rungs on combined runs scored by both teams. A suspended or postponed game carries over to its official completion date under each platform's rules, and a game called before it becomes official is voided.
This is the opener of a three-game set, and the two follow-ups are already trading: Wednesday's game and Thursday's finale both carry cross-platform boards, with New York priced lower in each as the pitching matchup narrows. The season-long picture lives on the AL East division board and the NL West board.

The moneyline resolves to the team that wins the game played at Yankee Stadium on Tuesday, September 8, 2026, scheduled for 7:05 PM ET. Winning contracts pay $1 per share and losing contracts settle at $0. Spread contracts settle on the final margin of victory and total contracts settle on combined runs scored by both teams, including any extra innings. Kalshi and Polymarket both settle from the official MLB final score once the game is complete. If the game is postponed or suspended, it settles on the official completion date under each platform's rules; if it is called before reaching official status and is not resumed, the contracts are voided and stakes returned.
As of the morning of September 8, 2026, New York is the 75.5c favorite on the blended board (76c Kalshi, 75c Polymarket) and Colorado is 25.5c (25c Kalshi, 26c Polymarket). The live board above carries the current prices.
The Yankees are favored at roughly a 76% implied probability. New York is 81-62 and 37-31 at home; Colorado is 55-88 and 25-47 on the road.
Both Kalshi and Polymarket list this game. The board has taken about $233K in lifetime volume across the two platforms, with the moneyline, run line, total, first-five markets and player props all live.
It resolves when the game goes final at Yankee Stadium on Tuesday, September 8, 2026, first pitch 7:05 PM ET. Both platforms settle from the official MLB final score, usually within minutes of the last out.
The primary run line is New York -1.5 at 58.5c, with New York -2.5 at 47.5c. The full-game total is priced at 55c on over 7.5 runs, identical on both platforms, implying a number just under eight runs.
Watch the run line rather than the moneyline. New York -1.5 moved from 57c to 58c on Kalshi and 59c on Polymarket between Monday evening and Tuesday morning while the moneyline held a one-cent band, so the margin market is where the late money has been going.
