Washington is the 58c moneyline favorite for Wednesday's game three at Nationals Park, quoted 59c on Kalshi and 56c on Polymarket, with Colorado at 43c. The records carry the price: the Nationals are 62-72, the Rockies 51-81 and 24-43 on the road behind a 5.59 team ERA that ranks last in the majors. Colorado sends Tanner Gordon (0-4, 5.75 ERA) and won game two 3-1 to level the series at 1-1. The live board above shows both books.
Colorado at Washington is game three of a four-game set at Nationals Park, and the series is tied 1-1 after the Nationals took the opener 13-3 and the Rockies answered 3-1. Washington enters 62-72. Colorado enters 51-81, including 24-43 on the road, and carries a 5.59 team ERA that ranks last in the majors. First pitch is 6:45 PM ET on Wednesday, August 26, 2026, a time confirmed independently by the Kalshi event ticker (KXMLBGAME-26AUG261845COLWSH) and the ESPN scoreboard. The board trades on both Kalshi and Polymarket with roughly $640 in lifetime volume, which is thin even by daily-game standards.
Rockies vs Nationals Market Context
Washington is the favorite on both books, and the two disagree by 3c. As of the evening of August 25, Kalshi has the Nationals at 59c and the Rockies at 42c, a two-sided sum of 101c that reflects the exchange's vig. Polymarket has the Nationals at 56c and the Rockies at 44c, summing to exactly 100c. That makes Polymarket the better entry on Washington and Kalshi the better entry on Colorado. The live board above carries the current numbers on both platforms.
The gap is a liquidity story rather than a disagreement about the baseball. Kalshi holds $426 of lifetime volume on the Nationals side against $11 on Polymarket, so Kalshi is doing the price discovery and the Polymarket quote is a thinly traded mirror of it. Read the Kalshi number as the market's opinion and the Polymarket number as an execution detail.
The snapshot series on this board reaches back about two hours as of publication, with captures running from 8:17 PM to 10:13 PM ET on August 25. Across those readings the Kalshi Nationals line printed 59c every time and the Polymarket line printed 56c every time, so nothing has moved inside the window we can observe. That is a claim about two hours of history and not about the full life of the market: this board opened recently and does not carry a longer series yet.
One outside reference point is worth flagging. ESPN's matchup predictor puts Washington at 65.2%, roughly seven points above the 58c cross-platform consensus. Models of that type lean on season-long team quality and are slow to adjust for an unannounced starter, which is exactly the information this market is missing.
What the Rockies vs Nationals Pitching Matchup Implies
Colorado's listed starter is Tanner Gordon, who carries an 0-4 record with a 5.75 ERA and a 1.49 WHIP across 78.2 innings, with 16 home runs allowed against 64 strikeouts. ESPN lists his position as relief pitcher, which is the Rockies season in one line: a 5.59 staff ERA, last in baseball, and a rotation held together with bullpen arms. Washington had not posted a probable starter as of publication, and that missing input is a real part of why the price sits at 58c instead of higher.
Washington's offense is why the number is not lower still. The Nationals have scored 695 runs, a total ESPN ranks at the top of the league, on a .249 team average. CJ Abrams is carrying the lineup with a .276 average, 29 home runs, and 92 RBI. The counterweight is run prevention: a 4.67 team ERA that ranks 26th and 90 errors, the most in baseball. Colorado is barely better in the field with 86 errors, 29th. Two of the sloppiest defenses in the sport meeting in a park with gusts to 17 mph and an 85 degree first pitch argues for variance, and variance is what keeps a 51-81 road team priced at 43c instead of 30c.
Neither club is playing well. Both are 1-4 over their last five games, and each of those wins came in this series. Availability matters on the margins. Washington is without James Wood (10-day IL) plus Josiah Gray and DJ Herz (60-day IL), while Colorado has Ezequiel Tovar day-to-day, Kyle Karros on the 7-day IL, and Kyle Freeland on the 15-day IL. Hunter Goodman (35 home runs, 70 RBI) is the Rockies bat that travels, and a warm night in Washington suits him. The full slate of Colorado markets sits on the Rockies hub, and Washington's on the Nationals hub.
The board also carries a first-inning market, priced at 47c on both Kalshi and Polymarket, on whether either team scores in the opening frame. That one has traded about $1 of lifetime volume, so treat the 47c as a posted quote rather than a crowd view.
When the Rockies vs Nationals Market Resolves
The moneyline settles the night of Wednesday, August 26, 2026, once the game goes final at Nationals Park. The winning team's contract pays $1 per share and the losing side settles at $0. Baseball has no draw, so a tie after nine innings simply extends the game until a winner is decided. The first-inning contract resolves as soon as the top and bottom of the first are complete. Both platforms settle from the official Major League Baseball result, and a postponement carries the contract to the makeup date under each platform's published rescheduling rules.
Key Rockies vs Nationals Catalysts
- Tanner Gordon's length: Colorado's starter carries a 5.75 ERA and a 1.49 WHIP, and a short outing hands the game to a bullpen that has already blown through a 5.59 staff ERA.
- Washington's unannounced starter: the single largest missing input in the 58c price, and the most likely reason the line moves before first pitch.
- The 3c cross-platform split: Washington is 59c on Kalshi and 56c on Polymarket, so the side you want dictates the venue you use.
- CJ Abrams: a .276 hitter with 29 home runs and 92 RBI against the worst staff ERA in the majors is the cleanest edge on the card.
- Defense: Washington's 90 errors lead baseball and Colorado's 86 rank 29th, which is the variance that keeps a 51-81 team at 43c.
- Injuries: James Wood is on the 10-day IL for Washington and Ezequiel Tovar is day-to-day for Colorado.
Related Rockies vs Nationals Markets
Both of these clubs are playing out a season already decided, and the futures boards price that directly. The Nationals playoff market and the NL East winner market both treat Washington as long since eliminated from contention, while the Rockies season win total is the live question for a 51-81 club with a month left.

Resolution Criteria
Resolves to the team that wins the game outright at Nationals Park on Wednesday, August 26, 2026, first pitch 6:45 PM ET. The winning team's contract pays $1 per share and the losing team's contract settles at $0. Major League Baseball has no draw outcome, so a game tied after nine innings continues until a winner is decided, and extra-inning results settle the moneyline normally. The separate first-inning market resolves YES if either team scores at least one run in the top or bottom of the first. Both Kalshi and Polymarket settle from the official Major League Baseball final. If the game is postponed, each platform follows its published rescheduling rules, which carry the contract to the makeup date when the game is completed within the series window and void it when it is not played.
Key Factors
- Tanner Gordon (0-4, 5.75 ERA, 1.49 WHIP) and whether Colorado gets length from a starter ESPN lists as a reliever

- The 3c cross-platform split on Washington (59c Kalshi, 56c Polymarket) and which venue fits each side

- Defense as a variance source: Washington's 90 errors lead baseball, Colorado's 86 rank 29th
