The Dodgers are the 65.5% favorite in game 3 of this four-game set at Great American Ball Park, first pitch 6:40 PM ET, with Kalshi at 66% and Polymarket at 65% on Los Angeles. A one-point gap between venues leaves no arbitrage on the moneyline, so the disagreement worth trading sits one rung down the board. Los Angeles is 92-59 and leads the NL West; Cincinnati is 70-81 and sits fifth in the NL Central, and the board has cleared roughly $11.5K across both platforms with the Dodgers moneyline leg alone carrying about $9.0K of it.
Los Angeles prices at 65.5% on the cross-platform average, 66% on Kalshi and 65% on Polymarket. Cincinnati is the 35.5% side, 35% on Kalshi and 36% on Polymarket. Both legs are verified two-book pairs, and a one-point spread between venues is a market that agrees with itself. The two sides also do not sum to 100, which is the ordinary vig on a Kalshi binary, not a pricing error.
The records support the price rather than argue with it. The Dodgers are 92-59 overall and 45-31 on the road, first in the NL West. The Reds are 70-81 and, more to the point for a home game, 36-40 at Great American Ball Park. A road team that wins 59% of its road games against a home team that loses more than it wins at home is a fair 65.5% favorite before anyone looks at the starters.
Blake Snell is listed as the probable starter for Los Angeles as of September 15, carrying a 4-1 record and a 1.91 ERA. Cincinnati is listed to counter with Andrew Abbott at 6-11 and a 4.78 ERA. That is the widest starter ERA gap in the series and it is the reason the Dodgers price sits nearer two thirds than a coin flip. Probables are listed, not confirmed, so treat the names as the current card rather than a settled lineup.
The totals board does not follow the starter gap. The match total Over 8.5 runs prices at 51.5% (52% Kalshi, 51% Polymarket), a true pick, with Over 7.5 at 58.5% and Over 9.5 at 40.5%. The market is not pricing Snell to suppress this game to a 6-run affair.
The run line is the cleanest read on the board. Dodgers -1.5 trades at 53.5% (54% Kalshi, 53% Polymarket), so the market gives a two-run-or-better Los Angeles win almost the same probability it gives a Los Angeles win of any margin minus a dozen points. Reds -1.5 is 21.5% (22% Kalshi, 21% Polymarket). The first five innings carry their own set: Dodgers -1.5 through five at 43% on both books, Reds -1.5 through five at 18.5%, and the first-five total Over 4.5 runs at 46%.
One cross-platform gap is worth flagging. Over 7.5 runs scored prices 60% on Kalshi against 57% on Polymarket, a 3-point split on a full-game total that both venues quote. Polymarket has the better number for an over buyer and Kalshi has the better number for an under. Note that the deep rungs are not symmetric coverage: the Over 10.5, Over 11.5 and Over 12.5 rungs, every team total, and both -3.5 spreads are Kalshi-only prices with no Polymarket counterpart, while the three-way winning-after-five-innings market (Dodgers 56%, Reds 27%, tied 13%) is Polymarket-only. Those are single-venue quotes, not consensus, and should be read as one book's opinion.
The board's snapshot history on this game covers roughly one hour of captures on the evening of September 15, from about 8:07 PM ET to 9:07 PM ET, so this is an opening read and not a full session. In that window Los Angeles held at 66% on Kalshi across four consecutive captures and 65% on Polymarket, while the Cincinnati leg ticked from 36% to 35% on Kalshi. Volume behind the Dodgers leg grew from about $7.6K to $7.8K over the same hour. Nothing on the run line or the totals carried snapshot history at all, so there is no movement claim to make there. More of the series context is on the September 15 game page and the rest of the day's card is on today's slate.
At 65.5% the Dodgers are priced roughly where a first-place team starting a 1.91 ERA arm against a sub-.500 home club belongs, so the moneyline is not the trade. The two spots that are: the 3-point venue disagreement on Over 7.5 runs, and the run line at 53.5%, which asks whether a Snell start turns into a two-run-plus margin or a one-run game. The Reds at 35.5% are not a value play on form; they are a bet that Abbott's 4.78 ERA overstates the gap on one night. Full MLB market coverage tracks the rest of the league board.
The moneyline resolves to the team that wins the game outright on the final score, with no push outcome available. The spread markets settle against the final margin (Dodgers -1.5 pays if Los Angeles wins by two runs or more), and the total markets settle on combined runs scored by both teams across the full game, with the first-five-innings variants settling on the score after five complete innings. Settlement occurs on both Kalshi and Polymarket once the game at Great American Ball Park on September 16, 2026 goes final, typically within a few hours of the last out. A postponement moves settlement to the rescheduled date; a game called early is resolved by each platform's official-game rules.
As of the evening of September 15, 2026, the Los Angeles Dodgers price at 65.5% on the cross-platform average (66% on Kalshi, 65% on Polymarket) and the Cincinnati Reds at 35.5% (35% on Kalshi, 36% on Polymarket). The live board above carries the current numbers.
The Dodgers are favored at an implied 65.5% win probability, roughly a 30-point edge over Cincinnati at 35.5%. Los Angeles enters 92-59 and 45-31 on the road; Cincinnati is 70-81 and 36-40 at home.
Both Kalshi and Polymarket list this game. Kalshi carries the moneyline, spreads, match and team totals, first-five-innings markets and a run-in-the-first-inning market. Polymarket carries the moneyline, the main spreads and totals, and a three-way winner-after-five-innings market.
Dodgers -1.5 on the run line prices at 53.5% and Reds -1.5 at 21.5%. The match total Over 8.5 runs sits at 51.5%, Over 7.5 at 58.5% and Over 9.5 at 40.5%, pricing this as a mid-to-high scoring game at Great American Ball Park.
First pitch is 6:40 PM ET on September 16, 2026 at Great American Ball Park, and both platforms settle once the game goes final, usually within a few hours. This is game 3 of a four-game series that closes on September 17.
