What the market says
The Athletics have the better season, 62-95 against the Angels at 60-97, and the market still makes the Angels the favourite at 55¢. Home field, the starters and who is rested are all in that number and none of them are in a win-loss record. When the two disagree this plainly one of them is wrong, and this page does not know which.
| Side | Record | Bid / ask | Last | Contracts traded |
|---|---|---|---|---|
| Angels | 60-97 | 54¢ / 55¢ | 55¢ | 28,516 |
| Athletics | 62-95 | 45¢ / 46¢ | 46¢ | 10,581 |
Kalshi series KXMLBGAME, event 26SEP232140LAAATH, read Wed, Sep 23, 2026, 5:20 AM PT.1 You pay the ask to buy and take the bid to sell, so a round trip costs more than one column suggests.
Run the numbers
These are the prices we read at Wed, Sep 23, 2026, 5:20 AM PT, not numbers we typed in. Pick a stake and the panel counts the contracts it buys at 55¢, the fee on the way in, what a sell at your target returns if it fills, and what the whole position costs if Angels lose. Nothing here places an order and nothing is saved.
Reading the price
A contract pays $1.00 if that side wins and nothing if it loses, so the price is the crowd’s probability with the house’s cut on top. At 55¢, the crowd says 55% on Angels. At 46¢ it says 46% on Athletics.
Those two add to 101%, not 100%. The extra 1 points are the spread between buying and selling, and it is what the market charges to take either side. It is the first thing to subtract before deciding a price is cheap.
Walbert Ureña starts for Angels and Jeffrey Springs for Athletics. A starter is the single biggest thing in a one-game price, which is why a team can be better all season and still be the underdog tonight.
How we grade
If the desk posts a call on this game it goes up before first pitch with the buy price, the sell target and what happens if the target never fills, and it is graded on Kalshi’s own trade history with both fee legs counted, win or lose. A miss stays on the record next to the wins. How we lock and grade
