Top Kalshi MLB Picks Today: Stokastic Sims Vs The Market
Every morning, Stokastic's simulation engine plays out the day's MLB slate thousands of times, the same engine behind our DFS projections. Every day, Kalshi's traders price the same games and the same home run hitters in cents on a regulated exchange. This page puts the two next to each other and highlights where they disagree, then grades every published call against settlement, in public, the next day.
The Quick Answer
Kalshi prices MLB game winners and player home run contracts in cents, and a cent reads as a percentage point of probability. Stokastic's Sims produce their own probabilities for the same events from simulated at-bats, not from odds. Where the two agree, the market is probably right. Where they split by several points, one of them is wrong, and that is worth knowing about before first pitch. Today's game board, the top home run gaps, and the graded record are below.
Today's Games: Sims Runs Vs Market Price
The Sims do not output a team win percentage, so we do not invent one. What they do produce is a projected run total for every team on the slate, built from simulated lineups against tonight's actual starters. This board shows the projected run edge next to Kalshi's two-sided game price, and flags where the run edge and the market lean point at different teams.

| Game | Sims Projected Runs | Kalshi Price | Sims Lean | Market Lean | |
|---|---|---|---|---|---|
| ATL vs NYY | ATL 4.1 — NYY 4.6 | ATL 70c / NYY 30c | NYY | ATL | disagrees |
| NYM vs PIT | NYM 4.0 — PIT 4.5 | NYM 100c / PIT 0c | PIT | NYM | disagrees |
| BAL vs TEX | BAL 4.1 — TEX 4.4 | BAL 92c / TEX 8c | TEX | BAL | disagrees |
| ATH vs BOS | ATH 4.1 — BOS 5.6 | ATH 18c / BOS 82c | BOS | BOS | agrees |
| TOR vs PHI | TOR 3.7 — PHI 5.1 | TOR 4c / PHI 96c | PHI | PHI | agrees |
| MIN vs MIL | MIN 3.0 — MIL 4.4 | MIN 12c / MIL 88c | MIL | MIL | agrees |
| CHC vs KC | CHC 6.0 — KC 4.7 | CHC 82c / KC 18c | CHC | CHC | agrees |
| COL vs STL | COL 4.4 — STL 5.2 | COL 16c / STL 84c | STL | STL | agrees |
| LAA vs MIA | LAA 4.1 — MIA 4.6 | LAA 0c / MIA 100c | MIA | MIA | agrees |
| CLE vs CWS | CLE 4.6 — CWS 4.1 | CLE 66c / CWS 34c | CLE | CLE | agrees |
A disagrees row is not a pick to hammer; it is the day's most interesting question. Sometimes the market knows something the lineup sheet does not, a scratch, a bullpen day, weather. Sometimes the Sims see a matchup the price has not caught up to. The graded ledger settles who was right, one row per day.
Today's Top Home Run Gaps
This is the sharper edge of the page, because here the Sims produce exactly the number the contract asks about: the probability that a specific hitter goes deep today. Kalshi's 1+ home run contracts price the same event in cents. The five biggest gaps, in either direction:
Fetched August 9, 2026 at 3:34 PM ET.
| Hitter | Team | Sims HR% | Kalshi 1+ HR Mid | Gap |
|---|---|---|---|---|
| Jake Mangum | PIT vs NYM | 3.0% | 99.5c | -96.5 |
| Starling Marte | KC vs CHC | 7.1% | 99.5c | -92.4 |
| Jake Bauers | MIL vs MIN | 9.9% | 99.5c | -89.6 |
| Jose Siri | LAA vs MIA | 11.0% | 99.5c | -88.5 |
| Brooks Lee | MIN vs MIL | 11.3% | 99.5c | -88.2 |
A positive gap means the Sims like the homer more than the market does; a negative gap means the market is paying for a home run the Sims do not project at that rate. The full board of every Kalshi-listed hitter runs every day alongside this page.
The Record, In Public
Graded to date: 1 of 7 published HR gaps settled the way the gap pointed. Every graded call lives on the Sims vs Kalshi ledger.
Why we grade in public: anyone can publish picks. The only way a projection-versus-market page means anything is if every published gap gets settled against the exchange's own result and stays on the record, the misses included. That is what the Sims vs Kalshi ledger is for.
How To Read A Kalshi Price
If exchange contracts are new to you: a yes contract at 40 cents pays $1.00 if the event happens, so the market is charging you like a 40% chance. Both sides trade, so 40c yes implies 60c no. The spread between bid and ask is the cost of crossing the book, usually a few cents on these markets, and it is the house edge that actually exists here. Our sister site's guide to how to bet sports on Kalshi covers the mechanics end to end.
Built From The Sims
Every number in the tables above comes from the Stokastic MLB Sims, the projection engine our DFS subscribers build lineups with: simulated at-bats against tonight's real starters, park and lineup context included, refreshed as lineups confirm. If you want the projections themselves, not just the gaps, the Sims are the product, and the daily MLB DFS picks page shows the same engine pointed at DraftKings slates.
