A real two-leg NFL parlay, $20 stake
| Venue | Pays | vs best |
|---|---|---|
| Kalshi combo best | $57.80 | - |
| FanDuel | $54.64 | -$3.16 |
| BetMGM | $52.67 | -$5.13 |
| DraftKings | $52.36 | -$5.44 |
Kalshi: a live combo quote at $0.346 per $1 contract, before Kalshi's fees. Sportsbooks: stake times the product of each leg's decimal odds (FanDuel 1.74 and 1.57). A historical observation; no bet was placed. Prices move by the minute, which is why Combo checks them right before you bet.
How it works
Pick 2 to 6 legs from this week's NFL games: moneylines and totals first, spreads next.
A live combo quote from Kalshi, the prediction-market venues you use, and each sportsbook's payout from its leg odds.
You place the bet yourself, at the venue. Combo never takes bets and never asks for your sportsbook password.
Why this doesn't exist yet
Odds screens stop at sportsbooks. They compare single lines, and the ones that price parlays only cover sportsbooks. Prediction-market combos are quoted on request, so they appear in no odds feed.
The gap is real money. Parlays are where venues keep the most margin, and the same ticket can pay noticeably more at one venue than another. A few dollars on every ticket adds up over a season.
One record of what you made. Coming next: your results across Kalshi, Robinhood and the sportsbooks in one ledger, with a tax-ready export.
