Sample prices, for illustration.

Watch the cut come off.

Both sides of a bet should add to 100%. A sportsbook’s prices add to more, and the extra is its cut. Take it out and what’s left is the fair price. Beat that, and the bet is worth more than it costs.

Exchanges, in their own units.

Novig and ProphetX show a percentage. Kalshi shows a payout multiplier. GameFile prints both, with the fees taken back out, so the number matches the app when you place the bet.
