ⓘ +2.1% gold badge = that best price beats the de-vigged Pinnacle fair line by 1.5% or more (every one is tracked on +EV Plays). % hold = what the market keeps: the two best moneyline prices' implied probabilities minus 100. A green negative hold means the best prices sum under 100%, so betting both sides locks a small profit.
ⓘ The dot on a Kalshi, Polymarket US, ProphetX or Novig badge is how much money is really behind that price, measured the same way we price it (what a $100 bet fills at). Green means $1,000 or more is available at that price. Amber means $100 to $1,000, so a bigger bet will move it. Red means under $100, less than the $100 we price at. Those prices sit at the bottom of All Books for information only: they are never ranked as the best price and never go on the bet slip. Gray means we could not measure it. Tap the badge for the exact figure. A sportsbook price carries no dot because a sportsbook is not an order book: it takes your bet at the posted price up to its limit, and there is no book to measure.
ⓘ Kalshi & Polymarket US prices on this page include each venue's trading fees. They show what a taker actually pays. How we calculate this →

How The Odds Gap Finds Your Edge

Same bet, better price. We do not sell picks. We do the arithmetic that tells you which book is paying the most for the exact bet you were going to make anyway.

1

We Pull Every Book's Price

Live odds from every major sportsbook and prediction market, side by side, refreshed through the day so the number you see is the number that is up.

2

We Find the Sharpest Line

Pinnacle and the prediction markets set the fair price. We strip out the built-in margin (the vig) to see what each side is really worth, with no juice baked in.

3

We Surface the Gap

When one book drifts off that fair number, that difference is value you can capture. We show you the best price and exactly how much better it is than the next book.

Math, not picks. Learn the concepts on Learn, or read the full methodology.
