Circa Sports does not charge commission on top of its prices; its margin sits inside the odds. That makes it a useful reference for fair prices, and the calculators on this page compare it with exchanges that do charge.
Circa Sports is a Las Vegas bookmaker known for low margins and for accepting sharp action. Like Pinnacle it charges no commission and serves as a reference line for US markets.
How Circa Sports commission works
With no commission, the price you see is the price you get. Compare it directly with an exchange's effective odds after commission to decide where to bet.

Backing at a bookmaker, laying at Circa Sports
Circa Sports does not offer lay bets, so the usual bookmaker-versus-exchange hedge is not available. Two-way arbitrage still works by backing one outcome at Circa Sports and the other at a bookmaker; the calculator above is set up that way, with Circa Sports's commission on its leg.
Using Circa Sports prices to find fair odds
Exchange prices are set by traders rather than by a bookmaker's margin, so after commission they are often close to the fair line. To use them that way, take both sides of a market, remove what little overround remains with the devig calculator pre-set to Circa Sports, and compare the result with the bookmaker prices you are offered. A bookmaker price above the fair line is value.
Comparing Circa Sports with other venues
The pairs listed at the bottom of this page each open an arbitrage calculator with Circa Sports on one leg and another venue on the other, commission applied to both. They are the quickest way to see how much two venues must disagree before a position pays.

Frequently asked questions
Can I lay bets at Circa Sports?
No. Circa Sports does not offer lay bets, so hedges against a bookmaker use a back bet on the other outcome instead.
Is Circa Sports a good source of fair odds?
Prices set by traders carry a small overround, so after removing it they are close to a fair line. Remember to account for commission when comparing with a bookmaker price you will actually take.
Does commission apply to every bet?
Most venues charge on the net result of a market rather than on each bet, so offsetting bets in the same market share one commission charge. This site models one bet at a time.
