Common questions2 questions

What margin does Circa Sports build into its prices?

Across 195 two-way NBA game line markets at the close (Oct 20 to Oct 28, 2026), the average margin was 4.40%. That is the two implied probabilities added together, minus 100%.

Can I bet through Dynatyze?

No. Dynatyze is research, not a sportsbook. We read prices and link you to the book; you place the bet there.

How this is read

Best price is a contest among US-licensed sportsbooks only. A side counts when at least 3 of them priced it at the same line; ties count for every tied book. Reference books, exchanges, offshore books and pick'em apps never compete for best.

Margin is the two implied probabilities of a two-way market added together, minus 100%, averaged over every market the book priced on both sides at one line.

NBA spreads, totals and moneylines: Each book's last quote before tip-off. 68 games, Oct 20 to Oct 28, 2026.

A market is listed once a book has 200 contested prop sides or 100 two-way prop markets in it (100 and 50 for game lines).

Arbs, middles and low holds are every one our scanner first saw from Sep 30, 2026 to Oct 27, 2026 that has since ended, under the desk's 8% ceiling, a book counted once per event it was a leg of. Four weeks, because the arb ledger keeps every sport whole for about 30 days. Life is the time from the first scan that saw an arb to the last, and scans run about a minute apart.
