Bookmaker Coverage — Sportsbooks in the Live Arbitrage Feed

Why bookmaker coverage drives arbitrage quality

Arbitrage opportunities exist because two bookmakers disagree about the probability of the same outcome. A scanner that ingests N bookmakers can compare N × (N-1) / 2 bookmaker pairs — so coverage grows the opportunity surface quadratically. Going from 10 books to 100 books doesn't find 10× more arbs; it finds roughly 100× more price comparisons to check, which is why the live scanner surfaces new opportunities on every 30-minute refresh.

Coverage breadth also matters for the quality of the value bets feed: the consensus probability for each outcome is computed across all books in the feed, so a broader feed produces a more reliable "fair" price to measure overvalue against.

Two ingestion pipelines, one feed

The OddsFetcher feed combines two independent odds pipelines so coverage doesn't depend on a single upstream provider:

• Surebet.com pipeline — scans arbitrage opportunities across the widest bookmaker universe, including regional and international books (Cloudbet, Efbet, Betcity, Leon, PointsBet AU and many more) that rarely appear in English-language review roundups. Runs every 30 minutes.
• The Odds API pipeline — ingests odds from the major licensed sportsbooks (DraftKings, FanDuel, BetMGM, Bovada, BetOnline.ag and others) twice daily, powering the value-bet detection and the editorial bookmaker reviews.

How to use this page

1. Check a book is in the feed before you rely on it. If a sportsbook you hold an account with isn't listed, the scanner can't price arbs against it — open accounts at books that appear high in the table (they provide the most arb legs).
2. Prioritize accounts at the most active books. Books with high "arb legs" counts disagree with the market most often — those are the accounts that let you actually act on what the scanner finds.
3. Use best-arb % as a volatility signal, not a bonus. Very high best-arb percentages on niche books usually mean slow-moving odds, not free money — verify the price at the book before staking, and read the arbitrage betting guide first.

Frequently asked questions

Which bookmakers does OddsFetcher track?

The live feed currently ingests odds from 101 bookmakers, including Cloudbet, Efbet, Naijabet, Leon, Veikkaus, Maxline, Betcity, Cbet and many more regional and international sportsbooks. The full list on this page is generated live from the feed — it updates every time the scanner refreshes.

How often is bookmaker coverage updated?

The underlying odds ingestion runs every 30 minutes, so the coverage list, opportunity counts and best-arb percentages on this page always reflect the latest scan. Bookmakers can appear or drop out of a given scan depending on which events are live, but the core universe of 100+ books is stable.

Why does coverage matter for arbitrage betting?

Arbitrage opportunities exist because bookmakers disagree on price. The more books a scanner ingests, the more price disagreements it can catch, and the better the arbs. A scanner that only covers a handful of books misses most opportunities — that is why OddsFetcher ingests 100+ bookmakers across two independent odds pipelines.

Is the bookmaker list on this page live or hand-written?

Live. Every bookmaker, count and percentage on this page is computed from the same ingested feed the arbitrage scanner uses — nothing is hand-maintained. If a bookmaker stops appearing in the feed, it drops off this page on the next refresh.

How is this different from the bookmaker reviews page?

The bookmakers review page is an editorial ranking of the major licensed sportsbooks with ratings, bonuses and payout speeds. This page shows the actual bookmaker universe inside the live odds feed — including regional and international books that rarely appear in review roundups but frequently offer the best arbitrage prices.
