View all sports →Right now the feed shows 2 live opportunities in 2 competitions, priced across 4 bookmakers, with the best returning 1.00%. These are Baseball opportunities from across the sport — no MLB arb is priced at the moment, but the wider Baseball markets are active.
The most common market type in the current feed is goals & totals, appearing in 2 opportunities. These are counted directly from the outcome labels the feed returns on each arbitrage leg, so the figures below reflect the markets bookmakers are actually pricing right now rather than a fixed list.
Baseball arbs concentrate in the moneyline, run line and total markets. The structural detail to check is whether the books are quoting the same market definition — a moneyline that includes extra innings is not directly comparable to one that books to the end of regulation. Once both legs settle on the same definition, the arbitrage calculation is standard.
The test is always the same regardless of sport: take the implied probability of every outcome you intend to back (1 ÷ decimal odds for each), add them up, and look at the total. Anything under 1.00 is an arbitrage, and the gap tells you the return before you place a single bet. OddsFetcher runs that comparison across every bookmaker in the feed continuously, so the opportunities listed at the top of this page are the ones where the total is genuinely below 100%.
Working out where to put the money is the practical next step. Each leg needs a stake proportional to its implied probability, and the free arbitrage calculator does that split for you from a total bankroll figure. If you would rather understand the arithmetic first, the sure bet calculation guide walks through two-way and three-way markets with worked examples, and the arbitrage betting guide covers how opportunities get created in the first place.
Not all baseball opportunities appear on this page at the same moment. Bookmakers reprice constantly, so the feed turns over throughout the day. To see every sport at once, use the live arbitrage scanner, or sure bets finder for a dedicated view. Single-outcome markets where one book's price is sharper than the consensus are listed separately under value bets.

This page is scoped to MLB, so the opportunities listed are the ones priced for MLB specifically. When no MLB arb is live, that is a temporary gap in the feed rather than an absence of MLB arbitrage — bookmakers reprice continuously, and the wider Baseball markets are shown on the Baseball page in the meantime.
Convert each decimal price to its implied probability by dividing 1 by the odds, then add those probabilities together across every leg you are backing. If the total is below 1 — for example 0.98 — you have an arbitrage, and the guaranteed return is (1 ÷ 0.98) − 1. The stake for each leg is proportional to its implied probability, so a MLB three-way market needs three separate stakes. The arbitrage calculator on this site does this for any set of prices automatically.
Comparing prices at different bookmakers is legal wherever sports betting is licensed, and an arbitrage is genuinely risk-free in theory — the profit is locked in before you place the bets. It is not risk-free in practice: you need an account at every bookmaker you back, the prices can move between finding an arb and placing the bet, and minimum-bet or stake-limit rules can prevent a full stake split. Most arbers also treat the profit as small and compound slowly rather than a large income.
