What is arbitrage betting?

Definition
Arbitrage betting (an arb) is placing bets across multiple bookmakers on all possible outcomes of an event such that the combined return is positive regardless of which outcome occurs. The "edge" comes from price disagreements between books, not from edge against true probability.
Arbs are positive-EV by construction but face two problems: opportunities live for seconds (manual placement is hopeless), and consistently arbing the same books gets accounts limited. Sharps run arbs in moderation across many books; recreational accounts get limited fast. Glitch Edge doesn't ship an arb scanner — that's not the platform's focus — but the executor can run an arb-style strategy if the operator writes one.
Arb math
Two-way market with odds o_a at book A and o_b at book B. The arb exists if:
(1 / o_a) + (1 / o_b) < 1
The surplus below 1 is the guaranteed return. A 2-way market summing to 0.98 yields a 2% return regardless of outcome.
Why arbs limit accounts
Books detect arb patterns: small frequent stakes, consistent CLV-positive placement, betting opposites at different books. Recreational books limit; sharp books (Pinnacle, Cloudbet) generally don’t. The arb stack matters as much as the math.
