What is arbitrage betting?
An arbitrage (“arb”) is when two books price the same event differently enough that betting both sides guarantees a profit. When the two implied probabilities add up to under 100%, the edge exists — you just split the stake in the right proportion. Real arbs open and close in seconds across dozens of books.
