Etymology

The word "arbs" comes from "arbitrage," which is a French word.

Think of "arbitrage" as meaning to "judge" or "decide." In financial terms, it's about making a judgment call on a price difference. The word "arbitrage" itself has been around since the 1700s, meaning the practice of buying something in one market and immediately selling it in another for a profit, because of a price difference.

"Arbs" is simply a shortened, informal, and more modern way of referring to two things:

1. The people who do arbitrage. So, instead of saying "arbitrageurs," people say "arbs." This use became common as financial markets grew more complex and specific roles emerged.

2. The opportunities themselves for arbitrage. Sometimes, people will refer to "finding arbs" when they mean finding opportunities to profit from price differences.

The exact first known use of "arbs" as this specific informal short form is a bit difficult to pinpoint precisely in historical records, as it's more of a slang term that would have emerged in financial trading circles. However, it gained prominence in the latter half of the 20th century, particularly as financial trading became more rapid and the need for quicker, more concise language among traders increased. It's an example of how specialized jargon develops within professional communities.
