They don't. If it's under a certain amount, they don't investigate. They refund your money, send you a new card and write off the loses. It's far cheaper and quicker than investigating for a measly $500(from their perspective). They only investigate when fraud happens in the thousands of dollars.

They don’t investigate because it’s not their money to lose. Fraudulent charges for online (card not present) transactions end up being covered by the merchant who accepted the card, the banks don’t cover anything in that case.

Can merchants use insurance to guard against this, or would that just increase the expected value of their losses even more (in exchange for turning a variable cost into a fixed cost)?

It's mostly used by larger merchants, but there are services that do essentially that. The services analyze the transaction and will approve/deny it based on fraud risk. Denied transaction they won't cover if a 'chargeback' occurs.

The cost is usually a fixed percentage of the transaction, usually ~1% but can be higher and lower depending on the risk level of the industry.
