“The odds for this fight were first released in November 2016 when it was still just a rumor,” said Joe Osborne, content manager for OddsShark, a sports gambling information site. McGregor started out about 9½-1.The lure of winning $9 or $10 for a dollar bet on McGregor seemed to be much greater than betting a huge amount to win a little on Mayweather. The McGregor money started coming in, and drove down his price, eventually to as low as 3½-1.Dave Mason, a spokesman for the wagering site Betonline.ag, said 89 percent of his book’s bets have been on McGregor.The McGregor bandwagon seems to be driven largely by smaller stakes gamblers. “Due to the odds being so lopsided, you need to bet big to win big on Mayweather,” Bridge said. “So larger wagers are being placed on him. But more individual wagers of smaller amounts have been placed on Notorious.” Mason said he thought the true odds on the fight should be more like 20-1. “I think we’re going to see the sharper bettors come in later,” he said.

it's a classic example of many gamblers wrongly believing that a large payout must have "value" and that a small payout cannot have "value."
Straight handicapping wise... Mayweather should be -2000 or more. -500, or even now -550, is a steal on Mayweather. If you can find a place that let's you bet $50k to win $10k, like an actual sports book, I'd take that bet all day every day thanks for the free $10k.
