This is a major player, and I’m pretty sure they’re compliant with the law.
I often see this company because of their partnership with the LA Lakers and Clippers, they even named their arena Crypto.com Arena.
They can try to compete with Polymarket, but the market is huge, so I think their impact on Polymarket will be minimal.
They are not even trying to compete with polymarket since crypto.com is fully centralized fintech with an extra gambling feature that accept US players while Polymarket is not allowed to accept US player.
They have different market so I think they are just riding the trend and not competing for to anyone since what they offer is just a minimal betting feature which is not for competition. They are just bringing betting feature to all their existing customers but I doubt they can recruit new bettors just to bet in their betting function.
Lots of sportsbook offers much better feature than them
