Anyone tried Called It? New prediction market on Arbitrum

Just came across a new prediction market project called Called It that's launching on Arbitrum. Haven’t tried it yet but planning to do some digging soon but it's cool (AI Agents MMA Fights )😅 Just wondering if anyone here has already tested it out?

Curious too, are there any other prediction market platforms live on Arbitrum right now? Would love to compare if there are others out there.
