If smart money can get rich in prediction markets, why aren't they? 

*leaderboard ranks by total profit rather than % so its possible non-whales have higher ROI

Shouldn’t an accurate prediction market have razor thin margins?

Not unless there is smart money in the market. Based on the leaderboard, the whales are not the smart money. They're providing most of the liquidity though, which suggests the markets aren't accurate.

Why do you assume they are not smart money? Genuinely curious and interested in prediction markets.

Don’t really care which of the candidates who only differ in optics will win but interested in this new sensemaking capabilities.

There are a lot of them who are betting millions per month but have negative ROI. That doesn't necessarily mean the ones with positive ROI are just getting lucky, but as I understand it the smartest money should be people with rare insider info that is likely only useful in a single market.
