RIP Polymarket, Long Live Polymarket

Polymarket got fined $1.4 million by the Commodity Futures Trading Commission and was ordered to cease noncompliant trading in the US.

Polymarket is probably the biggest prediction market currently available. US law considers unlicensed prediction markets to be somewhere between illegal gambling and illegal futures trading, ie definitely illegal. Polymarket and a few peers had survived anyway, through the “crypto is the Wild West and nobody has time to deal with all the illegal things happening there” exemption. Apparently they found time.

The rumor on the prediction market grapevine (which I absolutely cannot substantiate; please don’t sue me for libel) is that this might have something to do with competing prediction market Kalshi. Kalshi spent two years and probably a lot of money getting the CFTC to agree they were legal, and has a former CFTC Commissioner as a Director. Their legal status forces them to do an annoying and expensive regulatory dance all the time; illegal prediction markets were able to move more nimbly, provide better user experience, and eat their lunch. This was a big problem for them - but they’d just finished making lots of friends in the agency that decides which illegal things to crack down on, so, as Tyler Cowen likes to say, “solve for the equilibrium”.
