It seems to be a "low stakes" academic prediction market project by a New Zealand university but seemingly it is regulated under CFTC rules.
And also seems very expensive (10% of winnings , 5% charge on cash withdrawals and non US get a 40USD wire charge), albeit on
very low maximum stakes.
The odds around some of the 2020 elections vs. special events seem a little out of whack:
Will Trump be President at end of 2019. "No" trades for 36cents
Who will win 2020 Presidential election. "Trump" trades for 31cents.
