The White House is trying to stop "Prediction markets" where users can bet on everything from gas prices to the color of President Donald Trump's tie, but critics call them the "Wild West" of insider trading. The Commodity Futures Trading Commission has filed a lawsuit against Connecticut and two other states, arguing that prediction markets are not subject to state gaming laws and therefore therefore not legally regulated. The case is headed back to a lower court, but Connecticut Attorney General William Tong believes he will win the case. Sen. Richard Blumenthal, who is sponsoring legislation allowing states like Connecticut to regulate prediction markets, has accused the White House of exploiting insider trading and underage gambling.
