Market Inefficiency or Extreme Uncertainty?

[Hamzaal24]

The crypto exchange FTX offers the ability to gamble on the winner of the 2020 US presidential election.
The winning odds of all candidates adds up to only 0.973. That means the market values a 2.7% chance that no candidate from a major party wins the election.
The last person who was unaffiliated with a major party yet won the election was George Washington, in 1793.
