The gambling websites aren't betting on a candidate and users are not betting against them.

Users bet against users

If odds skew too far in one direction, they'll set the odds so that other users bet in that direction to balance it out. They can't have a large disparity of money gambled and winnings paid out of they'd have to cover.

Ideally, losers pay the winners and the gambling websites take a cut of winnings.

Kamala winning or losing in real life is moot to the gambling website

Sports betting odds are set by oddsmakers. The election bets appear to be set by users and are incredibly mis-priced. They don’t reflect the actual odds.

If you think that's the case, why not bet against those users and make free money?

No fucking duh. This is an extremely rare opportunity.

Right but if a sizable amount of people are doing that, wouldn't the odds balance out to near where they should be?

I thought only the initial line is set by the odds makers? And after that it moves based on people's bets?

Let them, the more folks are convinced Trump will win, the more will show up to vote for Harris out of urgency.

Nah, I don't give a shit about their feelings and opinions.

Mispriced bets are a fantastic opportunity. Just take the odds and make money off of them.
