Party nomination bets

[Wilder2016]

For the Republicans, I guess there's a chance of a convention coup, so it's prudent for books to wait a month to pay out.

The democratic nomination is over, but I'm still hearing from some places that they won't pay out until the convention. What are other people with these bets hearing?

Have bets on these across many different sites. None have paid, nor should they until the conventions.
