This market is closed now and was by a very inactive user, but I was jealous of its creativity and am copying it.

For the purposes of this market:

a Democratic Supreme Court Majority refers to when a majority of the Justices on the Court are appointed by US Presidents belonging to the Democratic Party.

For the definition of AGI, I refer to the terms defined in this Metaculus question.

I will be betting in this market. I don't foresee any plausible ambiguities in this question, but in the event of any ambiguities I consent to turning over the resolution of this market to trustworthy-ish users.
