The payment to a Green Bay man, which Musk announced Wednesday night on his social media platform X, is similar to a lottery that Musk's political action committee ran last year in Wisconsin and other battleground states before the presidential election in November.

The upcoming election on Tuesday, filling a seat held by a liberal justice who is retiring, will determine whether Wisconsin's highest court will remain under 4-3 liberal control or flip to a conservative majority. The race has become a proxy battle over the nation's politics, with Trump and Musk getting behind Brad Schimel, the Republican-backed candidate in the officially nonpartisan contest.
