Elon Musk is putting his money where his X is.

The billionaire entrepreneur has committed $45 million per month to Republican get-out-the-vote and early-voting efforts, according to a report Monday in the Wall Street Journal.

Citing “people familiar with the matter,” the newspaper reported that Mr. Musk’s money will go through a new super political-action committee called America PAC.

The group was formed in June and, according to the Journal, focuses “on registering voters and persuading constituents to vote early and request mail-in ballots in swing states.”

The super PAC’s other backers, the Journal reported, include Joe Lonsdale, the cofounder of Palantir Technologies; the Winklevoss twins, capital and cryptocurrency investors; and Joe Craft, chief executive of coal producer Alliance Resource Partners.
