Billionaire X owner Elon Musk has become one of former president Donald Trump’s most important financial backers, and certainly his most vocal in Silicon Valley, since endorsing him in July.

For the final month of the US presidential campaign, Musk has been pulling out all the stops, going “all in” on getting Trump back into the Oval Office, both online and IRL. He’s appeared at rallies; hosted town halls; poured well over $100 million into his own pro-Trump political action committee (PAC); started a (possibly illegal) giveaway of $1 million a day to voters in swing states; and used his social media platform and over 200 million followers to bolster pro-Trump messaging and conspiracy theories that could undermine faith in the election.

We’ve created a timeline to show Musk’s last month leading up to the election, with a particular focus on when he’s acting as a campaign surrogate, discussing how he might slot into a future administration, or putting money behind the campaign itself.
