Elon Musk Gets a Crash Course in How Trumpworld Works

The world’s richest person, not known for his humility, is still learning the cutthroat courtier politics of Donald Trump’s inner circle — and his ultimate influence remains an open question.

For the first 53 years of his life, Elon Musk barely spent any time with Donald J. Trump. Then, beginning on the night of Nov. 5, he spent basically no time without him.

And so Mr. Musk, more than any other key player in the presidential transition, finds himself in a cram session to learn the courtier politics of Mr. Trump’s inner circle. For the world’s richest person — not known for his humility or patience — it is a social engineering challenge far trickier and less familiar than heavy manufacturing or rocket science.

Doubts abound as to whether he will graduate in 2028 with a four-year degree in Trumpism: It is now a parlor game in Washington and Silicon Valley to speculate just how long the Musk-Trump relationship will last. The answer, as discarded aides from Mr. Trump’s first term will tell you, may depend on Mr. Musk’s ability to placate the boss and keep a relatively low profile — but also to shiv a rival when the time comes.

In short, how to play the politics of Trumpworld.

Most of the people who now surround Mr. Trump in the transition are battle-tested aides from his past fights, or decades-long personal friends. Mr. Musk is neither. What he brings instead are his 200 million followers on X and the roughly $200 million he spent to help elect Mr. Trump. Both of those have greatly impressed the president-elect. Mr. Trump, gobsmacked by Mr. Musk’s willingness to lay off 80 percent of the staff at X, has said the tech billionaire will help lead a Department of Government Efficiency alongside Vivek Ramaswamy.

Over the last week, Mr. Musk has kept up his buddy routine with Mr. Trump, joining him at nearly every meeting at Mar-a-Lago as well as a U.F.C. fight. On Tuesday, he brought the president-elect to the Rio Grande Valley in Texas for a SpaceX launch.
