ELON MUSK MAY have finally reached the end of his rope with President Donald Trump—and vice versa. While the world’s richest man wars with the US president on X, Republican strategists and insiders in Trumpworld tell WIRED that Musk’s broader future in Republican politics is on shaky ground.

Over the past few days on X, Musk has posted increasingly personal criticisms at Trump and the Republican budget reconciliation package known as the Big Beautiful Bill. This came to a head on Thursday, when Trump addressed the relationship during a press conference with German chancellor Friedrich Merz.

Musk poured hundreds of millions of dollars into Trump’s reelection bid, and their close relationship has been promoted by the pair countless times.
