Elon Musk Is Positioning X Behind the New Trump Presidency

Since the election, Mr. Musk has used his social media company to talk up how bright the future will be under the president-elect.

Since Donald J. Trump won the presidential election, Elon Musk has gone all in on X to promote the incoming administration.

Mr. Musk, who owns X, posted on the platform about politics more than 400 times between Tuesday and Friday, celebrating Mr. Trump’s victory and talking about the causes that the president-elect should take up in office. Mr. Musk’s posts included a photo of himself and his son X Æ A-Xii Musk surrounded by Mr. Trump and his family at Mar-a-Lago, as well as another photo of himself with Mr. Trump that was captioned “Novus Ordo Seclorum,” a Latin phrase that appears on the dollar bill and means “a new order for the ages.”

Linda Yaccarino, X’s chief executive, also chimed in. In reply to a post this week about the platform’s role in driving political conversation, she wrote, “Reporting for duty.”

Their comments show how Mr. Musk is increasingly positioning X as the platform behind the new Trump presidency. Since the election was called on Wednesday, Mr. Musk has used X to talk up how bright the future will be under the president-elect. In addition, he has urged X’s users to replace the news media and report on Mr. Trump’s triumphant return to office, and has promoted the platform as a go-to destination for continuing conservative conversation.

That comes on top of how Mr. Musk has used X as a battering ram for months to support Mr. Trump’s campaign. Mr. Musk, who endorsed Mr. Trump in July, held a wide-ranging audio conversation with him on X in August. That same month, Mr. Trump started using his reinstated account on the platform regularly.

On Tuesday, Mr. Musk held an audio town hall on the site urging his more than 203 million followers to vote for Mr. Trump. The president-elect credited Mr. Musk on Wednesday for helping secure his win. “A star is born — Elon!” Mr. Trump said during his victory speech.
