Mark Cuban warns Elon Musk: Trump’s ‘loyalty is only to himself'

• Mark Cuban cautioned Tesla CEO Elon Musk against forming an alliance with Donald Trump, because, he said, the Republican presidential nominee may not ultimately repay his political debts.
• Cuban and Musk are on opposite sides of the 2024 presidential election, but each have their eyes on governmental regulatory roles.
• As Musk supports Trump, he has repeatedly raised his hand to lead a new "government efficiency commission" in the hypothetical Republican administration.
• Meanwhile, Cuban, an outspoken surrogate for Vice President Kamala Harris, has suggested he would be open to leading the SEC if she wins the White House.

Billionaire investor Mark Cuban cautioned Tesla CEO Elon Musk on Sunday against forming an alliance with former President Donald Trump, because, he said, the Republican presidential nominee may not ultimately repay his political debts.

"Elon, there will come a time when you need something from Donald Trump," Cuban wrote in an X post to his fellow billionaire. "You will think you will have earned the right to ask and receive. You have been a loyal, faithful soldier for him."

"At the point you need him the most," Cuban continued. "You will find out what so many before you have learned, his loyalty is only to himself.

Cuban's message came in response to an earlier X post from Musk in which the SpaceX CEO amplified a variety of conspiracy theories about Democrats encouraging immigration into battleground states as "a surefire way to win every election."

"If Trump is NOT elected, this will be the last election," Musk wrote.

Musk's endorsement of Trump is a stark reversal from 2022 when he would openly sling insults at the former president on social media.
