Tesla Inc. (TSLA) CEO Elon Musk says he has already cast his ballot in Texas, and he would like you to know about it. In a post on X on Friday, Musk wrote, "I voted early today in Texas!!"

But the vote was only part of the message. In a follow-up post, Musk, who also runs Space Exploration Technologies Corp. (SPCX), laid out what he called his "biggest concern": a Democratic "clean sweep" of the presidency, House and Senate in 2028.

What worries him, he explained, is a chain reaction. First, statehood for Washington, D.C. and Puerto Rico, which would add Senate seats. Then open borders and legalization for everyone living in America illegally. Then, potentially, an expanded Supreme Court. Stack those together, and Musk says you get something much bigger than a bad election cycle.

"This would result in America becoming a permanent one-party state and the end of democracy in any meaningful sense of the word," he said.

His prescription is simple, at least as a message: keep at least 51 Republican Senate seats in 2029. Musk told voters to prioritize electing Republican senators above all other considerations, arguing that other issues matter less than preventing the scenario he described.

Immigration Warnings And A Very Large Checkbook

This is not a new theme for Musk. In December 2025, he warned that "importing voters" could create a single-party supermajority, pointing to Minnesota, California and New York. He argued that U.S. leaders are using immigration to build a left-leaning voter base dependent on government benefits, citing Rep. Ilhan Omar and Minnesota's Somali community. "We stand on the precipice of disaster, an end to America," he wrote at the time.

He has also been putting money behind the message. Musk reportedly planned to spend over $360 million backing Republican candidates in the midterms and donated $158 million to the Senate Leadership Fund, the main super political action committee (PAC) backing the party's candidates. That includes a group supporting Texas Attorney General Ken Paxton's Senate bid against Democrat James Talarico. Sen. Bernie Sanders (I-Vt.) has criticized Musk, accusing him of seeking to keep Republicans in power to increase his wealth. According to a New York Times report, Musk has contributed more than $276 million to Republican groups and his super PAC since early July.

And Musk has made clear he is willing to fight back. Following reports that Democrats could investigate him if they regain control of Congress, he vowed to target those he believes are orchestrating criticism against him. "Live by the sword, die by the sword," he warned, adding that he would pursue those "pulling the strings" rather than just their public-facing critics.

So yes, it is an election post. It is also a reminder that the richest person in the room tends to treat politics like a portfolio: concentrated positions, loud conviction, and no hedging.
