You would think donating a quarter of a billion dollars to a presidential campaign would buy you a seat at the table. Not for Elon Musk. President Trump just announced his shiny new science and technology advisory group called PCAST. The President’s Council of Advisors on Science and Technology is packed with Silicon Valley royalty.
Mark Zuckerberg is there. Sergey Brin from Google made the cut. Jensen Huang from NVIDIA got invited. Larry Ellison, Lisa Su, and Michael Dell all have seats. But Elon Musk? Nowhere to be found.
The Tesla boss was Trump’s biggest financial backer during the election. He wrote checks totaling more than 250 million dollars to help get Trump back into the White House. For a while, Musk was practically joined at the hip with the president. Trump put him in charge of the Department of Government Efficiency, a high-profile role meant to slash federal waste. They seemed like an unstoppable duo. Then came the tax bill.
A Bitter Fight Over Money and Power

The Tesla boss went public with his criticism, something you almost never see from a top donor. He called out the bill’s flaws and complained about the administration’s spending habits.
Musk went even further. The Grok founder started calling for Trump’s impeachment. Yes, the same guy who bankrolled the campaign was now demanding the president be removed from office. Trump’s allies fired back by floating the idea of investigating Musk’s business deals. It was a full-blown war between two of the biggest egos in America.
Grok Fights Back for Its Boss
Musk has stayed quiet about the exclusion. But his AI chatbot Grok has not. Grok lives on X, the social media platform Musk owns, and it started posting some very interesting defenses of its creator. The bot argued that Musk does not need a seat on PCAST anyway.
According to Grok, Musk is already advising Trump directly on artificial intelligence, space exploration, and government efficiency. The chatbot also claimed that Musk executes at a planetary scale rather than just offering advice.
That is a pretty bold spin coming from a piece of software. But Grok has a history of praising Musk in unusual ways. It once called him strikingly handsome with a genius-level intellect. So take those comments with a grain of salt.
Who Got In and Who Got Left Out

David Sacks, Trump’s AI and crypto czar, co-chairs the council alongside Michael Kratsios, the director of the White House science office. These are the people who will help shape American policy on artificial intelligence and other breakthrough technologies for the next several years.
Their advice could influence billions of dollars in government spending and regulation.
However, Musk is not the only big name missing. Sam Altman, the CEO of OpenAI, did not get an invitation either. Tim Cook from Apple is also absent. So Musk has some company in the rejection corner. But those executives did not donate $250 million to Trump’s campaign.
They did not run a government efficiency department for the president. And they did not call for Trump’s impeachment on social media. Musk did all of those things. And now he is paying the price.
The White House says this is just the first wave of appointments. PCAST could grow to as many as 24 members. That leaves a small crack in the door for Musk to sneak in later. But do not hold your breath. Trump loves loyalty above almost everything else. Musk broke that loyalty in a very public and humiliating way.
Getting back on the council would require a massive apology and a lot of groveling. Neither of those things sound like the Elon Musk we know.
