Elon Musk was worth almost $200 billion at the beginning of 2024, the year he went all in on aligning himself with Donald Trump’s re-election bid. Since then, Musk has briefly become the world’s first trillionaire – and the biggest known political donor in the United States.

Musk’s ballooning wealth over the last two years– a gain of around $700 billion– has coincided with a political transformation, from previously a Democratic funder to one of the GOP’s most enthusiastic and generous backers. Now his future is increasingly intertwined with those new alliances– from federal contracts with the Trump administration to defenses against Democrat-led congressional investigations.

Musk is on track to be the election’s single biggest known political donor with almost half a billion dollars in spending ahead of the midterms, according to MS NOW’s tally of top individual donors at the federal level since 2010 based on campaign disclosures to the Federal Election Commission. He beat his own record this year after he contributed some $290 million to help Trump and Republicans win in 2024.

While there is not a clear direct link between Musk’s campaign contributions and the rapid growth in his fortune, his businesses’ contracts with the federal government have expanded over the past two years.

This cycle, Musk is pumping tons of cash into political organizations backing Republican candidates. So far he’s given at least $446 million in political donations to his own super PAC, America PAC, and other political groups and campaigns, according to FEC disclosures.

His single biggest fiscal priority this cycle so far has been the competitive Texas Senate contest between GOP Texas Attorney General Ken Paxton and Democratic state Rep. James Talarico. Musk has poured well over $200 million into the race through various super PACs supporting Paxton.

He’s been a prolific commenter on X, the social media platform he owns, attacking Democrats and warning that he will retaliate if lawmakers investigate him after the midterms. “Those who pick fights with me should understand that I will find out who is really pulling the strings and come for them, not just their puppets,” Musk wrote on X. “Live by the sword, die by the sword.”

His enormous spending has itself become a central focus for Talarico and his supporters. “This Senate seat doesn’t belong to Elon Musk. This Senate seat belongs to you. It belongs to the people of Texas,” Talarico said at a rally on Tuesday. “We have an affordability crisis because we have a corruption crisis.”It’s an about face for Musk, who just last year indicated he’d rein in his vast political spending. “I think I’ve done enough,” he said in May 2025 after a fierce public blowback to his role in the early months of Trump’s second term.

Since that period, which marked the end of his official role in policymaking, public opinion about Musk has failed to improve. The majority of Americans, 65%, say they dislike Musk, according to YouGov’s popularity tracker, as of early October.

The tech mogul is nearly a trillionaire. He officially crossed the trillionaire threshold earlier this year, but that valuation is tied to regular fluctuations in the stock market. His net worth was estimated to be nearly $920 billion, as of Thursday, according to data compiled by Forbes. The Bloomberg Billionaire Index, meanwhile, put his wealth at $913 billion.

The figure largely reflects his company stakes, including in his aerospace venture SpaceX and automaker Tesla, which both trade publicly. Both businesses have received billions of dollars in federal funds over the last two decades. Neither company responded to a request for comment on Thursday.

Musk’s super PAC did not immediately offer a comment for this story and MS NOW was unable to reach Musk directly by email. By December 2024, Musk’s net worth doubled in the wake of Trump’s election victory and his forthcoming return to office for a second term.

Musk, who was the world’s richest billionaire at the end of that year, was frequently seen spending time with Trump’s inner circle during the transition period, including at Trump’s Mar-A-Lago golf club and traveling on his private plane. Between 2024 and 2026, SpaceX’s valuation rose sharply as a result of the expansion of Musk’s AI business, known as SpaceXSI, along with the growth of his satellite internet-company, Starlink.

Some of his key firms are closely linked with the federal government, and a backlash among Democrats could weigh on parts of his empire in the long run. Under Trump, federal agencies have signed multiple contracts for use of Musk’s artificial-intelligence software, Grok, including the Pentagon and the General Services Administration. An online chatbot recently launched by the White House to disseminate federal information also utilizes Grok, along with Google’s AI software. Musk recently changed the name of his artificial intelligence business from xAI to SpaceXSI following Trump’s rebranding of AI as “super intelligence.”Earlier this month, he told a user on X– the social-media platform he owns– that he would reflect Trump’s preferred moniker in the company’s name. If the House comes under Democratic control, as polls suggest, Musk is likely to face investigations into his business dealings and his four-month stint in the Trump administration. After financially backing Trump’s presidential campaign, Musk was appointed to serve as a senior advisor and a co-leader of the government’s cost-cutting initiative, which he labeled the Department of Government Efficiency. DOGE made a series of controversial moves including the reduction of more than 300,000 federal workers, shuttering agencies created by Congress and suddenly slashing funding to aid programs that fed poor people around the world. Democratic lawmakers serving on the House Judiciary Committee accused the administration of targeting staff and leadership at agencies that have pursued investigations into Musk’s businesses, pointing to personnel firings including inspector generals, according to a Feb. 2025 fact sheet. The White House said Musk did not play a direct role in firing decisions and Musk dismissed conflict of interest concerns. Musk’s powerful role drew scrutiny given his numerous contracts with government entities. Trump notably attributed his departure in May 2025 to his criticism of a Republican-passed tax and spending bill that ended electrical-vehicle tax credits for Americans last year earlier than expected. Musk denied that the EV-credits attributed to his decision to leave Washington. He instead cited the statutory requirements for special government employees. The president threatened to review Musk’s federal contracts amid their falling out, causing Musk’s personal wealth to nosedive by $34 billion that day, according to the Bloomberg Billionaire Index, the second-largest loss in the tracker’s history.

The two men made amends sometime in late 2025. Musk made a sharp political shift in 2024 after previously supporting mostly Democrats, who he referred to as “the kindness party” which notably largely supported the electric-vehicle boom that Musk championed. Prior to 2024, he donated modestly to Democratic candidates, but at a much smaller scale than his million-dollar donations to Republican groups in recent years.
