From rockets to brain implants, here's a look at Elon Musk's vast empire

NEW YORK (AP) — Elon Musk, the world's richest man and now first-ever trillionaire, controls a lot of different businesses.

Electric vehicles. Brain implants. Underground tunnels. A social media platform once called Twitter. And a rocket maker that blasted off its trading from Wall Street this week.

Over time, more and more of these ventures have found themselves under the same roof. Musk merged SpaceX — which went public on Friday — with his artificial intelligence company xAI just earlier this year. But he still holds the CEO role at several corporations today, in addition to other various executive titles or ownership stakes.

Here's a look at Musk's vast business empire.

Musk is CEO of SpaceX, which he founded in 2002. The company has grown far beyond rockets. It owns satellite communications service Starlink, a big source of cash for the company that generated $4.4 billion in operating income last year. SpaceX also houses social media platform X, formerly known as Twitter, which Musk bought for $44 billion in 2022 and parked it under xAI, the maker of the Grok chatbot.

Both xAI and X are money losers (the AI business lost $6.4 billion in operations last year). Nonetheless, SpaceX — which lost $2.6 billion overall from operations last year — was able to whip up enough market hype to debut with the biggest initial public offering in history on Friday, closing at just below $161 per share, or a total market value of $2.1 trillion.

Some think that price tag significantly overvalues the company. SpaceX has promised it will become a leader in AI and one day help make human life multiplanetary — with lofty, and at times sci-fi sounding, goals that range from putting data centers in space to colonizing Mars. But the bulk of that hinges on unproven technology and massive capital needs.

Musk is also CEO of Tesla, a role he has held at the electric car maker since 2008.

Tesla has struggled with rising competition in the EV space. Last year, the company lost its crown as the world’s largest EV maker to China’s BYD. Sales were also bruised during boycotts over Musk’s politics. Those numbers have since rebounded some, but Musk has repeatedly shrugged off troubles — emphasizing that Tesla’s future lies less in car sales than getting people to take rides in them as self-driving taxis.

Beyond the road, Tesla has been upping production of robots for homes and businesses. And it's also been in the solar energy business for about a decade with it purchase of SolarCity, which was founded by Musk and two of his cousins. Tesla went public in 2010, and went on to join the trillion dollar club on the S&P 500. Its market cap currently stands around $1.5 trillion.

Musk has also the CEO title at Neuralink, a brain-computer interface company he co-founded in 2016.

Neuralink is one of many groups working to connect the human nervous system to machines. It's launched clinical trials for people who have spinal cord injuries, ALS and other conditions. The company (and sometimes Musk himself ) has announced a handful of brain implants over recent years. In January, Neuralink said it had 21 trial participants worldwide.

Musk also founded The Boring Company, a decade-old tunnel digging and underground transportation business.

The Boring Company is behind projects like the “Vegas Loop” — a network of underground, Tesla-hailing tunnels that first opened around around the Las Vegas Convention Center in 2021. It's promised to deliver a network of high speed transit — with plans to also make tunnels in Dubai and Nashville. Still, pushback has piled up along the way. The company has been accused of breaking multiple safety and environmental requirements in Las Vegas, where its full route is still unfinished, and other criticism from some local officials in Nashville.

Musk made his initial fortune by creating two companies, Zip2 and PayPal ( once X.com ). Those then-startups were sold to new owners decades ago — but netted him about $200 million at sale, which Musk used to later start SpaceX and invest in Tesla.

WASHINGTON (AP) — One by one, the burly mixed martial arts fighters made their entrance past the solemn, hulking marble statue of America's 16th president and jogged down the steps of the Lincoln Memorial to roars from thousands of fans drawn to the unusual sporting weekend marking the nation's 250th anniversary and President Donald Trump's 80th birthday.

The news conference Friday night featured the fighters who are preparing to face off Sunday in the Octagon built outside the White House. But it was also a chance to see the UFC fans who have thronged to Washington and endured lightning, humidity and bugs for the spectacle.

Tracy Philbeck and his son Levi drove from Charlotte, North Carolina, with a group of friends to support their favorite fighter, American Justin Gaethje, in the upcoming lightweight title bout against Georgian Ilia Topuria.

"You will hear an eagle screaming when Justin Gaethje wins,” the elder Philbeck chuckled.

David Halstead journeyed from Albany, in Western Australia, to watch the sport he has loved for a decade. Halstead said Trump, who regularly attends the fights, “put UFC on the map."

The UFC has said it spent $60 million on this weekend's festivities, and Republican president has billed it as “the greatest show on earth.”

Not everyone agrees.

The Public Integrity Project described the event as a “private, commercial, corrupt use of our most sacred national monuments for private gain” in a lawsuit the watchdog group filed to try to stop it from happening on federal land. A federal judge ruled on Friday that the White House was allowed to go ahead.

Only about 1 in 10 U.S. adults consider themselves mixed martial arts fans, according to Ipsos Sports polling conducted in February and March. That polling suggests MMA fans skew male and nonwhite. They are more likely to identify as Republicans than Democrats.

“One misconception is that everyone who watches UFC is a Trump supporter, but that’s not the case," said Ricardo Rodriguez, 24, explaining he loves the physicality of the sport. “People also expect a knock out every time," he said.

Ellie Louizes, who practices Muay Thai, or Thai kickboxing, and jujitsu martial arts, drove from Daytona Beach, Florida, with her boyfriend, Jacob Purvis.

Female fans of MMA are the minority. But Louizes said she knows a lot of women who get into watching the sport through their male partners. She said “female fighters are often way more aggressive” than the men.

The fans at the Lincoln Memorial brushed off criticism about the bouts being held at the White House.

Holding fights at the “People's House,” Tracy Philbeck said, "goes back to the days of Teddy Roosevelt.”

Roosevelt regularly held sparring sessions at the White House, though they were not formal public prizefights. He was an enthusiastic amateur boxer who had boxed at Harvard and continued the sport throughout much of his life.

Boxing fans also make up a large part of the UFC's fan base.

At a UFC-sponsored community event this week at the District of Columbia's Midtown Youth Academy, the boxing gym's executive director was helping out with a visit from UFC fighter Randy Brown, who sparred with more than dozen local teenagers and preteens.

Gloria Lee said meeting the fighter was a big deal for kids at her gym. “It's just been a thrilling week, and I was about to fall out when he came in the door!” she said.

Asked about her personal UFC fandom, Lee said she had not watched it much. But by the end of Brown's visit, she got into the ring with the professional fighter and threw some slugs of her own.
