World's 500 Richest See Record $366 Billion Wealth Surge Driven by Tech

SpaceX’s market valuation was reported at about $2.5 trillion by the end of Monday’s trading session, with its valuation continuing to rise in Tuesday pre-market—up an additional 10% after the debut.
While Elon Musk led the Bloomberg rankings, the article also listed the next richest figures: Google co-founders Larry Page ($314 billion) and Sergey Brin ($292 billion), Amazon founder Jeff Bezos ($267 billion), and Oracle co-founder Larry Ellison ($247 billion).
The threshold for entering the Bloomberg Billionaires Index’s top 500 was reported as the last group holding around $7.9 billion each—described as the highest-ever entry level for inclusion.
Bloomberg Digital’s Joe Weisenthal reported the combined single-day gain at $366 billion (vs. $336 billion in other accounts) and said that “heightened retail interest” could make the SpaceX IPO attract strong participation from individual investors.
Another report said Musk briefly became the first person to surpass a $1 trillion net worth during SpaceX’s early trading, and claimed SpaceX shares climbed to around $163 after the market debut.
The world's 500 richest people added a record $336 billion to their combined wealth in a single trading day on June 15, according to Bloomberg Billionaires Index. That breaks the previous one-day record of $304 billion set just two months earlier. Their total net worth now stands at roughly $13.3 trillion.
Elon Musk drove nearly half the gain alone, adding $164.8 billion in one day — more than Warren Buffett's entire lifetime fortune of $148 billion, The Economic Times reported. The surge came as SpaceX shares soared nearly 20% after the company's Nasdaq debut and as global markets rallied on news of a U.S.-Iran deal to reopen the Strait of Hormuz.
SpaceX debuted on the Nasdaq under the ticker SPCX on June 12, priced at $135 per share and raising $75 billion. Shares closed the first day at $160.95, according to Forbes. By Monday June 15, shares had surged another 20% to close at $192.46, pushing SpaceX's market value to roughly $2.5 trillion.
That rally briefly made Musk the first person in history to surpass a $1 trillion personal net worth, with his fortune reaching $1.32 trillion, World Socialist Web Site reported. By Tuesday pre-market, SpaceX shares climbed an additional 10.4% to $212.50. Bloomberg Digital's Joe Weisenthal revised the single-day wealth gain upward to $366 billion, citing "heightened retail interest" from individual investors flooding into the stock.
On June 14, a tentative U.S.-Iran digital agreement was reported, aimed at reopening the Strait of Hormuz to commercial shipping. President Trump declared the route "totally safe," according to MEAWW News. The deal involves automated maritime tracking and a temporary halt on cyber-attacks against shipping infrastructure.
The news acted as a relief valve for global markets. Major stock indexes pushed near highs on June 15. The shipping industry remained cautious, however, with representatives calling conditions "very risky" despite the agreement, MEAWW News noted.
Retail investors bought more SpaceX stock since its IPO than all other stocks combined during the same period, according to Morning Brew. Supporters argue the $2.5 trillion valuation is fair for a company that controls global satellite internet through Starlink, dominates the rocket launch market, and now operates leading AI tools after merging with xAI in February 2026.
Skeptics are far less convinced. Swissquote Bank senior analyst Ipek Ozkardeskaya said bluntly, "This valuation makes absolutely no sense today. People are buying SpaceX in the expectation that others will buy too... that's speculation," according to News.Az. SpaceX posted revenue of $18.7 billion in 2025 — a tiny fraction of its $2.5 trillion market cap. Joe Saluzzi of Themis Trading compared the stock to a "meme stock" driven by leveraged ETFs and short-term capital, South China Morning Post reported.
The top 50 billionaires in the index now hold $6.5 trillion combined. The remaining 450 people in the index hold $6.8 trillion — only slightly more, according to TradingView. The minimum net worth needed just to enter the top 500 hit $7.9 billion, the highest entry threshold ever recorded, Anadolu Agency reported.
The other top billionaires on the Bloomberg index include Google co-founders Larry Page at $314 billion and Sergey Brin at $292 billion, Amazon's Jeff Bezos at $267 billion, and Oracle's Larry Ellison at $247 billion, The Economic Times reported. Musk's gain in just six days totaled $624 billion — a pace that works out to roughly $1.2 million per second, according to World Socialist Web Site. Lawmakers are now debating "Trillionaire Taxes" and antitrust actions targeting Musk's growing multi-industry empire, Bloomberg noted.
