Elon Musk was the world’s first trillionaire for 12 days

Elon Musk, the world’s richest man, briefly held onto the title of being the world’s first and only trillionaire before his net worth was deflated back down to a more modest nine-figure amount. On June 12, the day Space X began trading on the Nasdaq, Musk became the first person ever to have a $1 trillion net worth. But by June 24, his fortune had flattened down to $957 billion, according to Bloomberg’s Billionaires Index.During that period, the Space X and Tesla CEO was worth—depending on who was counting, using what measures, and what time during the day—somewhere between $1.32 trillion and $1.45 trillion at the top. Forbes also downgraded Musk’s status, but gave him a few extra million than Bloomberg did: $962 billion, after removing $116 billion of restricted Tesla stock from its math. The two trackers still agree on the durable fact: he is still, by a wide margin, the richest person on the planet. (Larry Page trails far behind as the world’s second richest person, with a net worth hovering around $300 billion). The round-trip excursion into trillionaire status was sponsored by SpaceX. The company priced its IPO at $135 a share and on June 12, raised a record $85.7 billion at a valuation near $1.77 trillion. Retail buyers chasing Musk’s dream of data centers in space and an eventual Mars settlement pushed the stock to about $225 on June 16, briefly valuing the company close to $2 trillion. However, by Tuesday’s close, it sat near $156, roughly 30% off the peak, and slipped further Wednesday, briefly dipping below the first-day pop price of $150.Musk’s stake, about 40% of the company, still accounts for the bulk of his fortune; Bloomberg pegs it around $744 billion, or about four-fifths of everything he owns. Scholars have raised concerns about the highly-concentrated nature of the SpaceX governance structure, in that shareholders have unusually little amount of control over the company’s future. The MSCI rated SpaceX a CCC, its worst rating
