The facts
Forbes estimates Elon Musk's net worth at $1 trillion as of Monday morning, Oct. 5, 2026. That is $30.6 billion more than Friday, the last day the market was open. He is first in the world. Jeff Bezos is second, at $371.5 billion. The gap between them is larger than Bezos.
The Monday move was mostly SpaceX. Forbes said the stock was up more than 5 percent, to $167 a share, at 10:30 a.m. Eastern. Tesla was up more than 1 percent. Forbes tied the SpaceX pop to a Morgan Stanley note that called the shares undervalued, and to a Starship launch last week, which the magazine described as the rocket's first time reaching orbit. It also noted that on Sunday Musk suggested the company's AI arm, SpaceXAI, should be renamed SpaceXSI, because President Trump has said "artificial intelligence" ought to be called "super intelligence." That is a suggestion, not a completed rebrand.
Friday was the setup. Forbes had Musk at $979.7 billion at 2:15 p.m. that day, up $61 billion, or 6.64 percent, from Thursday. SpaceX was up more than 7 percent, at $158.84. Tesla was up about 5 percent, at $371.32, after the company reported 486,532 third-quarter deliveries, ahead of analysts, which gave the market hope Tesla might avoid a third straight year of falling deliveries. Bezos was at $370.7 billion on Friday. By Monday the No. 2 fortune had ticked up to $371.5 billion and still was not in the same sport.
This is the third time Forbes has had him over the line in 2026. He became the first person to hit a $1 trillion fortune on June 12, the day SpaceX started trading on the Nasdaq. The shares opened at $150. Forbes put the company's market value near $2 trillion that day and Musk's fortune at $1.1 trillion. It peaked at $1.45 trillion in the week after the listing. He then lost the title. Forbes said a 31 percent drop in SpaceX later in June did part of the damage. Separately, Forbes took $116 billion of restricted Tesla stock out of the estimate after Musk gave up $7.1 billion in shares to cover the exercise price on the options from his 2018 pay deal. An April agreement with Tesla had already fenced that block off.
He got the title back on June 29. SpaceX rose 7.6 percent and Tesla 8.6 percent that day, and Forbes added $62.3 billion, putting him over $1 trillion again. At that point Forbes was counting 4.8 billion SpaceX shares, another 350 million options with an $8.40 exercise price, and about 700 million Tesla shares he had disclosed. The return lasted until July 1.
The standing Forbes profile, updated in September, says he owns 38 percent of SpaceX including options, and nearly 11 percent of Tesla, not counting unvested stock from the 2018 award that could add about another 8 percent before taxes. SpaceX, started in 2002, bought xAI in February in a deal that valued the combination at $1.25 trillion. Twitter, which he bought in 2022, had already been folded into xAI. He also has the Boring Company and Neuralink. He is 55, lives in Austin, and has been the richest person in the world since May 2024. Forbes lists his philanthropy score at 1. In February he said less than 0.1 percent of the net worth was cash.
None of this is a paycheck. Forbes is marking a pile of stock to the last trade. The pile was under $1 trillion on Friday afternoon and over it on Monday morning. It has already made this trip twice.
Our take
He did not get paid a trillion dollars before lunch. A sell-side note, a rocket flight, and a 5 percent pop in a stock he already owns put a Forbes calculator back over a round number. Friday the same calculator said $979.7 billion. The difference is one good mood in the market. He has already watched that mood leave. June 12 he was the first trillionaire in history. The stock dropped and the title left. June 29 it came back for a holiday weekend. July 1 he was a billionaire again, which is a humiliating sentence only if you have never met an actual billionaire.
Bezos at $371.5 billion is the punchline people will miss. Second place is not close. Second place is a whole other fortune that still does not cover the air between them. Musk could lose more than Bezos owns and remain the richest man alive, which is what happened on the way down from $1.45 trillion, and he was still first.
The Sunday bit is the tell. The AI shop might get renamed SpaceXSI so the initials flatter a president who wants "super intelligence" as the brand name. The rocket company is worth whatever the last buyer paid. The rebrand is free. Forbes, which keeps the score, gives the philanthropy a 1. He said in February that less than a tenth of 1 percent of this pile is cash. Less than a tenth of 1 percent of the headline is cash. The rest is a quote.
Round three is not a coronation. It is a stock quote with a shorter memory than he has. He is a trillionaire until the next red day. He has already practiced.
