A Bloomberg-run daily ranking that tracks and estimates the net worth of the world's wealthiest individuals.
The 30% stake that made Sky Xu a $23bn founder is worth about $8bn at the listing price, and the roughly $73bn of company value that went missing says more about where Hong Kong's marginal IPO buyer went than about clothes.

SpaceX shares fell 3.5% to under $162 after a report that the company plans to raise $40 billion to buy Nvidia chips, Fortune reported. Fortune links the selling to debt worries in one hedged sentence, so the terms of the raise, which have not been reported, will decide whether investors are pricing leverage or dilution.
Reality
The $12.93 billion price works out to roughly $4,300 per model and $862,000 per integrating enterprise. The asset those numbers describe is the default place teams go for weights they could copy anywhere.

Nvidia director Mark Stevens led third-quarter insider sellers with $946.6 million of stock, ahead of Arista's Jayshree Ullal and Jeff Bezos. The three sellers' sales came to about 0.6% of their combined $302 billion fortune, so on the evidence they look more like diversification than a judgement on AI prices.

TaxWatch found David Reuben, said to have quit the UK over a possible wealth tax, has been tax resident in Monaco since at least 2014. Aggregate figures still show wealth leaving, so budget planning should rest on those numbers and on filed records.
Reality
Billionaires worth about $160 billion have left Britain or cut their ties in two years, by Bloomberg's count, more than those still in its index hold. The figure is net worth, not cash sent abroad, so the tax effect it can show is on who lives where and when they left.

Property magnate David Reuben has moved to Monaco about 18 months after the UK put long-term residents' global assets under its 40% inheritance tax. In California, where Prop 40's residency date has passed, opponents of the 5% levy are outspending supporters almost six to one.

UK billionaires worth $160bn, over half the country's billionaire wealth, have left or loosened ties since 2024, a Bloomberg index analysis finds. The figure counts net worth, so what Britain loses in tax receipts and investment still has to be estimated leaver by leaver.
Reality
David Reuben, worth nearly £28bn with his brother Simon, has left the UK for Monaco. By one count, billionaires worth £121bn have left or loosened UK ties since 2024, though for UK firms the open question is whether their capital follows them.

Elon Musk's net worth passed $1 trillion again on Monday, Forbes estimated, after SpaceX shares rose nearly 8% to $171.09. Swings of tens of billions a session now show up in a quoted price, and so far the reporting measures them only through his own wealth.

About 100 tech billionaires added a record $845bn in the first nine months of 2026, according to the Bloomberg Billionaires Index. The gains sit in a few US fortunes tied to AI share prices, so they describe this year's stock market better than next year's AI spending.

The Bridgewater founder said in a video for the World Economic Forum that over-investment in world-changing technology creates debt and then a bubble and then a bust. Fortune puts the dotcom version at a 77% Nasdaq fall.

Oracle disclosed the plan on the 11th and said on the 12th that Ellison had terminated it. Priced off the $341.39 close the same account reports for the 10th, the 50 million shares come to $17.1 billion.

Fortune puts Sky Xu's holding at about $8bn at the listing price, which divided by his 30% stake backs into a company worth roughly $26.7bn, some $73bn under the mark private investors accepted in 2022. Whether that gap is flows or freight decides who should buy it.

The Canadian parts maker's stock has outrun the TSX this year and its chair's fortune has more than doubled, because most of what Linamar sells was never tariffed in the first place.

California's billionaire tax faces a nine-figure defense built as ballot engineering: two counter-measures that only have to outpoll Prop 40, not beat it head-on.
