AI boom adds more than half a trillion dollars to wealth of US tech barons in 2025
A stock market boom in artificial intelligence companies has added more than half a trillion dollars to the wealth of America’s tech barons in the past year, data shows,The top 10 US founders and bosses of some of the world’s largest technology companies saw their finances swell to nearly $2,5tn, up from $1,9tn, in the year to Christmas Eve, according to figures from Bloomberg,Elon Musk, already the world’s richest man, has again proved to be one of biggest winners as the AI gold-rush has pushed US stock markets to record highs.
Musk’s net worth increased by nearly 50% year-on-year to $645bn.The tycoon, whose business interests include xAI, an artificial intelligence company, became the first person to have a net-worth of more than $500bn in October this year.He could become the world’s first trillionaire if he hits targets set by Tesla, the electric car company he runs.Musk sits ahead of Google co-founder Larry Page and Amazon founder Jeff Bezos in the overall rankings of the world’s wealthiest billionaires.Page is estimated to be worth $270bn, and Bezos $255bn.
The growing concentration of wealth among an ultra elite has fuelled debate about how best to rebalance economies, with some calling for more effective wealth taxes,The chief executive of the chipmaker Nvidia, Jensen Huang, was also one of the biggest gainers,The value of his investments, equity and other assets rose $41,8bn, taking his personal fortune to $159bn,This puts him ninth in the overall Bloomberg Billionaire Index, and eighth among the top 10 US tech billionaires, according to a separate report from the Financial Times.
Huang sold nearly $1bn worth of shares this year, cashing in on Nvidia’s soaring stock price.Its relatively advanced computer chips are a critical component in building the more powerful processing capability required by AI.It became the world’s first $5tn company in October, larger than the economic output of some of the world’s biggest economies, such as Japan or India.The wealth of Page and Sergey Brin, the co-founders of Google, swelled by around $102bn and $92bn respectively, as investors bet on the company’s AI progress, including its own in-house efforts to build new chips, known as a Tensor Processing Unit.Such has been the surge in AI investments in recent years that the Bank of England has warned of a “sudden correction” in global markets if investor confidence proves misplaced.
“On a number of measures, equity market valuations appear stretched, particularly for technology companies focused on artificial intelligence,” top policymakers at the central bank said in October.This means that stock markets are “particularly exposed should expectations around the impact of AI become less optimistic”, they said.While technology is the dominant industry among gainers in the billionaire rankings, there are other familiar names, too.Bernard Arnault, the French chair of the LVMH luxury goods company, which makes the likes of Louis Vuitton bags and Dom Perignon champagne, saw his wealth rise by $28.5bn over the past year.
The 76-year-old controls around half of LVMH and analysts have turned more positive on the stock in recent months, with strong spending by wealthy North American consumers,The Spaniard Amancio Ortega, who holds 59% of Inditex, the parent company of the high street clothing retailer Zara, and seven other brands, was among the biggest gainers, adding $34,3bn to his fortune, which sits at $136bn,This was boosted by a record dividend of €3,1bn from the retail group.

Elon Musk warns of impact of record silver prices before China limits exports
A surge in the price of silver to record highs this month has prompted a warning from Elon Musk that manufacturers could suffer the consequences.Silver has risen sharply during December, part of a precious metals rally that also pushed gold and platinum to record levels on Boxing Day.Analysts have attributed the jump in prices to expectations of US interest rate cuts by the Federal Reserve in 2026, leading to increased demand for hard assets that protect against inflation and currency debasement.New restrictions on silver exports from China, which begin on 1 January, have created supply fears while geopolitical worries have lifted demand for safe-haven assets.Silver hit $79 (£58) an ounce for the first time last Friday, a new peak, up from $56 at the start of December, and just $29 an ounce at the start of 2025
AI is coming for young people’s office jobs. That’s good news for the construction industry | Gene Marks
While standing on the sideline watching a high school soccer game, my friend, who owned a small and successful construction company, complained that his son – a senior – was starting at a respected local university that fall, which would cost roughly $200,000 over the next four years.“I could take the same money and set him up in a contracting business,” he said. “It would be a much better investment.”That was in 2010. The kid did go to that college and graduated four years later with a degree in history
Nvidia insists it isn’t Enron, but its AI deals are testing investor faith
Nvidia is, in crucial ways, nothing like Enron – the Houston energy giant that imploded through multibillion-dollar accounting fraud in 2001. Nor is it similar to companies such as Lucent or Worldcom that folded during the dotcom bubble.But the fact that it needs to reiterate this to its investors is less than ideal.Now worth more than $4tn (£3tn), Nvidia makes the specialised technology that powers the world’s AI surge: silicon chips and software packages that train and host systems such as ChatGPT. Its products fill datacentres from Norway to New Jersey
From shrimp Jesus to erotic tractors: how viral AI slop took over the internet
Flood of unreality is an endpoint of algorithm-driven internet and product of an economy dependent on a few top tech firms In the algorithm-driven economy of 2025, one man’s shrimp Jesus is another man’s side hustle.AI slop – the low-quality, surreal content flooding social media platforms, designed to farm views – is a phenomenon, some would say the phenomenon of the 2024 and 2025 internet. Merriam-Webster’s word of the year this year is “slop”, referring exclusively to the internet variety.It came about shortly after the advent of popular large language models, such as ChatGPT and Dall-E, which democratised content creation and enabled vast swathes of internet denizens to create images and videos that resembled – to varying degrees – the creations of professionals.In 2024, it began to achieve peak cultural moments
MCG pitch is easy scapegoat but sloppy cricket is to blame for early Ashes finishes | Geoff Lemonff
You know that something has gone wrong when the man in charge of the cricket pitch is giving a post-match press conference. Australian pitches are celebrities in their own right, each with a distinct perceived personality. Perth – gasoline, bounce. Sydney – intrigue, spin. Adelaide – graft, a late finale
