South Korean chip giant SK Hynix has raised a record-breaking $26.5bn ahead of its Wall Street debut amid soaring demand for semiconductors used in AI. SK Hynix said on Friday that it had sold 177.9 million American depositary shares (ADS) at $149 each ahead of its listing on the New York-based Nasdaq stock exchange. SK Hynix's 177.9 million ADSs are equivalent to 18 million ordinary shares. SK Hynix's initial public offering (IPO) marks the largest-ever listing by a foreign company in the US, surpassing Chinese e-commerce giant Alibaba's $25bn debut in 2014. The listing also ranks as the second-largest globally, after SpaceX's record-breaking $85.7bn Nasdaq listing in June.

Elon Musk becomes world's first trillionaire as SpaceX soars in stock market debut Elon Musk on Friday became the world's first trillionaire after shares in his SpaceX rocket company soared during the biggest-ever stock market debut. The Tesla and SpaceX founder comfortably cemented his status as the world's richest man, with his total net worth standing at $1.11tn (£828bn) according to the Bloomberg rich list. It came as the rocket, telecommunications and artificial intelligence (AI) company listed on the Nasdaq stock exchange with a value of $2.2tn. The company said its shares would be offered at $135 each, but trading opened at $150 and briefly reached $176.50 in a show of investor enthusiasm for potential business related to space and companies associated with Musk. SpaceX shares closed on Friday at about $161.

Elon Musk's SpaceX valued at nearly $1.8tn ahead of record share sale SpaceX has raised $75bn (£56bn) from financial firms ahead of it becoming a publicly traded company on Friday, in what is expected to be the highest-value stock listing in history. In a filing with the US Securities and Exchange Commission, the space exploration and artificial intelligence (AI) company said it had sold $75bn in shares priced at $135 each. The share price matches the estimate SpaceX gave last week, leaving the firm's expected initial stock market value to be nearly $1.8tn. At that value, chief executive Elon Musk - already the richest man in the world - is set to become the world's first trillionaire. Once shares start trading, their value could rise or fall depending on how many shares are made available for sale, and how strong the demand is for those shares.

Taiwan's economy is booming thanks to AI. For Li, an engineer at Taiwanese computer giant ASUS, the AI boom sweeping Taiwan has made it an exciting time to work in tech. Taiwan is a semiconductor powerhouse, producing about 90 percent of the most advanced chips used to power leading AI models such as ChatGPT and Claude. Still, Li worries that the spoils of Taiwan's AI windfall are not being shared equally. "Most industries unrelated to tech don't seem to be feeling the benefits, so it doesn't feel evenly distributed at the moment," Li said, explaining that many of his former classmates working outside of tech do not appear to be doing as well.

Elon Musk's SpaceX has revealed its plans to go public in the US, allowing people to trade shares in the firm on the stock market. SpaceX makes rockets, offers a satellite internet service called Starlink, and also owns Musk's controversial artificial intelligence (AI) firm xAI. The initial public offering (IPO) on the US stock market is set to be the largest in Wall Street history and could start next month under the ticker symbol SPCX. Because of the shares he will own in SpaceX, the IPO could make billionaire Musk, who is already the world's richest person, a trillionaire. SpaceX values itself at $1.25tn, and Musk's majority ownership of the company means his share could be worth more than $600bn.

'We could hit a wall': why trillions of dollars of risk is no guarantee of AI reward Progress of artificial general intelligence could stall, which may lead to a financial crash, says Yoshua Bengio, one of the'godfathers' of modern AI Will the race to artificial general intelligence (AGI) lead us to a land of financial plenty - or will it end in a 2008-style bust? Trillions of dollars rest on the answer. The figures are staggering: an estimated $2.9tn (£2.2tn) being spent on datacentres, the central nervous systems of AI tools; the more than $4tn stock market capitalisation of Nvidia, the company that makes the chips powering cutting-edge AI systems; and the $100m signing-on bonuses offered by Mark Zuckerberg's Meta to top engineers at OpenAI, the company behind ChatGPT. These sky-high numbers are all propped up by investors who expect a return on their trillions.

Stock markets had a stellar run in 2025. From North America to Europe and Asia, markets racked up some of the biggest gains in years. The globally-focused MSCI ACWI Ex-US index had its strongest performance since 2009, when the global financial crisis was in full swing. The index, which tracks non-US stocks in more than 40 markets, was on Wednesday on track to finish 2025 up about 30 percent, compared with the nearly 18 percent return of the benchmark S&P 500. The bullish streak marks a break from the decade-plus trend of US stocks dominating global indexes.
