A small group of seven companies, including Alphabet, Amazon, Apple, Meta Platforms, Microsoft, Nvidia and Tesla, have become so dominant that they alone contributed to more than half of the S&P 500’s

Global shares in $1 trillion rout after China's DeepSeek sends AI and tech stocks plunging - DeepSeek’s app is said to have cost olny $6 million to develop

By Sinéad Carew, Amanda Cooper and Ankur Banerjee LONDON/SINGAPORE (Reuters) - Investors made a quick exit from a host of technology stocks from Tokyo to New York on Monday as the emergence of a low-cost Chinese artificial intelligence model challenged the dominance of current AI leaders such as Nvidia .

SoftBank Group CEO Masayoshi Son is shifting his focus away from investments in China and toward the US, as seen with his involvement with President Donald Trump and the recently announced Stargate.

DeepSeek threatens to disrupt the AI sector in a similar fashion to the way Chinese companies have already upended industries such as EVs and mining.

In international markets, chipmaking and electrification companies saw pressure on the fears over the DeepSeek AI service. SoftBank -- the company that said it would fund up to $500 billion in AI infrastructure as well as the main shareholder of microchip designer ARM -- saw its stock dive 8%.

BANGKOK (AP) — World shares were mixed on Thursday after China rolled out more moves to try to boost its lagging stock markets by raising confidence that prices will rise. Germany's DAX gained 0.2% to 21,300 and the CAC 40 in Paris edged 0.1% higher to 7,847.38. Britain's FTSE 100 slipped less than 0.1% to 8,539.88.

SoftBank CEO Masayoshi Son's plan to invest billions in AI in the United States shows one way to handle the new Trump administration: go big and deal with the details later.

The partnership formed by Oracle, OpenAI and SoftBank is due to invest up to $500 billion. SoftBank's shares rose 3.7% on Thursday in Tokyo trading after jumping 11% the day before. Elsewhere in Asia, the S&P/ASX 200 in Australia fell 0.6% to 8,383.50, while the Kospi in Seoul lost 0.8% to 2,526.98.

Chinese startup DeepSeek has shaken the belief that only a few firms with huge budgets can compete in the artificial intelligence field — potentially challenging an investment case that rewarded the biggest players with rich valuations.

On the second day of his presidency on Tuesday, Donald Trump announced the Stargate Project, a $500 billion joint venture among OpenAI, Softbank, Oracle, and MGX, to build AI-focused data centres across the US.
