With rivals racing to market to raise ‘eye-popping sums’, the spotlight is now on the AI sector’s one-time ‘poster child’

A year is a long time in AI. Just 12 months ago, Sam Altman was predicting his company OpenAI would build a super intelligence and fundamentally remake society. Now the boss of the ChatGPT developer is walking back those ideas after failing to make money from ads and erotic chatbots.

Meanwhile, rivals are storming ahead with plans to expand and go public on the stock market, in what is widely expected to be a season of record-setting initial public offerings (IPOs).

South Korea’s Kospi stock market has hit record highs thanks to AI, but experts urge caution over boom-bust cycles and a heavy reliance on two chipmakers

South Korea has leapfrogged India to become the world’s sixth largest share market, leaving equity markets in the UK, Germany and France trailing in its dust. But despite the runaway success, some are raising concerns that the Kospi index is too dependent on two freshly minted trillion-dollar chipmaking companies.

Chip company SK Hynix last week claimed a seat in Asia’s trillion-dollar company club, alongside South Korean compatriot Samsung Electronics and Taiwan’s TSMC. Explosive demand for chips used in AI has propelled the trio past the valuation threshold.

• Anthropic confidentially files for initial public offering on US stock market

In a landmark moment, gold has overtaken US government bonds as the world’s top reserve asset, according to calculations from the European Central Bank.

The ECB says that gold made up 27% of total official foreign reserves at the end of 2025, ahead of US Treasuries (22% of reserves) and the euro (15%).

Forces of fragmentation are becoming more pronounced. Geopolitical tensions continue to drive strong central bank demand for gold.

In nominal terms, the gold price surged by around 60% and 30% in 2025 and 2024 respectively, which mechanically increases the share of gold in total official foreign reserves.

Correcting for such valuation effects by using the gold price at the end of 2023, the share of the euro (16%) remains at par with the share of gold (16%), while the share of US Treasuries continues to be markedly higher (26%).
