What you need to know

China's stock markets have lost roughly $2.4tn since May, The Guardian reports, citing Bloomberg, as the Shanghai STAR 50 tech index fell 40% from June. Weak consumer demand, thin AI-sector profits and widening US restrictions are weighing on Beijing's AI ambitions, with AI stocks now over 40% of China and Hong Kong market value per Goldman Sachs.

  • The Guardian, citing Bloomberg, reports about $2.4tn wiped from Chinese stocks since May.
  • The STAR 50 technology index has fallen 40% since June; other major indexes dropped about 20% over the same period.
  • Goldman Sachs data cited by The Guardian put AI stocks at over 40% of China and Hong Kong market value.
  • Robot-maker Unitree's shares have halved since its August listing.
  • The US has banned Chinese humanoid robots on national security grounds and is considering curbs on Chinese data-centre components.

What drove the sell-off

The Guardian attributes the decline to several pressures: Chinese consumers remain reluctant to spend, leaving many technology firms struggling to turn a profit, while Washington has banned humanoid robots from China and is thought to be weighing restrictions on Chinese components in data centres.

Goldman Sachs put AI stocks at more than 40% of the combined stock market value of China and Hong Kong, The Guardian reports, so swings in the sector move the whole market. The STAR 50's 40% drop since June and roughly 20% falls in other major indexes follow a rally built on government support for AI.

Policy backdrop

Beijing has backed the sector heavily, including a 60bn yuan state-backed AI investment fund that began disbursing this month, per The Guardian. The report says robotics demand has come mainly from government agencies and research institutions rather than consumers, and that Unitree's shares have halved since its August flotation.

The Guardian reports that China has tightened rules on overseas investment, with more regulations due from 1 December, without prompting a shift into domestic markets. It adds that stimulus is not expected during the politically sensitive period before next year's party congress, and that no major Chinese AI listing comparable to Anthropic's planned IPO is on the horizon.

How much have China's stock markets lost since May?

About $2.4tn, according to Bloomberg figures cited by The Guardian. The STAR 50 technology index has fallen 40% since June, while other major Chinese indexes dropped roughly 20% over the same period.
