The market reaction follows the Democrats taking control of Congress following the US midterm elections.

They won both the US Senate and House of Representatives in Tuesday’s midterms, taking control of Congress for the rest of President Donald Trump’s presidency.

The Democrats’ success sparked concerns from some over a potential slowdown in the development of artificial intelligence (AI) – with investors appearing to be worried about the prospect of tougher regulation.

Democratic candidates across the US had campaigned on slowing the growth of AI, and on opposition to the data centres that are vital for powering the technology.

For example in Texas, where governor-elect Gina Hinojosa campaigned heavily against data centres, pledging a moratorium on new construction in the sector.

US President Donald Trump, by contrast, has publicly backed the technology – even calling for it to be renamed “super intelligence”.

There were also dozens of measures on ballots around the country aimed at restricting the development of the centres.
