TL;DR
A Wall Street sell-off led by technology and semiconductor stocks spread across global markets, sending Asian and European indexes lower. US shares steadied at the next opening, but investors remained concerned about heavy spending on AI, concentrated exposure to a small group of technology companies and potential limits on data-centre development. The report does not establish that the election caused the sell-off.
A sell-off in US technology shares spread across global markets, driving steep losses in Asia and Europe after the Nasdaq fell 5.5% and the S&P 500 dropped 4.4% in the prior session, according to This Is Money. Wall Street then showed signs of stabilising: at the next opening, the Nasdaq was up 1.32% and the S&P 500 had gained 0.36%, though the gains did not reverse declines elsewhere.
Losses were sharpest in several Asian markets. Japan’s Nikkei 225 fell 6%, its steepest one-day drop since April 2025, while South Korea’s and Taiwan’s indexes fell more than 8% at the open, the report said. The report does not specify the exact percentage change for either of those two indexes beyond that figure.
European markets also declined. London’s FTSE 100 dropped more than 200 points, or 1.96%, to 10,571, after reaching 10,948 on Thursday. Germany’s DAX fell 2.2%, and France’s CAC declined 1.76%. The FTSE’s fall included companies across different sectors: Glencore was down 2.7%, while Airtel Africa and AstraZeneca each lost 2.5%.
The US sell-off hit individual technology and chip companies particularly hard. The report said Tesla fell 11%, Nvidia lost 8%, and shares in Advanced Micro Devices, Micron Technology and SanDisk fell nearly 15%, 14% and 17%, respectively. It also reported that SpaceX shares fell 9%, though it did not provide details about the trading venue or period for that figure. The Nasdaq dropped as much as 6.4% early in the session before closing down 5.5%.
How the Tech Sell-Off Spreads
The losses matter beyond investors who own individual technology shares. Funds that track indexes such as the Nasdaq and S&P 500 hold exposure to large US companies, so a decline in the indexes can reduce the value of pension and savings investments tied to them. The report says the impact will vary depending on each portfolio’s holdings; it does not quantify the losses to household savings.
The sell-off also highlights the market’s reliance on a relatively small group of technology and semiconductor companies. Stuart Clark of Quilter said those firms carry substantial weight in US equity indexes, meaning weakness in a handful of names can translate into larger index declines. That concentration can also transmit investor unease into other markets, even where local indexes have less direct exposure to AI companies.
For the companies involved, falling share prices arrive as investors question whether the money being spent on AI infrastructure will produce adequate returns. The report describes those questions as part of the market mood, not evidence that the investments will fail. It also says concerns about opposition to data centres may be affecting expectations for future development.

Election Concerns and AI Spending
The report links the market anxiety to two concerns: whether spending on AI infrastructure can be justified by future returns, and whether political opposition to data centres could slow development. It says traders grew jittery after Democrats won the midterm elections, but it does not establish that the result directly caused the stock declines. The share sell-off and election outcome occurred close together; causation remains uncertain.
Markets had briefly rallied after the election before a sharp reversal on Wall Street. The report said the volatility gauge known as the market’s “fear gauge” reached its highest level in seven months, and that roughly £2 trillion was wiped off the Nasdaq’s value on Thursday. These are figures reported for that session, not a measure of losses across all global markets.
Investors had poured large sums into technology firms amid expectations that AI demand would support future growth. The latest declines reflect a reassessment of valuations and spending plans, but the report does not provide company-by-company forecasts or evidence that the AI investment cycle has ended.
„Market rebounds can happen quickly and those sitting on the sidelines often miss the best days.“
— Dan Coatsworth, head of markets at AJ Bell
What Is Driving Investor Anxiety
The cause of the sell-off is not settled. The report describes concerns about AI valuations, infrastructure spending, possible opposition to data centres and the election outcome, but does not show how much each factor contributed. Trump blamed the election result, while that remains his stated explanation rather than an independently verified cause.
It is also unclear whether the next gains in US trading mark a lasting recovery or a temporary pause. The report gives mixed futures expectations for US indexes and does not provide subsequent closing figures. Forecasts and intraday movements can change as trading continues.
The report does not quantify the effect on individual pension accounts, specify how investors’ portfolios are allocated, or establish whether data-centre development will face new restrictions. Oil prices also moved amid questions about the Middle East conflict, but the report does not confirm that a change in the conflict or policy followed.
The Next Sessions and AI Outlook
Investors will watch whether the Nasdaq and S&P 500 can hold their early gains and whether declines continue in Asian and European markets. The available report describes a mixed picture in futures, with further falls expected for the Dow Jones and S&P 500 and a small rise indicated for the Nasdaq; those expectations are not confirmed market outcomes.
Attention is also likely to remain on technology companies’ spending plans and evidence that AI-related infrastructure can generate returns. Political developments affecting data-centre construction could influence expectations, but the source material does not identify a specific decision or timetable to watch.
For investors, the immediate market direction and the longer-term effect on savings remain uncertain. The report cites advisers who caution that rebounds can occur quickly, but offers no assurance that markets will recover on a particular schedule.
Key Questions
What happened to global stock markets?
After sharp losses on Wall Street, Asian and European indexes fell. Japan’s Nikkei 225 lost 6%, while the FTSE 100 fell 1.96% to 10,571. US markets showed early gains at the next opening, with the Nasdaq up 1.32% and the S&P 500 up 0.36% at that point.
Why did technology shares fall?
The report identifies investor concerns about high AI-related valuations, large infrastructure spending, possible opposition to data centres and the midterm election result. It does not establish how much any one factor caused the declines.
Did the election cause the market sell-off?
President Donald Trump blamed the Democrats’ election victory, but the report does not independently establish that link. It describes the result as one concern among several weighing on investors.
Could the sell-off affect pensions and savings?
It could affect investments linked to US indexes such as the Nasdaq and S&P 500, including some pension and savings funds. The actual impact depends on each account’s holdings, and the report does not estimate losses for individual savers.
Is the market decline over?
That is not yet clear. Wall Street showed early gains after the previous session’s declines, while futures expectations were mixed. The report does not provide later closing results or a confirmed forecast for a recovery.
