A massive global market rout deepened on Friday as investors reacted to US midterm election results that suggest a shift in policy toward artificial intelligence. The selloff, which began on Wall Street, quickly spread to major financial hubs in Asia and Europe, leading to one of the most significant downturns for tech-heavy indices in recent years.
Following the success of several anti-AI candidates in the United States, concerns regarding the long-term profitability and regulatory environment of the AI industry have intensified. This political shift has triggered a wave of red across global tickers, erasing trillions of dollars in market value within a single trading cycle.
Tech Sector Faces Massive Value Losses
The impact on US markets was immediate and severe on Thursday. The Nasdaq 100, an index heavily weighted toward technology firms, saw $2.3 billion in market value vanish as it plummeted 6.3%. The broader S&P 500 fared even worse in terms of total valuation, losing $2.8 trillion in value after a 4.4% drop.
This decline marks the worst single-day performance for these indices in 18 months. The last time markets saw volatility of this magnitude was when global tariffs under the Trump administration caused significant investor anxiety. While US futures showed a mixed performance early Friday, the momentum of the selloff had already moved into international markets.
Asian Markets Plunge into Bear Territory
Asian markets bore the brunt of the tech stock selloff during Friday's trading session. In Japan, the Nikkei 225 index dropped by 6%, officially entering bear-market territory. This past week has been recorded as the worst for the Nikkei since 2020.
In South Korea, the Kospi index experienced a tumble of more than 8%, a move so sharp it triggered a temporary market-wide trading halt. Key players in the AI supply chain were hit particularly hard:
- Samsung and SK Hynix, both major suppliers of memory for AI data centers, saw their share prices plunge over 10% before seeing a slight recovery.
- In Taiwan, the TAIEX index fell by 9%, largely due to the vulnerability of critical chip suppliers like TSMC.
- London's FTSE 100 opened 1.6% lower, with similar downward trends seen in the French CAC40 and German DAX indices.
Political Shift and AI Infrastructure Concerns
The primary catalyst for the US midterm election impact on the markets appears to be the rise of a new group of politicians skeptical of rapid AI expansion. One notable victory was that of Governor-elect Gina Hinojosa in Texas, which currently serves as the largest market for data centers in the country.
Investors are concerned that a Democratic-controlled Congress could implement stricter oversight on AI infrastructure projects. Such scrutiny is expected to lead to project delays and increased operational costs, casting doubt on whether current investments in AI will remain profitable.
Charu Chanana, Chief Investment Strategist at SAXO Markets, noted that "Markets are being punished according to their dependence on the U.S. AI infrastructure cycle." This sentiment was echoed by Tai Hui, APAC Chief Market Strategist at J.P. Morgan, who stated that companies in Taiwan, Japan, and South Korea are "clearly highly linked to the global AI capex cycle."
A Rollercoaster Year for AI Stocks
This recent Nasdaq 100 plunge is a sharp reversal from the performance seen earlier this year. In June, many Asian investors saw their portfolios grow significantly during a period of intense optimism surrounding the AI boom. However, the current downturn has erased many of those gains, leaving investors to navigate a volatile environment where political developments in Washington directly dictate the value of global tech holdings.
