US Stock Market Loses $2.5 Trillion Following Tech Sell-Off Amid AI Infrastructure Concerns

Concerns over a possible slowdown in artificial intelligence-related investments wiped out around USD 2.5 trillion in US stock market value on Thursday. A sharp sell-off in technology stocks erased the post-election rally that Wall Street experienced earlier in the week, according to reports.

The market downturn followed fears that gains by the Democratic Party in the US midterm elections could lead to regulatory restrictions on data centre expansion, potentially slowing down the country’s artificial intelligence infrastructure development.

The technology-heavy Nasdaq Composite suffered its worst single-day fall since April 2025, when US President Donald Trump announced sweeping global tariffs. The decline also dragged down broader market indices, with the S&P 500 and Dow Jones Industrial Average recording their worst trading sessions since April 2025.

The Nasdaq plunged 5.52 per cent to close at 24,315.00, falling more than 10 per cent below the record level reached last month and entering correction territory. The S&P 500 declined 4.36 per cent to settle at 7,353.73, while the Dow Jones Industrial Average dropped 1,833.06 points, or 3.44 per cent, to close at 51,523.06.

These sharp losses completely erased the gains made during Wednesday’s post-election rally. During that session, the Dow had surged more than 1,500 points in its best trading day since April 2025, while the S&P 500 and Nasdaq had each gained more than 1 per cent.

Initially, investors had driven up shares of major technology companies—including Amazon, Meta, and Google—on expectations that new restrictions might curb their spending on data centres, free up cash, and improve profitability. However, investors reversed those positions on Thursday amid rising concerns that proposed restrictions could ultimately harm the technology sector.

Semiconductor companies and businesses linked to data centre infrastructure witnessed heavy selling pressure. Broadcom shares fell 10 per cent, Nvidia declined 9 per cent, and Oracle dropped almost 7 per cent.

Keith Lerner, Chief Investment Officer at Truist Advisory Services, characterized the volatile market movements as a knee-jerk reaction rather than a clear indication of long-term technology stock performance under Democratic control of Congress.

The sharp market correction highlights growing sensitivity among investors regarding the future pace of artificial intelligence infrastructure investments in the United States, as data centre expansion and related technology spending remain central market focuses.

"This sharp market correction demonstrates how heavily technology valuations depend on regulatory stability and continuous infrastructure investment. For the broader tech and AI ecosystem, policy shifts can trigger rapid sentiment reversals among institutional investors. Stakeholders must monitor regulatory developments closely, as infrastructure spending directly influences the growth trajectory of semiconductor and data centre markets." — Dr. Shishir Gupta, Founder & CEO, StartupLanes
