Magnificent Seven Stocks: Over $1,000 Billion Lost in a Single Session

On Thursday, November 5, the “Magnificent Seven,” the seven largest US tech companies listed on Wall Street, together lost more than $1,000 billion in market value. According to AGI, the total loss was about $1,130 billion, the biggest in a single day for the group.¹² It was Wall Street’s worst session since April 2025, two days after the midterm vote, the mid-term elections, which gave the Democrats the House and the Senate.¹²

How much did the individual stocks lose?

The steepest drop was Tesla’s, at -10.8%. It was followed by Nvidia (-9.3%), Meta (-4%), Microsoft (-3.6%), Alphabet and Amazon (both -2.2%) and Apple (-1.5%).¹ The group had gained a lot the day before, after the vote. Thursday’s session wiped out the $600 billion accumulated in that rally.¹ AGI reports that Tesla and SpaceX, the two companies run by Elon Musk, together lost $420 billion in capitalization, that is, in market value.¹

What happened to the indexes?

The tech-heavy Nasdaq index fell 5.52%, the S&P 500 fell 4.36% and the Dow Jones fell 3.44%.¹ Il manifesto calculates that in the same session the New York Stock Exchange burned through $3,200 billion. This figure covers the entire market and not just the seven companies.³ European stock markets opened sharply lower on Friday, following Wall Street and Asian markets.¹

Why were AI stocks hit?

The selling weighed most heavily on AI-related stocks, especially those in infrastructure, chips and data centers. According to AGI, investors fear that the sector will have to face new rules and difficulties in expanding the capacity of its data centers.¹ Il manifesto also writes of markets anticipating a regulatory squeeze after Trump’s electoral defeat.³

Why it matters

TechCrunch notes that the Democrats have promised more oversight of AI and that the battle is also being fought in state legislatures, in the communities that decide whether to host data centers and in the markets.⁴ The next day the Nasdaq closed higher, according to La Stampa, but investors remain worried about future data center construction projects in the United States.⁵
