Almost **$1 trillion** has been erased from the value of **Wall Street’s largest technology companies** this week, as investors grow increasingly wary of **soaring valuations linked to artificial intelligence**.

The so-called **Magnificent Seven** — **Nvidia, Tesla, Alphabet, Amazon, Meta, Microsoft** and **Apple** — have borne the brunt of the sell-off, which traders say reflects mounting scepticism over whether **AI investment enthusiasm** is justified by underlying profits.

**Nvidia**, which last month became the world’s first **$5 trillion company**, fell a further **2.3%** in early New York trading and has shed **nearly $500 billion** in market value this week alone.

Collectively, losses across the Magnificent Seven have reached **$953.7 billion (£724.5 billion)**. The **Nasdaq Composite**, the world’s leading tech index, is heading for its **worst week since Donald Trump’s April tariff onslaught**, down **3.9%** so far.

The sell-off comes as traders question whether **AI firms’ ambitious spending plans** can be supported by revenue growth. **OpenAI’s $1.4 trillion, eight-year investment blueprint**, underpinned by a **$100 billion partnership with Nvidia**, has underscored concerns about **the scale of capital being deployed** relative to earnings.

**Sam Stovall**, chief investment strategist at **CFRA Research**, said:

> “There is a continuation of concern about a possible pullback — it’s traditional early-November weakness triggered by elevated valuations and a lack of fresh catalysts to support the market.”
