Big Tech stocks came under pressure this past week as investors pulled back from some of the market’s biggest artificial intelligence winners. Higher bond yields, renewed inflation concerns, and sector-specific developments all added to the move lower.
The sell-off left the “Magnificent Seven” with more than $850 billion in erased market value over five trading days. The group, which includes Apple, Microsoft, NVIDIA, Amazon, Tesla, Meta, and Alphabet, has now faced a broader reset after leading the market for much of the past three years.
The retreat in large technology stocks came as markets reacted to rising oil prices and stronger concerns that inflation may remain elevated for longer. As a result, investors reduced expectations for interest rate cuts, which added pressure to growth-focused sectors.
Higher Treasury yields also weighed on technology names because future earnings become less attractive when borrowing costs stay high. Therefore, stocks tied closely to long-term AI spending and expansion plans were among the hardest hit during the week.
At the same time, the NASDAQ 100 moved deeper into a correction phase, reflecting the broader weakness in high-growth companies. Although some semiconductor names recovered on Friday, the rebound was not enough to reverse the week’s overall losses.
Meta posted its worst weekly performance since October 2025, falling more than 11%. The drop followed a landmark social media lawsuit in which a jury found Meta and Alphabet negligent for failing to protect young users on their platforms.
Alphabet also ended the week sharply lower, closing down nearly 9%. The court decision added fresh pressure to both companies at a time when investors were already rethinking risk across major technology stocks.
Microsoft also recorded a steep decline, ending the week down 6.5%. The stock is now on track for its weakest quarter since 2008, showing how software shares have been hit during the current market reset.
Chipmakers and AI-linked stocks also faced pressure after Alphabet released new research on an algorithm designed to reduce AI memory usage. This development unsettled memory-related semiconductor stocks and contributed to wider weakness across the chip sector.
Although NVIDIA and Amazon fell by a smaller margin than some of their peers, both still ended the week lower. NVIDIA lost roughly 3%, while Amazon posted a similar decline. Tesla also finished the five days down nearly 2%.
Other semiconductor names also struggled. Sandisk and Micron remained in the red for the week, even after Friday’s partial recovery. Therefore, the pressure extended beyond the largest tech firms and into the broader AI supply chain.
Apple was the only Magnificent Seven stock to finish the week slightly higher. The move followed a report that the company plans to open Siri to outside artificial intelligence services beyond its current partnership with OpenAI’s ChatGPT.
Even so, the broader picture remains weak for the group in 2026. All seven Magnificent Seven stocks are down this year, and each has also trailed the S&P 500.
Investors are also watching the scale of AI spending more closely. Amazon, Microsoft, Alphabet, and Meta are expected to spend close to $700 billion in capital expenditures this year, much of it tied to AI infrastructure. This has added to concerns about how long it may take for those investments to produce returns.
