The world’s most valuable technology companies—collectively known as the “Magnificent Seven”—endured a devastating week that ranks among their worst performances in years, obliterating more than $850 billion in shareholder wealth. The widespread destruction extended beyond tech, impacting everything from traditional equities to digital assets.
Meta suffered a staggering decline of over 11% throughout the week, marking its most severe downturn since October 2025. The social media behemoth, along with Google parent company Alphabet, faced a jury verdict holding them responsible for inadequate protection of minors using their services. Alphabet wasn’t spared either, closing out the week with losses approaching 9%.
Microsoft experienced a 6.5% weekly slide, putting the software titan on track for its most disastrous quarter since the 2008 financial crisis. The broader software sector has absorbed substantial punishment during this downturn.

Nvidia and Amazon each surrendered approximately 3% over the five-day period. Tesla wasn’t far behind, declining nearly 2%.
The Forces Behind Tech’s Massive Selloff
Treasury yields surged throughout the week as market participants recalibrated their inflation forecasts, driven partly by climbing crude oil prices. This fundamental shift has completely erased expectations for Federal Reserve interest rate reductions. Traders now view a 2026 rate increase as more probable than any cut.
Such conditions prove particularly toxic for growth-oriented equities, which typically depend on accessible capital and future profit projections that diminish in value when interest rates climb.
The semiconductor industry faced additional turbulence midweek after Alphabet unveiled groundbreaking research detailing an algorithm capable of slashing AI memory requirements. This development hammered memory chip manufacturers like Sandisk and Micron Technology on Thursday. While both companies finished the week lower, the sector managed a partial Friday rebound.
The S&P 500 has now surrendered more than 7% since January 1st. The Nasdaq has officially entered correction territory. The VIX volatility index—commonly referred to as Wall Street’s fear indicator—breached the 30 level, reaching its highest point in twelve months.
Cryptocurrency and Traditional Safe Havens Under Pressure
Bitcoin currently trades near the $65,000 threshold, significantly below its previous peak levels. Gold has similarly retreated, falling approximately $500 from its January all-time high.
Investors have found precious few refuges during this market turbulence. Even international equities are lagging behind their American equivalents.
Torsten Sløk, chief economist at Apollo, suggested markets are experiencing an excessive reaction and predicted the current volatility cycle should persist for roughly four to six weeks before conditions normalize. Meanwhile, Truist Wealth’s chief investment officer Keith Lerner advised clients that “measured cash deployment is warranted” during this period.
Apple emerged as the sole winner among the Magnificent Seven, managing to close the week marginally higher. Reports surfaced that the iPhone maker intends to expand its Siri voice assistant’s compatibility to include AI services beyond its existing OpenAI partnership.
At the most recent market close, the S&P 500 registered 6,368, reflecting a 1.67% Friday decline.
