# Nasdaq 100 falls 5.5% this week, its biggest weekly drop in 18 months
**The Nasdaq’s biggest weekly drop in 18 months isn’t a hit to AI demand—it’s a hit to AI’s “wallet”**
$BTC $ETH
The Nasdaq 100 fell 5.5% this week, closing at 29,187—its biggest weekly drop since the tariff turmoil in April 2025. The Philadelphia Semiconductor Index fell for eight straight sessions (its longest losing streak since 2008), dropping about 16% and wiping out roughly $2 trillion in market value. U.S. tech stocks lost more than $3 trillion in value in 10 days.
Let’s break down the four drivers behind this move using PEST:
P (Political): The 10-year Treasury yield topped 5.1%, cooling rate-cut bets and putting pressure on growth-stock valuations.
E (Economic): September PPI rose 6.3% year over year, above expectations. Add Brent crude nearing $110 and WTI up 4.2% for the week, and inflation expectations are heating up again.
S (Sentiment): The AI trade is overcrowded. Profit-taking turned into a rush for the exits, and retail sentiment has turned bearish.
T (Technology/Industry): The real epicenter. Yields on some CoreWeave bonds briefly topped 15%, and the company’s total debt exceeds $51 billion. The market’s focus has shifted from “How strong is demand for computing power?” to “Can the returns justify borrowing this much?”
Follow the 5 Whys to the bottom: Nasdaq falls → semiconductors lead the decline → financing costs for AI infrastructure are being repriced → the trigger is oil prices, PPI, and earnings-season scrutiny → at its core, the AI narrative is shifting from a “demand story” to a “balance-sheet story.”
How has crypto reacted? BTC is down 2.6% this week and ETH 4.0%, both less than the Nasdaq—so they’ve held up relatively well. One correction to a common misreading: Strategy’s 9.2% drop on Friday was due to an MSCI index adjustment (risk to its eligibility as an index constituent), not because of Bitcoin. BTC fell only about 1% that day.
In commodities: gold -0.1% ($4,186; already near highs, and it didn’t attract safe-haven buying), silver -4.4%, and oil +4.2%. See the chart for details.
The key point in one sentence: This sell-off is repricing the “AI burn-rate model,” not AI demand itself. If companies can show AI revenue this earnings season, sentiment will recover; if they can’t, the semiconductor sector’s eight-session losing streak may just be the beginning.
Do you think BTC can keep outperforming the Nasdaq during this U.S. stock-market correction? Share your thoughts in the comments.
