Internet Stocks Slide 18% in 2026 Despite Broader Market Gains

Large-cap internet stocks fell by an average of 18% in 2026, lagging broader benchmarks like the S&P 500 and Nasdaq Composite amid rising artificial intelligence disruption fears and stretched valuations, according to Evercore ISI data published on Sunday, October 11, 2026.

### Tape / Session Read Evercore ISI Senior Managing Director Mark Mahaney pointed to six primary "Bear Market Factors" behind the sector's underperformance: stretched valuation exits following a multi-year bull run, terminal value and AI disruption risks impacting platforms like Booking Holdings, Expedia Group, Shopify, and Uber Technologies, and mounting capital expenditure intensity at major hyperscalers.

Additional headwinds include Middle East energy shocks from the ongoing war in Iran, upcoming IPO supply reallocations, and the emergence of autonomous AI agents—termed "Muse Risk"—threatening incumbent platform control over customer relationships and ad monetization.

### Why This Lane Matters Persistent market skepticism regarding massive AI infrastructure spending has weighed heavily on internet equities, even as research suggests potential free cash flow inflections over the next three to 12 months could shift sentiment for major hyperscalers.

## Technical Analysis & Key Risk Watch

With market breadth divided between surging index benchmarks and lagging internet equities, traders are monitoring fundamental inflection points against expanding capital expenditure cycles in fiscal 2027 and 2028.
