Intel Plunges Near 30% on Worst Day Since 1974; Amazon Falls on AI Spending Scrutiny

The Quick Take

• Intel shares fell nearly 27%, on track for the chipmaker's worst single-day decline since 1974.
• Amazon shares also declined as investors raised concerns over rising AI infrastructure spending and weak free cash flows.
• AI-related and semiconductor stocks bore the brunt of a broad technology selloff amid heightened earnings scrutiny.
• The selloff raised questions about the near-term return on investment from massive AI capital expenditure programmes.

Intel Corporation's shares fell close to 30%, the chipmaker's steepest single-day decline in over five decades, following earnings results that underscored its ongoing competitive struggles in semiconductors. Amazon.com simultaneously fell as investors questioned the sustainability and near-term returns from aggressive AI infrastructure spending. The dual selloff triggered a broad-based technology sector correction, with AI-adjacent names across chip design, cloud, and infrastructure facing multiple compression as optimism about immediate AI monetisation gave way to concerns about capital intensity and profit timelines.

Intel's collapse reflects deep structural concerns about its foundry transition, execution risks in the advanced node roadmap, and intensifying competition from TSMC, AMD, and NVIDIA in both logic and AI chip markets. The Amazon selloff amplifies the AI-spend anxiety thesis building across the hyperscaler universe — Microsoft, Alphabet, and Meta also face rising scrutiny over when AI capital expenditure will translate into commensurate revenue. Peer semiconductor companies and AI infrastructure suppliers globally face negative read-through sentiment, potentially triggering a valuation reset across the broader sector.

The key macro variable is the pace of AI monetisation — specifically whether hyperscaler AI products generate enough revenue growth to justify sustained capex increases. Watch Intel's formal Q3 2026 earnings call for detail on the foundry turnaround timeline and Intel 18A node development. For Amazon, AWS revenue growth in Q3 and Q4 guidance will be the clearest signal on whether AI infrastructure investment is converting to cloud revenue. Broader semiconductor earnings — including NVIDIA, AMD, and TSMC — will calibrate whether the Intel selloff is company-specific or a sector-wide repricing event.
