Sustained enthusiasm for artificial intelligence has continued to drive major U.S. indices to new peaks. In early May 2026, both the S&P 500 and Nasdaq Composite surged to fresh record closes, supported by strong corporate earnings in the semiconductor sector and broader optimism around AI infrastructure spending.
Investors are confident that ongoing AI-related capital expenditures by hyperscalers will generate substantial long-term returns, justifying elevated valuations across tech-heavy benchmarks. This momentum has extended well beyond leading names like Nvidia, lifting a diverse group of chipmakers and AI enablers.
Advanced Micro Devices (AMD) and Intel stood out as notable fast movers this week. AMD shares jumped sharply, rising around 17-19% in a single session after the company delivered a strong Q1 earnings beat and raised its outlook significantly. The upbeat forecast highlighted robust demand for its data center GPUs and Epyc processors in AI workloads, with particular emphasis on opportunities in AI inference.
Intel also posted solid gains, building on positive momentum from its earlier Q1 2026 results that exceeded expectations on revenue and profitability. Analyst upgrades and growing confidence in Intel’s turnaround, including progress in its foundry business and potential AI CPU opportunities, helped reinforce investor sentiment.
Other tech names such as Super Micro Computer benefited from continued AI server demand, while players like Micron and Broadcom rode the broader ecosystem tailwinds.
The key catalysts driving this week’s spikes included AMD’s blockbuster earnings and forward guidance, which validated sustained AI data center growth and sparked a sector-wide rally. Geopolitical relief from progress toward a U.S.-Iran resolution and a holding ceasefire lowered risk premiums and encouraged risk-on flows into equities. Additionally, ongoing hyperscaler partnerships and signals of multi-year AI investment further strengthened the positive narrative.
