AMD surged 8% to a record near $558, breaking a $900 billion market cap, after unveiling its Ryzen AI Halo developer platform priced at $3,999, undercutting NVIDIA's DGX Spark by $700 while matching its 200-billion-parameter ceiling with 14% better performance. NVIDIA climbed 4% and Intel rose 3% as the chip sector rallied on a broad risk-on move, with the market treating local AI inference as additive rather than competitive. Wall Street upgraded AMD targets following the announcement, with Citi raising its price target to $575.

Palantir rose 5% to $134.70 and Cloudflare gained 3% to $236.97 on Monday amid a broad risk-on rally triggered by a U.S.-Iran peace deal announcement. Both stocks, which operate in AI infrastructure and security, amplified gains as investors rotated back into higher-beta growth names. The moves were macro-driven rather than company-specific, with no identified catalysts tied to either firm's operations.

SpaceX's NASDAQ debut is driving a sector rally, with the company's stock up 16% to $187 on its second trading day after pricing at $135. Rocket Lab gained 7% on the SpaceX halo effect and strong Q1 results, while Virgin Galactic fell 4% due to dilution concerns from a debt-to-equity swap and a 51% revenue decline. The divergence reflects investor appetite for established space operators versus execution risk at earlier-stage players.
