NVIDIA shares surged 5.6% to close at $174.40 on March 31, 2026, driven by the company's $2 billion investment in Marvell Technology, signaling deepened AI infrastructure partnerships and boosting trader confidence in sustained data center demand. This capped a volatile month, with mid-March GTC announcements of $1 trillion in Blackwell and Vera Rubin GPU orders offsetting earlier valuation concerns that briefly pushed forward earnings multiples below S&P 500 levels. Prior quarter revenue hit a record $68.1 billion, up 20% quarter-over-quarter, underscoring AI chip dominance amid robust hyperscaler spending. Traders eye late-May fiscal Q1 2027 earnings for Blackwell ramp updates, with share price dynamics tied to production timelines and competitive positioning.
