NVIDIA Corp. shares jumped more than 3% in morning trading Tuesday, climbing toward $170.80 as investors welcomed signs of potential de-escalation in the U.S.-Iran conflict and bet on continued explosive demand for the company's artificial intelligence chips.

The stock rose $5.63, or 3.41%, shortly after the market open on March 31, 2026, helping lift broader tech indexes. The move followed a choppy March in which NVIDIA shares had faced pressure from elevated oil prices and supply chain worries tied to Middle East tensions, but analysts maintained that the company's dominant position in AI infrastructure positions it for long-term gains despite near-term volatility.
