US equity markets opened higher on Thursday, with semiconductor shares leading the advance.

The technology sector's strength helped offset broader market pressure stemming from a new escalation in hostilities between the United States and Iran, which has reignited concerns over energy supply and global trade routes.

The divergence within the tech sector is becoming more pronounced.

While hardware and chipmakers have benefited from a flight to tangible assets and continued demand for AI infrastructure, software stocks have seen a sharp rise before Monday's market open driven by Nvidia CEO Jensen Huang's announcement of plans for a new chip designed to power personal computers.

This development has triggered a broader rally in related names, highlighting the market's focus on specific catalysts rather than broad sector momentum.

The geopolitical backdrop remains volatile.
