Markets Rally as Geopolitical Tensions Ease
U.S. markets opened the week on a positive note. Easing tensions between the United States and Iran gave investors more confidence to move back into stocks.
Technology, financial and consumer stocks all moved higher. Demand for safe-haven assets dropped as the threat of a wider Middle East conflict appeared to ease.
The rally came after weeks of uncertainty had kept many investors on the sidelines.
Oil Prices Drop Sharply
Brent crude recorded one of its steepest single-day falls of the year. The drop came after fears of disruption to shipping through the Strait of Hormuz eased.
Lower oil prices reduce costs for businesses across transport, manufacturing and retail. That tends to ease inflation pressure and gives central banks more room to cut interest rates.
Cheaper crude could keep improving sentiment if prices stay low going into the second half of the year.
Nvidia Backs a $250 Billion AI Data Centre
Nvidia is reportedly helping to finance a massive OpenAI data centre project in Ohio. The deal is valued at up to $250 billion, according to reports.

The project would expand AI computing capacity to meet growing demand for advanced AI models and cloud services.
The announcement puts Nvidia at the centre of AI infrastructure, going beyond chip design into the physical systems that power artificial intelligence.
Big Tech Earnings Week Begins
This week is one of the busiest of earnings season. Microsoft, Apple, Amazon and Meta are all due to report results in the coming days.
Investors are focused on cloud growth, advertising revenue, AI spending and guidance for the rest of 2025. After mixed reactions to Alphabet and Tesla earnings, forward guidance is seen as especially important.
Strong results from these four companies could give the broader market a boost heading into August.
Airline Stocks Surge on Lower Fuel Costs
Airline shares were among the best performers of the day. Delta Air Lines, United Airlines and American Airlines all climbed as oil prices fell.
Fuel is one of the biggest costs for airlines, so a drop in crude prices can quickly improve their profit outlook if passenger demand stays strong.
Investors moved quickly into the sector, showing how fast market leadership can shift when energy prices move.
