European shares opened lower and Asian shares were mostly higher Thursday after a rally on Wall Street that was led by computer chip giant Nvidia.
Oil prices rose as media reports said the likelihood was rising of U.S. conflict with Iran.
President Donald Trump has been weighing whether to take military action against Iran as his administration surges military resources to the region while holding indirect talks with Tehran over its nuclear program.
That is raising concerns that any attack could spiral into a larger conflict in the Middle East.

Nvidia helped lift the market and climbed 1.6% after Meta Platforms announced a long-term partnership where it will use millions of chips and other equipment from Nvidia for its artificial-intelligence data centers.
“No one deploys AI at Meta’s scale,” Nvidia CEO Jensen Huang said. Because his company is the most valuable on Wall Street, Nvidia’s stock was the single most powerful force pulling the S&P 500 higher.
That performance demonstrated the upside of AI development for the U.S. stock market. But investors have also focused on the potential downsides recently, which has led to sharp swings in share prices.
Meta’s stock fell as much as 1.7% before recovering and rising 0.6%.
Another worry is that if AI succeeds in creating tools to do complicated tasks more cheaply, it may undercut companies in industries as far flung as software, legal services and trucking logistics. Investors have suddenly and aggressively sold stocks of companies seen as under threat in what analysts have likened to a “shoot first-ask questions later” mentality.
Several profit reports from companies helped to lift stocks Wednesday. They continued what’s been a strong reporting season for the big U.S. companies in the S&P 500.

Such strong data could encourage the Federal Reserve to keep interest rates steady.
The Fed has put its cuts to interest rates on hold, but many on Wall Street expect it to resume later this year. The widespread forecast is that will come during the summer, after a new chair is scheduled to step in atop the Fed.
Minutes released Wednesday from the Fed’s last meeting showed many officials want to see inflation fall further before they would support additional interest rate cuts this year.
Lower rates can give a boost to the economy and prices for investments, but that comes at the cost of potentially worsening inflation.
