A high-powered list of business leaders is joining Trump at lunch in Riyadh.

Joining President Trump and top U.S. and Saudi officials for lunch in Riyadh on Tuesday are dozens of business leaders from some of America’s largest companies.

The executives — from tech firms, banks, consumer groups and other industries, including representatives of four of the 10 biggest U.S. companies by market value — may be there to pitch for business from deep-pocketed Saudi investors, businesses and government departments. Their companies are also dealing with the tariffs imposed by Mr. Trump on U.S. trading partners, so the trip is an opportunity to lobby top Trump officials, such as Treasury Secretary Scott Bessent and Commerce Secretary Howard Lutnick, on trade policy.

Saudi Arabia has emerged as one of the world’s largest investors in artificial intelligence, an effort to diversify the oil-rich nation’s economy and give it influence over one of the hottest sectors in the business world. Notable A.I. players at the lunch include Sam Altman, the chief executive of ChatGPT parent OpenAI; Jensen Huang, the leader of the advanced chipmaker Nvidia; Ruth Porat, the chief investment officer of Alphabet, Google’s parent company; and Andy Jassy, the chief of Amazon, which is a major provider of cloud-computing services.

There is also Elon Musk, who, in addition to overseeing Mr. Trump’s effort to slash the size of the federal government, also runs Tesla, SpaceX and his own A.I. company called xAI, which is in talks for new financing that could value the firm at as much as $120 billion.

The vast sums of money that Saudi Arabia is spending on technology, infrastructure and other priorities have made the country a popular destination for financial executives seeking to advise the kingdom and its companies. Top financial leaders at the lunch include Stephen Schwarzman of Blackstone, Larry Fink of BlackRock and Jane Fraser of Citigroup.
