Qatar: Trump on Wednesday signed an agreement for investments between the two countries worth more than $243.5 billion and outlined plans to increase the investment to $1.2 trillion, the White House said.

Qatar Airways agreed to buy 210 Boeing jets worth $96 billion, representing the largest deal yet facilitated by Trump since he arrived in the Middle East, The New York Times reported.

Qatari-based Al Rabban Capital signed an agreement with the Quantinuum computing company to invest $1 billion in quantum technology and workforce development in the U.S.

The U.S. also signed several defense-related agreements with Qatar, including a $1 billion deal for Qatar to acquire drone defense technology from Raytheon RTX, and a $2 billion agreement for Qatar to purchase remotely piloted aircraft from General Atomics.

Saudi Arabia: The White House said Tuesday Saudi Arabia agreed to $600 billion in investments, though some of the projects listed were already in the works, while an additional 145 deals worth more than $300 billion were reportedly signed at an adjacent investor conference attended by several U.S. billionaires and prominent business executives.

A $142 billion agreement for the Saudis to buy military equipment and services from more than a dozen U.S. defense firms is included in the agreement Trump signed, the White House said.

The $600 billion investment also includes $20 billion from Saudi firm DataVolt for AI data centers and energy infrastructure in the U.S., and $80 billion in technologies in both countries from Google, DataVolt, Oracle, Salesforce, AMD and Uber.

More than $2 billion in work by American firms in Saudi infrastructure projects, including King Salman International Airport and the Qiddiya City entertainment complex, was also part of the agreement.

Separate from the agreement between the two governments, Elon Musk announced Saudi Arabia had agreed to use his Starlink internet satellite services for aviation and maritime shipping.

Nvidia will sell 18,000 artificial intelligence chips to the new Saudi-backed company, Humain, debuted Monday and chaired by Saudi Crown Prince Mohammed bin Salman.

American-based AMD announced a $10 billion project with Saudi Arabia to provide chips and software for AI data centers “stretching from the Kingdom of Saudi Arabia to the United States.”

Humain also announced deals with Global AI, Cisco and Amazon, which will build an “AI zone” in Saudi Arabia, including new AI infrastructure and servers, and networks to facilitate more efficient AI training, the company said.
