President Donald Trump‘s trip to Saudi Arabia earlier culminated in a $600-billion investment deal with the Kingdom that the administration is touting as a historic milestone for both countries.

While certain details of what is included in the investment package remain elusive, the White House has said that the deals secured during Trump’s trip to Riyadh “represent a new golden era of partnership,” and will foster “economic ties that will endure for generations to come.”

What is the $600 billion Trump-Saudi deal?

In a summary of the deal released on Tuesday, the White House said that Saudi Arabia had made a “$600 billion commitment to invest in the United States.”

It listed a number of private investments promised by Saudi firms, including a $20 billion commitment from DataVolt to establish “AI data centers and energy infrastructure” in the U.S. The list included several partnerships between Saudi and U.S. companies including Google, Uber and Boeing, the latter securing a $4.8 billion order for 737s from a Riyadh-based aircraft lessor.

Multiple American firms have also reportedly agreed to assist in Saudi infrastructure projects, such as the King Salman International Airport and Qiddiya City. The White House said that these projects will total “$2 billion in U.S. service exports.”

As noted by The New York Times, many of the listed investments were short on specifics, and together amounted to less than half the headline, $600-billion figure, though the White House said that the published investments were “just a few of the many transformative deals secured in Saudi Arabia.”

Newsweek has reached out to the White House via email for a full list of the investments included in the $600 billion deal.

In addition to the White House’s announcement, several companies announced deals with Saudi firms during Trump’s visit to the Kingdom. Nvidia, whose CEO Jensen Huang met with Trump and Crown Prince Mohammed bin Salman during the Saudi-U.S. Investment Forum, announced it would be partnering with Humain, an AI startup owned by the Kingdom’s sovereign wealth fund, and sending 18,000 chips to the country to power AI projects.

Amazon Web Services, similarly, announced a partnership with Humain to invest over $5 billion in the creation of an “AI Zone” in Saudi Arabia, which it said will advance the country’s mission to “be a world leader in AI.”

What sectors are involved?

The details published by the White House showcase an agreement that spans several sectors, many of them emerging in both the U.S. and Saudi Arabia. Alongside several investments in AI infrastructure, there is a private investment of $80 billion from U.S. and Saudi firms aimed at developing “cutting-edge transformative technologies in both countries,” though these are not specified.

In addition, “investment partnerships” were announced focused on U.S. energy and sports, as well as the formation of a New Era Aerospace and Defense Technology Fund. These, the White House said, will channel “substantial capital into American industries, driving innovation, and creating high-quality jobs across the United States.”

Folded into the wider investment package is a significant, $142-billion arms deal—dubbed the “largest defense sales agreement in history.” The package will equip Saudi Arabia with “state-of-the-art warfighting equipment and services” from more than a dozen U.S. companies. According to the White House, these will help to modernize Riyadh’s air force and space capabilities, air and missile defense, maritime security, border security and land forces modernization, and information and communication systems.

“The package also includes extensive training and support to build the capacity of the Saudi armed forces,” the fact sheet read, “including enhancement of Saudi service academies and military medical services.”

Why does this matter?

In addition to the significant levels of investment the White House claims to have secured, the deals that have been struck come at a critical time for Trump, whose foreign policy is now focused on striking a deal with Iran over its nuclear program, as well as the ongoing destruction of Gaza—two areas of geopolitical importance for Saudi Arabia.

“The U.S.-Saudi relationship has been a bedrock of security and prosperity,” Trump said during his speech at the investment summit. “Today, we reaffirmed this important bond, and we take the next steps to make our relationship closer, stronger and more powerful than ever before.”

How have Trump and his allies responded to the deal?

President Trump, during his address in Riyadh, said: “In addition to purchases of $142 billion of American-made military equipment by our great Saudi partners, the largest ever, this week there are multibillion dollar commercial deals with Amazon, Oracle, AMD—they’re all here—Uber, Qualcomm, Johnson & Johnson and many, many more. So, I want to congratulate everybody.”

Trump continued: “In the United States, we’ve launched the Golden Age of America. It’s the golden age. We see it. We see it with all that money, trillions and trillions of dollars pouring in, hundreds of thousands of jobs coming in with it. And with the help of the people of the Middle East, the people in this room, partners throughout the region, the golden age of the Middle East can proceed right alongside of us. We will work together.”

The White House said: “The deals celebrated today are historic and transformative for both countries and represent a new golden era of partnership between the United States and Saudi Arabia.

“Leading up to this historic deal, President Trump had already secured trillions in U.S.-based investments, setting the stage for a new era of American prosperity,” it added.

Saudi political commentator and author Ali Shihabi, as quoted by Bloomberg, said: “The visit is highlighting the strength of the relationship and adding ballast by creating a continuously expanding web of ties in the economic, political and security fields.”

What people are saying?

Bernard Haykel, professor of Near Eastern Studies at Princeton University, told PBS: “They certainly were able to secure major arms deals and also a major agreement on artificial intelligence. But I think the American administration’s principal goal has been to—and Saudi Arabia’s principal goal has been to forge a strategic alliance because the Americans don’t want the Saudis to veer toward China, especially when it comes to technology and A.I.

“And I think that relationship, that strategic relationship, has been very strongly solidified with this visit of President Trump.”

Wedbush Securities analysts, in a note shared on Wednesday, wrote: “The theme was clear in Riyadh … the AI Revolution is coming to the Saudi Kingdom and Riyadh will be a major buyer of AI chips, software, autonomous/robotics, and data centers over the next decade. Coming off a major U.S./China trade deal/pause this weekend in Switzerland which was a “dream scenario” for the markets and bullish tech investors, the tone in Riyadh has been about the bright green light on the massive AI build out in Saudi and this could open up a huge opportunity and TAM for Nvidia, Palantir, Microsoft, Amazon, Alphabet, Tesla and many other well positioned chip/software names over the coming years.”

“This will be just the beginning as tech players such as the hyperscalers, Palantir, Tesla and others see the game changing AI market opportunity in the Middle East and we expect bigger AI deals on the horizon,” they added.

What happens next?

President Trump has continued his Gulf tour with a visit to Qatar, where the focus remains on attracting investment to the U.S. The three-nation trip will end with a visit to the United Arab Emirates later this week.
