US President Donald Trump and Saudi Crown Prince Mohammed bin Salman on Tuesday signed a strategic economic partnership agreement and a series of memoranda of understanding (MoUs) in Riyadh, marking a major expansion in bilateral cooperation.
According to the White House, the agreements form part of a broader $600 billion investment package spanning defense, energy, technology, infrastructure, and health.
A key component of the deals is a record $142 billion arms agreement that includes advanced US military equipment and comprehensive training for Saudi forces. Reuters described the deal as “the largest in history,” noting that discussions also included a potential Saudi acquisition of F-35 fighter jets.
The package also includes a $20 billion Saudi investment—via DataVolt—in US-based artificial intelligence data centers and energy infrastructure. In addition, $80 billion in joint tech-sector investments are planned from major companies such as Google, Oracle, Uber, and AMD across both countries.
Infrastructure agreements feature prominently, including $2 billion in large-scale Saudi projects to be implemented by US firms AECOM and Parsons. Other deals involve $14.2 billion worth of US gas turbines from FEVernova and $4.8 billion in Boeing 737-8 aircraft exports.
