CSIS and Arab Center DC: MBS Extracted Massive US Concessions from Trump Visit — What Did the US Get?

Think tank analyses published May 16 assessed the outcomes of Trump's May 13–14 Riyadh summit with MBS, noting the Kingdom secured historic concessions while Washington received largely non-binding commitments. CSIS concluded MBS 'got a lot' — including a $142 billion arms package, removal of chip-export restrictions enabling Nvidia to supply 18,000 H100-class chips to Saudi AI startup Humain, Aramco equity deals, and Boeing commercial aircraft orders — while the US received promises of $600 billion in future investment, many of which are non-binding MOUs or projects already underway. Arab Center DC analysts noted the deals were 'transactional without strategic guarantees,' with no security treaty formalizing US commitments to defend Saudi Arabia in the ongoing Iran conflict and no measurable normalization progress with Israel. The analyses questioned whether Saudi Arabia's $142 billion arms package — including upgrades to existing F-15 fleets, air defense systems, and maritime assets — strengthened or complicated US ability to manage escalation in the Iran war.
