Recent diplomatic momentum has slowed following Kazakhstan’s formal accession to the Abraham Accords in November 2025, the most recent addition. Saudi Arabia, widely viewed as the pivotal prospective participant, continues to condition normalization on concrete progress toward a Palestinian state, a stance reiterated in bilateral statements with U.S. officials. Syria has explicitly ruled out joining amid unresolved border tensions, while Lebanon’s internal political shifts have not yet produced a viable path to signature. U.S. efforts to link Saudi civilian nuclear cooperation to Accords participation in July 2026 have not altered Riyadh’s requirements. With five months remaining before 2027 and persistent regional frictions tied to Gaza and Iran, traders see limited near-term scope for additional signatories.
