Recent diplomatic assessments, including an October 2026 Council for a Secure America analysis, rank Kuwait, Lebanon, and Syria as the leading candidates for Abraham Accords accession, yet each faces substantial procedural and political hurdles. Saudi Arabia’s normalization track has cooled further amid the 2026 Iran War and Riyadh’s continued linkage of any deal to Palestinian statehood progress. September 2026 multilateral meetings among existing signatories and Kazakhstan (which acceded in late 2025) focused on deepening cooperation rather than adding members, with public estimates for potential new entrants extending into 2027. Ongoing regional security dynamics, domestic constraints in prospective states, and the absence of finalized frameworks within the narrow remaining window support trader consensus that no additional country will formalize accession before the end of 2026.
