**No new Arab or Muslim-majority state has advanced toward formal accession since Kazakhstan joined in November 2025 and Somaliland pledged in December 2025.** Saudi Arabia, the leading candidate, continues to condition normalization on concrete progress toward Palestinian statehood—a precondition the kingdom has reiterated publicly despite U.S. diplomatic pressure and linkage of a civil nuclear agreement to Abraham Accords accession. Syria has explicitly declined, while potential candidates such as Qatar, Kuwait, Oman, and Lebanon face domestic, regional, and security constraints with no active negotiations nearing completion. With roughly four months remaining before 2027, the absence of verifiable diplomatic breakthroughs or scheduled signing timelines underpins trader expectations reflected in the current odds.
