Ongoing regional tensions, particularly Saudi Arabia’s insistence on concrete progress toward a Palestinian state before any normalization with Israel, continue to block major expansions. U.S. diplomatic pushes under the second Trump administration, including public calls in mid-2026 for simultaneous accessions by Riyadh, Doha, and others tied to an Iran framework, have yielded only statements rather than completed agreements. Kazakhstan formalized its entry in early 2026 and Somaliland pledged following Israel’s December 2025 recognition, but subsequent activity has centered on exploratory talks with Syria, Lebanon, and additional Central Asian states without verified breakthroughs. With roughly 16 months remaining before 2027 and core political obstacles—including Israeli military operations and stalled two-state pathways—unresolved, trader consensus assigns high probability to no further signatories.
