August 14, 2026. The latest edition of The ICSID Caseload - Statistics reflects sustained and growing demand for ICSID’s services during Fiscal Year 2026 (FY2026), spanning from July 1, 2025, to June 30, 2026. During this period, ICSID administered 363 cases, the highest number of cases in a fiscal year in its history. In addition, the Centre provided services for 15 cases under non-ICSID rules, including 12 cases under the UNCITRAL Arbitration Rules.
As of June 30, 2026, ICSID had registered a total of 1,118 arbitration and conciliation cases under the ICSID Convention and Additional Facility Rules, including 60 new cases in FY2026. Among the new cases, 62% invoked ICSID jurisdiction based on a bilateral investment treaty (BIT), 24% on other international treaties, 8% on contracts between a host State and an investor, and 6% on domestic investment laws.
In FY2026, 12% of newly registered cases included disclosures of third-party funding. Under Rule 14 of the 2022 ICSID Convention Arbitration Rules and Rule 23 of the 2022 ICSID Additional Facility Arbitration Rules, parties are required to disclose any third-party funding received for the pursuit or defense of a proceeding.
As of June 30, 2026, the Centre had received one request for mediation based on a pre-existing agreement to mediate (ICSID Mediation Rule 5), and had administered that mediation. ICSID also received six requests to institute a mediation where the parties had no prior written agreement to pursue mediation (ICSID Mediation Rule 6). Consistent with the confidentiality regime applicable to its mediation proceedings, the Centre reports only aggregated data on mediations.
