ICSID pending cases are investor-State arbitrations and conciliations that ICSID has registered but not yet ended by an award, a settlement, or a withdrawal. As of September 16, 2026, ICSID’s online pending list shows about 300 matters. Most are ICSID Convention cases, and Peru, Mexico, and Colombia face the largest pending dockets.
This guide sets out what “pending” means under the ICSID Convention and the 2022 Arbitration Rules. It also shows where to find every pending matter, sums up the Fiscal Year 2026 caseload figures, and shows what the docket signals for investors and States. ICSID, the International Centre for Settlement of Investment Disputes, is the World Bank Group body that handles most investor-State dispute settlement (ISDS) claims. Investors bring those claims under bilateral investment treaties (BITs), the Energy Charter Treaty, investment laws, and contracts. Its docket is therefore a useful gauge of foreign direct investment risk, above all in Latin America.
What Counts as a Pending Case at ICSID?
To begin with, a case becomes pending on the day ICSID registers it. Under Article 36(3) of the ICSID Convention, the Secretary-General registers a request for arbitration unless the dispute is manifestly outside the Centre’s jurisdiction. According to ICSID, that step takes about three weeks on average once the Centre has the complete request and the lodging fee.
The case then stays pending through every stage. First, the parties form the Tribunal. Next, the Tribunal holds a first session and sets the dates. Then come the written briefs, document exchange, and the hearing. Finally, the Tribunal confers and issues the award. Under Article 53, that award binds the parties and is not subject to any appeal.
Remedies after the award
In addition, steps after the award also appear as pending matters. A party may seek a supplementary decision or rectification within 45 days (Article 49(2)). It may request interpretation at any time (Article 50). It may apply for revision within 90 days of finding a new fact, and no later than three years after the award (Article 51). Finally, it may apply for annulment within 120 days on one of five grounds (Article 52). As a result, a dispute can remain pending for years after the Tribunal has ruled. In other words, the list of ICSID pending cases covers matters at every one of these stages.
How to Track ICSID Pending Cases
In fact, ICSID shares more about its docket than most other bodies. In short, these six steps cover nearly all of what a company or its counsel needs.
Six sources to check
Search the case database. The Centre’s online case search lets you filter by status, Respondent State, sector, the rules that apply, and the treaty or contract invoked.
Open the Pending Cases list. ICSID keeps a running list of pending matters in date order, next to a second list of closed cases.
Read the case details. Under Administrative and Financial Regulations 25 and 26, ICSID keeps registers for every case. Each case page shows how the Tribunal was formed, who sits on it, and every step taken to date.
Download the public filings. Under Arbitration Rule 62, ICSID posts awards with the parties’ consent, and consent is deemed given if no party objects within 60 days. If a party objects, ICSID posts excerpts. Orders and rulings are posted under Rule 63, and a party may post its own filings under Rule 64.
Cross-check other sources. UNCTAD’s Investment Dispute Settlement Navigator, italaw, and Jus Mundi index the same cases with treaty texts and notes.
Read the half-year figures. The ICSID Caseload – Statistics comes out twice a year and covers every case logged since 1972.
The ICSID Caseload in 2026: Key Numbers
Meanwhile, ICSID issued its Fiscal Year 2026 statistics on August 14, 2026. Specifically, the report covers July 1, 2025 to June 30, 2026. The main figures appear below.
| Indicator | FY2026 figure (ICSID) |
|---|---|
| Cases logged since 1972 | 1,118 as of June 30, 2026 |
| New cases logged in FY2026 | 60 (57 Convention arbitrations, 3 Additional Facility arbitrations) |
| Cases handled in FY2026 | 363 ICSID cases, a record, plus 15 non-ICSID cases |
| Basis of consent (new cases) | BITs 62%; Energy Charter Treaty 10%; contracts 8%; investment laws 6% |
| Largest sectors (new cases) | Oil and gas 25%; mining 18%; electric power and other energy 10%; finance 10% |
| Respondent regions (new cases) | South America 22%; Eastern Europe and Central Asia 20%; Sub-Saharan Africa 20%; Western Europe 13% |
| Third-party funding disclosed | 12% of new cases (Rule 14) |
| Membership | 158 Contracting States and 8 signatory States |
Outcomes and annulment results
The outcome data matter as much as the volume. Of the cases closed in FY2026, 63% were decided by a Tribunal and 37% were settled or dropped. Among decided cases, 40% ended with an award that threw out every claim. Another 37% upheld claims in part or in full, 18% declined jurisdiction, and 5% were thrown out for manifest lack of legal merit. Moreover, 70% of the cases decided in FY2026 produced no damages for the investor. Anyone tracking the ICSID caseload should read these figures next to the raw case counts.
Likewise, annulment remains rare. Through the end of FY2026, Tribunals had issued 543 awards under the Convention. Ad hoc committees turned down 124 bids to annul awards and annulled 28 awards, 20 in part and 8 in full. Another 51 such cases were dropped.
Which States Face the Most Pending ICSID Cases?
We reviewed ICSID’s pending list on September 16, 2026. It contained 300 matters: 272 ICSID Convention cases, 20 Additional Facility cases, two conciliations, and six cases run under the UNCITRAL Rules or ad hoc arrangements. Cases under the ICSID Additional Facility Rules, which are available when the host State or the investor’s home State is not a Contracting State, appear in the same lists. The Respondent States with the most pending cases were as follows.
| Respondent State | Pending cases (September 16, 2026) |
|---|---|
| Peru | 21 |
| Mexico | 20 |
| Colombia | 19 |
| Honduras | 13 |
| Panama | 10 |
| Spain | 10 |
| Ukraine | 9 |
| Romania | 9 |
| Argentina | 8 |
| Venezuela | 7 |
Meanwhile, by sector, oil, gas, and mining disputes accounted for 105 of the 300 pending matters. Electric Power and Other Energy followed with 43, then Construction with 36, Transport with 26, and Finance with 25. In other words, natural-resource and project deals still drive the ICSID docket.
How Long Does a Case Stay Pending?
The 2022 ICSID Arbitration Rules set firm timeframes for the award. In an ordinary case, the Tribunal must render its award within 240 days after the last submission (Rule 58(1)). However, shorter deadlines apply to special procedures. A Tribunal must decide an objection that a claim is manifestly without legal merit within 60 days (Rule 41(2)(e)). It must render an award declining jurisdiction in a split (bifurcated) case within 180 days (Rule 44(3)). Tribunals must use best efforts to meet these limits under Rule 12(1), and they must explain any delay.
Even so, a dispute often spans several years from the day it is logged to its final outcome, above all when a party seeks annulment. That is why so many ICSID pending cases are several years old. Parties who want speed can agree to expedited arbitration under Chapter XII of the 2022 Rules, which begins at Rule 75.
A six-year example from Korea
For example, a recent decision shows how long “pending” can last. In *Fengzhen Min v. Republic of Korea* (ICSID Case No. ARB/20/26), a Chinese investor filed a claim under the China–Korea BIT in 2020. The Tribunal decided Korea’s Rule 41(5) objection on June 18, 2021, and dismissed all claims in an award dated May 30, 2024. Korea’s Ministry of Justice then said that an ad hoc committee turned down the investor’s annulment request on September 13, 2026, more than six years after the case began. The Tribunal had found that an investment made in violation of Korean law fell outside the treaty’s protection, and the committee left that finding intact.
What Pending Cases Signal for Investors and States
Firstly, for an investor, a State’s pending docket is a practical risk signal. A cluster of cases in one sector often points to a change in the rules, such as a tariff reform or a permit crackdown, that could affect similar projects. In addition, it shows how the State litigates: whether it settles early, raises objections under Rule 41, or requests security for costs under Rule 53.
For claimants and States
Secondly, for a claimant, the numbers set expectations. Roughly two out of three closed ICSID cases are decided by a Tribunal, and most decided cases end without damages. Therefore, treaty cover, proof that the investment followed local law, and a sound damages model matter more than the size of the claim. Third-party funders read the same data, and Rule 14 requires every funded party to name its funder. As a result, checking the pending ICSID cases against a State before filing is basic due diligence.
Finally, for a State, a growing pending list carries budget and reputation risks. Early case review, a single defense team, and a clear plan to settle can shorten the docket. Korea’s team-based defense in the Min case shows how that can work.
Our firm advises investors and businesses on treaty planning, investment disputes with host States, and plans after the award, such as how annulment cases work and how to enforce an award once the case leaves the pending list.
Frequently Asked Questions
As of September 16, 2026, ICSID’s online list showed about 300 pending matters, and that figure includes steps after the award. In addition, ICSID said that it handled 363 cases during Fiscal Year 2026, the highest number in its history. The exact figure changes weekly as new cases are logged and awards come out.
First, open the ICSID case database, filter by the Respondent State, and set the status to pending. Each result links to a case page with the Tribunal’s composition, the instrument invoked, and a dated list of case steps. UNCTAD’s Investment Dispute Settlement Navigator offers a useful cross-check.
Often, yes. ICSID publishes orders and rulings under Rule 63, with agreed redactions, and it posts awards under Rule 62 unless a party objects within 60 days. Hearings are open to observers under Rule 65 unless either party objects.
Yes. For instance, the parties may jointly ask to drop the case under Rule 55, and one party may ask under Rule 56. A settlement can also be recorded in an award under Rule 55(2)(a). In FY2026, 37% of closed ICSID cases were settled or dropped.
Conclusion
ICSID pending cases are more than a list. In short, they show where investment disputes cluster, how States respond, and how long the road from registration to a final, binding award can be. The Centre’s case search, the figures it posts twice a year, and the publication rules in the 2022 Arbitration Rules give investors and States the tools to follow that road closely. In the long run, reading the docket well is the first step in managing treaty risk.
