Naftogaz of Ukraine and six group companies brought arbitration against Russia under the Ukraine–Russia bilateral investment treaty (BIT) over the 2014 seizure of their Crimean assets. An April 2023 final award ordered Russia to pay about $5B, and Naftogaz is enforcing it against Russian state assets in about 10 jurisdictions. On October 28, 2026, a Norwegian court rejected a challenge to the arrest of a Russian vessel in Svalbard.
Latest development Oct 28, 2026
On October 28, 2026, the District Court of Nord-Troms and Senja rejected a challenge by Russian state trust Arktikugol to lift the arrest of the vessel Professor Molchanov in Svalbard. The court found that Arktikugol, which does not own the vessel, lacked standing, and ordered it to reimburse Naftogaz’s legal costs. Naftogaz is seeking a forced sale of the vessel.
Why it matters
Naftogaz’s campaign tests how an investor can turn a treaty award against Russia into recoveries through exequatur, attachment, and auction of Russian state assets, jurisdiction by jurisdiction. The outcome matters to other holders of Ukraine-related awards against Russia and to states holding frozen Russian assets.
Background
After annexing Crimea in 2014, Russia seized the Naftogaz group’s assets on the peninsula, including Chornomornaftogaz’s offshore fields, rigs, and pipelines. In October 2016, NJSC Naftogaz of Ukraine and six group companies began arbitration under the 1998 Ukraine–Russia bilateral investment treaty (BIT). The case (PCA Case No. 2017-16) is seated in The Hague before Ian Binnie, Charles Poncet, and Maja Stanivuković. In a partial award of February 22, 2019, the tribunal upheld jurisdiction and found Russia liable for expropriation.
The Hague Court of Appeal rejected Russia’s challenge to the partial award in July 2022. The final award of April 12, 2023, ordered Russia to pay about $4.22B plus interest running from March 2014 and costs, roughly $5B. The English High Court recognized the award in December 2023. In December 2024, the Dutch Supreme Court dismissed Russia’s cassation appeal against the partial award.
Russia refuses to pay, and Naftogaz is enforcing the award against Russian state assets in about 10 jurisdictions. Covington & Burling filed a petition to confirm and enforce the award in the U.S. District Court for the District of Columbia. The Paris Judicial Court granted exequatur on April 17, 2025. Naftogaz then registered charges over Russian state properties in France worth more than €120M. In August 2025, the Vienna Inner City District Court authorized the encumbrance and auction of more than 20 Russian-owned properties in Austria, also worth more than €120M. Finnish authorities have frozen and progressively realized Russian assets since 2024, and more than €40M had been seized by June 2026.
On July 17, 2026, the D.C. court refused to reimpose a stay of the petition. It found speculative Russia’s argument that a pending Dutch appeal risked inconsistent results. On September 2, 2026, Norwegian authorities seized the Russian state-owned vessel Professor Molchanov in Svalbard under an August 31 order of the District Court of Nord-Troms and Senja. Russia has said it will appeal, and Naftogaz is seeking a forced sale of the vessel. On October 21, 2026, the Oslo District Court authorized Naftogaz to seize five Russian-owned properties in Oslo’s Frogner district. On October 28, 2026, the Nord-Troms and Senja court held that Russian state trust Arktikugol lacked standing to challenge the arrest and ordered it to pay Naftogaz’s legal costs. Also in October 2026, press reports described a Dutch setback that could reduce the award, and the D.C. court declined to dismiss the petition.

Experimental AI forecast
How it is madeWill the U.S. District Court for the District of Columbia confirm Naftogaz’s $5 billion Crimea award against Russia by June 30, 2028?
- Court confirms Naftogaz award46%
- Still pending on June 30, 202842%
- Court dismisses or denies petition12%
- Resolves by
- Jun 30, 2028in 20 months
- Record confidence
- Medium
Confirmation of the award by the D.C. court by June 30, 2028, is the most likely outcome, at 46%. The court has denied Russia’s bid to stay and its motion to dismiss, which removes the main threshold barriers. The leading alternative is delay from a Russian appeal on immunity or a Dutch damages ruling.
How it resolves. Resolves “Court confirms Naftogaz award” if, by June 30, 2028, the D.C. district court enters an order or judgment confirming or recognizing the April 12, 2023, award in whole or in part, including at a reduced amount. Resolves “Court dismisses or denies petition” if the court dismisses the petition or denies confirmation entirely by that date. Resolves “Still pending” if neither has occurred, including where the case is stayed or awaiting an appeal.
Reasoning
Starting point. U.S. federal petitions to confirm investment treaty awards against foreign sovereigns under the FSIA arbitration exception: Most such petitions that survive a motion to dismiss end in confirmation (roughly 80% to 90%), but sovereign appeals often add one to three years
U.S. courts confirm most treaty awards against sovereigns once jurisdiction under the FSIA arbitration exception is upheld, often at rates above 80%. Here the court refused to reimpose a stay in July 2026 and declined to dismiss the petition in October 2026, so the case is moving toward the merits of confirmation. Timing is the main risk, because a denial of sovereign immunity is often immediately appealable to the D.C. Circuit, and that appeal could suspend district court proceedings well into 2028. A reported Dutch ruling that may set aside a significant part of the damages could also prompt renewed stay requests or a partial confirmation, though partial confirmation counts as confirmation here. Outright dismissal or denial looks unlikely after the October ruling, given the upheld partial award and recognitions in England and France. The previous forecast asked the same question on the same date, and nothing new in the record justifies changing its numbers.
Court denied Russia’s motion to dismiss in October 2026 · Likely Russian collateral appeal on sovereign immunity could delay judgment · Reported Dutch ruling may reduce damages and invite stay requests · Court already rejected stay as speculative in July 2026 · Dutch courts upheld liability, and England and France recognized award
