In a statement, the committee said Nurlan Zhakupov, chairman of the management board of Samruk-Kazyna, and Yelzhas Otynshiyev, chairman of the management board of Kazakhstan Temir Zholy (KTZ), were detained on November 11 by the KNB's Anti-Corruption Service, along with several other individuals it did not name, the state news agency Qazinform reported.

The committee said investigative proceedings are under way to establish all the circumstances of the case, but it disclosed no details of the alleged conduct, citing Article 201 of Kazakhstan's Criminal Procedure Code, which restricts disclosure of information from pretrial investigations, The Times of Central Asia reported.

Two of the most powerful jobs in Kazakhstan's state economy

Samruk-Kazyna, founded in 2008, is the state's holding company for Kazakhstan's largest enterprises. Its portfolio includes the national oil and gas company KazMunayGas, uranium producer Kazatomprom, the national airline Air Astana and KTZ itself, across the energy, transport, telecommunications and infrastructure sectors. In March 2025, Zhakupov briefed President Kassym-Jomart Tokayev on an investment portfolio of 130 projects worth more than $100 billion — yaani more than 10,000 crore US dollars.

Zhakupov had headed Samruk-Kazyna since 2023. Otynshiyev became head of KTZ on July 20, 2026, after previously holding senior positions at Samruk-Kazyna overseeing strategy and asset management; the fund is the railway company's sole shareholder.

Why the railway matters far beyond Kazakhstan

KTZ manages Kazakhstan's mainline railway network and is a central operator in developing the Trans-Caspian International Transport Route, known as the Middle Corridor — the freight route that connects China with European markets through Kazakhstan, the Caspian Sea, Azerbaijan and Georgia, allowing cargo to bypass Russia. The company has also been preparing for an initial public offering (IPO) that would open it to private investors, and the detentions cast fresh uncertainty over that timetable.

The Times of Central Asia noted that, according to World Bank estimates, developing the Middle Corridor through 2040 will require at least $25 billion to modernise transport infrastructure and another $30.5 billion for logistics centres, industrial zones and related projects — and that the bank has recommended improving governance at state-owned transport companies, including more transparent tariffs and greater private-sector participation.

Prime Minister Olzhas Bektenov had criticised Samruk-Kazyna's management earlier in November over missed deadlines for investment projects, Qazinform reported. The KNB has not suggested that those delays — or KTZ's delayed Stadler passenger-train contract, whose first new cars entered service between Astana and Almaty on November 11 — are connected to the investigation.

The KNB said its anti-corruption work is continuing in line with President Tokayev's instructions and the government's 'Law and Order' principle. As of publication, Samruk-Kazyna had issued no statement on its chief executive's position and no successor or acting head had been announced. What happens next — formal charges, court hearings on custody, and any leadership changes at the fund and the railway — will decide how far the case reaches into the companies that move Kazakhstan's oil, uranium and China–Europe freight.
