Summary
Kazakhstan's national security authorities have confirmed the detention of the then heads of the country's sovereign wealth fund and national railway company on suspicion of a corruption-related offence. According to the National Security Committee, Nurlan Zhakupov, then chairman of Samruk-Kazyna's management board, and Yelzhas Otynshiyev, then chairman of the management board of Kazakhstan Temir Zholy (KTZ), were detained on 11 November alongside other individuals. The committee confirmed the detentions on 12 November and said its anti-corruption service is conducting investigative work to establish the circumstances.
The committee did not specify the alleged conduct, identify the other individuals, or explain what role each detainee was suspected of playing. It also did not say whether the suspicions were connected to either organisation's activities. Citing a provision of the criminal procedure code that restricts disclosure of pre-trial investigation information, the committee has not announced formal charges. A detention on suspicion is not a finding of guilt.
Samruk-Kazyna manages major Kazakh state assets across oil and gas, energy, transport and telecommunications, including KazMunayGas and uranium producer Kazatomprom, and owns all of KTZ. KTZ operates the country's main rail network, carrying passengers and freight domestically and providing cross-border and transit services, including on the Trans-Caspian route linking Kazakhstan with Azerbaijan and Georgia. Otynshiyev became KTZ's chairman on 20 July 2026, having previously held a senior strategy and asset management position at the fund. KTZ reported transit traffic of 33 million tonnes in 2025, up from 27.5 million tonnes in 2024, and carried 13.269 million rail passengers in 2025. The source notes these figures do not establish any link to the investigation.
In a statement dated 12 November, Samruk-Kazyna said it and its group companies continue to operate as usual, and that commitments to investors, creditors, international financial institutions and business partners remain in force. It said investment projects and strategic programmes continue in line with approved plans, but gave no details of the investigation.
Before the detentions, Samruk-Kazyna and KTZ had been preparing a proposed IPO of railway company securities, with a stated objective in May of listing in 2026 on exchanges in London, Hong Kong and Kazakhstan. The proposal involved issuing new equity rather than selling existing shares, with proceeds retained by KTZ for debt repayment and investment in infrastructure and rolling stock. Market conditions, company readiness and investor interest could affect timing and structure. The security committee did not say the investigation concerned the offering, and the fund's 12 November statement did not announce any decision on the share sale.
