Kaya was remanded in custody by an Istanbul court on Friday, November 6, 2026, over allegations of violating the Capital Markets Law and membership of an organisation established for criminal activities, according to state news agency Anadolu.

She served as Turkey’s Family and Social Affairs Minister between 2016 and 2018 and was previously a deputy chair of President Recep Tayyip Erdoğan’s ruling Justice and Development Party (AKP).

The investigation centres on suspicious share transactions involving several investment funds. Prosecutors are examining allegations that Kaya had access to unpublished information capable of influencing share prices and investment decisions.

According to reports, Kaya purchased shares in shipbuilding company Özata Denizcilik in April 2026 and sold them on September 16, a day before regulators ordered the liquidation of 131 investment funds.

The main opposition party had earlier alleged that Kaya and her husband made approximately 2.17 billion Turkish lira, equivalent to about $43 million, after investing around 163 million lira in one of the funds.

The couple have denied wrongdoing. However, reports indicate that some of the profits were transferred to an account designated by banking regulators.

Kaya resigned from her position as AKP deputy chair in September after the allegations emerged. She later left the ruling party.

Her husband, İlyas Kaya, was also questioned as part of the investigation but was released under judicial supervision, with restrictions including regular reporting to authorities and a travel ban. Former Capital Markets Board chairman İbrahim Ömer Gönül was also released under judicial control.

The wider investigation has expanded significantly, with more than 430 people reportedly under investigation for suspected market manipulation and insider trading. Justice Minister Akin Gürlek said 112 people had been detained pending trial in connection with the scandal.

The case has raised concerns about transparency and oversight in Turkey’s financial markets, particularly after the suspected manipulation affected hundreds of thousands of investors.

Authorities are continuing their investigation, while the allegations against Kaya remain subject to legal proceedings.
