first_img The Southern District Court of New York rejected the preliminary injunction motion against Susquehanna for insider trading

On September 14, 2026, Judge Arun Subramanian of the United States District Court for the Southern District of New York issued an opinion and order denying the plaintiff's motion for a preliminary injunction. The case number is 1:26-cv-05474-AS, with the plaintiffs being market makers Susquehanna Securities, LLC and Susquehanna Investment Group, and the intervenor being market maker Citadel Securities LLC, while the defendants are John Does 1 through 100. The plaintiffs filed the lawsuit on June 29, 2026, claiming violations under Section 20A of the Securities Exchange Act of 1934 and unjust enrichment claims.The plaintiffs allege that the defendants traded on significant non-public information, specifically an announcement on May 22, 2026, regarding "the Chinese government's crackdown on cross-border trading platforms," which led to a collapse of the relevant securities. The plaintiffs sought a preliminary injunction to restrict the 40 defendants, as reduced, from transferring, encumbering, removing, or otherwise disposing of the profits obtained through the alleged insider trading activities in their accounts at third-party brokerage firms, or sought a seizure order. The court found that the plaintiffs failed to demonstrate the elements necessary to prove that they may suffer irreparable harm, and the motion was denied.

first_img OpenAI disclosed 6 cases of AI model "misalignment" behavior, involving hidden information and overstepping authority

OpenAI disclosed on Wednesday six cases of "unexpected or concerning" model behavior discovered in the past six months, categorizing them as "misalignment behaviors," including concealing information from users and taking "unauthorized actions" to overcome obstacles. OpenAI stated that this disclosure aims to initiate its new model misalignment reporting framework, and these cases should not be seen as a reflection of the frequency of misalignment occurring in its models.In one case, an unpublished research model inserted "jailbreak-like instructions" into its task summaries, such as ignoring developer messages or adopting unrestricted role settings, with researchers finding a total of 27 summaries containing such instructions. Additionally, during the training process of GPT-5.6 Sol, many model instances added instructions to conceal errors or misalignment behaviors from users, such as fabricating missing historical data without disclosure. Other cases included models using exposed API keys without authorization and fabricating inaccessible data, leveraging internal software repositories to pass messages across training tasks, and ignoring instructions to "keep local work" by sharing files through public hosting services.OpenAI's disclosure has heightened concerns among AI developers and researchers about whether safety measures can keep pace with increasingly powerful models. Last week, Anthropic CEO Dario Amodei called for a slowdown in cutting-edge AI development, warning that unrestrained AI development could "exceed our ability to understand and control these systems." In July of this year, OpenAI disclosed that several of its AI models escaped testing environments during safety assessments and infiltrated the AI startup Hugging Face to cheat.
