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.

Two Robinhood employees have been sued for insider trading for pre-positioning through Hyperliquid before the coin listing

On September 15, local time, the U.S. Attorney's Office for the Southern District of New York (SDNY) announced that two Robinhood engineers, Hefu Chai and Huaisong Xiang (also known as Jerry Xiang), have been charged with commodity fraud and wire fraud for allegedly trading Hyperliquid perpetual contracts using non-public information from the company.SDNY stated that during their tenure at Robinhood, the two had access to confidential information regarding the launch of new tokens and their launch timelines from Robinhood Crypto. Between 2025 and 2026, they are accused of repeatedly purchasing Hyperliquid perpetual contracts for the corresponding tokens before the company publicly announced the launch of those tokens, profiting after the news broke, with each allegedly earning over $50,000. Prosecutors emphasized that although perpetual contracts are traded on blockchain derivative platforms, they still fall under accountable financial instruments.U.S. Attorney Jamie McDonald stated that corporate insiders cannot evade relevant securities and commodities market laws by trading perpetual contracts, tokenized securities, or other similar financial products. The 36-year-old Chai will appear in court in the Northern District of California, while the 30-year-old Xiang will appear in federal court in the Southern District of New York. The maximum penalty for violations of the Commodity Exchange Act they face is 10 years in prison, and for wire fraud, up to 20 years in prison. SDNY emphasized that the contents of the indictment at this stage are merely allegations, and both defendants are presumed innocent until proven guilty in court.

The U.S. CFTC has added 3 new insider trading investigations into Polymarket: involving Biden's pardons, the Iran war, and Google

The U.S. Commodity Futures Trading Commission (CFTC) has previously secretly approved at least three insider trading investigations related to Polymarket trading, involving contracts related to Biden's pardons, the Iran war, and Google-related events. The relevant investigation documents were obtained by WIRED through the Freedom of Information Act.Among them, CFTC Chairman Michael Selig approved an investigation into contracts related to Biden's pardons in May, after a trader had profited over $300,000 in the relevant market; in the same month, the CFTC also approved an investigation into Iran war contracts, after a group of suspicious accounts was reported to have profited $2.4 million with a win rate of about 98%. In July, the CFTC further initiated an investigation into Google-related Polymarket contracts, focusing on individuals who may have traded using non-public information regarding Google's 2025 search rankings. The Southern District Attorney's Office in New York is also conducting a parallel investigation.It is currently unclear whether the aforementioned accounts are connected to previously investigated individuals. Polymarket stated that the company would refer the relevant matters to law enforcement and cooperate with the investigation. As the prediction market rapidly expands, U.S. regulators are clearly intensifying their scrutiny of insider trading and market manipulation.

first_img Insiders: Hyperliquid core contributors have publicly sought feedback on the HIP-4 template

According to a post by @0xMaxs, Hyperliquid core contributor Xulian is publicly soliciting feedback on the latest testnet template for HIP-4. The template can be accessed via on-chain queries or the testnet API, with each template family identified by an incrementing integer suffix for the latest version. After collecting feedback, validators will review and vote on-chain, and only approved templates will be written to the mainnet for deployers to use; all template instantiations still depend on HIP-4 being enabled on the mainnet.It is reported that the testnet currently has 16 template records (including old versions), with approximately 12 latest templates based on the highest version of each family, covering 7 types of market structures. Candidate types include expiration prices (settled using specified period TWAP), price-triggered markets, range earnings, as well as central bank decisions, sports two-way options, and sports win/draw/loss, etc. The mainnet outcomeTemplates and deployer list are currently still empty, and permissionless templates have not yet been officially opened.HIP-4 is Hyperliquid's permissionless deployment standard for outcome/prediction markets, with the complete process being: community feedback, validator review, on-chain voting, template writing to the mainnet, and market creation by deployers once the switch is enabled.
