Citadel Securities lawsuit proceeds against former employees’ crypto startup

As a seasoned researcher with years of experience in following high-stakes legal battles within the financial sector, I find myself intrigued by this ongoing saga between Citadel Securities and Portofino. The latest ruling by the U.S District Court in Manhattan seems to be a mixed bag for both parties.


In simpler terms, a court in New York City has decided that a legal dispute between Citadel Securities and a cryptocurrency trading startup called Portofino, where Citadel claims Portofino stole their confidential information, can largely move forward with the case.

Based on a court document filed on October 30th, the Manhattan District Court has decided to move forward with Citadel’s legal action against cryptocurrency trading startup Portofino. This lawsuit stems from the allegation that two ex-employees of Citadel Securities, who are now associated with Portofino, are accused of misappropriating trade secrets to establish their startup.

The judge denied in part Portofino’s motion to dismiss the case, but he also did the same to Citadel Securities’ claims that Portofino breached the employment contracts of three Citadel Securities workers it tried to recruit.

Earlier, Citadel Securities claimed that Portofino breached the employment contract when they hired their systematic options trader, Taym Moustapha. Furthermore, Citadel asserted that they had to raise the salary significantly for an unnamed employee as a countermeasure to match the offer made by Portofino.

The judge dismissed Citadel Securities claims regarding Moustapha and two unidentified employees, but gave the firm leave to file an amended complaint to fill in the gaps pointed out by the court during the conference. The court gave Citadel Securities a maximum of 30 days to refile its complaint.

In addition, a different complaint lodged by the company regarding another staff member was granted permission to move forward.

On October 31st, the court agreed to dismiss Citadel’s case regarding the seed investor at Portofino’s request.

According to U.S. District Judge Gregory Woods’ court document, the Plaintiffs failed to prove that the Defendant foresaw or could reasonably have anticipated that his investment in Portofino would lead to repercussions in New York.

Woods elaborated that the court had no authority to intervene in the case involving Jean Canzoneri, a French seed investor. Additionally, the judge pointed out that any claims against Canzoneri regarding his investment were prior to Portofino’s establishment and any accusations of misappropriating trade secrets.

Canzoneri argued the case against him should be dismissed because Citadel Securities could not accuse him of aiding and abetting trade-secret theft by investing in Portofino.

According to Canzoneri, anyone who invests in a startup where the founders have previous work experience understands that these founders might be taking confidential information from their former employers.

Back in May 2023, Citadel Securities took legal action against ex-employees Leonard Lancia and Alex Casimo. The accusation was that they had illegally obtained confidential information (trade secrets) from their previous job at Citadel, which they then used to establish and operate a crypto-focused market-making company called Portofino.

In reaction to the lawsuit, Portofino submitted a request to throw out the case in the same year, arguing that the lawsuit was intended to scare the two ex-employees and discourage current employees from taking similar actions. However, Portofino has continued to maintain its innocence regarding Citadel Securities’ accusations of trade-secrets misappropriation.

According to Citadel Securities, they claim to possess confidential information such as ‘research,’ ‘trading strategies,’ ‘simulations,’ and ‘business plans and strategies.’ However, Portofino argues that these broad terms encompass the entirety of any High-Frequency Trading (HFT) business, as stated in a Bloomberg report.
