Citadel Securities drops US lawsuit against Portofino Technologies, pivots to £6M UK judgment
The market-making giant abandons a nearly three-year trade secrets battle to chase actual money through British bankruptcy courts instead
Citadel Securities has walked away from its US trade secrets lawsuit against crypto market maker Portofino Technologies, ending a legal saga that stretched nearly three years without ever producing a ruling on the merits. The voluntary dismissal, filed on July 8, 2026, came after both sides agreed to drop the case, with each party covering its own costs.
Citadel is now channeling its legal firepower into enforcing a £5.98 million (roughly $7.9 million) arbitration award against Portofino co-founder Leonard Lancia through bankruptcy proceedings in the UK.
From trade secrets to balance sheets
The original US lawsuit, filed in New York in 2023, accused Portofino’s founders of walking out the door with proprietary trading strategies and other intellectual property.
Portofino was founded in 2021 by Leonard Lancia and Alex Casimo, both former Citadel executives. The firm quickly established itself as a high-frequency crypto market maker, raising over $50 million in funding in 2022 and securing a UK digital asset service provider license.
The US case survived several motions to dismiss. The English High Court recognized the £5.98 million arbitration award back in February 2026. A statutory demand followed in April 2026. When Lancia didn’t pay up, the situation escalated. Lancia now sits under a worldwide freezing order, designed to prevent someone from moving money around while creditors come knocking.
Why the strategy shift matters
Bankruptcy proceedings present narrower legal questions than trade secrets litigation. Citadel has a recognized judgment, the debtor hasn’t paid, and the path to actually recovering money is clearer than in trade secrets litigation.
Lancia holds a stake in Portofino Technologies, and a bankruptcy proceeding could potentially force the liquidation of that stake.
What this means for investors and the crypto market
Portofino has continued operating throughout the entire litigation as a high-frequency crypto market maker without material disruption to its business.
If a co-founder’s stake in the company gets caught up in insolvency proceedings, it creates questions about ownership structure, governance, and potential forced sales.
The $50 million that investors put into Portofino in 2022 came with the implicit bet that Lancia and Casimo’s expertise, built at Citadel, could be successfully transplanted into crypto markets.
The freezing order on Lancia’s worldwide assets means a London court has effectively immobilized a founder’s global asset base. What traders should watch now is whether the bankruptcy petition succeeds and, if it does, what happens to Lancia’s Portofino stake.
