Jane Street Group and Millennium Management have reached a settlement in a high-profile lawsuit concerning the alleged misappropriation of a proprietary India options trading strategy, bringing an end to a legal battle that captivated Wall Street.

The settlement, filed Thursday in Manhattan federal court, dismisses Jane Street’s lawsuit against Millennium and two former employees, Doug Schadewald and Daniel Spottiswood. These traders transitioned from Jane Street to Izzy Englander’s Millennium Management earlier this year. The terms of the settlement remain undisclosed.
A Billion-Dollar Trading Secret at Stake
This resolution concludes a case that pitted two financial giants against each other, raising critical questions about the protection of trading strategies as trade secrets and highlighting the growing interest in the Indian securities market.
Jane Street initiated the lawsuit in April, accusing Schadewald and Spottiswood of taking an “immensely valuable” trading strategy focused on India options. Court proceedings later revealed that this strategy generated a staggering $1 billion in profit for Jane Street in 2023. Both a Jane Street spokesperson and a lawyer representing the two traders confirmed the case was “resolved on mutually agreeable terms.” Millennium declined to comment.
Conflicting Perspectives on a Complex Strategy
While many details of the case remain redacted, the core issue revolved around whether Jane Street’s strategy qualified as a protectable trade secret. Schadewald and Spottiswood contended that their success stemmed from personal expertise and experience in the Indian options market, not from secret algorithms or automated signals. They acknowledged building the Indian options business at Jane Street but denied utilizing any confidential information.
A Landmark Case for Quantitative Trading Disputes
This case stands out amidst the more common trade-secret lawsuits on Wall Street, which often involve client lists or business plans. The Jane Street-Millennium dispute represents a novel legal challenge focused on the intellectual property of quantitative and automated trading activities.
Recent similar cases include Citadel Securities suing former employees for allegedly taking confidential strategies to a crypto startup and BTIG LLC accusing StoneX Group Inc. of stealing code for automated trading technology. According to legal experts, the law’s definition of trade secrets, encompassing formulas, methods, and processes, is broad enough to cover trading strategies, provided they possess “independent economic value from not being known” and are subject to reasonable protection efforts.
From Skepticism to Settlement
Initially, US District Judge Paul Engelmayer expressed skepticism regarding Jane Street’s claims. He ordered a more detailed disclosure of the strategy. However, he later dismissed counterclaims by Millennium and the traders alleging bad faith on Jane Street’s part. Before the settlement, Jane Street introduced evidence of Schadewald criticizing Millennium’s trading strategies as “dumb” prior to joining the firm, contradicting the defense’s argument that the strategies were “textbook.”
Millennium countered by arguing that Jane Street suffered no economic harm due to its continued success in India trading after the traders’ departure. They also unsuccessfully attempted to compel Jane Street to disclose executive compensation.
India’s Options Market and Regulatory Scrutiny
The lawsuit also brought attention to the explosive growth of India’s options market and the increasing presence of Wall Street firms like Jane Street, Millennium, Citadel Securities, and Jump Trading. Jane Street’s reported billion-dollar profits in India raised concerns amidst heavy losses suffered by retail investors, leading to new regulatory measures aimed at protecting them.
Conclusion: A Quiet Resolution to a High-Stakes Dispute
The settlement concludes a contentious chapter for both firms. It underscores the challenges of protecting intellectual property in the increasingly complex world of quantitative finance. The case leaves unanswered questions about the precise nature of the disputed strategy and the broader implications for the evolving landscape of trading and trade secrets. The undisclosed settlement terms prevent further public scrutiny of the specific details of the dispute. This case serves as a significant precedent for future disputes involving proprietary trading strategies in the financial industry.
