I'll research this company to verify its profile.
Company overview. NinjaTrader Group, LLC is a Chicago-based financial technology and brokerage holding company founded in 2003 by Raymond Deux. It operates through affiliates including NinjaTrader, LLC (trading platform), NinjaTrader Brokerage, LLC, NinjaTrader Clearing, LLC (a CFTC-registered Futures Commission Merchant doing business as Kraken Derivatives US), and Tradovate, LLC. It was private and majority-backed by Long Ridge Equity Partners, with DRW Venture Capital and Capital Southwest also invested (2019 buyout). In March 2025, crypto exchange Kraken agreed to acquire NinjaTrader for $1.5 billion; the deal closed May 1, 2025, making NinjaTrader a Kraken subsidiary operating as a standalone platform. Kraken's press materials reported roughly 400 employees at announcement.
Products / services. NinjaTrader is a real operating company, not an NPE. Its flagship NinjaTrader platform provides futures and forex charting, market analytics, strategy backtesting, automated/manual trade execution, and trade simulation on desktop, web, and mobile. It runs a discount futures brokerage and clearing business, serves roughly two million retail traders, and supports an ecosystem of third-party add-on developers. Following the Kraken acquisition, its FCM license powers Kraken Derivatives US (CME-listed crypto futures initially).
Patent-litigation posture. The tracked record shows a defensive, one-way posture: 1 case as defendant and 2 as plaintiff, the latter being PTAB proceedings. This is consistent with an operating company targeted by a patent assertion entity rather than a serial litigant. The single district court suit was filed in the plaintiff-friendly Eastern District of Texas, Tyler Division.
Notable cases. Chart Trading Development, LLC v. NinjaTrader Group, LLC et al. (E.D. Tex., filed Dec. 3, 2015) named NinjaTrader as defendant — an NPE-style assertion over charting/trading technology. On Feb. 19, 2016, NinjaTrader appeared as a petitioner alongside Interactive Brokers LLC ("et al.") in two PTAB proceedings against Chart Trading Development patents, seeking review of the asserted claims.
