Ex-DOJ Chief Uses AI to Fight Monopolies

Jonathan Kanter, formerly the head of the Justice Department's Antitrust Division, has co-founded FluxCap, a private sector startup employing AI to assist in dismantling illegal monopolies. Launched in 2024, FluxCap offers an AI-based legal research and analysis tool aimed at bolstering cases brought by plaintiffs against well-resourced companies.

Kanter describes FluxCap as a 'force multiplier,' intended to enable enforcement agencies and private plaintiffs to compete more effectively against large corporations. The platform leverages proprietary technology and large language models to identify case-critical facts and legal frameworks, and can sift through discovery materials for anticompetitive signals.

FluxCap's development was informed by Kanter's experience at the DOJ, where he recognized the significant resource imbalance between government enforcers and multibillion-dollar corporations. While the Antitrust Division received $245 million for fiscal year 2026, this pales in comparison to the financial and legal might of major tech companies.

The tool aims to provide the equivalent manpower of over 20 people working around the clock, giving smaller teams a significant advantage. Kanter emphasizes that while technology alone cannot fully equalize the playing field, FluxCap is designed to be 'the great equalizer,' allowing teams to challenge powerful opponents regardless of their size or financial depth.
