Washington — Kanter Launches AI Antitrust Startup FluxCap

Jonathan Kanter, who led the Justice Department's Antitrust Division from 2021 until he stepped down in 2024, has launched an artificial-intelligence startup called FluxCap that sells legal research tools to plaintiffs building monopoly cases against dominant companies, according to a Nov. 9, 2026, report in The Verge. Kanter co-founded the company with Doha Mekki, a former acting head of the Antitrust Division, The Verge reported, and the venture marks his first major move since leaving government to keep fighting what he calls illegal monopolies, per the outlet.

What does FluxCap sell?

FluxCap is an AI-based legal research and analysis platform built to help plaintiffs "build and strengthen cases" against well-resourced corporate defendants, The Verge reported, citing Kanter. The company is launching with an initial focus on antitrust litigation, the kind of cases Kanter and Mekki pursued against technology companies at the Justice Department, and plans to expand into other legal practice areas over time, according to the outlet. Kanter described the product as a "force multiplier" intended to help antitrust watchdogs compete against the legal budgets of Big Tech and other powerful opponents, The Verge reported.

Who is building it?

FluxCap's staff includes former Justice Department attorneys and former engineers from Palantir, according to The Verge. Mekki, who served as acting head of the Antitrust Division, joins Kanter as a co-founder, the outlet reported. Both officials led the government's antitrust cases against major technology companies before departing the department in 2024, The Verge reported.

Why does Kanter call AI enforcement "existential"?

"This, to me, it's existential," Kanter told The Verge, arguing that AI tools may be "the only way that enforcement is going to work in the long term." Kanter's framing reflects a wager that private litigants and even government regulators without matching budgets need technology to offset the legal resources that large corporate defendants can deploy, according to his interview with the outlet.

How does FluxCap fit the broader AI investment climate?

FluxCap's debut lands as investors continue debating how much capital AI ventures deserve. HTT News has reported that markets kept climbing despite pressure tied to Nvidia even as a separate selloff prompted scrutiny of SoftBank's AI bet. FluxCap's emergence as a legal-tech-specific application adds another data point to that broader sorting-out of which AI products attract durable paying customers rather than speculative investment.

What to watch

• Whether FluxCap signs plaintiffs' firms or government agencies as early customers.
• Whether the startup's planned expansion beyond antitrust reaches consumer protection or labor cases.
• Whether Big Tech defendants respond by building their own AI litigation tools.
