Denny Hamlin is suing NASCAR as part of an antitrust lawsuit centered on how NASCAR’s business model, especially its charter system and control over the sport, allegedly harms teams like his 23XI Racing organization.

Core reason: antitrust fight

Hamlin, together with Michael Jordan and Front Row Motorsports, is part of a lawsuit claiming NASCAR operates an illegal monopoly over top-level stock- car racing in the U.S.

The suit argues that NASCAR uses its control of race sanctioning, tracks, and key suppliers to limit competition and keep teams financially dependent and weak.

The charter system issue

A major focus is NASCAR’s charter system, which gives 36 teams guaranteed starting spots and revenue but on NASCAR’s terms.

Hamlin’s side claims the new long-term charter agreement locks teams into fixed payments, not a fair share of future media money, making it nearly impossible for teams to become sustainably profitable.

Why Hamlin calls it a “death certificate”

In court, Hamlin testified that 23XI has to raise tens of millions in sponsorship just to make a small profit and that agreeing to NASCAR’s proposed charter deal would put his team out of business within about a decade.

He has described the new charter terms as his team’s “death certificate,” saying suing NASCAR was the only realistic way to force change in the system.

What the lawsuit is asking for

The plaintiffs are seeking large financial damages—reports mention figures in the hundreds of millions—as well as structural changes to how NASCAR shares revenue and controls the sport.

They also argue NASCAR’s ownership of many Cup Series tracks and its mandate to use certain approved suppliers for the Next Gen car further concentrate power and hurt open competition.

Why this is a big trending topic

Fans and media are focused on this case because it could reshape how NASCAR teams get paid and how much power the sanctioning body keeps over the business side of racing.

For Hamlin, the lawsuit is both a financial and philosophical stand: he portrays it as a fight to keep modern NASCAR teams viable rather than just “professional fundraisers” scraping by on sponsorships.
