This latest contractual saga follows a protracted legal battle over his services for 2023, when Ganassi filed a lawsuit against its own driver after he signed a contract with McLaren in the summer of 2022.
A legal mediation led to him staying with Ganassi for this season, in which he seems certain to claim his second championship, but allowed him to drive McLaren Formula 1 cars and serve as the team's reserve F1 driver.
He seemed set to join the Arrow McLaren IndyCar squad for 2024 until now.
In a statement, Brown said: “I’m extremely disappointed that Alex Palou does not intend to honour his contractual obligations to race with us in IndyCar in 2024 and beyond.”
In a letter sent to McLaren employees after final practice at Indianapolis on Friday evening, first reported by the Associated Press, Brown wrote: “This is incredibly disappointing, considering the commitment he has made to us both directly and publicly and our significant investment in him based on that commitment.”
He also pointed out the “time, money and resources preparing to welcome Alex into our team because we believed in him and were looking forward to IndyCar wins with him”.
