What happened: Cadillac's Formula 1 operation has a U.S. driver change described as confirmed, per TheJudge13. The move lands ahead of its first home race in Austin.

Why it matters: An American driver in an American entry carries commercial and crowd weight, especially at COTA. It follows a debut campaign still seeking its first championship point after Monaco.

What to watch: Watch for formal team confirmation with terms, timing and race debut.
