Prime Video NASCAR Cup Series announcers Adam Alexander, Dale Earnhardt Jr. and Steve Letarte are back for 2026, and the booth stays together as the broadcast package shifts to TNT Sports. Viewers of the NASCAR Cup Series will hear the same three voices across the next five races, starting at Sonoma Raceway.
The five-race Prime Video run ended this past weekend at Qualcomm Circuit on Naval Base Coronado. TNT Sports now takes over a five-race summer slate that includes the entire In-Season Challenge, the five-week bracket that debuted a year ago and was won by Ty Gibbs.
Alexander Stays On Lead Duty
Alexander returns in the same role he had when Prime Video joined the Cup Series schedule in 2025. He also works full-time as the lead announcer for the O'Reilly Auto Parts Series on the CW Network, which keeps him in a familiar race-call rhythm while the Cup Series package changes hands.
The booth itself did not change when the calendar flipped from one part of the broadcast deal to another. Alexander, Earnhardt and Letarte are set to stay together for Sonoma, Chicagoland Speedway, EchoPark Speedway, North Wilkesboro Speedway and Indianapolis Motor Speedway.
TNT Sports Takes Five Races
The new window is short and fixed. TNT Sports gets five races, and those races carry the In-Season Challenge from start to finish, so the stretch is built around one consecutive run rather than scattered dates.
That structure leaves viewers with the same announcers calling every race in the package while the network label changes underneath them. The odd part is the language around it: the booth is treated as the new TNT Sports setup, even though it is the same Prime Video trio moving straight across the split.
What Sonoma Starts
The Toyota Save Mart 350 at Sonoma Raceway opens the TNT Sports portion this weekend. From there, the same booth follows the Cup Series through the next four stops, giving the midseason block a single on-air identity even as the rights package rotates to a different home.
For viewers, the practical change is simple. The race coverage moves from Prime Video to TNT Sports, but the voices on the call remain Alexander, Earnhardt and Letarte for the full five-race stretch.
