Kyle Larson Approves IndyCar-NASCAR Doubleheaders After Phoenix

Kyle Larson just gave the motorsports world exactly what it needed: a co-sign. After one of the most electric racing weekends in recent memory, the defending NASCAR Cup champion made his feelings crystal clear.

He wants more IndyCar–NASCAR doubleheaders. And after what went down at Phoenix Raceway on March 7–8, 2026, it’s hard to argue with him.

Two days. Two races. One team absolutely owning the whole thing. Larson didn’t sugarcoat it. Standing in the aftermath of a weekend that had fans buzzing from coast to coast, he looked straight at IndyCar and said, “Those guys deserve to be the premier division.”

That’s not a throwaway quote. That’s a man with credibility, a Cup champion, a Hendrick Motorsports pillar, lending his name and his reputation to the idea that open-wheel and stock car racing belong on the same stage, the same weekend, at the same track. When Larson talks, people listen. And right now, he’s talking about the future of motorsports.

1. Phoenix Delivered Big Time

Let’s set the scene. IndyCar hadn’t raced at Phoenix since 2018. Eight years away from the one-mile oval. When they came back for the Good Ranchers 250, the expectations were high and Josef Newgarden didn’t just meet them, he crushed them. Newgarden crossed the line first, with teammate David Malukas starting from pole and finishing third. A Penske 1-3 in IndyCar. Dominant doesn’t begin to cover it. Then came Sunday. Ryan Blaney strapped in for the NASCAR Cup Series Straight Talk Wireless 500 and went to work. It wasn’t clean. There was late-race drama, there always is at Phoenix, but Blaney held it together and snapped Tyler Reddick’s three-race winning streak in the process. Another Penske car, another Penske win. Roger Penske’s team swept the entire weekend. In their 60th anniversary season. If you wrote that in a movie script, someone would tell you it was too on the nose.

2. Why This Weekend Actually Matters

Look past the trophy haul, and you’ll see something bigger happening here. Doubleheaders between IndyCar and NASCAR have been talked about for years. The concept sounds great in theory: two fanbases, one weekend, massive energy, but logistics always got in the way. Scheduling conflicts, media access headaches, the usual behind-the-scenes friction that kills good ideas before they breathe. Phoenix changed that conversation. The atmosphere that weekend felt like a motorsports festival. Fans who came for NASCAR stayed for IndyCar. IndyCar fans got a live look at NASCAR’s biggest stars. Everyone left with more than they bargained for. That kind of organic crossover is exactly what both series have been chasing for years, and Phoenix just handed them a working blueprint.

3. What Comes Next for Larson and the Double-Header Push

Momentum is real in sports. Right now, it’s pointing directly at more of these events. Insiders within NASCAR are already floating ideas, such as a streamlined “one waiver” system that would make it easier for media and teams to operate across both series on shared weekends. Other tracks, Texas, Michigan, and Indianapolis, are reportedly evaluating whether they can pull off something similar. And with Larson’s endorsement carrying serious weight in the paddock, that conversation just got louder. The man just won a Cup championship. He’s attempted the Indianapolis 500. He understands, more than most, what it looks like when two worlds of racing collide and produce something genuinely great. His support isn’t just a nice gesture, but it’s a signal to promoters, broadcasters, and sanctioning bodies that the demand is real. Here’s what Phoenix proved: fans don’t just want racing, they want events. They want to talk about the weekends on Monday morning. They want the kind of electric, chaotic, unpredictable energy that only happens when the stakes are high and the competition is fierce. A Penske sweep across two different racing series, a defending Cup champion openly championing a competitor’s league, and one of the best short-track weekends in years is a story that writes itself. Larson wants more. The fans want more. And after Phoenix, the case for more IndyCar–NASCAR doubleheaders has never been stronger.
