If it's consumer marker where less cost matters a lot, there won't be a US competitor. DJI has home-turf, scale, and first mover advantage there, and a US competitor can maaybe match DJI in price.
In technology/autonomy? Skydio beat them years ago (https://www.skydio.com/). They launched as a consumer drone but I guess recently realized how consumer market in west isn't as profitable as enterprise/defense market so they shut down their consumer division. Skydio founders were pioneers in autonomous aerial vehicles, and it's not surprising they beat everyone else in autonomy. When they launched their first drone a few years ago, they were doing outdoor vision based autonomy for drone using on board compute only - it's an insanely hard problem, especially when you want to do in reliably in a product and not in a lab setting for nice videos. They did it and blew everyone away. DJI fan boys will say 'oh but DJI had autonomy too'. No they didn't, at best they had feedback based obstacle avoidance.
I often tell my friends, one of my biggest regret was not signing up for an internship at Skydio back in 2018. They came to UIUC for recruiting, and they didn't realize their product yet. Back then I was a dumb first year grad student, I didn't check the founders background, and naively thought it was yet another dumb drone company trying to get some VC money by pitching something they'd obviously fail it. I've never been so wrong.
