Clickbait title, what's the news? Topstep Trader has been around for years.
Quite legitimate, but it's not very competitive price-wise. And what you actually are allowed to scale up to on a "$150K" combine is more in line with a $10K retail account.
The main purpose for it is to help people with zero discipline by enforcing strict rules.
With that said, one usually overlooked benefit is that unlike at a brokerage, you have zero responsibility for a negative balance if sh*t hits the fan (stuck in an illiquid position, black swan during a trade, etc.) That, to some, is worth bending over backwards to pass the combine and tolerate the high data fees.
