Topstep is one of the oldest names in futures prop trading, billed as a monthly subscription ($49-$199/mo depending on account size) rather than a one-time fee.
As of April 2026, Topstep is named in an active federal lawsuit alleging a “systematic and deceptive scheme” involving shifting rules and profits held in an effectively inaccessible reserve account, on top of a history of Better Business Bureau complaints about account terminations arriving just before payout eligibility. Topstep has also taken legal action against at least one public critic, resulting in that person being barred from discussing the firm publicly — worth knowing given how much of prop-firm due diligence relies on public trader reporting.
