The $25,000 rule is gone
Yes — and it will probably cost you the $500. Both halves of that sentence deserve their evidence.

The repeal of the pattern day trader rule (June 4, 2026) removed the legal barrier: at brokers that have implemented the new intraday margin standards, no rule stops a $500 margin account from day trading — though margin itself still requires $2,000 of equity, so a $500 account day trades on settled cash, cycling funds at T+1. The headline version stops there. The arithmetic continues.
Our computed minimum for US day trading is $1,000, set by the cost term: at beginner frequency (about 40 round trips a month) spread and slippage at the smallest sensible sizes run about $20 a month. On a $500 account that is 4% of the account, every month, before your strategy makes or loses anything — a hurdle of roughly 48% a year that your trading must clear before it earns its first dollar. Position size is not the binding constraint at $500; the toll is.
The full-market research counts about 5% of day traders profitable after costs (Barber, Lee, Liu & Odean), and Brazil's study of persistent day traders found 3% made money over a year. Those studies describe traders at all sizes; undercapitalised traders face the same market plus a proportionally larger cost stack. The rule change widened the door. It did not narrow the odds.
If you day trade $500, do it as what it is: a learning account with tuition of up to $500, the smallest sizes your broker allows, every trade journaled, and a stop written in advance — the total amount you accept paying for the education. If that framing feels like a letdown, compare it with the alternative sequence our checker usually prints: demo at $1,000 size until the journal holds 50 trades, save the second $500, and start at the computed minimum with a record that means something. Same destination; the tuition buys more on the second road.
