The house ledger
A prop firm makes money in two ways: fees from people who fail, and a share of what winners make. It loses money on funded seats that go wrong. Here is every flow, and a calculator so you can see which side wins with your own numbers.
Every way money moves
| Who | What happens | When |
|---|---|---|
| You, taking the exam | Pay the season's exam fee in USDC. It goes to the pool when the exam is graded. | When you start an exam |
| The pool | Funds a seat wallet for every exam that passes, up to a cap on how much can be out at once. | When the seat is claimed |
| The program | Closes a seat at 5% down in a day or 10% down in total, marked at exit value. | The moment a line is hit |
| You, funded | Take 80% of profit through the split. 20% goes back to the pool. | When you call the split |
Run the pool yourself
Each seat here is $10,000. A seat that ends at the cut is counted at the worst case, a full 10% loss. These are your inputs, not a forecast. Real figures will be read from the chain once exams run.
Per 100 exams
- Exam fees
- $18,000
- 20% of winners' profit
- $840
- Seats that end at the cut
- -$7,000
With these numbers the pool stays ahead and every winner still gets paid.
The part nobody puts on the poster
Across prop firms, about 14 in 100 exams pass and about 7 in 100 traders ever get a payout (FPFX Tech data, 100,000+ traders across 10 prop firms). PROPFUN does not change the odds of trading well. It changes who can check the grade: the rules, every position and the result are on Solana, so a fail comes with the reason attached.
