The basic structure

A proprietary trading firm — commonly “prop firm” — evaluates a trader’s skill and then provides either firm capital or a simulated trading environment, paying out a share of profits in return.

The trader pays an upfront evaluation fee and completes a challenge under strict rules (profit target, max drawdown, daily loss limit). On success, the trader receives a funded account and a profit split.

The revenue model — honestly

A prop firm’s revenue comes from two sources:

  1. Evaluation fees — collected from every trader who attempts the challenge.
  2. Profit-split residual — the firm’s share (typically 20–50%) of successful traders’ profits.

In practice, the majority of revenue for most firms comes from evaluation fees, because the majority of traders fail the challenge. Specifically, this structure can incentivize the firm in ways where trader losses are firm profits. Treat that with realism rather than cynicism — it does not mean the firms are dishonest, only that you should read their rules with the structure in mind.

”Simulation” versus “live execution”

Most prop firms state publicly that trading occurs in a simulated environment, with no orders routed to real markets. This is what allows the firm to legally avoid being classified as a broker in many jurisdictions.

For you as the trader, the practical implication is that spreads and slippage may not perfectly mirror live markets. By contrast, a few firms (notably Topstep’s Live Funded path) graduate top performers to real-market execution after sustained performance.

Real risks

  • Jurisdiction. Most overseas prop firms are not registered with your local financial regulator. Recourse in a dispute is limited.
  • Enforcement history. In 2023, MyForexFunds was shut down by Canadian (OSC) and US (CFTC) regulators. Even at the largest scale, prop firms can be subject to enforcement actions.
  • Rule changes. Terms can change at the firm’s discretion. Read the agreement; re-read it once a quarter.
  • Tax treatment. Varies by jurisdiction. Consult a licensed tax professional in your country.

Checklist before you commit

  • Is the firm at least three years old, ideally five?
  • Are there multiple, continuous payout proofs — not just a single screenshot?
  • Has the firm avoided major enforcement actions in major jurisdictions?
  • Are the terms publicly available, with a clear change-notification process?
  • Does the firm avoid “guaranteed to earn” or “anyone can pass” language?

Bottom line

A prop firm is not a loan and not a job. It is a performance contract: you pay to demonstrate skill under the firm’s rules, and if you succeed, you receive a share of the profit.

In short, speculation is real, and losing the evaluation fee is a real possibility. PROP NAVI rates each firm on trust and transparency, but the final decision is always yours.
