What Is a Prop Firm?

A proprietary trading firm — a prop firm — trades its own capital instead of managing client money. In the modern retail form, the firm recruits traders through a paid evaluation, funds the ones who pass, and splits the profits with them. That evaluation model is what separates today's funded-trader firms from the institutional prop desks the name originally described.

The original meaning, and what changed

Proprietary trading historically meant a bank or trading house putting its own balance sheet at risk, staffed by employed traders on a salary and bonus. Those desks still exist. What most people now mean by 'prop firm' is something different: a retail-facing business that sells an evaluation, funds successful candidates on a profit split, and never employs them.

How the evaluation model works

  1. 1

    The trader buys a challenge

    A one-time fee for an account with a defined size and a rulebook: a profit target, a daily loss limit, an overall drawdown limit and usually a minimum number of trading days.

  2. 2

    Phase one — hit the target without breaking a rule

    Most firms use a profit target of roughly 8–10% with a daily drawdown around 5% and overall drawdown around 10%. Breaking any limit ends the attempt.

  3. 3

    Phase two — repeat at lower intensity

    A second phase with a smaller target, typically half the first, confirms the result was not a single lucky position. Some firms sell one-phase evaluations at a higher fee.

  4. 4

    Funding and profit split

    The trader receives a funded account and keeps a share of profits — commonly 70% to 90%, with the highest splits used as a competitive lever. The same drawdown rules continue to apply.

  5. 5

    Payout

    Profits are withdrawn on a schedule, typically every two to four weeks, subject to identity verification and the firm's payout policy.

How prop firms make money

Two revenue lines, and the balance between them is the whole business model.

  • Evaluation fees. Most candidates do not pass. That is not a scandal — it is the arithmetic of a difficult target with a hard drawdown limit — but it does mean evaluation revenue is the dominant line for most firms.
  • The firm's share of funded-trader profit. Smaller, more volatile, and the line that signals a healthy firm: a business earning meaningfully from trader performance is aligned with its traders rather than with their failure.

The distinction matters legally as well as commercially. A prop firm is not holding client funds, which is why its regulatory position differs from a broker's — and why that position varies so much between jurisdictions.

What separates a durable firm from a short-lived one

  • Rules that are modelled before they are published, and not changed retroactively.
  • Payouts that arrive on the stated schedule. This is the single most-discussed factor in trader communities.
  • A risk engine that enforces limits automatically and identically for everyone, rather than by manual review.
  • Clear, unambiguous rule text. Most disputes are wording problems, not trading problems.
  • Revenue that is not entirely dependent on failure rate.

The infrastructure underneath

Operationally, a prop firm is a trading platform, a challenge engine, a real-time risk system, an identity-verification flow and a payout ledger, all agreeing with each other. Firms either build that stack or license it. PropsEngine supplies it as white-label infrastructure, so the founding team can focus on the rulebook, the brand and the traders.

Frequently asked questions

What does prop firm stand for?
Proprietary trading firm — a firm that trades its own capital rather than managing money for clients.
Are prop firms regulated?
It depends on the jurisdiction and on how the firm is structured. Because a prop firm is not holding client deposits, it often falls outside the broker licensing regime, but this varies significantly by country and is an active area of regulatory attention.
Why do prop firms charge for the evaluation?
The fee covers the cost of running the evaluation and filters for commitment. It is also, for most firms, the primary revenue line — which is why the ratio of evaluation revenue to trader-profit revenue is a useful signal of how a firm is really run.
What is a typical profit split?
Between 70% and 90% to the trader. Splits above 90% are used as a marketing lever and are usually paired with tighter rules or higher evaluation fees.
What is the difference between one-phase and two-phase challenges?
A two-phase evaluation asks the trader to hit a target twice, the second time at a lower level, which filters out single lucky trades. One-phase evaluations are faster and easier to sell, so they carry a higher fee or tighter drawdown rules to compensate.
