What Is a Prop Firm? A Plain-English Definition for New Traders
Key takeaways
- A prop firm is a company that lets traders trade its capital, or a simulated account backed by its capital, in exchange for a share of the profits, usually after the trader passes an evaluation.
- The prop firm most people find online is an evaluation business: you pay a fee, trade to a set of rules, and the firm pays you a profit split if you succeed.
- Most online funded accounts are simulated, with the firm paying real profit splits from its own money, and a firm that says this plainly is being honest, not deceptive.
- Every prop firm evaluation is built on three limits, a profit target, a daily loss limit and a maximum drawdown, and one breach usually ends the account.
- Only 1 to 3 percent of funded traders keep the account long term, so the fee should be treated as the cost of a test, not an investment.
- Before paying a first fee, confirm the drawdown type, the payout policy and the automation policy in writing on the firm's own site, because all of these vary by firm and change over time.
What is a prop firm? The short definition
A prop firm (proprietary trading firm) is a company that gives traders access to its capital, or to a simulated account backed by its capital, in exchange for a share of the profits, usually after the trader passes an evaluation. The trader does not deposit trading capital. Instead they pay a fee to be tested, and if they trade within the firm's rules, the firm pays them a percentage of the gains their trading produces. That is the short answer to what is a prop firm; the rest explains each part.
The word "proprietary" means the money belongs to the firm rather than to outside clients. That is the whole idea: the firm risks its own money on the traders it selects, and the trader is paid for skill instead of for capital.

Where the prop firm model comes from
The prop firm model exists in two very different forms: the traditional in-house trading desk and the online evaluation firm. The traditional desk hires traders as staff, trains them, and lets them trade the firm's real capital from an office; getting in is closer to a job interview than to buying a product.
The online evaluation firm flipped that cost onto the trader. Over the past decade or so, firms began selling remote evaluations anyone could purchase: pay a fee, trade a demo account to a rulebook, and earn a funded account if you succeed. This is the version you find when you search "what is a prop firm", and the one this article describes from here on.
The two forms share a name, not a business model. A traditional desk earns money when its traders profit. An evaluation firm earns money from fees and from the gap between what traders pay in and what it pays out, which is how it can afford to test thousands of strangers. That side is in [how prop firms make money](/blog/how-prop-firms-make-money).
How a prop firm works in practice: four steps
Almost every online prop firm runs the same four-step loop: pay a fee, pass an evaluation, receive a funded account, withdraw a share of the profits. Details differ by firm; the loop does not.
An evaluation is a demo trading period during which the trader must hit a profit target without breaking any risk rule; a demo account is a practice account that follows real prices with no real money at risk. Firms also call it a challenge, an assessment or a combine; in this article those words mean the same thing. A funded account is the account the firm opens for a trader who has passed. A profit split is the percentage of profits the trader keeps, commonly structured between 70 and 90 percent.
- Step 1, pay the fee: you buy an evaluation at a chosen account size. The fee is commonly a one-time payment, and some firms refund it after the first payout; confirm the refund policy in writing.
- Step 2, pass the evaluation: you trade a demo account until you reach the profit target, within the daily loss limit and maximum drawdown. Break a rule and the evaluation ends. The whole route is in [how to get a funded forex account](/blog/how-to-get-funded-forex-account).
- Step 3, receive a funded account: the firm opens a new account, sets the rules that apply to it, usually after identity verification.
- Step 4, withdraw a share of the profits: after a minimum period, commonly two to four weeks, you request a payout and the firm pays your split. What that first request looks like is in [the first payout timeline](/blog/first-payout-timeline).
What "funded" really means at an online prop firm
At most online prop firms, a funded account is a simulated account, and the profit split is paid from the firm's own money rather than from trades placed in the live market.
A simulated account is an account whose trades are recorded against real market prices but never sent to a real broker or exchange. The firm sees your performance exactly as a live account would show it and uses it to decide what to pay you. A few firms run genuine live accounts or copy their best traders into live capital, but the terms of service of the majority describe the funded stage as simulated.
This structure is not a scam by itself. The firm pays real money for real performance; what it does with its own capital is its business decision. It becomes a problem only when a firm hides the simulation, refuses payouts it agreed to, or changes rules after you pay. We separate the honest version from the rest in [are prop firms legit](/blog/are-prop-firms-legit).
The types of prop firm accounts: two-step, one-step and instant funding
Prop firms sell three main account types, and they differ mainly in how many evaluation phases stand between the fee and the funded account.
A two-step evaluation is an evaluation with two consecutive phases, commonly a higher profit target in phase one and a lower one in phase two, with the same loss limits in both. A one-step evaluation is an evaluation with a single phase, commonly a moderate profit target paired with a tighter drawdown. Instant funding is an account type where the trader pays a higher fee and skips the evaluation, but trades from day one under stricter limits and often a lower starting profit split.
- Two-step: lowest fee for the account size, longest path, and two chances to fail before you are funded.
- One-step: faster, but the tighter drawdown punishes a single bad week more than a two-step does.
- Instant funding: no test, highest fee, and often a scaling ladder that starts at a fraction of the advertised size. Read [instant funding vs evaluation](/blog/instant-funding-vs-evaluation) before choosing it for speed.
- Targets, drawdown types and fees change by firm and over time; confirm on the firm's site the week you buy.
The rules every prop firm has
Every prop firm evaluation is governed by three core rules, a profit target, a daily loss limit and a maximum drawdown, and a breach of the loss rules usually ends the account immediately. Firms add other rules on top; these three set the difficulty of any offer.
A profit target is the gain, expressed as a percentage of the starting balance, that the trader must reach to pass a phase, commonly structured between 5 and 10 percent. A daily loss limit is the maximum the account may lose in a single trading day before the firm closes it, commonly structured between 3 and 5 percent, measured on balance (closed trades only) or on equity (open trades included) depending on the firm. A maximum drawdown is the total loss, measured from the starting balance or from the account's highest point, that ends the account, commonly structured between 6 and 12 percent.
The maximum drawdown comes in two forms, and the difference matters more than any other rule. A static drawdown is a loss limit fixed at a percentage of the starting balance that never moves. A trailing drawdown is a maximum loss limit that moves up as the account makes money, which means early gains raise the floor beneath you.
- Minimum trading days: a required number of days with at least one trade, commonly structured between 3 and 10, so a single lucky day cannot pass a phase.
- Consistency rule: a cap on how much of total profit can come from one day, commonly 30 to 50 percent, at some firms and not others.
- Trading restrictions: limits on holding through news or weekends, on lot size, and on copy trading or automation, which vary by firm and platform.
- Every figure above is commonly structured, varies by firm and account type, and changes over time; the firm's own rules page is the only version that counts.
Who a prop firm makes sense for, and who it does not
A prop firm makes sense for a trader who already has a tested method, limited capital, and the discipline to trade smaller than the rules require, and it makes little sense for a trader still learning what their method is. The fee buys leverage on skill you already have; it does not create skill.
The most important number for a beginner: only 1 to 3 percent of funded traders keep the account long term. Most of the rest lose the funded account to the same loss limits that governed the evaluation. Passing filters for a good month; keeping the account filters for a repeatable process, and the second filter is far tighter.
Repeat challenge fees can add up to $2,400+ a year for a trader who buys a new evaluation after each failure. Treated as the cost of a test you take once or twice, the fee is reasonable; treated as a monthly habit, it is expensive. Whether it beats trading your own savings is worked through in [prop firm vs trading your own money](/blog/prop-firm-vs-own-capital).
- Good fit: a trader with a documented edge, a written risk plan, and a few months of consistent demo or small live results, who wants larger size than their savings allow.
- Poor fit: someone who has never traded and hopes the evaluation will teach them. It will, but a free demo teaches the same lessons without charging per attempt.
- Poor fit: someone who needs the payout to cover living costs; a first payout usually takes weeks, and no firm promises it will happen at all.
What to ask before you pay your first prop firm fee
Before paying any prop firm fee, read the rules page and the terms of service in full and get clear answers to the questions below, because they determine your odds of passing and of being paid. A firm should state each plainly on its own site; if it does not, the silence is an answer.
Automated trading is the use of a program, commonly called an expert advisor or bot, to place and manage trades on the trader's behalf. Some firms allow it, some restrict it to certain account types or platforms, and futures firms set their own policies, so confirm in writing before assuming.

Frequently asked questions
What is a prop firm in simple terms?
A prop firm is a company that lets you trade its money, or a simulated account backed by its money, and pays you a share of the profits. Most online prop firms first make you pass a paid evaluation to prove you can trade within their risk rules.
Do prop firms give you real money?
Usually not in the way beginners expect. Most online prop firms fund you on a simulated account and pay real profit splits from their own money based on your performance. The payout is real; the capital you trade is commonly simulated, and the firm's terms of service should say which it is.
How much does it cost to join a prop firm?
It depends on the account size and account type. Evaluation fees are commonly structured from under a hundred dollars for small accounts to several hundred for larger ones, and instant funding costs more because it skips the evaluation. Confirm current pricing on the firm's site, since fees change often.
Is a prop firm a scam?
No, not by definition, but some individual firms are. The model itself, paying a fee to be evaluated and earning a profit split if you succeed, is legitimate when the firm discloses that accounts are simulated, publishes its rules, and pays what it agreed to. The warning signs are hidden terms, denied payouts and rules that change after you pay.
Can a beginner pass a prop firm evaluation?
Yes, but the odds are low without a tested method, and passing is only half the problem. Only 1 to 3 percent of funded traders keep the account long term, so a beginner is better served by proving a strategy on a free demo first and treating the evaluation fee as the cost of a single test, not a repeated purchase.
