What Is a Proprietary Trading Firm?

A proprietary trading firm — "prop firm" for short — is a company that puts its own money into the markets to profit from price moves, rather than earning fees or commissions from outside clients. "Proprietary" simply means on its own account. That single idea covers a surprisingly wide range of businesses, from secretive Wall Street quant shops to online firms that fund retail traders after a challenge.

Because the term stretches so far, it helps to split it into two models: the traditional institutional prop firm and the modern retail "funded account" prop firm. They share the label and the basic idea of trading firm capital, but they differ enormously in who trades, whose money is truly at risk, and how a trader gets in. Understanding both is the fastest way to know which one a given article, ad, or recruiter is actually talking about.

The original meaning of "prop firm" is an institutional trading company that trades its own real capital with a team of hired, salaried traders and engineers. Names like Jane Street, Optiver, Susquehanna (SIG), Jump Trading, and IMC dominate this world. They run market making, arbitrage, and high-frequency and quantitative strategies across equities, options, futures, and crypto, deploying serious technology and risk infrastructure.

Getting in means getting hired, not buying a challenge. These firms recruit competitively — often math, CS, and finance talent — and pay traders a salary plus a share of the profits (a bonus) while the firm bears the actual financial risk on real balance-sheet capital. There is no evaluation fee; instead there is an interview gauntlet. This is the model finance professionals mean when they say they "work at a prop firm."

The second model — and the one most people now find online — is the retail funded-account prop firm. Firms such as Lucid Trading, Topstep, and Apex Trader Funding let anyone attempt to trade "firm" capital by paying for an online evaluation (a challenge). Pass the profit target within the drawdown rules and you receive a funded account to trade remotely from home, keeping the large majority of the profits.

A key distinction: in this model the account is typically simulated (a demo environment) until payouts are earned, and the firm's revenue comes substantially from evaluation fees as well as from the trading. You are not an employee, there is no salary, and you access the opportunity by fee rather than by hiring. For a full deep-dive on this retail model specifically, read [what is a prop firm](/guides/what-is-a-prop-firm).

Who trades and how you get in. Institutional firms hire vetted employees; retail firms let anyone pay for an evaluation. Whose money is at risk. Institutional firms risk real firm capital; retail funded accounts are usually simulated until a payout, so the firm's direct market risk is smaller and its fee income larger. Pay. Institutional traders get a salary plus bonus; retail funded traders get no salary and keep a profit split (often 80–90%).

Location and scale. Institutional trading happens in offices with heavy infrastructure; retail funded trading is remote and self-directed. Products. Institutional firms trade broadly and quantitatively; retail futures firms center on index futures like ES and NQ. Neither is "fake" — they are simply different businesses sharing a name. Knowing which one is in play tells you whether you need a resume or an evaluation fee.

In everyday online conversation — YouTube, Reddit, ads — "prop firm" almost always means the retail funded-account model, because that is the version an ordinary trader can actually access without being recruited. When you see promises of a "funded account" after passing a "challenge," that is the retail model. To go deeper on it, see [what is a funded trading account](/guides/what-is-a-funded-trading-account) and [how prop firms make money](/guides/how-do-prop-firms-make-money).

In finance and career contexts, "prop firm" usually means the institutional model — a competitive employer trading its own book. So the same two words can describe either a job you interview for or a product you buy. When someone uses the term, the quickest clarifier is: do you get hired, or do you pay to attempt an evaluation? That single question tells you which world you are in.

In short, a proprietary trading firm trades its own capital to profit from the trades themselves. The institutional version hires salaried traders to risk real firm money; the retail funded-account version lets anyone pay for an online evaluation to trade a mostly simulated account remotely for a profit split. Both are legitimate; they just serve different people and work in different ways.

If your goal is the accessible route, focus on the retail model and vet firms carefully — see [are prop firms worth it](/guides/are-prop-firms-worth-it). Important: retail funded accounts are simulated until you are funded and paid, trading leveraged futures carries a substantial risk of loss, and nothing here is financial advice — it is educational information to help you understand what "prop firm" actually means.
