Prop Firm

A prop firm, short for proprietary trading firm, is a company that allocates its own capital to traders who prove their skill, then shares the resulting profits. The modern retail prop model works through a challenge: a trader pays a fee to attempt an evaluation with defined profit targets and risk limits, and on passing receives a funded account on which they trade firm capital and keep an agreed profit split. This challenge-and-funding structure makes the prop firm a distinct business entity, separate from a broker, with revenue coming from both challenge fees and a share of trader performance.

The defining constraints of a prop firm are its risk rules, especially the drawdown limits that cap how much an account can lose before the evaluation or funded account is breached. These rules protect the firm's capital and shape how traders behave, and they are also what differentiate one firm's offer from another. Because the firm earns on challenge sales as well as profit splits, its economics depend on attracting a steady flow of evaluation buyers, which is where partner channels become central.

Affiliate channels are a primary acquisition route for prop firms because challenges are sold to a global, marketing-driven audience. Affiliates earn commissions on challenge purchases through a prop-firm affiliate program, and some firms also work with signal providers and educators who funnel traders toward evaluations. The prop firm is the entity being promoted, while the affiliate program is the commercial structure built on top of it, so understanding the firm as a business clarifies what affiliates are actually selling.
