Proprietary trading firms primarily make money through two main avenues: direct profits from trading their own capital and revenue generated from their trader evaluation programs. For modern online prop firms, a significant portion of income comes from the fees traders pay to take on a “challenge” or “evaluation.” Since many aspiring traders do not pass these evaluations, the collected fees form a substantial and stable revenue stream. Successful traders who pass the evaluation then generate trading profits, which are shared between the trader and the firm, creating a second layer of income for the company.

What Exactly is a Proprietary Trading Firm?
A proprietary trading firm, or prop firm, is a financial institution that trades stocks, derivatives, currencies, commodities, and other instruments with its own money, rather than using clients’ capital. The primary goal is to generate direct profits from its market activities. Unlike a hedge fund or mutual fund, they do not manage outside investors’ money and therefore keep all the profits they make. This structure gives them the freedom to employ a wide range of aggressive and complex strategies.

The landscape of proprietary trading has evolved dramatically. Understanding the two primary types of firms is crucial to grasping their different revenue models.
The Traditional Model vs. The Modern Online Firm
Traditional prop firms often have physical offices where traders work on a trading floor. These firms, like Jane Street or Susquehanna International Group (SIG), typically hire traders with elite academic backgrounds. They provide significant capital and sophisticated technology, focusing on quantitative strategies, market making, and arbitrage. Their revenue is almost entirely derived from trading profits.
Modern online prop firms, which have surged in popularity, operate on a completely different model. They cater to a global pool of retail traders, offering them the chance to trade company capital remotely after passing a multi-stage evaluation process. This model, utilized by firms you might find through Cointracts.com, democratizes access to trading capital but also introduces new revenue streams, primarily through evaluation fees.
The Core Business: Generating Direct Trading Profits
At its heart, the most straightforward way a prop firm earns money is by making successful trades. Using their substantial capital reserves, they engage in various strategies to outperform the market. The profits generated are the firm’s own and are not shared with any outside clients or investors.
Strategies That Drive Direct Profitability
Prop firms deploy a diverse arsenal of trading strategies, often powered by advanced technology and quantitative analysis. Some common approaches include:
- High-Frequency Trading (HFT): Executing a massive number of orders in fractions of a second to capitalize on tiny price discrepancies.
- Statistical Arbitrage: Using statistical models to find and exploit pricing inefficiencies between related financial instruments.
- Market Making: Simultaneously providing buy (bid) and sell (ask) prices for a security, profiting from the difference, known as the bid-ask spread.
- Global Macro: Making large, directional bets on the price movements of entire markets based on macroeconomic and political events.
The Role of Capital and Leverage
A prop firm’s greatest asset is its capital. Having a large pool of money allows it to take meaningful positions that can generate substantial returns. Furthermore, firms use leverage to amplify their trading power, turning small market movements into significant gains. However, leverage is a double-edged sword, as it also magnifies losses, making robust risk management an absolute necessity for survival and profitability.
The Evaluation Fee Model: A Powerful Revenue Engine
For the modern online prop firm, the evaluation or “challenge” process is a cornerstone of their business model. Aspiring traders pay a one-time, non-refundable fee to participate in an evaluation where they must prove their trading skills by meeting specific profit targets while adhering to strict risk parameters, such as maximum daily loss and overall drawdown limits.
Why Do Traders Pay for Challenges?
The appeal is straightforward: access to significant trading capital. A talented trader with a small personal account may be limited in their earning potential. By passing a challenge, they can gain access to an account worth $50,000, $100,000, or even more. The evaluation fee is seen as a small investment for the opportunity to manage a large sum of money without risking personal funds beyond the initial fee.
The Economics of Challenge Fees
This is where the business model becomes particularly lucrative. A high percentage of traders who attempt these challenges fail to meet the stringent requirements. Industry estimates suggest pass rates can be as low as 5-10%. When a trader fails, the firm simply keeps the fee. For a firm processing thousands of challenges per month, these fees create a massive, consistent, and low-risk revenue stream that often surpasses the profits generated from their funded traders.
Are You Trading on a Live or Demo Account?
A crucial detail many traders overlook is that even after passing a challenge, many online prop firms place them on a simulated (demo) account initially. The firm mirrors the trader’s trades in its own live institutional account. The trader is then paid their profit split based on the performance of the demo account. This insulates the firm from a newly funded trader who might immediately become reckless. Only consistently profitable traders are eventually migrated to a true live account.
Profit Splits: Sharing Success with Funded Traders
Once a trader successfully passes the evaluation phase and becomes a “funded trader,” a new revenue dynamic comes into play: the profit split. When the trader generates profits on their funded account, those profits are divided between the trader and the firm according to a pre-agreed ratio.
How Do Profit Splits Work?
Profit splits are heavily skewed in favor of the trader to attract top talent. It is common to see splits of 80/20, 90/10, or even higher, where the trader keeps the majority of the profits. For example, if a trader with an 80/20 split makes $10,000 in a month, they receive $8,000, and the firm receives $2,000. This might seem small, but when multiplied across hundreds or thousands of profitable traders, it becomes a significant and scalable income source.
The Scaling Plan Incentive
To retain top talent and incentivize consistent performance, most firms offer “scaling plans.” If a trader remains consistently profitable over a period, the firm will increase the capital in their account. A trader might start with a $100,000 account and, after meeting certain milestones, be scaled up to $250,000, $500,000, or more. This increases the firm’s potential earnings from that trader’s profit split while further motivating the trader to perform well.
Uncovering Ancillary Revenue Streams
Beyond the two main pillars of trading profits and evaluation fees, some firms build additional income sources to diversify their revenue. While less common in the online model, these can be significant for certain types of firms.
Monthly Subscriptions and Platform Fees
Some firms may charge a monthly “desk fee” or subscription for access to their trading platform, premium data feeds, analytical software, or educational resources. This creates a recurring revenue stream independent of a trader’s performance. However, the most popular online firms today tend to avoid this model, focusing instead on the one-time evaluation fee.
Data Fees and Add-Ons
In some cases, firms might offer optional add-ons during the evaluation purchase. This could include things like a faster data feed, the ability to hold trades over the weekend, or more lenient drawdown rules, each for an additional fee. This allows the firm to upsell traders at the point of sale.
What is the Complete Business Model of a Prop Firm?
To fully understand how prop trading firms make money, it is helpful to visualize the different components of their business model. The emphasis on each revenue stream varies significantly between the traditional and modern online structures.
The following table illustrates the primary differences in their profit-generating activities:
| Revenue Source | Traditional Prop Firm (e.g., Jane Street) | Modern Online Prop Firm (Remote/Challenge-Based) |
|---|---|---|
| Direct Trading Profits | Primary and often sole source of revenue. Uses firm’s institutional capital. | Secondary source. Profits are generated by funded traders and the firm’s own trading desk. |
| Evaluation/Challenge Fees | Non-existent. Traders are hired as employees. | A primary and highly significant source of revenue. |
| Profit Splits | Non-existent. Traders receive a salary and performance-based bonus. | A key secondary revenue source, directly tied to trader success. |
| Subscription/Data Fees | Internal cost; not a revenue source. | Can be an ancillary revenue source for some firms. |
Risk Management: The Bedrock of Sustainable Profitability
A prop firm’s ability to make money is directly tied to its ability to not lose money. Aggressive risk management is not just a guideline; it is the core of the entire business. Without it, a few bad trades could wipe out a firm’s capital.
Why Strict Rules (Like Daily Drawdown) Are Essential for the Firm
The strict rules imposed during evaluations—such as maximum daily loss and maximum total drawdown—serve a dual purpose. First, they filter out traders who lack discipline. Second, and more importantly, they are the same rules that protect the firm’s capital once a trader is funded. By forcing traders to operate within these tight constraints from day one, the firm ensures that no single trader can inflict catastrophic damage on its capital base. These rules are the firm’s insurance policy.
How Does a Trader’s Success Impact the Firm’s Bottom Line?
While failed challenges provide a steady stream of income, a firm’s long-term reputation and growth potential are built on the success of its funded traders. A cohort of consistently profitable traders is the ultimate asset.
Beyond Profit Splits: The Value of a Consistently Profitable Trader
A successful trader does more than just generate a profit split. They validate the firm’s business model and serve as powerful marketing tools. Testimonials and success stories attract more aspiring traders to take on the evaluation, feeding the top of the revenue funnel. Furthermore, top-performing traders generate reliable, scalable profits for the firm with minimal risk, as their strategies have already been proven effective under the firm’s rules.
This is precisely why finding the right partnership is so important for a trader’s career. Navigating the landscape of prop firms can be daunting, but platforms like Cointracts.com play a vital role in this ecosystem. By aggregating and vetting various prop firms, they empower traders to find reputable partners that offer genuine growth paths, fair profit splits, and supportive trading environments, creating a scenario where both the trader and the firm can thrive.
Do Prop Firms Profit from Failed Challenges?
Yes, absolutely. For the vast majority of online proprietary trading firms, revenue from failed challenges is a critical, and often the largest, component of their income. The business model is statistically designed around the fact that a large percentage of participants will not be able to meet the profit targets within the specified risk limits. This creates a predictable financial cushion that allows the firm to fund the small percentage of traders who do succeed and cover operational costs while ensuring overall profitability.
Choosing the Right Firm: Aligning with Their Business Model
As a trader, understanding how a firm makes its money helps you assess its legitimacy and whether its interests are aligned with yours. A firm that relies exclusively on challenge fees with an impossibly difficult evaluation may not be invested in your long-term success.
What to Look for in a Reputable Prop Firm
When selecting a firm, look for transparency and a clear path to growth. Key indicators of a reputable firm include:
- Reasonable Rules: The trading objectives should be challenging but achievable.
- High Profit Splits: A generous split (80% or more) shows the firm wants you to succeed.
- Clear Scaling Plans: A roadmap for capital increases rewards consistency.
- Strong Community and Support: Good firms provide customer service and foster a supportive community.
- Positive Reviews: Look for authentic feedback from other funded traders.
By understanding the intricate mechanics of how prop trading firms make money, from direct market profits to the economics of the evaluation model, traders can make more informed decisions, identify the best opportunities, and position themselves for success in this dynamic industry.
