SizeProp

SizeProp is a trading services company based in the Cayman Islands that provides traders with access to proprietary capital across various financial markets, ensuring a risk-managed trading environment. Founded in 2025, SizeProp operates out of George Town, Cayman Islands, offering a trading evaluation program to aspiring traders. The company has successfully executed 1 deal as of May 19, 2026. SizeProp is governed by SIZ EDU Limited, facilitating a unique approach to simulated trading services for its users.

SizeProp offers a comprehensive suite of proprietary trading services, primarily focusing on providing access to prop capital for traders in various financial markets, including cryptocurrencies, stocks, metals, and forex futures. The company's core product is a trading evaluation program where users select an account size, pay a one-time fee, and undertake a trading test to demonstrate their ability to meet profit targets while adhering to defined drawdown limits. Upon successful completion of the test, traders can access up to USD 100K in prop capital and retain up to 95% of their generated profits. SizeProp serves a diverse customer base of nearly 4,000 traders globally, with operations designed for markets in North America, Europe, and parts of Asia where retail and professional trading activity is significant.

The company operates under the jurisdiction of SIZ EDU Limited, providing simulated trading services rather than live market trading, ensuring a risk-managed environment for aspiring traders. SizeProp's revenue model is structured around the fees collected from trading evaluations, which allow participants to access prop capital upon passing a trading test. The company charges a one-time fee for different evaluation account sizes, notably USD 399 and USD 899 for account sizes of USD 100K, with promotional discounts available. This fee facilitates an educational and simulated trading experience, where clients can experiment without risking their own capital.

Once traders pass the evaluation, they are funded with prop capital and rewarded with a payout structure that allows them to withdraw up to 95% of the profits generated. Revenue is generated directly from trader enrollments in the evaluation programs, creating a streamlined transaction structure that supports both B2C and B2B interactions within the trading community. In May 2026, SizeProp raised an undisclosed amount of pre-seed funding led by new investor Igloo, Inc. The company plans to utilize this funding to enhance its trading evaluation programs and expand its product offerings.

SizeProp is also targeting geographic expansion into additional markets in Europe and Asia, aiming for completion by the end of 2027.
