A プロップファーム is a company that provides traders with capital to trade financial markets. The firm supplies the money, the trader executes the trades, and any profits are shared between them according to a pre-agreed percentage.

The model works well for both parties. The firm puts its capital to work through skilled traders without those traders needing to use their own savings. The trader gains access to a much larger account than they could typically fund themselves, which means greater potential returns from the same trading strategy.

Prop firms operate across many different markets, including forex, futures, cryptocurrencies, and equities. Some firms pay traders from simulated account profits, while others place real trades in live markets. Understanding which model a firm uses is important, because it affects how payouts are calculated and where the money actually comes from.
