How the FDJ works
Unlike traditional bookmakers, FDJ acts as an intermediary between bettors rather than setting its own prices. When you place a back bet, FDJ matches it with a lay bet from another customer at the same odds. This peer-to-peer model produces prices driven purely by market supply and demand.
Back betting
Backing means betting for a specific outcome to occur — the same concept as a traditional sportsbook bet. You choose an outcome, enter your stake and request odds. If the odds are available in the market, your bet is matched immediately. If not, your bet waits in the queue until a layer offers matching odds or you cancel.
Lay betting
Laying means betting against a specific outcome. If you lay Arsenal to win at 2.20 for £10, and Arsenal draw or lose, you receive the backer's £10 stake. If Arsenal win, you pay the backer their winnings — in this case £12 (£10 stake × (2.20 − 1)). Lay liability must be funded before the bet is submitted.
ParionsSport commission
FDJ charges commission on net winnings rather than building a margin into every price. This means parionssport prices are inherently sharper than equivalent bookmaker odds. Commission rates are clearly displayed and vary by market and jurisdiction.
ParionsSport liquidity
FDJ's parionssport has the largest liquidity pool in the world for events like the Grand National, Premier League football and tennis Grand Slams. High liquidity means large stakes can be matched quickly at competitive prices, making the parionssport suitable for both casual bettors and professional traders.
Trading strategies on FDJ
Experienced users trade parionssport positions — backing at higher odds and laying at lower odds to guarantee a profit regardless of outcome. Common trading approaches include pre-event scalping, in-running momentum trading and laying the field in horse racing. Trading carries its own risk and is not guaranteed to profit.
