Onyx Futures is a US futures prop firm registered in Illinois that launched in 2026, offering simulated futures evaluations on CME, COMEX, NYMEX, and CBOT contracts through Rithmic. Every account uses end-of-day trailing or static drawdown rather than intraday trailing, and the firm publishes an unusually detailed public rule book covering its Sapphire, Flex, Gold, and Direct account tracks.
