What is prediction market accounting?

“Prediction market accounting involves recording, reconciling, and reporting prediction-market trading activity for individual traders, trading firms, investment funds, and market makers. Professional operations may need transaction-level records covering executions, open and settled positions, trading venue and cash balances, fees, maker rebates, liquidity incentives, and transfers. These records support subledger and general-ledger accounting, period-end close, and financial reporting.”
