What is 99market?
A short remaining interval can make a small possible winning payout look large when annualized. Read price, time and available liquidity together; the APR is not one-trade profit or net return. It assumes a winning payout without compounding or automatic fee, slippage, tax or settlement-delay deductions.
The score asks a separate question about resolution clarity and market realism. Neither a high price nor a high APR raises it. Cached Gamma prices are a screening snapshot; the scheduled end can differ from when funds become redeemable.
