Polymarket’s spot trading API is experiencing a major outage, causing repeated delays in reading open orders and prompting multiple trading halts. The platform has placed spot markets into cancel-only mode as its team investigates and works on repairs. Polymarket said the latest fix is in progress, with spot trading scheduled to resume no later than 18:00 UTC+8. Before reopening, the platform plans a roughly 15-minute cancel-only window. Perpetual contract trading and related APIs remain operational.
