We are currently investigating an issue affecting options markets on the Bullish exchange. A technical error caused an abnormally large number of strike prices to be generated for the December 25, 2026 options expiry, resulting in the creation of option markets with extremely high and invalid strike prices. As a precautionary measure, we have halted trading on the affected option markets to prevent any incorrect trades from being executed. Our team is fully engaged in resolving the issue as quickly as possible. We apologize for any inconvenience caused and will provide updates as soon as they become available.
