Other notable premarket gainers included Cheetah Net Supply Chain Service, Delixy Holdings, Generation Income Properties, Pop Culture Group, BTC Digital, Amaze Holdings, Securitize, 908 Devices and Cybin. Xenon Pharmaceuticals led decliners after pausing enrollment of new patients in ongoing psychiatry studies, while Datasea Intelligent Technology, Firefly Neuroscience, Abits Group, RenX Enterprises, AGM Group, Wheeler Real Estate Investment Trust, Frontline, Biohaven and Nucor also fell.
