Yes, but at that point it’s not really voltage anymore. It would be more like a rapidly expanding cloud of electrons ionizing anything it came across.
It could be more focused though a magnetar though, and a magnetar might conduct the ionised plasma nearby, or even through the galaxy in interactions with the local supermassive black hole.
Everything is a good conductor if the voltage is high enough
Neutron star?
