At least not right now.
As of last night, Tesla is no longer taking reservations for the Cybertruck. Perhaps the millions who have already reserved a Cybertruck are more than Tesla thinks it can handle in the foreseeable future.
Tesla’s Cybertruck landing page now shows a countdown timer to tomorrow’s big delivery event. There is no longer a way to bank a reservation for the Cybertruck, which means that, at least for now, reserving a Cybertruck is not possible.
Prior to removing the option to reserve a Cybertruck, Tesla briefly updated the page to show a $250 reservation fee, which is higher than the initial $100 reservation fee. The change didn’t last for long though, as Tesla quickly reverted back to the $100 amount.
