Tesla stock slips in premarket as tech rout deepens and robotaxi rules stay in focus
Tesla shares fell 2.2% to $397.21 in premarket trading Friday, tracking a broader tech selloff as investors reacted to Big Tech’s rising AI spending. Amazon also dropped after disclosing a major increase in AI infrastructure investment for 2026. In Washington, Tesla and Waymo pressed Congress to update self-driving regulations at a Senate hearing, but the policy debate had little immediate market impact.
