Tesla’s stock surrendered its post-launch gains on Friday as a federal audit into the Cybercab’s self-certification process raised fresh questions about the vehicle’s regulatory path. Shares of Tesla, Inc. (NASDAQ: TSLA) fell 6.50% to $351.90, erasing the 5.42% advance from Thursday’s Cybercab unveiling. The decline wiped out roughly $97 billion in market value, leaving the company with a valuation of about $1.39 trillion.
The sell-off followed news that the National Highway Traffic Safety Administration (NHTSA) had opened an audit query (AQ26002) into Tesla’s decision to self-certify the Cybercab under federal safety standards. The vehicle, which lacks a steering wheel, pedals, and mirrors, was certified by Tesla under standards it deemed applicable. NHTSA is now scrutinizing the technical rationale behind that decision.
The audit population is estimated at around 1,000 vehicles, according to Reuters, a figure that stands in stark contrast to Tesla’s disclosed installed manufacturing capacity of more than 125,000 Cybercabs annually at its Texas plant. Texas records show only 45 Cybercabs registered as of Friday morning, highlighting the gap between production capability and actual deployment.
“These three numbers — registrations, audit population, and installed capacity — are not directly comparable,” said a note from analysts at Morgan Stanley. “They reveal nothing about inventory but expose the central challenge: certification may set the pace for commercial scale.”
The Cybercab launch began Thursday with a small fleet in Austin, but the regulatory overhang is significant. NHTSA’s exemption process, which allows vehicles outside existing standards, limits deployments to 2,500 vehicles per year. Tesla has not applied for an exemption, and the regulator previously said no application was pending. Amazon’s Zoox, which initially attempted self-certification, withdrew that claim during an audit and later received a limited exemption in July 2026.
Legal experts warn of potential litigation. Three former senior NHTSA officials told Reuters that a certification clash could end up in court. Carnegie Mellon professor Philip Koopman noted Tesla’s history of “testing limits and pushing boundaries on regulations.”
The market’s reaction suggests investors are repricing the timeline for Cybercab’s commercial success. Tesla’s second-quarter revenue reached $28.24 billion, but operating margin was a thin 1.4%, and free cash flow was negative at $1.09 billion after capital spending. The Cybercab is central to Tesla’s long-term valuation, with analysts divided on its prospects.
Wall Street targets range from $24.86 (GLJ Research, Sell) to $475 (StoneX, Buy). Morgan Stanley’s Andrew Percoco, who holds a $400 target, warned that limited deployment could trigger selling. GLJ’s Gordon Johnson reiterated his bearish stance, citing the small fleet and lack of rollout details.
The next steps from NHTSA will be crucial. A favorable resolution could clear the overhang, while an adverse finding or a forced exemption application could delay the ramp and add compliance costs. Friday’s sharp reversal indicates that time has entered the Cybercab discount, and investors are now focused on regulatory clarity rather than launch hype.
