Rivian Shares Surge 1.49% as Trading Volume Jumps 39% to $640M Ranking 158th Amid CAFE Credit Crisis and $100M Revenue Loss

On August 15, 2025, Rivian (RIVN) saw a 1.49% rise in share price with a trading volume of $640 million, a 39.01% increase from the previous day, ranking 158th among stocks. The surge followed regulatory developments impacting its revenue structure.

Rivian warned of a $100 million revenue loss due to the Trump administration’s revised fuel economy rules, which halted the issuance of compliance letters required to finalize credit sales under the Corporate Average Fuel Economy (CAFE) program. The automaker disclosed that regulatory credits contributed 6.5% of its total revenue in H1 2025, with no further credit sales expected this year. The company has earned over $400 million from such credits since its 2021 IPO but now faces stalled transactions as the National Highway Traffic Safety Administration (NHTSA) reevaluates CAFE standards. A spokesperson for NHTSA stated the agency is “fixing CAFE standards to make cars more affordable again” and will resume compliance letters once the review concludes, though no timeline was provided.

The Zero Emission Transportation Association has petitioned the U.S. Court of Appeals to compel NHTSA to resume compliance letters, but Rivian’s director of public policy noted existing credit deals remain unfinalized. The policy shift, triggered by a July executive action removing penalties for fuel economy violations, has disrupted revenue streams for EV manufacturers reliant on credit trading while benefiting legacy automakers through reduced compliance costs.
