Rivian has filed a lawsuit in the U.S. Court of International Trade seeking a full refund of tariffs paid under the Trump administration, arguing the taxes were later deemed unconstitutional by the Supreme Court. The company says the refunds could total tens of millions of dollars, funds that would bolster its cash position as it accelerates the mass rollout of the R2 and continues heavy investment in autonomous technology. Rivian’s CFO previously indicated a potential refund in the tens of millions, and the suit aims to secure the exact amount and timing amid a complex federal refunds process. The U.S. Customs and Border Protection notes substantial refunds are being processed—over $121 billion in potential and certified refunds—but industry observers say administrative frictions can delay payouts to importers. The lawsuit comes as Rivian has recently raised about $1.3 billion to strengthen its balance sheet while forecasting profitability possibly by 2028 as it scales production. This legal move reflects a broader wave of companies pursuing refunds related to tariffs after the Supreme Court ruling, highlighting ongoing financial and operational pressures as Rivian scales the R2 ramp-up.
