Tesla (TSLA) shares cratered nearly 15% this week after its latest earnings report exposed a widening gap between soaring investment and sluggish progress in the autonomous driving sector—a tremor that quickly spread to industry suppliers Rivian (RIVN) and Lucid (LCID), whose shares dropped 4.04% and 5.01% respectively.
The electric vehicle giant delivered a mixed quarter. Revenue jumped 26% year-over-year to $28.24 billion, beating most Wall Street forecasts. Yet beneath the top-line strength, cracks were deepening. Gross margin contracted from 19.2% in the prior quarter to 16.3%, pressured by weakening pricing power and one-time charges. Adjusted earnings per share came in at $0.33, well short of the roughly $0.50 analysts had expected.
More alarming to investors was the capital spending trajectory. Capital expenditures surged 142% year-over-year to $5.8 billion, with full-year spending confirmed to exceed $25 billion, channeled heavily into AI computing, robotics, and chip manufacturing infrastructure. The spending binge pushed free cash flow into negative territory at minus $1.09 billion for the quarter.
But the true trigger for the sell-off lay elsewhere: the growing mismatch between massive capital deployment and the pace of robotaxi commercialization. Elon Musk had previously sketched a vision of “hyper-exponential growth” for the robotaxi fleet. This quarter, however, his tone shifted markedly cautious, warning of a slower-than-anticipated rollout. When pressed by analysts on why the fleet remains stuck “in the dozens” rather than the “hundreds” earlier guidance had implied, management offered little to restore confidence. The market’s message was clear—investors are no longer willing to bankroll soaring expenditures without concrete traction in growth ventures like robotaxis.
The sell-off in Tesla rippled swiftly into Rivian and Lucid. While neither competes directly with Tesla as a robotaxi operator, both are positioned as critical vehicle suppliers to the emerging autonomous mobility ecosystem. Some estimates peg the global robotaxi market at $5 trillion to $10 trillion over the long term. Tesla’s vertically integrated model allows it to manufacture vehicles and develop fleet-operating software under one roof; Rivian and Lucid, by contrast, are playing the supplier role for ride-hailing platforms building out their own autonomous fleets.
That role is already backed by hard commitments. Earlier this year, Uber struck a $1.25 billion deal with Rivian for up to 50,000 R2 SUVs, alongside a $500 million agreement with Lucid for 35,000 vehicles. These orders underscore how lucrative the robotaxi end market could become for both automakers when operators scale up.
Yet Tesla’s scaling struggles may signal broader industry headwinds. If even the most vertically integrated player in the space cannot rapidly push its fleet from dozens to hundreds of vehicles, ride-hailing platforms reliant on third-party suppliers could face similar bottlenecks in procurement and deployment. For Rivian and Lucid, that means the order books from partners like Uber, however promising, may convert into delivered revenue at a slower cadence than previously envisioned.
The takeaway for investors is one of tempered expectations. The long-term thesis for robotaxis as a multi-trillion-dollar market remains intact, and Rivian and Lucid retain meaningful growth catalysts beyond autonomous mobility. But with Tesla’s experience as a leading indicator, the next one to two years may deliver less momentum on the robotaxi supply chain front than the industry had priced in. Patience will be required before those fleet orders truly begin to pay off.
