Tesla Semi Production Begins
CEO Elon Musk confirmed during Wednesday’s earnings call that “we have started production with the Tesla semi-truck.” He said the company is simultaneously ramping battery production, lithium refining, cathode manufacturing and future solar manufacturing capacity. The company’s shareholder update stated that the Nevada Tesla Semi factory remains on schedule, with production expected to begin later this year. In the manufacturing section of the report, Tesla listed its Nevada Semi facility as being in the commissioning phase.
CFO Vaibhav Taneja attributed higher operating expenses partly to development costs for the Semi, noting: “The increase came primarily from significant research and development-related activities, including pre-production ramp costs for new products like the semi-truck, Optimus, CyberCab and other AI initiatives.” Tesla also said increased production of its 4680 battery cells is supporting planned production ramps for both the Cybercab and Tesla Semi programs.
Supply Chain Constraints and Supplier Partnerships
Executives said supply chain constraints remain the primary limitation on increasing vehicle production going forward. Taneja said production growth continues to be limited by battery availability and electronic components, but Tesla is working to secure strategic supplier agreements to support future growth. During the analyst Q&A, Musk highlighted supplier investments supporting Tesla’s manufacturing expansion, citing semiconductor production from Samsung and TSMC, battery investments from Panasonic, and memory supply commitments from Micron.
Capital Expenditure Surge
Tesla reported capital expenditures of $5.8 billion in Q2, more than double the previous quarter, as the company expands manufacturing capacity. Management expects capital spending to exceed $25 billion this year and continue increasing over the next several years. Tesla CEO Elon Musk described this as the company’s largest investment cycle, with spending focused on expanding manufacturing capacity across several businesses, including the Tesla Semi program.
Why it matters: Tesla’s continued investment in the Semi program signals growing competition in the Class 8 truck market while highlighting the industry’s broader shift toward domestic manufacturing and electrification.
