Tesla profitability worsens, merger with SpaceX more likely

Tesla has dropped its 2026 mass-production plans for the Cybercab, Tesla Semi and Megapack 3 and removed wording on Optimus mass production from its second-quarter shareholder letter. It said it is pushing to expand battery production, especially 4680 cells, to mass-produce the Cybercab and Semi. Second-quarter revenue rose to $28.2 billion but profitability worsened, and robotaxi service growth also appeared to stall. Elon Musk raised the possibility of a Tesla-SpaceX merger.
