TSLA delivered a record 480,126 vehicles in the second quarter of 2026, but operating income fell 57% as higher SG&A and R&D spending, lower vehicle pricing and fading regulatory credit revenue cut into profit. For investors, the quarter showed that unit growth alone is not carrying earnings the way it did before.
Tesla's 480,126 deliveries
480,126 vehicles marked Tesla's highest quarterly delivery total, yet the company still missed expectations in the second quarter of 2026. The gap came as the business kept pushing volume while the profit mix worsened, with lower vehicle pricing weighing on automotive gross margins.
13.5 GWh of storage deployments gave Energy Generation and Storage another lift, with revenue reaching $3.14 billion. Tesla's energy business still adds scale, but the company said its energy margins remain volatile, which makes that growth less predictable than vehicle deliveries.
GM's 8.6% margin
8.6% was General Motors North America EBIT-adjusted margin in the second quarter, and that helped GM beat earnings estimates. GM has kept incentives below industry averages for more than three years, which has let it defend profitability without leaning on heavy discounting.
More than three years of pricing discipline left GM with a cleaner margin profile than TSLA in the quarter. For shareholders comparing the two stocks, the spread is simple: GM is still converting pricing discipline into earnings, while Tesla is spending through a record delivery base.
Robotaxi and $25 billion
Seven U.S. metros now have Tesla's robotaxi service live, while unsupervised operations are ramping in Austin, Dallas, Houston, Miami, Orlando and Tampa. Tesla also reported more than 380,000 unsupervised Robotaxi miles across six cities with no notable incidents, and Cybercab production has begun while Optimus manufacturing lines have been installed.
$25 billion is Tesla's expected 2026 capital spending, and free cash flow turned negative in the second quarter of 2026. That mix leaves the next read-through on whether robotaxi, Cybercab and Optimus execution can justify the spending load as vehicle pricing and regulatory credit revenue keep pressure on margins.
