Tesla vs. GM: Only One Automotive Stock Has the Edge in 2026

Quick Read

• Tesla missed Q2 EPS by 40% as free cash flow went negative; GM beat estimates for the fifth straight quarter and raised full-year guidance.

Tesla (NASDAQ: TSLA) and General Motors (NYSE: GM) reported Q2 2026 results within a day of each other. Tesla posted record deliveries of 480,126 vehicles but missed on earnings. GM raised full-year guidance for the second time in 2026 on the back of truck and SUV demand.

Record Deliveries for Tesla, Record Cash for GM

Tesla’s top line looked healthy. Revenue rose 25.5% year over year to $28.24 billion, and Services & Other jumped 50% to $4.58 billion at a record 14% gross margin. Under the surface, though, operating margin collapsed to 1.4% as operating expenses surged 47% on AI infrastructure, R&D, and stock-based comp tied to the 2025 CEO Performance Award.

Non-GAAP EPS came in at $0.33 versus a $0.5367 estimate, a miss of nearly 40%. Free cash flow flipped to negative $1.09 billion. FSD attach rate above 55% of new North American deliveries is a bright spot, but the software story has to carry a very heavy capex load.

GM’s quarter looked steady by comparison. Adjusted EPS of $3.57 topped the $3.1844 estimate, the fifth consecutive beat. North America carried the freight: $39.9 billion in revenue, 8.6% EBIT margin, and adjusted EBIT up 42.7%.

Adjusted auto free cash flow climbed 78% to $5.03 billion. GAAP net income fell 31% because CEO Mary Barra took a $2.28 billion EV strategic realignment charge to right-size battery capacity. That is a rare admission from a legacy automaker, and investors rewarded it.

Growth Bet vs. Cash Machine

Tesla is spending like an AI hyperscaler with a car company attached. Robotaxi is now unsupervised in six US metros including Austin, Dallas, Houston, Miami, Orlando, and Tampa, and Optimus lines are being installed at Fremont.

GM is folding Cruise back into the mothership and running its truck franchise for cash. Tesla shares are down 16.83% year to date. GM is up 69.53% over the past year.

Margins Will Decide the Second Half

I will be watching whether Tesla can hold operating margin above the low single digits while capex runs hot.

The Reddit post “Tesla misses on earnings despite revenue beat” drew 184 upvotes and 91 comments, so retail is already flagging the profitability question. Piper Sandler analyst Alexander Potter lowered the firm’s price target on Tesla to $450 from $500 and keeps an Overweight rating on the shares.

For GM, the tell is whether pricing power on Silverado, Tahoe, and Escalade holds as tariff policy shifts. Prediction markets currently give Tesla only a 16.5% chance of launching robotaxis in California by year end, which tells you the crowd is not extrapolating the Texas rollout.

Where the Numbers Point Right Now

If you want optionality on autonomy, humanoid robots, and AI compute inside a car company, Tesla is still the only pure play, and I understand paying up for it.

On the numbers, GM screens more defensively: a P/E near 29, a raised full-year outlook of $12 to $14 in adjusted EPS, and real buybacks anchor the story. The signal to watch on Tesla is operating margin recovering above 5% and free cash flow turning positive again.
