Elon Musk says Tesla (TSLA) and SpaceX could grow faster than Wall Street expects over the next five years. His comment followed a post by financial journalist Jon Erlichman comparing revenue growth forecasts for major technology companies. The claim has drawn attention from investors watching Tesla stock and SpaceX after strong recent revenue figures.
Analysts cited in the post expect SpaceX revenue to rise 2,090% over five years. Tesla revenue is projected to grow 119%. Musk said both companies could exceed those estimates, placing fresh focus on their spending plans, product growth, and ability to meet aggressive targets.
Tesla reported $28.24 billion in second-quarter 2026 revenue, up 26% from a year earlier. Vehicle deliveries reached record levels, while adoption of Full Self-Driving subscriptions also increased in North America. More than 55% of new regional deliveries included FSD subscriptions.
Tesla stock still faced pressure after the report. Capital spending rose 142%, while free cash flow turned negative for the first time in two years. Musk described 2026 as a major investment year as Tesla funds AI, autonomy, and production expansion.
SpaceX reported $7.8 billion in second-quarter revenue, up 92% from the same period last year. The result beat Wall Street’s $6.9 billion estimate. Starlink revenue reached $4.29 billion, rising 66% year over year.
Musk also told employees that SpaceX’s AI computing revenue could become its largest revenue source soon. During the company’s first public earnings call, he moved his $1 trillion annual revenue target forward to 2030 and said 2029 remained possible.
Musk has often set ambitious schedules for Tesla and SpaceX projects. Several targets, including full self-driving, robotaxis, Cybertruck production, the next-generation Roadster, and Mars missions, arrived later than first announced or remain unfinished.
Tesla’s robotaxi expansion shows the gap between approval and deployment. Nevada recently approved permits that allow up to 5,000 Tesla autonomous vehicles over 12 months. Tesla currently operates only a small unsupervised fleet across its U.S. markets.
Investors are also tracking the cost of growth. SpaceX spent $18.4 billion on capital projects during the quarter, while its AI business remained loss-making despite fast revenue growth. The company’s shares fell after earnings as investors weighed spending against future returns.
For Tesla stock, the next test will be whether higher spending leads to stronger cash flow and faster commercial growth. Musk’s forecast sets a high target, but future results will depend on revenue expansion, project delivery, and execution across both companies.
