Tesla bulls correctly note that the vehicle business is not the entire story. The Energy Generation and Storage segment, which includes Megapack utility-scale battery storage, has grown significantly and carries higher margins than the vehicle division. Services and Other, which includes Supercharging, insurance, and software, is also a growing contributor.
The challenge is scale. In 2025, the automotive segment still accounts for the overwhelming majority of Tesla's revenue. Energy and Services combined are meaningful but not yet large enough to offset the deterioration in automotive unit economics. For the Energy segment to move the needle at a $1.4 trillion valuation, it would need to grow to tens of billions in high-margin revenue. The trajectory is encouraging, but the timeline to that scale is measured in years.
Full Self-Driving and the promised robotaxi network are the wilder versions of this argument. Tesla has been describing FSD as near-complete and robotaxi as imminent for several years. The autonomous vehicle business could, in theory, be extraordinarily valuable if it achieves wide deployment with strong unit economics. But it has not happened yet, and pricing a $1.4 trillion market cap on a business that does not exist carries its own risk profile.
The practical question is not whether Tesla's non-auto businesses are growing. They are. The question is whether the pace of that growth justifies the current multiple, and whether the automotive margin recovery that those businesses are supposed to subsidize will actually materialize.
