Tesla's $94.8 billion in 2025 revenue came predominantly from vehicle sales. Energy generation, storage, and services contribute a growing but still minority share. The vehicle business is not a software business: margins are constrained by raw materials, manufacturing overhead, and a competitive pricing environment that has structurally changed since 2022.
BYD has surpassed Tesla in global EV unit sales. Chinese manufacturers have deployed vehicles competitive on range, feature sets, and price. In the US, Ford, GM, Hyundai, and Kia have each established EV product lines that compete meaningfully in mid-range segments. The moat Tesla held from roughly 2017 to 2022, based on a genuine head start in battery technology, software, and charging infrastructure, has narrowed.
Tesla's software and services revenue, including Full Self-Driving subscriptions, Supercharger network access, and vehicle service, remains a small fraction of total revenue. The promise of high-margin software layering onto a hardware platform has not materialised at scale in the income statement. This is the central tension: the narrative of what Tesla will become has outrun the reality of what it currently earns.
The energy segment is the cleanest bright spot. Storage deployments have scaled significantly and segment margins have improved. But energy remains too small at current mix to move the consolidated financials in a meaningful direction.
