Tesla builds electric cars in its own factories (including its own battery cells) and sells them directly to consumers with no dealers, then keeps earning recurring money from the same car through FSD software subscriptions, charging, insurance, and service.
How Tesla makes money
Tesla buys raw materials and builds cars — including its own battery cells — in vertically integrated factories, then sells directly to consumers with no dealer network. That's only the first sale: every car keeps generating money afterward through FSD (self-driving) software subscriptions, Supercharger charging, insurance, and service. Separately, Tesla sells regulatory credits to other automakers at close to zero cost, and reuses its automotive battery technology to sell energy storage (Powerwall, Megapack) to homes, businesses, and utilities.

Where the revenue comes from
| Line item | Revenue | Share |
|---|---|---|
| Automotive sales | 65,821 | 69.4% |
| — of which regulatory credits | 1,993 | 2.1% |
| — of which leasing | 1,712 | 1.8% |
| Services & other | 12,530 | 13.2% |
| Energy generation & storage | 12,771 | 13.5% |
| Total revenue | 94,827 | 100% |
Automotive gross margin has fallen three years straight — 19.4% (2023) → 18.4% (2024) → 17.8% (2025) — while energy gross margin has improved, from 26.2% to 29.8% over the same span. Tesla doesn't disclose segment operating income, only gross margin.

Customers and competitors
Almost entirely B2C. Tesla states that no customer accounted for 10% or more of accounts receivable at year-end 2025 or 2024, so customer concentration risk is low. One notable exception: in 2025 Tesla recognized $430 million (0.45% of total revenue) selling Megapack units to xAI, a company where CEO Elon Musk also serves as CEO/director — disclosed as a related-party transaction.
- BYD (China) — vertically integrates low- and mid-priced EVs and batteries; China's largest EV maker and a direct price-competition threat.
- GM and Ford — traditional automakers funding EV lineup expansion with combustion-engine profits, backed by brand strength and existing dealer networks.
- Waymo (Alphabet) — operates robotaxis using lidar-based self-driving, a fundamentally different technical approach from Tesla's camera-only FSD.
Note: Tesla's 10-K doesn't name competitors individually, describing them only as "existing and new automotive manufacturers" (Item 1, "Competition," p.9–10). Source: 10-K FY2025, Note 2 (Concentration of Risk), Note 15 (Related Party Transactions, p.92).
The metric that matters most in this sector
Automotive gross margin shows whether rising deliveries reflect real pricing power or just deeper discounting to move volume.
| 2021 | 2022 | 2023 | 2024 | 2025 |
|---|---|---|---|---|
| 29.3% | 28.5% | 19.4% | 18.4% | 17.8% |
Vehicle deliveries have now fallen two years straight — a 2023 peak of about 1.809 million, then roughly 1.789 million (2024) and 1.64 million (2025) — alongside the shrinking margin, together signaling that the core auto business has entered a plateau-or-decline phase rather than a growth one. Energy storage deployments (GWh), by contrast, have grown sharply: 4.0 (2021) → 6.5 → 14.7 → 31.4 → 46.7 (2025).

Leadership and ownership
CEO Elon Musk — whose formal title is "Technoking of Tesla and Chief Executive Officer" — has led the company since 2008, about 18 years. The 10-K itself discloses, as a risk factor, that Musk splits his attention across SpaceX, xAI, Neuralink, and The Boring Company and doesn't devote himself full-time to Tesla. Insider ownership isn't broken out in the 10-K (2026 proxy statement needed for confirmation); a new 2025 performance award could grant Musk up to 423 million additional shares — roughly 11% of shares currently outstanding — which would meaningfully raise his stake if achieved.

Capital returns
Dividends: none. Tesla states it has never paid a cash dividend and has no plans to. Buybacks: none — FY2025 repurchase activity is disclosed as "None," and the Q2 FY2026 10-Q makes no mention of any repurchase. Shares outstanding are actually rising: 3.216 billion (end 2024) → 3.751 billion (end 2025, +16.6%) → 3.949 billion (June 2026), largely driven by the 2025 CEO performance award. With no dividend or buyback offsetting new share issuance, existing shareholders are being gradually diluted.

How this company could fail
- Shrinking regulatory-credit and EV tax-credit revenue — the 2025 OBBBA law scaled back federal EV tax credits and emissions-credit programs. Regulatory-credit revenue alone fell 28% in 2025, from $2.76B to $1.99B, and this near-zero-cost, pure-profit revenue stream is shrinking.
- Musk key-person risk — the 10-K itself acknowledges heavy reliance on Musk, who "does not devote his full time" to Tesla; it also separately discloses that Musk has pledged Tesla shares as loan collateral at banks, meaning a sharp stock decline could trigger forced sales that deepen the drop further.
- EV demand slowdown and intensifying competition — the 10-K warns that as EVs remain a small share of total vehicle sales, heightened competition could mean "declining sales volume, price cuts, reduced revenue, and loss of customers and market share." This is already materializing: 2025 automotive revenue fell 9% and gross margin dropped to 17.8%.

What we still don't know
- Model-level delivery breakdown (Model 3/Y vs. S/X/Cybertruck) isn't disclosed in table form in the 10-K — quarterly shareholder letters or investor presentations would be needed.
- How much of the 2025 CEO performance award (up to 423 million shares, up to $120B in value) will actually be recognized as an expense depends on probability-of-achievement assessments not fully knowable from this filing alone.
- Exactly how much revenue FSD and robotaxi currently generate isn't quantified separately in the filings — the most recent earnings call is the place to check.
- Insider ownership percentages aren't in this 10-K and require confirmation from the 2026 proxy statement.
