Tesla Counts One-Time FSD Buyers in New Subscription Total

Tesla announced this week that it has reached 1.74 million active Full Self-Driving subscriptions. The company reported this figure in its Q3 2026 shareholder letter. This number represents a 67% increase from the same period last year. The growth marks the best quarter for this metric in the company's history.

However, the definition of the metric is specific. A footnote in the report states that the count follows the terms of the 2025 CEO Performance Award. It includes both upfront payments and monthly subscriptions. This means owners who bought the software outright years ago still count as active subscribers. Tesla stopped selling FSD as a one-time purchase on February 14, 2026. New customers now pay $99 a month in the US. But those who paid up to $15,000 previously remain in the total as long as their cars are active. Free trials are the only exclusion.

This counting method matters for two main reasons. First, hitting 10 million active FSD subscriptions is a key milestone for Elon Musk. He must achieve this to earn parts of his 2025 pay package. Second, hundreds of thousands of these counted users were sold the promise of unsupervised self-driving. Tesla has yet to deliver that feature to the general public. The company does not specify how many of the 1.74 million users actually pay a monthly fee. This silence has persisted since the company reported 1.28 million users in April.

Tesla also reported that more than 75% of new deliveries in North America included FSD in Q3. The letter describes this as a nearly twenty percentage point sequential increase. The company believes FSD is driving demand in available markets. Yet the report does not define exactly how this attach rate is calculated. It is unclear if introductory offers at delivery are included. It also does not say how many of those buyers are still paying after a few months.

The broader context of Musk's compensation includes 12 tranches. Each requires a market cap milestone and an operational one. The operational list includes 20 million vehicles delivered, 10 million FSD subscriptions, and 1 million Optimus robots. As of June 30, Tesla considered only the 20 million vehicle delivery goal probable. The company added 260,000 net FSD subscriptions in Q3. At that pace, it would take about eight years to reach 10 million. At the average pace of the last 12 months, it would take closer to 12 years. The award runs until 2035.

The board wrote the definition for this metric. Musk's compensation depends on it. The company knows the exact number of monthly payers but has not shared it. The 75% attach rate is an interesting claim if it holds up. A high take rate for a $99-a-month product would indicate strong business health. Investors are now waiting to see retention data. They want to know how many North American buyers from earlier quarters are still paying today.

This metric is now the headline software figure for Tesla. The definition was crafted to match the CEO's pay package rather than to give investors a clear view of the business. While counting one-time buyers is not wrong on its own, the labeling creates questions. Many of these subscribers are using a supervised service. They were originally promised unsupervised driving. The gap between the promise and the current product remains a point of discussion among stakeholders.
