Tesla Claims 1.74 Million Self-Driving Subscribers, But Definition Relies on One-Time Buyers

Tesla reported that it currently has 1.74 million active Full Self-Driving subscriptions, a figure that represents a 67% increase from the same period last year. However, a detailed footnote in the company’s third-quarter 2026 shareholder letter reveals that this number is calculated specifically to align with the criteria of Elon Musk’s 2025 CEO Performance Award. The metric includes both customers who pay a monthly fee and those who purchased the software with a one-time upfront payment. This accounting method means that owners who bought the package years ago are still counted as active subscribers, provided their vehicles remain active. This distinction is critical because reaching 10 million active subscriptions is one of the key operational milestones required for Musk to earn his compensation. Furthermore, hundreds of thousands of these counted users originally purchased the software on the promise of unsupervised self-driving capabilities, a feature Tesla has not yet fully delivered.

The shift in how Tesla counts these subscriptions began earlier this year. On February 14, 2026, the company stopped selling Full Self-Driving as a one-time purchase, a product that previously cost up to $15,000. Since that date, new customers in the US have only been able to access the feature through a monthly subscription priced at $99. Despite this change, anyone who paid the upfront fee before February remains in the active subscription count. The only exclusions from this metric are free trials. In April of this year, Tesla reported 1.28 million subscriptions using this same definition. Six months later, the company has not clarified how many of the 1.74 million users are actually paying the monthly fee versus those who paid upfront.

Tesla applied a similar strategic counting method to its delivery numbers. The company’s cumulative delivery figure, which stands at 10.2 million, also includes unsupervised Robotaxis placed into commercial operation. This approach mirrors the 20 million vehicle milestone found in the CEO’s pay package. Additionally, Tesla claims that more than 75% of new deliveries in North America included FSD subscriptions in the third quarter, noting a nearly twenty percentage point increase from the previous quarter. The company stated it believes FSD is driving demand in available markets. However, the letter does not define whether this attach rate includes introductory offers or how many of those buyers continue paying after a few months, unlike the active subscription metric which excludes free trials.

The path to the 10 million subscription milestone is long. Musk’s award consists of 12 tranches, each requiring specific market cap and operational goals, including 20 million vehicles delivered, 1 million Optimus robots, and 1 million robotaxis in commercial operation. As of June 30, Tesla considered only the 20 million delivery milestone probable. In the third quarter, Tesla added 260,000 net FSD subscriptions, its highest quarterly gain to date. At this pace, it would take approximately eight years to reach 10 million. If the company maintains its trailing 12-month average of roughly 700,000 additions per year, the timeline extends to about 12 years. The compensation award remains valid until 2035.

While counting upfront buyers as subscribers is not inherently incorrect, critics note that it presents a specific narrative for investors. The definition was crafted to support the CEO’s compensation structure rather than to provide a clear view of recurring revenue. Tesla has not disclosed the number of customers currently paying $99 monthly, a figure the company undoubtedly knows. The 75% attach rate remains a significant claim, but without data on retention, specifically how many buyers from the second quarter are still paying, the long-term strength of the subscription model remains unclear. The board has established the definition, and Musk’s pay depends on it, leaving investors to weigh the reported growth against the underlying payment behaviors.
