FSD Count: Tesla Touts 1.74M

As Tesla continues to develop autonomous driving technology, the company has announced a significant rise in its Full Self-Driving subscriber base, reporting 1.74 million active units for the third quarter of 2026. This figure represents a 67 percent increase compared to the previous year. However, the company's Q3 2026 shareholder letter contains a footnote clarifying that this count follows the definitions outlined in the 2025 CEO Performance Award, specifically including both upfront payments and monthly subscriptions.

Under this reporting method, customers who purchased the Full Self-Driving package as a one-time transaction, some dating back several years, are counted as active subscribers provided their vehicle remains active. The only users excluded from this metric are those participating in free trials. Tesla ceased offering Full Self-Driving as a one-time purchase on February 14, 2026, shifting all new customers in the United States to a monthly subscription model priced at $99. Prior to that date, the software was available for purchase at prices reaching $15,000.

This specific accounting method is relevant because it aligns with the requirements for Elon Musk's 2025 compensation package. To secure his payout, which runs through 2035, Musk must achieve various operational milestones, including reaching 10 million active Full Self-Driving subscriptions. Additionally, hundreds of thousands of the individuals counted in the current 1.74 million total were sold unsupervised self-driving capabilities that Tesla has not yet delivered.

Tesla has not disclosed how many of the 1.74 million subscribers are currently paying the monthly $99 fee. The company previously reported 1.28 million under this definition in April, and six months later, the number of users paying on a recurring basis remains unverified. The shareholder letter does not clarify whether the reported subscription figures include users who started with introductory offers or how many of those individuals continue to pay after a few months.

The shareholder letter also reports that more than 75 percent of new deliveries in North America included Full Self-Driving subscriptions during Q3, noting a nearly twenty percentage point sequential increase. Tesla attributes this to demand for the software in markets where it is available. However, the company has not defined the specific parameters of this attach rate, leaving unclear whether it includes subscriptions initiated with promotional offers or how many of those buyers remain active after a short period.

In addition to subscription metrics, Tesla reported cumulative deliveries of 10.2 million vehicles. This figure also incorporates specific definitions from the CEO Performance Award, counting any unsupervised Robotaxis placed into commercial operation. This approach aligns with the compensation package's requirement to reach 20 million vehicles delivered. As of June 30, 2026, Tesla identified only the 20 million vehicle delivery milestone as probable to be achieved.

Tesla added 260,000 net subscriptions in the third quarter, which the company identifies as its best quarter to date. At this rate, reaching the 10 million subscription target required by the CEO Performance Award would take approximately eight years. If the current pace of the last 12 months, approximately 700,000 per year, continues, the timeline extends to closer to 12 years.

While counting users who purchased the software outright is factually consistent with those vehicles possessing the software, the presentation of this data as active subscriptions raises questions regarding business momentum. The definition was established to satisfy the metrics for the CEO Performance Award rather than to provide investors with a clear understanding of recurring revenue. Furthermore, many of these users were sold unsupervised driving capabilities that remain unavailable, and the company has not disclosed how many of these users are currently paying $99 a month.

The reported 75 percent attach rate for the third quarter represents a significant figure, but its implications depend on retention data. A 75 percent take rate on a $99 monthly product would indicate a viable business, yet Tesla has not provided details on how many North American buyers who initiated a subscription in the second quarter are still paying in October 2026. The company's reported metrics are tied to the compensation plan, and the board wrote the definitions for that plan.
