Tesla's FSD Subscription Count Under Scrutiny

Tesla has announced it now has 1.74 million active Full Self-Driving subscriptions, a 67% increase over the past year. However, a footnote in the company's Q3 2026 shareholder letter reveals that this figure is calculated in a specific way to align with a key corporate incentive: it follows “our 2025 CEO Performance Award” and “includes both upfront payment and monthly subscriptions.”

This method means that customers who purchased the Full Self-Driving software as a one-time payment, even several years ago, are counted in the same total as current monthly subscribers. This is a critical detail because reaching 10 million active subscriptions is one of the milestones Elon Musk must achieve to earn his 2025 pay package. Additionally, hundreds of thousands of these individuals were sold the promise of unsupervised self-driving, a feature Tesla has not yet delivered.

Tesla stopped offering the software as a one-time purchase on February 14, 2026. Since then, new customers in the US can only acquire it through a $99 monthly subscription. However, all customers who paid upfront before this date, at prices that went as high as $15,000, remain in the active subscription count as long as their vehicle is active. The only category excluded from this metric is free trials. As of October 2026, Tesla has not disclosed how many of the 1.74 million individuals are on a recurring monthly payment plan.

The company's cumulative deliveries figure of 10.2 million also uses a similar approach to align with the CEO's pay package. This total includes any unsupervised Robotaxis placed into commercial operation, another milestone required for the 2025 award. The operational goals for that package include reaching 20 million vehicle deliveries, 10 million active FSD subscriptions, 1 million Optimus robots, and 1 million commercial robotaxis.

In addition to the subscription total, Tesla reported that over 75% of new vehicle deliveries in North America included FSD subscriptions during the third quarter of 2026, which it described as “a nearly twenty percentage point sequential increase.” The company stated its belief that “FSD is driving demand in markets where it is available.” However, the shareholder letter does not define this attach rate, specify if it includes subscriptions started with an introductory offer, or detail how many of those customers remain subscribed.

To reach the 10 million active subscription target for the CEO's compensation plan, Tesla would need to sustain its current growth for some time. The company added 260,000 net subscriptions in Q3, its strongest quarter to date. At that rate, it would take approximately eight years to reach the goal. Based on the growth rate over the last 12 months, which averaged about 700,000 per year, the timeline would be closer to 12 years. The award plan itself runs until 2035.

The definition of an active subscription is a central issue. While counting individuals who own the software is not inherently misleading, presenting this combined figure as a measure of momentum is complicated by the fact that the metric was created for the CEO's compensation plan. This is now the primary software metric for Tesla, but the company has not clarified how many of these individuals are current, paying monthly subscribers for a service that remains under human supervision.

The 75% attach rate in North America is another key claim that requires further clarification. For a $99 monthly product, such a high take rate would represent a substantial business. However, to validate this, data on retention is needed to determine how many of the North American buyers who began a subscription in Q2 of 2026 are still paying in October 2026.
