Tesla’s FSD Count Includes Past Buyers

Tesla now counts 1.74 million active Full Self-Driving subscriptions, a 67% jump from last year. This headline number relies on a specific definition that includes vehicles bought with a one-time fee. The company detailed this method in a footnote within its Q3 2026 shareholder letter. The metric aligns with the criteria for Elon Musk’s 2025 CEO Performance Award. This pay package requires 10 million active FSD subscriptions as a key milestone. Consequently, owners who purchased the software outright years ago are now classified as subscribers.

Tesla stopped selling FSD as a one-time purchase on February 14, 2026. Since then, new customers in the US have only been able to subscribe for $99 monthly. However, anyone who paid upfront before that date remains in the total count as long as their car is active. Prices for the upfront purchase previously reached $15,000. Free trials are the only exclusion from this figure. In April, Tesla reported 1.28 million active subscriptions using this same method. Six months later, the company still has not disclosed how many of the current 1.74 million actually pay a monthly fee.

This counting strategy appears elsewhere in the shareholder letter. Tesla’s cumulative deliveries figure stands at 10.2 million. This total includes unsupervised Robotaxis placed into commercial operation. This inclusion also matches the pay package, which sets a milestone of 20 million vehicles. The board wrote these definitions to align with Musk’s compensation structure. The operational milestones for the award include delivering 20 million vehicles, reaching 10 million FSD subscriptions, and launching 1 million Optimus robots. As of June 30, Tesla considered only the vehicle delivery milestone probable.

The company reported adding 260,000 net FSD subscriptions in the third quarter. This marks its best quarter yet. At this current pace, reaching the 10 million target would take approximately eight years. If Tesla maintains the pace of the last 12 months, adding about 700,000 subscriptions annually, the timeline extends to nearly 12 years. The compensation award runs until 2035. Tesla also claims that more than 75% of new North American deliveries in Q3 included FSD subscriptions. This represents a nearly twenty percentage point increase from the previous quarter.

Tesla states it believes FSD is driving demand in markets where it is available. The 75% attach rate is a significant claim, but the company does not define it precisely. The letter does not clarify if introductory offers count toward this figure. It also does not specify how many of those buyers are still paying after a few months. While the active-subscription metric excludes free trials, Tesla has not stated if the same exclusion applies to the attach rate. This lack of clarity leaves investors without a clear view of monthly retention.

The definition of these metrics was written to fit the compensation plan rather than to explain the business to investors. Counting upfront buyers is not inherently incorrect, as those cars do have the software. However, labeling them as subscriptions presents the total as proof of momentum. The board approved these definitions, and Musk’s pay depends on hitting these targets. The company knows the exact number of monthly payers but has not shared it. For now, the 1.74 million figure remains the primary software metric reported to shareholders.
