1.74 Million: Tesla's New FSD Metric Hinges on Outright Buyers

Tesla now claims 1.74 million active Full Self-Driving subscriptions, a figure that jumps 67% from the same period last year. The company detailed this growth in its Q3 2026 shareholder letter, which serves as the primary document for evaluating the progress of Elon Musk's 2025 CEO Performance Award. This specific metric is not just a marketing statistic; it is a direct component of the compensation package designed to reward the company's leadership based on operational milestones.

The methodology behind this number is the critical detail. A footnote in the letter states that the count follows the definition set in the 2025 CEO Performance Award. This definition includes both upfront payment and monthly subscriptions. Consequently, owners who purchased FSD as a one-time buy, some of them years ago, are currently counted as active subscribers. This approach matters significantly because 10 million active FSD subscriptions is one of the specific milestones Musk must hit to earn his full pay package.

The implications of this counting method extend beyond simple bookkeeping. Hundreds of thousands of these counted FSD subscribers were originally sold the promise of unsupervised self-driving, a feature Tesla has yet to fully deliver. By including upfront buyers in the active subscription pool, the company presents a larger base of users for a service that remains under development for many of its customers.

Tesla stopped selling FSD as a one-time purchase on February 14, 2026. New customers in the US can now only access the software as a subscription, priced at $99 per month. However, every individual who paid upfront before that date, at prices that reached as high as $15,000, remains in the active count as long as their car is active. The only exclusions from this total are free trials. Despite this, Tesla has not disclosed how many of the 1.74 million users actually pay a monthly fee.

This reporting style appears elsewhere in the letter. Tesla’s cumulative deliveries figure, now at 10.2 million, also counts any unsupervised Robotaxis placed into commercial operation. This adjustment aligns with the pay package, which includes a milestone for 20 million vehicles delivered. The consistency suggests a strategic alignment between reported metrics and compensation triggers.

In Q3, Tesla reported that more than 75% of new deliveries in North America included FSD subscriptions. The company described this as a nearly twenty percentage point sequential increase and stated that it believes FSD is driving demand in available markets. This is a substantial figure, yet Tesla does not define the metric precisely. The letter does not clarify if it counts subscriptions started with introductory offers or how many of those buyers continue paying after a few months.

The path to the 10 million milestone remains long. The 2025 award consists of 12 tranches, each requiring a market cap milestone and an operational achievement. Operational targets include 20 million vehicles delivered, 10 million active FSD subscriptions, 1 million Optimus robots, 1 million robotaxis in commercial operation, and specific adjusted EBITDA targets. As of June 30, Tesla considered only the 20 million delivery milestone probable.

Tesla added 260,000 net FSD subscriptions in Q3, marking its best quarter to date. At this pace, reaching 10 million would take about eight years. If the company maintains the pace of the last 12 months, which was roughly 700,000 per year, the timeline extends to approximately 12 years. The award runs until 2035, leaving sufficient time for these targets to be met or missed.

The board wrote the definition, Musk’s compensation depends on it, and the company has not yet clarified how many people are paying the $99 monthly fee. The attach rate is a compelling claim, but the retention data will be the true test of whether this software is becoming a sustainable business line.
