Tesla Software Metrics: The 1.74 Million FSD Count

Tesla has reported 1.74 million active subscriptions for its Full Self-Driving software, a figure that marks a 67% year-over-year increase. This specific count is central to the company's recent financial disclosures and directly corresponds to a key operational milestone in the 2025 performance award for CEO Elon Musk.

The definition of an active subscription is detailed in a footnote within Tesla's Q3 2026 shareholder letter. The metric follows the criteria outlined in the CEO's performance award, meaning it includes both customers who pay a monthly fee and those who purchased the software upfront. Consequently, owners who bought the software years ago, at prices that reached $15,000, are included in this total as long as their vehicles remain active.

Tesla ceased selling Full Self-Driving as a one-time purchase on February 14, 2026. Since that date, new customers in the United States have only been able to access the feature through a subscription model priced at $99 per month. The only vehicles excluded from the 1.74 million count are those in free trials. However, the company has not yet disclosed how many of the 1.74 million active users are currently paying the monthly fee versus those who retained the software from a prior purchase.

This counting method is not unique to the software metric. Tesla's cumulative delivery figure, now standing at 10.2 million, also counts unsupervised Robotaxis placed into commercial operation. This approach aligns with the pay package, which includes a milestone of 20 million vehicles delivered. The consistent use of these definitions across different metrics suggests a strategic alignment between reported business data and executive compensation triggers.

In the same letter, Tesla stated that more than 75% of new deliveries in North America included Full Self-Driving subscriptions during Q3. The company described this as a nearly twenty-percentage-point sequential increase and suggested that the software is driving demand in markets where it is available. While significant, the letter does not define whether this attach rate includes customers who started subscriptions with introductory offers or how many of those customers continue paying after the initial period.

The road to the 10 million active subscription milestone required for Musk's pay package remains lengthy. The 2025 award consists of 12 tranches, each requiring both a market cap milestone and an operational achievement. As of June 30, Tesla considered only the 20 million delivery target probable. Other operational milestones include 1 million Optimus robots, 1 million robotaxis in commercial operation, and specific adjusted EBITDA targets. The award runs through 2035.

Tesla added 260,000 net FSD subscriptions in Q3, its highest quarterly gain to date. At this current pace, it would take approximately eight years to reach the 10 million target. If the company maintains the average pace of the last 12 months, adding roughly 700,000 subscriptions annually, the timeline extends to about 12 years. This trajectory highlights the scale of the operational challenge relative to the compensation structure.

The inclusion of upfront buyers in the subscription count has drawn attention because hundreds of thousands of these customers were originally sold unsupervised self-driving capabilities, a feature Tesla has yet to fully deliver. While counting these vehicles is not inherently incorrect, presenting the combined total as a measure of subscription momentum may obscure the distinction between recurring revenue and one-time sales. The board approved this definition, and it now serves as a primary software metric for the company.

Investors and analysts are now focused on retention rates to understand the true business value of the software. A 75% attach rate on a $99 monthly product would represent a substantial revenue stream if customers remain subscribed. However, without clarity on how many buyers from previous quarters are still paying, the long-term financial impact remains difficult to assess. The company has not provided a breakdown of monthly payers versus legacy owners, leaving the composition of the 1.74 million figure ambiguous.
