Tesla’s 1.74 Million FSD Subscribers: A Metric Tailored for the CEO

Tesla’s latest shareholder letter reveals a software user base that appears robust on the surface but relies on a definition crafted to benefit the company’s chief executive.

The path to the current figure began in early 2026, when Tesla ceased selling its Full Self-Driving package as a one-time purchase. Since February 14, 2026, new customers have been required to pay a monthly subscription fee of $99 in the United States. However, the company has continued to count every vehicle that purchased the software upfront, some for as much as $15,000, as an active subscription, provided the car remains in use. This counting method was explicitly linked to the 2025 CEO Performance Award in a footnote within the Q3 2026 report, ensuring that historical buyers contribute to the total despite not paying a recurring fee.

As of this year, Tesla reports 1.74 million active FSD subscriptions, a 67% increase from the previous year. While the company added a net 260,000 new subscriptions in the third quarter, its strongest performance to date, it has not disclosed how many of these users are actually paying the monthly rate. This opacity persists even though reaching 10 million active subscriptions is a critical milestone for Elon Musk to earn a portion of his 2025 compensation package. The same logic applies to Tesla’s cumulative delivery count of 10.2 million, which includes unsupervised robotaxis to align with the award’s 20 million vehicle target.

In North America, Tesla claims that over 75% of new deliveries now include FSD, marking a nearly twenty percentage point increase from the prior quarter. The company attributes this surge to FSD driving demand in available markets. Yet, the letter does not clarify whether this attach rate includes introductory offers or how many of those initial subscribers remain after a few months. Unlike the active subscription metric, the attach rate does not explicitly exclude free trials, leaving the long-term retention of these new users ambiguous.

The compensation structure for Musk includes twelve tranches, each tied to specific market capitalization and operational goals. As of June 30, 2026, the board considered only the 20 million delivery milestone probable. The other operational targets, including 10 million FSD subscriptions, 1 million Optimus robots, and 1 million robotaxis, remain distant. At the current pace of adding roughly 700,000 subscriptions annually, Tesla would need approximately twelve years to reach the 10 million mark. If it maintains the recent quarterly growth rate, the timeline shortens to about eight years. The award remains valid until 2035, giving the company time to close these gaps.

Looking ahead, the focus will shift to verifying whether the high attach rate translates into sustained revenue. Investors will likely seek clarity on retention rates, specifically how many North American buyers who started subscriptions in the second quarter are still paying today. Until Tesla provides that breakdown, the 1.74 million figure will remain a complex blend of loyal monthly payers and long-time upfront buyers, all counted under the same umbrella to satisfy the terms of the CEO’s pay package.
