Tesla’s FSD Count Hikes to 1.74 Million via Unusual Metric

Tesla reported 1.74 million active Full Self-Driving subscriptions in its third-quarter shareholder letter. This figure represents a 67 percent jump from the same period last year. The company highlights this growth as a key indicator of software momentum. However, the definition behind the number is specific. It aligns directly with the performance award granted to CEO Elon Musk in 2025.

The metric includes both upfront purchases and monthly plans. This means owners who bought the software years ago at prices up to $15,000 still count as subscribers. Tesla stopped selling the package as a one-time purchase on February 14, 2026. New customers now pay $99 a month in the US. Yet, anyone who paid before that date remains in the total as long as their car is active. Free trials are the only exclusion from this count.

This counting method matters for two reasons. First, reaching 10 million active subscriptions is a milestone required for Musk to earn his full pay package. Second, many of these counted users were sold the promise of unsupervised self-driving. Tesla has not yet delivered that level of autonomy. As of June 30, the company considered only the 20 million vehicle delivery milestone probable. It has not yet classified the 10 million subscription target as likely to be met.

Tesla also claims that over 75 percent of new North American deliveries included FSD subscriptions in Q3. The letter describes this as a nearly twenty percentage point increase from the previous quarter. The company suggests the software is driving demand in available markets. However, the letter does not define exactly how this attach rate is calculated. It is unclear if introductory offers count or if buyers retain the subscription after the initial period.

The company added 260,000 net subscriptions in Q3, its best quarter to date. At that pace, reaching 10 million would take about eight years. Based on the last 12 months, the timeline extends to roughly 12 years. Musk’s award runs until 2035 and includes other goals like 1 million Optimus robots. The board wrote the definitions for these metrics, and the company has not disclosed how many of the 1.74 million users currently pay monthly.

Tesla’s cumulative deliveries now stand at 10.2 million. This figure also counts unsupervised Robotaxis in commercial operation to match the pay package targets. The 75 percent attach rate is a significant claim for a $99 monthly product. If it holds up, it signals a strong business model. Investors are watching to see how many Q2 subscribers are still paying today. The clarity of these numbers will define the company’s software valuation in the coming years.
