1.74 Million: Tesla’s FSD Count Hits New High Under Specific Pay-Linked Definitions

Tesla has reported 1.74 million active Full Self-Driving subscriptions as of the third quarter of 2026, marking a 67% increase from the same period last year. This figure serves as the headline software metric for the company, but a footnote in the Q3 shareholder letter clarifies that the count is structured to align with the criteria for the 2025 CEO Performance Award. Specifically, the metric aggregates both monthly subscriptions and vehicles purchased with an upfront payment, a definition that significantly expands the total number.

The counting method matters because reaching 10 million active FSD subscriptions is a key operational milestone for Elon Musk to earn his compensation package. Under the current rules, owners who bought the software outright before February 14, 2026, remain in the active count for as long as their vehicle is in service. These upfront prices previously reached $15,000. Since that date, Tesla has stopped selling FSD as a one-time purchase in the U.S., limiting new customers to a $99 monthly subscription. The only vehicles excluded from the 1.74 million figure are those on free trials.

This approach mirrors other metrics in the shareholder letter that are tailored to the executive pay structure. For instance, Tesla’s cumulative delivery count now stands at 10.2 million, a number that includes unsupervised robotaxis placed into commercial operation. This inclusion helps progress toward the 20 million vehicle delivery milestone required for the award. In April, when Tesla reported 1.28 million FSD subscriptions, the methodology was already noted; six months later, the company has not disclosed how many of the 1.74 million users are specifically paying the monthly fee versus those who purchased the software previously.

Tesla also highlighted a 75% attach rate for FSD on new North American deliveries in the third quarter, describing it as a nearly 20 percentage point sequential increase. The company asserts that the software is driving demand in markets where it is available. However, the letter does not define whether this attach rate includes introductory offers or how many of those buyers continue paying after the initial period. Unlike the active subscription metric, the letter does not explicitly state whether the attach rate excludes free trials.

Musk’s 2025 award consists of 12 tranches, each requiring both a market capitalization milestone and an operational achievement. The operational targets include 10 million active FSD subscriptions, 20 million vehicles delivered, 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. The award remains active until 2035.

In the third quarter, Tesla added 260,000 net FSD subscriptions, its strongest quarterly performance to date. If the company maintains this pace, it would take approximately eight years to reach the 10 million threshold. Conversely, if it sustains the average growth rate of the last 12 months, which is roughly 700,000 subscriptions per year, the timeline extends to nearly 12 years. This trajectory is set against a backdrop where hundreds of thousands of the current "subscribers" were originally sold the promise of unsupervised self-driving, a feature Tesla has not yet fully delivered.

The board established the definition for these metrics, and the company’s financial reporting now relies heavily on them to demonstrate momentum. While counting upfront buyers is not inherently incorrect, as those vehicles do possess the software, presenting the combined total as a subscription base raises questions for investors. Tesla knows the exact number of customers paying $99 monthly, but has not yet shared that specific breakdown, leaving the retention of the new monthly cohort as a key point of interest for the coming quarters.
