1.74 million drivers now count as Tesla’s FSD subscribers, mostly because they paid upfront years ago
Tesla’s latest report reveals that its self-driving software user base has surged, but the definition relies on counting one-time purchases as active subscriptions.

Tesla currently claims 1.74 million active subscribers to its Full Self-Driving software, a figure that represents a 67 percent increase over the same period last year. However, this headline number is not solely composed of monthly payers. According to a footnote in the company's Q3 2026 shareholder letter, the metric follows the specific definition outlined in the 2025 CEO Performance Award. This definition includes both customers who pay a monthly fee and those who purchased the software outright with a single payment.
This accounting method is significant because reaching 10 million active FSD subscriptions is a specific milestone Elon Musk must achieve to unlock a portion of his 2025 compensation package. By counting owners who bought the feature years ago as active subscribers, Tesla’s total includes hundreds of thousands of customers who were originally sold the promise of unsupervised self-driving, a capability the company has not yet fully delivered. The only group excluded from this count is those on free trials.
The shift in how these numbers are tallied became more pronounced after Tesla stopped selling FSD as a one-time purchase on February 14, 2026. Since that date, new customers in the U.S. have been required to pay $99 per month to access the software. However, anyone who paid the upfront cost, which reached as high as $15,000, remains in the active subscription count for as long as their vehicle is operational. Tesla reported 1.28 million users under this same definition in April, meaning the number has grown by 460,000 in just six months, though the company has not specified how many of the current 1.74 million are actually paying the monthly fee.
A similar accounting approach appears in Tesla’s report on cumulative deliveries. The company now claims 10.2 million total deliveries, a figure that includes unsupervised robotaxis placed into commercial operation. This inclusion aligns with the 20 million vehicle milestone also required for the CEO’s pay package. The consistency in these metrics suggests a strategic effort to align operational reporting with the specific triggers for executive compensation.
Tesla also highlighted a 75 percent attach rate for FSD on new deliveries in North America during the third quarter. The company noted this was a nearly 20 percentage point increase from the previous period and suggested that the software is driving demand in markets where it is available. However, the shareholder letter does not define exactly what counts toward this attach rate. It is unclear whether this includes subscriptions started with introductory offers or how many of those initial buyers continue to pay after the first few months.
Musk’s 2025 award is structured in 12 tranches, each requiring a specific market capitalization level and an operational milestone. The operational goals include delivering 20 million vehicles, achieving 10 million active FSD subscriptions, deploying 1 million Optimus robots, and operating 1 million robotaxis. As of June 30, Tesla indicated that only the 20 million delivery target was probable to be met. The award period runs until 2035, providing a long timeline for these goals.
In the third quarter alone, Tesla added 260,000 net FSD subscriptions, marking its best quarter to date. If the company maintains this rate of growth, it would take approximately eight years to reach the 10 million subscriber milestone. Alternatively, if it continues at the pace of the last 12 months, adding roughly 700,000 subscribers annually, the goal would take closer to 12 years to achieve. This timeline is critical for investors and employees tracking the progress of the CEO’s compensation vesting.
The definition of an active subscription is now the primary software metric for Tesla. The board approved this definition, and it directly impacts executive pay. While counting upfront buyers is not inherently incorrect, presenting the combined total as proof of monthly momentum can be misleading. The company has not disclosed the specific number of people paying $99 a month, a detail that would provide clearer insight into the recurring revenue generated by the software.
The 75 percent attach rate remains a notable claim, as a high adoption rate for a monthly product would indicate a strong business model. However, without data on retention rates, it is difficult to assess the long-term viability of this revenue stream. Investors are left to wonder how many North American buyers who started a subscription in the second quarter are still paying today, a metric that would better reflect the true engagement with the service.
For those interested in reducing the cost of operating an electric vehicle, pairing a car with home solar power can significantly lower fueling expenses. With electricity rates rising nearly 10 percent last year and expected to continue climbing, solar energy offers a way to offset these costs. Various lease and power purchase agreement options allow homeowners to start saving immediately without upfront costs, potentially reducing energy bills by 20 to 30 percent compared to traditional methods.
