Tesla Counts 1.74 Million FSD Users Toward Musk’s Pay Milestone

Tesla reported 1.74 million active Full Self-Driving subscriptions in its third-quarter 2026 shareholder letter, a figure that represents a 67% increase from the same period last year. The company clarified the calculation method in a footnote, stating that the metric aligns with the terms of its 2025 CEO Performance Award. This specific definition includes both customers who paid a lump sum and those who pay monthly fees, effectively treating one-time purchasers as active subscribers.

This accounting approach is critical because reaching 10 million active FSD subscriptions is a key operational milestone for Elon Musk to earn his 2025 compensation package. The award consists of 12 tranches, each requiring both a market capitalization target and a specific operational achievement. As of June 30, Tesla indicated that only the 20 million vehicle delivery milestone was probable for vesting. The other targets include 1 million Optimus robots, 1 million commercial robotaxis, and specific adjusted EBITDA goals.

The counting method has remained consistent since Tesla stopped selling FSD as a one-time purchase on February 14, 2026. New customers in the United States now pay a monthly fee of $99. However, owners who purchased the software upfront before that date, often at prices up to $15,000, continue to be included in the active count as long as their vehicles remain active. Free trials are the only category excluded from this total. In April, the company reported 1.28 million under this same definition, and it has not yet disclosed how many of the current 1.74 million are paying monthly.

The letter also highlights a 75% attach rate for FSD in North American deliveries during the third quarter. Tesla described this as a nearly 20 percentage point sequential increase and suggested that the software is driving demand in available markets. The company did not define whether this rate includes introductory offers or how many of those buyers continue paying after the initial period. The active subscription metric excludes free trials, but no such clarification was provided for the attach rate.

Tesla added 260,000 net FSD subscriptions in the third quarter, marking its strongest quarter to date. If the company maintains this pace, it would take approximately eight years to reach the 10 million milestone. Based on the growth rate over the last 12 months, which averaged about 700,000 new subscriptions annually, the timeline would extend to roughly 12 years. The performance award remains valid until 2035.

The same logic applies to Tesla’s cumulative delivery figure, which now stands at 10.2 million. This number includes any unsupervised Robotaxis placed into commercial operation, a calculation that mirrors the 20 million vehicle milestone in the pay package. Critics note that while counting upfront buyers is not inherently incorrect, presenting the total as a measure of subscription momentum may obscure the number of customers actually paying the monthly fee. The board established these definitions, and the CEO’s compensation now hinges on them.

Tesla’s strategy relies heavily on the perception of rapid adoption. The company believes FSD is a key driver of sales, and the high attach rate supports that narrative. However, without transparency on retention rates or the split between monthly and upfront users, investors are left to interpret the growth based on the specific metrics written into the executive compensation plan.
