1.74 Million: The FSD Number Driving Tesla's Pay Package

Tesla’s latest shareholder letter reveals a software user base that is growing fast, but the numbers rely on a definition that serves a specific financial purpose.

The company now claims 1.74 million active Full Self-Driving subscriptions, a 67% increase from the same period last year. This figure is central to the discussion around Elon Musk’s 2025 performance award, which includes a milestone requiring 10 million active FSD subscriptions. However, a footnote in the Q3 2026 report clarifies that this count aligns with the CEO’s pay package terms, meaning it includes both monthly subscribers and owners who paid for the software upfront.

This counting method has significant implications. Tesla ceased selling FSD as a one-time purchase on February 14, 2026, shifting new customers to a $99 monthly model in the US. Yet, every owner who bought the software before that date, some at prices reaching $15,000, remains in the active count as long as their vehicle is running. Only free trials are excluded from this total. Despite the June report showing 1.28 million users, Tesla has not disclosed how many of the current 1.74 million are actually paying the monthly fee, leaving investors to wonder about the true recurring revenue stream.

The company applies a similar logic to its delivery figures. The cumulative delivery count now stands at 10.2 million, a number that also matches the pay package criteria by including unsupervised robotaxis placed into commercial operation. This approach helps Tesla track progress toward the 20 million vehicle milestone required for the compensation package.

In North America, Tesla reports that over 75% of new deliveries in Q3 included an FSD subscription, marking a nearly twenty-point increase from the previous quarter. The company attributes this to FSD driving demand in available markets. However, the letter does not define whether this attach rate includes introductory offers or how many of those initial buyers continue paying after the first few months. Unlike the active subscription metric, the attach rate does not explicitly exclude free trials, adding another layer of ambiguity to the data.

The road to the 10 million milestone remains long. Musk’s 2025 award consists of 12 tranches, each tied to market cap and operational goals, including 1 million Optimus robots and 1 million robotaxis. As of June 30, Tesla considered only the 20 million delivery milestone probable. In Q3, the company added 260,000 net FSD subscriptions, its best quarter to date. At this pace, reaching 10 million would take roughly eight years. If the company maintains the average growth rate of the last 12 months, the timeline extends to about 12 years, well within the award’s 2035 expiration.

Counting upfront buyers as subscribers is not inherently incorrect, as those vehicles do run the software. The issue lies in presenting this total as evidence of momentum when the definition was crafted for compensation purposes rather than general business analysis. The board approved these metrics, and the CEO’s pay depends on them, yet the company remains silent on the exact number of monthly payers.

The 75% attach rate is the more compelling claim, provided it reflects long-term retention. A high take rate for a $99 monthly service would indicate a robust business model. Investors are now looking for retention data, specifically how many North American buyers who started subscriptions in Q2 are still paying today. Tesla knows this number, and it will likely become a key focus as the company pushes toward its 2035 targets.
