ARK Invest Recap: Tesla's Updated 2031 Valuation, Robotaxi, Optimus and a Possible SpaceX Merger

The newest full video on ARK Invest's official YouTube channel, "Our Updated Tesla Valuation, Explained", was published on November 5, 2026 (about 4:00 PM ET) and runs about 15 minutes. ARK's Tasha Keeney and Daniel Maguire walk through the firm's newly published Tesla valuation model. The previous model targeted 2029; this one runs to 2031. They cover what changed on robotaxi and Optimus, a new AI infrastructure line, why full self-driving subscription revenue is left out of the model, and how they think about a possible Tesla and SpaceX merger. The model itself is on ark-invest.com.

Key takeaways

• The model horizon moved from 2029 to 2031. Keeney and Maguire say ARK published its long-awaited update on the ark-invest site; readers had been waiting since the prior 2029 valuation.
• Robotaxi is still the main value driver, but less dominant. They put robotaxi at roughly 80% of Tesla's enterprise value in 2031, down from about 90% in the prior model, because Optimus is assumed to scale more than before.
• Optimus base case is about 1 million units by 2031. Maguire says the base case assumes roughly 1 million Optimus robots deployed by 2031 earning robot-as-a-service revenue at software-as-a-service-like margins. They call that conservative next to Elon Musk's public comments about 100 million or 1 billion units in the same year.
• A new AI infrastructure line is in the model. Maguire estimates Tesla could cumulatively spend on average about $225 billion by 2031 across chips, the Terafab initiative and related items, up from roughly $7 billion at the end of last year. In their framing, more spend feeds more Optimus capability.
• Robotaxi pricing was updated from willingness-to-pay research. Keeney cites an average ride-hail price of $2.80 per mile today and says autonomous ride-hail can undercut at scale; the model assumes no surge pricing, which they describe as conservative.
• FSD subscription revenue is excluded from the model. Maguire says ARK leaves it out because it sees the robotaxi opportunity as much larger. On the latest earnings call, they note roughly 75% of North American deliveries attached a full self-driving subscription (about a 20-point improvement quarter over quarter), and Pierre Ferragu's estimate of annual recurring revenue approaching $1 billion was confirmed.
• They discuss a Tesla–SpaceX merger separately from the standalone model. Points they raise include Terafab/chips, management bandwidth, SpaceX AI models as an Optimus orchestration layer, a combined ambition of 100 gigawatts of annual solar capacity, Starlink connectivity in Cybercab for media, and robotaxi cash flow that they think could push Tesla's gross margins toward about 70% by 2031. They also relay Elon's caution that a deal is not a certainty and would need more than 50% of Tesla shares to approve it.
• These are opinions and forecasts. The speakers are describing ARK's open model and their reading of earnings calls and public comments. Numbers can change, and they say they have no special information on merger timing or price.

Newsworthy investment insights

These are opinions, forecasts and claims voiced in the video. GNOUP has not independently checked them. Neither ARK's statements nor ours are a recommendation about any security. This video does not state a specific per-share Tesla price target in the transcript or official description we used.

Horizon shift and the robotaxi / Optimus mix (ARK forecasts)

• Keeney opens by saying the majority of Tesla's value ARK believes in the next five years will still come from robotaxi, which was also true in the prior model. Maguire says the last (2029) model had robotaxi at roughly 90% of enterprise value; the move toward about 80% in 2031 reflects larger external Optimus sales in this year's update.
• Maguire's base case: by 2031, roughly 1 million Optimus units deployed on robot-as-a-service economics with software-as-a-service-like margins. He contrasts that with Elon's comments of 100 million or 1 billion for the same year and calls ARK's figure quite conservative. Keeney notes that after the prior publication Elon publicly suggested ARK was too conservative on Optimus; the figures have risen, but nowhere near some of the larger estimates people discuss.

Optimus manufacturing caution and early use cases (claims from earnings / ARK commentary)

• Keeney says recent Tesla earnings commentary has cautioned that Optimus is a hard manufacturing problem, not only a data problem: getting the robot right (including the hands) remains difficult, with upfront near-term challenges. They still expect shipping to customers by the end of next year, which Keeney reads as implying a minimum viable product customers will accept.
• Maguire notes that a manually driven car is much more functional than a manually operated Optimus, so Tesla needs to bootstrap training data. He points to the Optimus Academy discussed on the earnings call—10,000 to 20,000 to 30,000 robots to train—and to hardware work needed before that data gathering really starts. Keeney adds that first applications are expected to be industrial or manufacturing use cases, and that Tesla is well positioned as a vertically integrated player, while stressing the market is still early.

New AI infrastructure line: ~$225 billion cumulative by 2031 (ARK estimate)

• Maguire says that since the prior model two years ago, GPU training and inference have become central, so ARK added an AI infrastructure line. As Tesla spends more on that infrastructure, Optimus capability in the model grows.
• The estimate he cites: by 2031, Tesla could cumulatively spend on average about $225 billion on AI infrastructure (chips, Terafab and related line items), up from roughly $7 billion at the end of last year. He compares the ramp to hyperscaler conversations that have moved from billions toward trillions. Keeney notes the Tesla valuation still values Tesla as a standalone business; merger thoughts are separate.

Robotaxi pricing update (research-based model inputs)

• Keeney says ARK updated robotaxi pricing using willingness-to-pay research across income deciles. The average ride-hail price they cite is $2.80 per mile today. They argue autonomous ride-hail can proliferate because at scale it is cheaper to operate and utilization can be better than human-driven fleets, which expands the market via lower prices—but the business does not have to start at those lower prices, since some metro customers will pay more.
• A conservative choice they highlight: no surge pricing in the model, even though higher-income travelers tend to travel more at peak hours. Keeney frames that as potential upside left on the table, and says the pricing update had a meaningful impact on their price target (without stating a per-share number in this video).

Why FSD subscriptions are left out of the model (modeling choice)

• Maguire says ARK often gets asked about monthly FSD subscriptions and currently does not model that revenue, mainly because of the size of the robotaxi opportunity Keeney described.
• From the latest earnings call (as they recount it): roughly 75% of North American deliveries included an FSD subscription; people are paying ahead of the free month. Keeney says their analysis shows that attach rate improved about 20 points versus the prior quarter and would beat comps such as SiriusXM in-car subscriptions and GM Super Cruise (cheaper products with longer trials). Maguire notes Pierre Ferragu estimated annual recurring revenue approaching $1 billion and that the company confirmed that estimate—potentially meaningful near term, still outside ARK's long-term model.

Possible Tesla–SpaceX merger (opinions, not a certainty)

• Keeney says from ARK's perspective a merger would be beneficial for both companies: Terafab aimed at chip constraints if Optimus volumes approach Elon's estimates; relief on management bandwidth; and SpaceX AI / SI models as an orchestration layer for large-scale Optimus deployments.
• Maguire adds power: SpaceX and Tesla are each aiming for 100 gigawatts of annual solar capacity—roughly five to six times what the U.S. produced last year in their framing. He also notes Cybertrucks rolling out with Starlink connectivity for media in driverless robotaxis.
• On cash flow: Keeney and Maguire say the robotaxi business in their model looks very cash-flow generative and could push Tesla's gross margins toward about 70% by 2031 as the business shifts toward recurring autonomous ride-hail revenue—useful for funding AI ambitions of a combined entity. Maguire likens robotaxi cash generation to "Starlink on steroids."
• Caveats they relay: Elon said on the SpaceX call that a merger is not a certainty; more than 50% of Tesla shares would need to agree. Timing looks near-term within the next five years, likely sooner, but they say they cannot pin a date and have no special information. On price, they have seen street talk of a 30% to 50% premium. The published Tesla valuation measures Tesla standalone, with a separate portion on what a combined entity could look like in 2031. Longer term, Keeney argues SpaceX's AI business growing exponentially could become the majority of revenue and earnings for a combined entity, so the benefit would run both ways.

Lighter / framing notes

• Maguire ends by pointing viewers to ark-invest.com for the Tesla model. The hosts also mention their X handles for updates; GNOUP is not promoting those accounts.
