ARK Invest’s updated open-source model puts Tesla’s expected share price at about $4,400 in 2031, according to ARK’s October 19, 2026 report — a central figure in coverage of cathie wood tesla valuation 2031.
The ARK report, written by Tasha Keeney and Daniel Maguire, gives a base-case $4,400 per share, with a bull case near $5,000 and a bear case around $3,300, using a Monte Carlo simulation across 32 inputs. The ARK team says robotaxi operations will account for roughly 80% of Tesla’s enterprise value in 2031.
ARK’s model lays out specific 2031 outputs: about 10.2 million cars sold in the base case, roughly $1.45 trillion in revenue, and a market-capitalization base-case near $17.5 trillion, which is how the $4,400-per-share figure is derived.
The report says ARK reduced robotaxis’ contribution from ~90% in their 2029 model to ~80% in 2031 because they expect Optimus humanoid-robot services (RaaS) to contribute meaningfully by then. ARK projects Optimus external sales could reach about 1 million units and generate roughly $212 billion in revenue in 2031.
ARK also explains key assumptions behind the cathie wood tesla valuation 2031 update: a continued ramp of vehicle production, steep increases in deployed storage (over 2,200 GWh in the base case), and massive AI/compute spending that ARK models rising toward roughly $225 billion of infrastructure investment by 2031.
How the model hinges on robotaxis and Optimus
In ARK’s base case, the firm assumes Tesla deploys about 8.1 million robotaxi vehicles cumulatively by 2031 and that robotaxi ride-hail net revenue reaches about $753 billion. Their scenario analysis shows the valuation is highly sensitive to robotaxi pricing, utilization and regulatory rollout.
ARK notes risks and limits plainly: slower-than-expected robotaxi scaling, regulatory delays, or other shocks would reduce the outputs. The analysts also flag a SpaceX–Tesla cooperation on “Terafab” compute capacity as a model input, noting a potential joint capital program to relieve chip constraints.
Market coverage of the update emphasizes how far ARK’s 2031 base target sits above current prices and prior ARK targets. Fortune’s June 2024 reporting is an early example of ARK’s robo-taxi-weighted forecasts and quoted ARK saying nearly 90% of enterprise value came from robo-taxis in an earlier model.
For readers tracking the wider picture, note recent site coverage on Tesla’s share price context and related corporate speculation: Tesla stock near $377 on Sept. 22 and commentary about a potential corporate tie-up in Elon Musk hints at Tesla–SpaceX merger.
