ARK Ties Tesla’s 2031 Case to a $225 Billion AI Spending Assumption

ARK Invest’s Oct. 19 valuation model puts Tesla shares at about $4,400 in 2031 and assigns roughly 80% of the automaker’s projected enterprise value to robotaxis. The estimate also depends on an assumption that cumulative AI infrastructure spending reaches about $225 billion by the end of 2031. That is a modeling input, not a Tesla spending commitment. ARK’s model starts from about $7 billion in cumulative AI infrastructure spending as of December 2025. Separate Terafab figures include a first phase valued at more than $16.8 billion and ARK’s estimate of $3 billion for Tesla’s initial research arm.
