What changed in 2026
Tesla's stock has underperformed sharply in 2026, falling almost 24% year-to-date while the S&P 500 has risen close to 13.8%. The slide has knocked Tesla's market capitalization to roughly $1.3 trillion, with the share price recovering modestly to $351.12 on the day. The underperformance is driven by a realignment of expectations throughout the year: robotaxi revenue expectations have been pushed out, capital expenditure expectations pushed up, and near-term margin expectations pushed down.
Wall Street's revised forecasts
Analyst consensus compiled by Visible Alpha shows estimates moving in Tesla's disfavor across the 2026-2028 horizon. Net income projections have been cut to $3.5 billion for 2026 from $4.4 billion three months earlier, to $4.5 billion for 2027 from $6.1 billion, and to $7.1 billion for 2028 from $8.9 billion. Capital expenditure forecasts have climbed to $25.2 billion in 2026, $25.7 billion in 2027, and $26.3 billion in 2028, while free cash flow estimates have deteriorated to negative $8.5 billion in 2026, negative $11.1 billion in 2027, and negative $7.8 billion in 2028.
Why the bears see Tesla differently
The bears who doubted that Tesla's robotaxi rollout would meet CEO Elon Musk's timeline have so far been proved right. CFO Vaibhav Taneja indicated on the last earnings call that capital spending will rise to above $25 billion in 2026 and continue to "grow for the next two or three years" to fund Optimus production, the robotaxi fleet, investments in Terafab, solar manufacturing, AI compute, and other automotive manufacturing expansions. Second-quarter margin compression has largely stemmed from an unfavorable sales mix and rising costs.
Where the bears may be wrong
Despite the reset, progress in robotaxi development could still shift Tesla's narrative in a positive direction, particularly because expectations have now been reset lower. Separately, autonomous trucking appears to be reaching an inflection point: Einride AB plans to deploy 500 Tesla Semi trucks this year, a development that could accelerate Tesla Semi sales. Tesla Semi volumes have struggled since the truck was announced in 2017, even as the global freight trucking market is currently valued at $2.2 trillion and faces high diesel and labor costs.
What remains uncertain
It is unclear how quickly the robotaxi rollout and Optimus production can translate into the revenue and margin recovery implied by the bull case. The trajectory of capital spending beyond 2028, and whether free cash flow returns to positive territory on the current schedule, also remain open questions for analysts and investors.
