Tesla's Q2 2026 earnings showed record revenue of $28.24 billion but a brutal profit miss, with operating income down 57%, free cash flow negative by $1.1 billion, and capex surging 142% as Musk funds AI and robotics bets. The stock dropped roughly 14% on July 23, erasing more than $140 billion in market value, as analysts cut price targets and investors grew impatient for tangible milestones from Optimus and Cybercab.
