Tesla generated $4.70 billion in operating cash flow during Q2, an 85% increase from one year ago. However, capital expenditures climbed 142% to $5.79 billion, dropping free cash flow to negative $1.09 billion.
Tesla is simultaneously funding Cybercab production, Robotaxi expansion, Optimus manufacturing lines, AI compute, battery capacity, semiconductor production, and new energy-storage factories. The company more than doubled its on-site AI compute capacity in Texas during the first half of 2026.
The investment cycle is already affecting margins and cash generation. Tesla’s adjusted EBITDA margin fell from 15.1% to 11.6%, while cash and investments declined by $1.2 billion sequentially to $43.52 billion.
Tesla still has ample liquidity, but the quarter makes the tradeoff clear: the company is sacrificing near-term profitability and free cash flow to fund its autonomy, robotics, and manufacturing ambitions.
