The company will go negative on free cash flow for the rest of 2026, CFO Vaibhav Taneja confirmed. But Q1 delivered an unexpected $1.4 billion positive free cash flow beat, and Tesla ended the quarter with $44.7 billion in cash. The capex uplift from $20B to $25B is a $5 billion revision to guidance issued just three months ago.
Tesla announced on its Q1 2026 earnings call on 22 April that it is raising its capital expenditure guidance for 2026 to approximately $25 billion, up from the “over $20 billion” figure communicated to investors in January.
The new figure is roughly three times Tesla’s historical annual capex run rate: the company spent $8.5 billion in 2025, $11.3 billion in 2024, and $8.9 billion in 2023.
CFO Vaibhav Taneja confirmed on the call that Tesla expects to run negative free cash flow for the remainder of the year, a reversal from Q1 which delivered an unexpected $1.4 billion in positive free cash flow.
Tesla ended the first quarter with $44.7 billion in cash, cash equivalents, and short-term investments.

Musk outlined the allocation across several categories. The largest is six simultaneous new production lines across vehicles, robots, energy storage, and battery manufacturing, a scope of parallel ramp unprecedented for Tesla.
This covers Cybercab production (the dedicated robotaxi platform), Semi truck manufacturing, and the Houston Gigafactory. A dedicated Optimus manufacturing facility is under construction outside Tesla’s Austin factory.
Musk indicated on the call that large-scale Optimus production would begin in the “late July, August time frame.” The Fremont, California factory, ending production of the Model S and Model X, will shift to Optimus manufacturing at scale.
A portion of the capex is directed at AI compute. Tesla plans to more than double its AI compute capacity in roughly six months. The company is also building a semiconductor research facility, referred to as a “Terafab”, in Austin, Texas, focused on chip design.
Musk framed this as part of Tesla’s need to control its silicon supply chain for AI training and inference. Strengthening the supply chain across batteries, energy, and AI silicon was also cited as a spending category.
Musk framed the capex increase as an unambiguous positive. “With 2026 we’re going to be substantially increasing our investments in the future,” he said.
“So you should expect to see significant, a very significant increase in capital expenditures, but I think well justified for a substantially increased future revenue stream.”
He contextualised it by comparing Tesla’s spend to Amazon’s projected $200 billion and Google’s $175–$185 billion in 2026 capex.
The robotaxi programme has moved beyond Austin. During Q1, Tesla expanded its unsupervised robotaxi service to Dallas and Houston, adding to existing operations in Austin and the San Francisco Bay Area.
Musk described hyper-conservative system behaviour as an intentional safety posture. Tesla has 1.28 million FSD subscribers. Musk also said Optimus would be “probably” made “useful outside of Tesla sometime next year,” meaning 2027.
Tesla shares briefly gained around 4% on the free cash flow beat before erasing gains in after-hours trading as Musk and Taneja detailed the capex plans.
Taneja was direct: “While this may seem like a lot, and we will have the impact of negative free cash flow for the rest of the year, we believe this is the right strategy to position the company for the next era.”
