Tesla just told Wall Street it plans to spend more than $25 billion this year. That is triple its historical annual capex. The stock promptly gave back its after-hours gains and went red.

The number dropped during Tesla's Q1 2026 earnings call on Wednesday, when CFO Vaibhav Taneja revised the company's full-year capital expenditure forecast upward from the already aggressive $20 billion guidance issued in January. The prior year's actual spend was $8.5 billion. In 2024, it was $11.3 billion. This is not incremental growth. This is a company betting its balance sheet on a different future.

Where $25 Billion Goes

The money is flowing into four buckets: AI training infrastructure and data centres, the Optimus humanoid robot programme, a new semiconductor research fab in Austin being built on Intel's 14A process, and expansion of robotaxi operations.

On the call, Elon Musk confirmed Tesla's Fremont factory will end production of the Model S and Model X to make room for large-scale Optimus manufacturing. The company said preparations for a dedicated Optimus factory outside its Austin campus will begin in Q2, with a target capacity of one million robots per year.

The Intel partnership is a significant signal. Musk said Tesla plans to use Intel's 14A chip process for its in-house AI silicon. "Intel is excited to partner with us on some of the core manufacturing technologies," Musk said. "We plan to use Intel's 14A process, which is state of the art." Intel's stock rose on the mention.

The Earnings Beneath the Capex Bomb

The actual Q1 numbers were mixed. Earnings per share came in at 41 cents adjusted, beating the 37-cent estimate. Revenue of $22.39 billion missed the $22.64 billion consensus. Auto revenue rose 16% year over year to $16.2 billion, but deliveries were flat at 358,023 vehicles, up just 6% from Q1 2025.

The bright spot was automotive gross margins excluding regulatory credits, which hit 19.2%, the highest of any quarter in 2025. Tesla credited lower material costs and higher average selling prices. There were also one-time benefits related to tariff refunds after the Supreme Court struck down portions of Trump's tariff agenda in February.

Tesla is sitting on $44.7 billion in cash and equivalents. It will need it. Taneja warned investors to expect negative free cash flow for the rest of the year as the spending ramp kicks in.

The Bigger Picture

Musk framed the spending as keeping pace with reality. Amazon has guided $200 billion in 2026 capex across AI, chips, robotics, and satellites. Google is projecting $175 billion to $185 billion. Microsoft, Meta, and Alphabet are collectively guiding between $635 billion and $700 billion in combined capital spending this year. Tesla's $25 billion is significant by its own standards but a fraction of the hyperscaler war chest.

The real question is whether Tesla can execute a transition this aggressive while its core car business faces headwinds from BYD, Xiaomi, and a consumer backlash against Musk's political activities. The stock is down 14% year-to-date, underperforming every megacap peer.

On Optimus, Musk was unusually cagey. When asked about a demo, he said competitors "literally do a frame-by-frame analysis and copy everything we're doing," so he would rather unveil the robot closer to the start of production in "late July, August." He also noted that older Tesla vehicles with Hardware 3 computers will not support unsupervised Full Self-Driving, and the company will offer discounted trade-ins for affected owners.

"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," Taneja said. Investors, for now, are not fully convinced. Tesla is the first trillion-dollar tech company to report Q1 results. Alphabet, Amazon, Meta, and Microsoft follow next Wednesday.
