Tesla has entered into an agreement to acquire an undisclosed artificial intelligence hardware company for up to $2.00 billion in common stock and equity awards, according to the company’s 10-Q filing made public on Thursday.
Approximately $1.8 billion of the total acquisition value is subject to service conditions and performance milestones dependent on the successful deployment of the acquired company’s technology, the filing stated.
The agreement was entered into earlier this month with Tesla not disclosing the name of the AI hardware company being acquired.
“In April 2026, the Company entered into an agreement to acquire an AI hardware company for up to $2.00 billion in Tesla common stock and equity awards, of which approximately $1.8 billion is subject to certain service conditions and/or performance milestones dependent on the successful deployment of the company’s technology,” Tesla disclosed.
The acquisition disclosure arrives one day after the company’s Q1 2026 earnings call, on which management outlined a substantially larger 2026 capital spending plan tied to AI infrastructure, robotaxi scale-up, and Optimus production preparations.
Capex Lifted
On the earnings call Wednesday, Tesla raised its 2026 capital expenditure guidance to more than $25 billion, up from the $20 billion figure issued at the Q4 2025 earnings call in January.
The company spent $9 billion on capex in 2025.
The $1.8 billion milestone-linked portion equals approximately 0.12% of Tesla‘s $1.45 trillion market capitalisation, and roughly 7% of the $25 billion 2026 capex budget.
Chief Executive Elon Musk framed the spending increase as justified by the future revenue stream the investments are expected to unlock.
“We are going to be substantially increasing our investment in the future,” Musk told analysts. “You should expect to see very significant increase in capital expenditures that are I think well justified for a substantially increased future revenue stream.”
“Tesla is not alone in this,” Musk added, noting large capex plans at top technology companies.
Amazon has projected about $200 billion of capital expenditures in 2026 across AI, chips, robotics, and low earth orbit satellites, while Google is guiding to between $175 billion and $185 billion, up from $91.4 billion a year earlier.
Chief Financial Officer Vaibhav Taneja confirmed the duration of the investment cycle and its cash flow implications.
“We are in a very big capital-investment phase, which is going to start now and would last a couple of years,” Taneja said on the call, adding that the company will record negative free cash flow for the rest of 2026.
Tesla is in the middle of one of the most expensive bets in its history. Musk has pivoted the automaker’s focus to AI-powered self-driving cabs and humanoid robots, and much of Tesla‘s $1.45 trillion market capitalisation rests on that vision.
The Stock Reaction
Tesla shares traded lower in Thursday’s pre-market session after a post-earnings rally was reversed during Musk’s remarks on the Q1 2026 conference call.
The shares spiked as high as $406.77 in after-hours trading immediately after Tesla posted a non-GAAP earnings-per-share beat of $0.41 against consensus of $0.37, alongside the announcement of the production start of its fully autonomous Cybercab model.
Shares then slid through the earnings call, bottoming at $374.64. Tesla traded at $376.60 in pre-market Thursday, down 2.82% from Wednesday’s $386.42 close.
AI5 Tapeout
Tesla has been ramping its in-house AI chip roadmap.
The company completed its AI5 chip tapeout earlier than scheduled, with teams working six months straight through holidays and weekends, according to management comments on the call.
AI5 is targeted primarily for Optimus and the supercomputer, rather than the vehicle roadmap as previously signalled.
The company has also announced the Terafab chip manufacturing project — a joint venture with SpaceX and xAI announced in March 2026.
The Terafab pilot facility alone is estimated to cost between $20 billion and $25 billion, representing a capital commitment separate from the $25 billion 2026 guidance.
An additional AI hardware acquisition at $2 billion sits on top of that infrastructure, adding a fourth pillar — the acquired company’s technology — to the existing Terafab, AI5, and Dojo programs.
Tesla did not indicate when the acquisition is expected to close or disclose the target’s revenue, headcount, or primary product focus.
