Tesla dropped its 2026 capital expenditure guidance at $20 billion, Q4 2025 earnings call, exceeding what the company spent in 2024 and 2025 combined. Tesla’s $20 billion budget for 2026 concentrates on CyberCab factories, AI infrastructure, Optimus development, and training compute. Tesla’s $20 billion budget addresses these concerns by building refining capacity and factory infrastructure simultaneously across multiple product categories. This explains why Tesla’s $20 billion budget almost completely ignores traditional passenger cars. Turns out, the future belongs to whoever builds the better brain, and Tesla’s $20 billion budget proves they’re betting everything on exactly that.
