Our take
UBTECH reported beginning batch production and delivery of Walker S2 in November 2025 for industrial applications. Tesla’s public AI page provides no consumer ordering path for Optimus, and this catalog has no verified public purchase price for either robot. Walker S2 has stronger documented procurement evidence, but a factory buyer should still obtain a task-specific proposal, deployment schedule and support agreement. A demonstration or a future price target is not a confirmed offer.
