Symbotic
It's probably the best pure play warehouse automation stock. The only other real competitor is Amazon's internal division working on the same thing.
However, Amazon is likely to keep their tech in-house and not license it out, so SYM is the play.
Walmart owned I believe a 40% stake in the company, and then they went and increased their stake to 60%. So, either Walmart's internal Aquisition team is regarded, or OP just needs to be patient.
