Allbirds stock soared nearly 600% on Wednesday after announcing it's pivoting from sustainable sneakers to AI infrastructure, then tumbled 30% on Thursday to $12/share as reality set in. The company — which sold its shoe business to American Exchange Group in March for $39 million — is now rebranding as NewBird AI to lease high-performance compute hardware to AI developers facing critical GPU shortages. This is a verified but dramatic market move that mirrors the crypto rebranding bubble of 2017 (Long Island Iced Tea → Long Blockchain), suggesting investor enthusiasm for AI pivots may be outpacing fundamental business viability.
