Bull case
▲ upsideQEC is the universally-required missing layer; Riverlane gets paid whichever hardware modality wins. Local Clustering Decoder (Nature Communications Dec 2025) gives 4× qubit reduction for 1M error-free ops. Oak Ridge deployment.
Bear case
▼ downsideHardware vendors (IBM, Google, Quantinuum) are building QEC in-house. Risks being squeezed to a niche of smaller players if leaders go vertical.
