Funding is modest and almost entirely venture ($3.1bn of $3.2bn), striking for a layer every model depends on. The movement is upmarket: commodity labelling still leads (40 companies), but expert data and RL environments for frontier labs (25) are the fastest-emerging cluster, where value shifts from volume to expertise.
