The fight moved down a layer — from "who owns the data platform" to "who owns the physical data capture itself" — and two opposite bets went public this week. Samsara shipped its own single-use Bluetooth tracking labels plus an Agent Studio, owning capture → data → agent end-to-end on one closed network; meanwhile Terminal is scaling a neutral "Plaid for telematics" universal API, and Wialon + Teltonika crossed 1 million connected vehicles on a single vendor-locked hardware↔software stack. That's the real signal: vertical integration (Samsara, Wialon) vs. neutral API access (Terminal) are now racing for the capture layer beneath the agents — and Terminal is the closest anyone has come to daXos's cross-vendor wedge. The neutral-substrate opportunity is validated, but the land grab for who standardizes physical-world data is happening now, not later.
