The chip rotation reshaped the robotics tape Friday — simulation-software maker Unity led +5.7% while edge-AI silicon Qualcomm fell 7.6% in the semiconductor selloff.

Unity (U) led the robotics basket, up 5.7% to $28.23, with no discrete same-day catalyst — a continuation of the rotation into AI software that lifted the megacaps, layered on momentum from its early-June Q1 preliminary beat (revenue and adjusted EBITDA both well above guidance). Unity maps to the simulation-software chokepoint: the engine that powers synthetic-data generation and digital-twin training environments for robot perception and policy learning. On a day when capital fled AI hardware for AI software, the basket's purest software-tooling name was the natural beneficiary; PTC (+2.8%) caught the same bid, while Synopsys (−0.1%) was flat.

Qualcomm (QCOM) was the worst quotable name, down 7.6% to $189.39, fully reversing the prior session's edge-AI-driven pop. The catalyst was sector-wide: a New York Times report that OpenAI may push its IPO into 2027 triggered a broad semiconductor selloff that carried the Nasdaq to its fifth straight loss (−0.24% to 25,297.62). QCOM sits on the edge-AI-compute chokepoint — the on-robot inference silicon that runs perception and control — and as the basket's most liquid chip proxy it absorbed the heaviest selling. Teradyne (TER −7.4%, test/automation), STMicroelectronics (STM −4.6%, sensing), Ambarella (AMBA −3.1%) and Lattice (LSCC −3.8%) all fell with it.

The humanoid and automation core held up far better than the silicon. Tesla (TSLA +1.2%), Symbotic (SYM +1.2%), Serve Robotics (SERV +1.9%) and Knightscope (KSCP +3.6%) gained; in Seoul, Hyundai (005380.KS +3.4%, Boston Dynamics' parent) rose in its own session. The drag was concentrated in components exposed to the chip cycle — edge silicon and sensing — plus the rare-earth-magnet inputs to actuators, where MP Materials (MP −3.1%) and USA Rare Earth (USAR −0.9%) eased. NSK's thin US ADR printed a spurious double-digit gain, but its Tokyo line (6471.T) actually fell ~2.9% in Friday's session — the kind of ADR mirage worth ignoring in the linear-motion chokepoint.

The calendar concentrates in late July. Tesla's Q2 (July 22) and any Optimus production color anchor the actuator and humanoid theme; Teradyne (July 28), PTC (July 29) and TE Connectivity (July 29) read the automation and sensing chokepoints. NSK's Q1 FY2026 (Aug 3) and Symbotic's Q3 (Aug 6) follow, with a Tesla Optimus Gen-3 reveal expected over the summer. Further out, ABB's robotics divestiture to SoftBank is guided to close mid-to-late 2026, a structural shift in the platforms-integrators chokepoint.
