Two days, three structural shifts. RoboStrategy (BOT) listed on NASDAQ — retail access to Figure AI and Apptronik in one stock. Sereact Cortex 2.0 hit one billion production pick operations (1 failure per 53,000). Skild AI acquired Fetch Robotics to build Skild Brain — one unified control layer for humanoids, AMRs, arms, and robot dogs. $183M deployed in 48 hours. Unitree G1 now costs $13,500. This article is for engineers and tech leads tracking where the Physical AI stack is consolidating. This week's Physical AI news is worth separating into what's technically significant versus what's financially significant — because this week they're both unusually dense. Financially: Physical AI got a NASDAQ ticker. Technically: a robotic picking brain crossed one billion production operations with a world-model architecture that explains why it doesn't need retraining. Strategically: Skild AI made the most important software consolidation move in warehouse robotics since Amazon acquired Kiva Systems.…
