Nebius delays data centers, cuts revenue forecast

Nebius is facing the harsh reality of scaling AI infrastructure: even with $40 billion in planned spending and massive prepayments from Microsoft and Meta, physical construction delays are derailing timelines. A key New Jersey site is months behind schedule due to regulatory fines and generator issues, forcing a shift in delivery dates to 2027. This isn't just a logistical hiccup; it signals that the 'neocloud' model of financing builds with customer cash is fragile when third-party operators fail. The market reacted swiftly, dropping shares by 17% after Nebius cut its 2026 revenue forecast, proving that hype cannot override concrete capacity.

Nvidia privately confirms chip tracking feasibility

Nvidia has privately assured lawmakers that it can technically implement geotracking for its AI chips, contradicting public industry claims that such measures are infeasible. This admission comes amid a smuggling scandal involving Jensen Huang and Megaspeed, pushing the US government toward mandatory location verification via the Chip Security Act. While current tools like Fleet Intelligence already monitor data center locations, this private confirmation suggests Nvidia possesses the underlying capability to enforce stricter export controls if mandated.

United Airlines blocks AI agents from booking flights

United Airlines is actively blocking third-party AI agents from accessing its booking systems, marking a significant shift in how legacy infrastructure handles autonomous software. The airline cites cybersecurity risks from shared credentials and potential violations of federal aviation rules requiring human check-ins. This move aligns with similar warnings from major banks like Bank of America, signaling that critical industries are drawing hard lines around where human oversight is legally required. It effectively kills the dream of fully autonomous travel booking for now, forcing a re-evaluation of agent integration in regulated sectors.
