Nvidia expanding buybacks to $235B while peers pause repurchases to fund AI capex shows two different phases of the AI trade—chip suppliers harvesting cash while downstream platforms reinvest. If you depend on GPUs, read this as confirmation that supply will stay tight and expensive even as Nvidia optimizes for shareholder returns.

Efficient Computer, which uses dataflow architectures to develop faster and more energy-efficient chips, raised a $97M Series B at a $650M valuation

$97M into dataflow chips is a bet that general-purpose GPUs won't be the only answer for AI and high-throughput workloads — power and efficiency are becoming board-level constraints. If you're planning multi-year AI infra, keep a slot open for non-GPU accelerators and design your stack so you can swap in specialized silicon without a full rewrite.

Sanctioned billion-dollar cybersecurity company from Russia finds 11 vulnerabilities in Google and Apple products — including a nasty one that compromised a device just through a malicious NFC tag

A sanctioned Russian security firm surfacing 11 bugs across Apple and Android—including NFC drive-by compromise—underscores that mobile OS hardening is now part of geopolitical maneuvering. Treat mobile as an active threat surface again: tighten BYOD, patch SLAs, and any workflow that assumes phones are “secure enough” by default.
