Leopold Aschenbrenner's hedge fund, weeks removed from a near-death margin-call spiral, is back to writing nine-figure checks — this time into the machines that make the chips. Leopold Aschenbrenner's Situational Awareness has poured $400 million into Source Foundry, a stealth chip-manufacturing startup taking

The AI cost squeeze has reached Europe's biggest software company: SAP has frozen most hiring and travel to pay for AI — and unlike a typical belt-tightening, this one is explicitly pro-AI. SAP, Europe's largest software company, suspended most travel and hiring last month because

Two moves in the last day quietly extended what AI assistants can do at work: OpenAI is pulling presentation-making talent into ChatGPT, and Anthropic's Claude Code sessions just learned to talk to each other. OpenAI has acquired NextSlide, a year-old startup whose AI turns prompts, notes,

The AI buildout just booked the entire memory industry's 2027 output before the year even started — and the consumer PC market will feel the squeeze. Memory, not GPUs, is becoming the binding constraint on AI infrastructure. Samsung, SK hynix, and Micron have sold out their entire 2027 DRAM

OpenAI's first consumer device is a hockey-puck-sized, screenless speaker designed with Jony Ive's LoveFrom studio — a bet that the smart speaker category failed for lack of intelligence, not lack of screens. Bloomberg reports OpenAI's first hardware product is a doughnut-shaped, screenless
