Crusoe Raises $3.9B to Control the AI Stack From Electrons to Tokens
Crusoe began with an awkward contradiction. In oil fields, natural gas was being burned because there was nowhere useful for it to go. Elsewhere, computers were consuming more and more electricity. Chase Lochmiller and Cully Cavness wondered what would happen if the computers went to the energy instead. They founded Crusoe in 2018 and began […]
Expanse Raises $5.3M to Turn AI’s Most Expensive Guess Into a Prediction
An AI job can wait weeks for its turn on a cluster, run for hours or days, and then disappear with an out-of-memory error because somebody guessed one number wrong. By then, the loss is larger than GPU time. Code has to be checked again. The workload returns to the queue. A researcher who thought […]
EUCLYD Raises €200M to Solve the Hidden Cost Behind Every AI Token
Every AI answer has a hidden commute. Before a model can produce the next word, enormous amounts of information must move between memory and processors. That movement consumes bandwidth, power and money. As AI shifts from models being trained occasionally to models answering requests millions of times a day, EUCLYD believes that journey is becoming […]
Nvidia in Talks to Invest Up to $10B in Anthropic IPO
Nvidia is reportedly considering an investment of up to $10 billion as an anchor investor in Anthropic’s planned initial public offering. The Claude developer is seeking to raise as much as $100 billion at a valuation near $2 trillion, according to September 11 reporting on confidential discussions. The proposed terms remain under negotiation and could […]
a16z Raises $1.1B Machine Age Fund for AI Hardware and Infrastructure
For most of the software era, money could buy engineers, distribution and time. It could not instantly erase a two-year technical lead. AI infrastructure is beginning to change that equation. More compute, memory, networking and electricity can translate directly into more capability, which means physical capacity is becoming part of the competitive advantage again. Andreessen […]
This Week in Funding: AI Capital Spreads Into Everything Around the Model
AI still commanded the biggest checks this week, but the more interesting pattern appeared underneath them. Capital moved into GPUs, physical AI, healthcare workflows, accounting, robotics, grid storage and quantum software. The model race is increasingly creating investment opportunities in everything models need to become useful. 🤖 AI & AI Infrastructure Alibaba raises HK$80B for […]
OpenAI Cuts GPT-5.6 Sol API Pricing as Frontier AI Enters a Cost Race
OpenAI is making its most capable GPT-5.6 model cheaper at a moment when developers are starting to judge frontier AI on more than intelligence alone. GPT-5.6 Sol will temporarily cost $4 per million input tokens and $20 per million output tokens, reducing the price of running complex reasoning, coding and agentic workloads through OpenAI’s flagship […]
HexSeed Technology Raises £600K for Diamond-Cooled GaN Chips
HexSeed Technology is attacking AI infrastructure from an unusually physical angle: the heat trapped inside the electronics moving power around a data centre. The Scottish startup is developing diamond coatings for gallium nitride, or GaN, power devices, using one of nature’s best thermal conductors to pull heat away from chip hotspots before it limits performance, […]
Callosum Raises $100M to Rethink How AI Uses Compute
Callosum is challenging one of AI infrastructure’s most entrenched assumptions: that better intelligence requires increasingly powerful versions of the same models running across increasingly large fleets of similar chips. The London company is building a different architecture, where complex workloads are broken into smaller tasks and each one is assigned to the model and hardware […]
Relativity Networks Raises $22M to Make AI Fiber Faster
Relativity Networks is building for a problem created by AI’s appetite for power. As data-center campuses grow larger and compute is pushed toward locations where electricity, land and infrastructure are available, the physical distance between machines becomes harder to ignore. The Florida-based company believes one of the answers lies inside the fiber itself: moving light […]
DiscreteStack Raises €800K to Help Europe Own Its AI Stack
DiscreteStack is building for European businesses that want powerful AI without handing control of their data and infrastructure to an external cloud provider. The Sofia-based company lets enterprises deploy open-weight AI models on infrastructure they choose, including their own data centers, private clouds and fully isolated environments where sensitive information never needs to leave the […]
Stripe Reportedly Agrees to Buy OpenRouter in $7B+ AI Infrastructure Deal
OpenRouter has built one of the most valuable positions in AI without building the models themselves. It helps developers choose and route requests across hundreds of models, and Stripe is reportedly willing to pay more than $7 billion for that position. OpenRouter gives developers one interface to access more than 500 models from over 80 […]
