Microsoft Will Lease 3+ Gigawatts of AI Data Center from SpaceX in 2027

Microsoft has already signed 10GW of AI data center contracts year-to-date for over $300B of total contract value, but those contribute to late-2027 and 2028 capacity, leaving a near-term gap to fill. Semianalysis has calculated the tokenomics of OpenAI and Anthropic at $100 billion per year per gigawatt. Microsoft can also monetize at $100 Billion ... Read more

What Contracted Power Actually Means and What is Available for New Contracts

It is a procurement metric, not a sales metric. There are three separate stacks and the industry deliberately blurs them. CoreWeave’s 3.5 GW contracted power and its $99.4B backlog are two different books. How tightly is the second mapped onto the first. They are very tightly, by design, because layer 3 is the collateral for ... Read more

Semianalysis Agrees With NextBigfuture $300B Per Year for SpaceX by End of 2027

Semianalysis agrees with my analysis of SpaceX getting up to $300 Billion per year by end of 2027. Spot prices are higher. The AI lease rates make sense. Coreweave and Nebius are spreading out fixed premium GPUs annual prices but requiring 5 year lockin. 5 years for $100 billion but not available during the next ... Read more

Terafab Rendered in a Video

Terafab will close the gap between today’s chip production and the future’s demand — a future among the stars. Terafab Texas will be the largest and most valuable building on Earth by far. And it will be stunningly beautiful. pic.twitter.com/4NweOqTL7y — Elon Musk (@elonmusk) August 6, 2026 Sequoia's @shaunmmaguire explains why @elonmusk's Terafab is massively ... Read more

Prime Intellect Recursive Language Model

Recursive Language Models (RLMs) are a general inference paradigm that treats long prompts as part of an external environment and allows the LLM to programmatically examine, decompose, and recursively call itself over snippets of the prompt. RLMs can successfully process inputs more than an order of magnitude beyond model context window limits and, even for ... Read more

Hitting and Breaking Ceilings and the Slope

What a 23% kernel speedup tells us about whether AI can improve itself and how to quantify the gains. In 2025, Google DeepMind’s AlphaEvolve, an AI system that discovers algorithms, found a way to make a FlashAttention kernel run 23% faster. This was a great result but it was not the beginning of a runaway ... Read more

Understanding Different AI Data Center Leasing Prices and Categories

The high $50 Billion per GW lease rates for xAI/SpaceX Colossus and similar premium, immediately available AI clusters are for scarce of ready-to-use, large-scale coherent GPU capacity. Kevin Pathrath’s is wrong about a conspiracy. He is comparing against different types of data center. The $2.7M/MW ($2.7 billion per gigwatt build figure is shell-only and brownfield. ... Read more

Self Improving Harness – Self-improving coding and research agent

Prime Agent is an open-source self-improving coding and research agent (harness) released by Prime Intellect on August 5, 2026. It is built for coding workflows and long-running autonomous tasks. It combines a Recursive Language Model (RLM) runtime with a Continual Harness, emphasizing token efficiency and expressiveness through programmatic tool calling, treating context as a variable, ...
