Anthropic Announces SpaceX Colossus Compute Deal and Higher Claude Usage Limits
Anthropic has signed an agreement with SpaceX to access the full compute capacity of the Colossus 1 data center, gaining over 300 megawatts and 220,000+ NVIDIA GPUs within a month. This deal, combined with prior agreements with Amazon, Google/Broadcom, Microsoft/NVIDIA, and Fluidstack, enables Anthropic to double Claude Code rate limits, remove peak-hour restrictions for Pro/Max users, and raise API rate limits for Claude Opus models. The announcement also notes interest in developing orbital AI compute capacity with SpaceX, and outlines international infrastructure expansion for enterprise compliance needs.
Anthropic raises $65B in Series H funding at $965B post-money valuation
Anthropic has closed a $65 billion Series H round led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, valuing the company at $965 billion post-money. The company reports annualized run-rate revenue crossing $47 billion and highlights major compute expansion agreements with Amazon (up to 5 GW), Google/Broadcom (5 GW of TPU capacity), and SpaceX (Colossus GPU access). Strategic infrastructure partners Micron, Samsung, and SK hynix join the round alongside a broad syndicate of institutional investors. Funding is earmarked for safety and interpretability research, compute scaling, and product expansion including Claude Code and Cowork.
Can the stockmarket swallow Anthropic, SpaceX and OpenAI?
The Economist examines whether public markets can absorb the potential IPOs of Anthropic, SpaceX, and OpenAI, three of the largest private companies in their respective sectors. The piece addresses valuation, liquidity, and structural questions around bringing frontier AI labs to public markets. With 368 HN points and 641 comments, the article has generated substantial community discussion. The framing reflects growing investor and analyst attention to the eventual public-market transition of major AI labs.
S&P 500 rules block entry for SpaceX, OpenAI, and Anthropic
The S&P 500 index committee declined to waive profitability requirements for SpaceX, a decision that also effectively bars OpenAI and Anthropic from index inclusion. The ruling reflects the index's existing rules requiring companies to demonstrate profitability before joining. This has strategic implications for AI lab valuations and public market access, as index inclusion typically drives significant institutional investment.
Cursor's Composer 2.5 rivals GPT-5.5 and Claude Opus 4.7 on coding benchmarks at lower cost
Cursor released Composer 2.5, a specialized agentic coding model built on Moonshot's Kimi K2.5 open weights with additional pretraining and reinforcement learning fine-tuning tailored to Cursor's own CLI harness. The model ranks third on the Artificial Analysis Coding Agent Index behind Claude Opus 4.7 and GPT-5.5 at max reasoning, but significantly undercuts them on cost ($0.44 vs $4.14 per task) and speed (6.7 vs 17.7 minutes). The training approach—co-optimizing model and harness together using synthetic tasks, text feedback during RL, and 25x more synthetic data than Composer 2—illustrates a specialist model strategy that challenges the dominance of generalist frontier models in coding workflows.
