Morning newsletter digest

Fortune Term Sheet: “Cerebras rising”

• Cerebras finally hit the public markets after earlier filing drama, and shares rocketed nearly 70% by the close.
• The newsletter frames the OpenAI partnership as the key narrative upgrade since investor worries in 2024 around customer concentration, G42 ties, and CEO Andrew Feldman’s past issues.
• The real test is now execution: manufacturing volume, delivery reliability, and proving demand beyond OpenAI.

Why it matters: The market is treating credible AI infrastructure challengers like rare animals at the zoo: everyone wants a photo, nobody is sure what they eat yet.

The Rundown AI: “OpenAI’s Codex escapes the desktop”

• OpenAI rolled out Codex in preview inside the ChatGPT iOS app, letting developers monitor tasks, approve changes, view code threads, and start new tasks from mobile.
• The mobile setup uses a secure relay layer and is clearly aimed at the same “keep agents moving while away from desk” problem Anthropic has been chasing.
• The issue to watch: OpenAI’s Apple relationship is reportedly deteriorating, with OpenAI considering legal options over the ChatGPT-Siri partnership.

Why it matters: Long-running coding agents become much more useful if they do not require babysitting a laptop like it is a sourdough starter.

Short Squeez: “Welcome to the AI IPO Era”

• Cerebras raised $5.55B in the largest U.S. tech IPO since Uber, priced at $185, opened at $350, and closed up 68% at $311.07.
• The newsletter highlights the wild repricing: roughly $23B valuation in February, near $40B at IPO, and about $95B by Thursday’s close.
• Other top reads include JPMorgan’s private credit push, PE portfolio thawing, Blackstone’s data center REIT IPO, and Anthropic tightening Claude limits as OpenAI courts agent users.

Why it matters: If you are an “AI” company with a credible infrastructure story, the IPO window appears to be wide open. For everyone else, probably still a window, but maybe one of those tiny bathroom ones.

Axios Pro Rata: “Cerebras cash”

• Axios also centers on Cerebras, calling it the year’s largest IPO and noting it priced far above the original $115-$125 range.
• Dan Primack flags VC and PE figures running for office, including Mike Minogue and Brian Shortsleeve in Massachusetts and Tom Steyer in California.
• Deal flow included Recursive Superintelligence confirming a $650M raise at a $4.65B post-money valuation, plus large rounds for Quantum Systems, Mind Robotics, and Fractile.

Why it matters: The Cerebras debut is not just an AI-chip story. It is a liquidity and sentiment signal for venture, late-stage AI, and bankers who have been waiting for signs of life.
