Elon Musk is taking SpaceX’s minority shareholders for a ride | Nils Pratley

By Nils Pratley

AI Analysis

Continuing our coverage from yesterday, Elon Musk is merging SpaceX with xAI at a $1.25 trillion valuation, creating what would be the most valuable private company in history ahead of a June IPO. Critics view this as potentially propping up the loss-making xAI rather than a genuine strategic combination.

AI Analysis

Building on yesterday's Social buzz, Nvidia's planned $100B investment in OpenAI has not materialized 5 months after announcement, with OpenAI reportedly seeking alternatives to Nvidia chips due to inference speed issues with Codex. Jensen Huang now says the figure was 'never a commitment.'

The rise of Moltbook suggests viral AI prompts may be the next big security threat

By Benj Edwards

75 score
AI Analysis

Security researchers warn that Moltbook, a new platform, is enabling viral AI prompts that could replicate across AI agent networks similar to the 1988 Morris worm. This represents a novel attack vector for agentic AI systems.

On November 2, 1988, graduate student Robert Morris released a self-replicating program into the early Internet. Within 24 hours, the Morris worm had infected roughly 10 percent of all connected computers, crashing systems at Harvard, Stanford, NASA, and Lawrence Livermore National Laboratory. The worm exploited security flaws in Unix systems that administrators knew existed but had not bothered to patch. Morris did not intend to cause damage. He wanted to measure the size of the Internet.
