Musk plans to give every child in the US one SpaceX share next year, worth about $11 billion at current share prices; Anthropic announced it will donate 5% of the company's shares to a new philanthropic fund. OpenAI and Wiz used AI tools including GPT-5.6 Sol to find a memory leak and a remote code execution vulnerability in the PHP core engine, and the PHP team released a security update on October 21.
