Anthropic has shifted its expected record-breaking initial public offering (IPO), or first sale of shares to the public, from October to November, according to people familiar with the matter. The timing change came before public discussion of AI safety intensified last week, and the company plans to meet prospective investors in the coming days. The newsletter also reports that Berkshire's chairman is retiring after leading the company for more than sixty years, while remaining on its board as chairman emeritus. His 71-year-old son Howard is the successor highlighted in the coverage. Separately, NASA and Boeing have discussed using the Starliner spacecraft for 10 or more flights in coming years. Starliner has not flown since 2024, when technical problems left two astronauts aboard the International Space Station for months, and NASA is assessing commercial transportation options to sustain a presence in low Earth orbit.
