Summary
The most closely watched pending event is Anthropic's IPO, which is widely expected the week after next. According to The Wall Street Journal, citing unnamed sources, some major investors are growing doubtful that Anthropic can complete a listing valuing it at up to $1.5 trillion. One investor suggested the company might need to raise less capital, while another said a delay may be necessary until market conditions stabilize. Kalshi odds that Anthropic goes public before December 1 have fallen sharply in the past week, and the outlook for rival OpenAI, also an IPO hopeful, appears more challenging.
The broader market impact has been significant. The sell-off pushed benchmark indexes in Seoul, Tokyo and Taipei, all home to companies that had benefited strongly from the AI boom, into bear markets or close to them. The S&P 500 suffered its worst one-day loss since April 2025, during the period of President Trump's "Liberation Day" tariffs. Hedge funds are reportedly unwinding their riskiest positions, including exposure to AI companies. The 10-year Treasury yield stood at 4.87 percent, and government bonds worldwide rallied as investors sought safer assets.
The newsletter also points to political and regulatory risk. Following Democratic election victories, the author argues that the more immediate bottleneck for AI companies lies at the state level, where a new wave of Democratic governors and legislatures are poised to tighten data center permitting. That prospect, the newsletter suggests, casts doubt on Anthropic's IPO and could unravel the sector's circular financing arrangements if the deal is delayed or falters. Talk of an AI bubble has persisted for over a year, but investors have repeatedly looked past concerns including a memory chip shortage, energy bottlenecks and high financing costs.
