Anthropic is preparing for a high-profile IPO, with recent funding rounds suggesting a potential $1–2.45 trillion valuation. Momentum trading and oversubscription could drive ANTHRO shares higher at the open, but post-IPO volatility is likely, as seen with recent tech IPOs. Indirect stakeholders like AMZN, GOOG, MSFT, and AVGO may see volatility as investors rotate into ANTHRO, while satellite and communications stocks could face selling pressure.
