**Trader sentiment on the "Which CEOs will be out before 2027?" market reflects elevated tech executive turnover amid the AI transition, with Tim Cook's September 2026 departure from Apple (succeeded by John Ternus) driving near-certain resolution on that outcome.** Other named CEOs like Andy Jassy (Amazon), Sundar Pichai (Google), Sam Altman (OpenAI), and Brian Armstrong (Coinbase) carry low implied probabilities (roughly 5-10%), as traders see continuity despite sector-wide churn. Recent catalysts include OpenAI's ongoing executive exits tied to reorganization and safety debates, Google DeepMind talent departures for startups, Microsoft leadership shuffles around Office/Teams/Copilot, and AI researcher resignations at Anthropic and elsewhere citing rapid capability scaling risks. Competitive pressures from large language model releases, compute demands, and regulatory scrutiny on AI deployment continue to shape board expectations, though most long-tenured leaders face no immediate succession triggers before year-end.
