AI powerhouse Anthropic has announced a massive $6 billion secondary share sale program, allowing employees and early backers to monetize their stakes at a $350 billion valuation. This follows a fresh $30 billion Series G round that valued the company at $380 billion post-money. The liquidity event is designed to retain top talent in the fiercely competitive AI sector, allowing staff to convert their ESOPs without waiting for an IPO. This move solidifies Anthropic’s position as one of the most valuable private companies in the world.
