Moonshot AI Pauses Kimi K3 Subscriptions Amid IPO Plans

Moonshot AI, a Chinese startup, has temporarily paused new consumer subscriptions for its Kimi K3 model after a surge in demand pushed computing capacity to its limits over a 48-hour period. The company is prioritizing current members and adding capacity, with plans to reopen subscription slots in batches. To better manage resources, Moonshot will split memberships into two focused tiers: a general Kimi Membership and a coding-specific Kimi Code Membership.

The Kimi K3 is a 2.8 trillion-parameter open model with a 1-million-token context window, with full model weights expected by July 27, 2026. The rapid adoption of the model triggered volatility in global financial markets, as investors feared high-performing Chinese open-source models were eroding the competitive advantage of Western AI labs. This led to declines in semiconductor and memory stocks, contributing to a 2.6% drop in the Nasdaq.

Simultaneously, the company is preparing for an initial public offering in Hong Kong and is unwinding its offshore structure. Moonshot, which reached a $30 billion valuation in June, has engaged Goldman Sachs and China International Capital Corp as financial advisers. The startup is also seeking up to $2 billion in new capital to expand its computing infrastructure, a move necessitated by U.S. export controls on advanced Nvidia chips.
