(Bloomberg) -- Moonshot AI is preparing to begin discussions in August on a final round of fundraising before listing in Hong Kong, capitalizing on the excitement around its latest model to raise capital at a valuation of as much as $50 billion. That should mark the final infusion of capital for Moonshot before an initial public offering as soon as this year. The 2.8 trillion-parameter Kimi K3 — billed as the world's largest open-weight AI model — surprised developers and investors with performance approaching the latest frontier models from OpenAI and Anthropic PBC. Since the K3's launch, daily sales have surged at least six times, one person familiar with the matter has said. The explosive debut of its latest AI model last week was a vindication of sorts for founder Yang Zhilin, the reclusive 33-year-old alumnus of Carnegie Mellon University, Meta Platforms Inc. and Alphabet Inc.'s Google.
