Moonshot (Kimi)’s technological breakthrough triggers sell-offs in AI stocks, with leveraged products amplifying market volatility.

According to Bloomberg, Chinese AI startup Moonshot has achieved an unexpected technological breakthrough, triggering sharp declines in global AI and semiconductor stocks on Friday and prompting markets to once again reference the 2025 "DeepSeek Moment". The semiconductor benchmark index has fallen roughly 20% from its June peak, entering a bear market; the triple-leveraged semiconductor ETF SOXL has dropped more than 50% over the same period. This sell-off demonstrates that when rapid advances in AI technology reshape market perceptions of winners and losers, leveraged ETFs, options, single-stock funds, and crypto-related products may be liquidated simultaneously. Bloomberg Intelligence data shows leveraged ETFs make up around 13% of U.S. ETF trading volume but only 1.2% of industry assets. When accounting for embedded leverage, their share of the U.S. stock market remains less than 1%. While these products are generally small in overall size, their holdings are concentrated in AI chips, volatile stocks, and newly listed firms. When leverage, concentration, and volatility rise at the same time, the funds' daily rebalancing turns them into active trading forces that further amplify existing market trends. The South Korean market offers a clear recent case: local retail investors have heavily purchased leveraged products tied to Samsung Electronics and SK Hynix, and as market sentiment turned weak, the related funds were forced to sell an estimated tens of billions of dollars worth of SK Hynix positions.
