On September 14, ProShares UltraPro QQQ declined 5.09% in regular trading, trading at $68.675/share, with turnover of $1.439 billion.

On the news front, Anthropic CEO Dario Amodei issued a public warning about AI losing control, calling on the industry to slow the pace of frontier AI model capability advancement and introduce permanent third-party safety evaluation teams. OpenAI CEO Sam Altman and xAI founder Elon Musk both publicly expressed support. This rare consensus among top AI leaders sparked widespread concern that the tech industry growth trajectory could materially decelerate, with Hong Kong-listed AI stocks already coming under pressure ahead of the U.S. session. Simultaneously, market expectations for the Federal Reserve to raise interest rates by 25 basis points next week continued to intensify following stronger-than-expected core CPI data, further amplifying selling pressure on risk assets.

ProShares UltraPro QQQ is a triple-leveraged ETF tracking the Nasdaq-100 Index, which includes 100 of the largest domestic and international non-financial companies listed on the Nasdaq Stock Market based on market capitalization. The fund invests in financial instruments designed to produce daily returns consistent with three times the daily performance of the index, meaning volatility in tech heavyweights is significantly amplified.
