SpaceX's weight in the Nasdaq 100 index will rise to 2.82% when the index's quarterly rebalancing takes effect next Monday, up from about 1.28% now. According to Sina Finance, the final figure, calculated from Friday's closing price, matches the preliminary weight previously announced by the index compiler. SpaceX's weight has been relatively low since it was added to the index in July, when most of the company's shares were still locked up and unavailable for public trading. Even after Nasdaq changed its rules to allow newly listed large-cap stocks to enter the index more quickly and removed the requirement that at least 10% of a company's shares be freely tradable, that factor still weighed on its index weight. The expected increase will begin to narrow that gap. By market capitalization, SpaceX is the seventh-largest company in the Nasdaq 100, with a market value above $2 trillion, but by index weight it does not even rank in the top 20. The higher weight matters because passive funds tied to the benchmark must adjust their holdings accordingly. Those funds include the $482 billion Invesco QQQ Trust Series 1, known as QQQ, one of the largest ETFs. More than 200 investment products worldwide track the Nasdaq 100, with assets under management exceeding $800 billion. The Nasdaq 100 tracks large nonfinancial companies listed on the Nasdaq market. There is no minimum market-cap requirement for inclusion, but companies must have average daily trading volume of at least 200,000 shares and meet other conditions. Edward Yin of Macquarie Group said recent index rebalancing events have taken on greater significance amid multiple market drivers. He said the adjustment is taking place against a more volatile macro backdrop, citing geopolitical tensions involving Iran, persistent inflation concerns, renewed tariff uncertainty, interest-rate moves, and continued volatility in artificial intelligence and technology stocks.

Invesco Great Wall Fund said on September 19 that equity fund manager Liu Yanchun has stepped down as deputy general manager because of a work adjustment and will focus on investment management while continuing to manage funds, according to Jiemian News. Liu has 23 years of securities and fund industry experience, more than 17 years as a public fund manager, joined Invesco Great Wall in 2015 and was promoted to deputy general manager in 2021. Wind data showed that as of the end of the second quarter, Liu managed six funds with total assets of 24.049 billion yuan, including 12.45 billion yuan under his sole management. Before leaving the executive role, Invesco Great Wall had already added co-managers to several products: In May, Dingyi, Inner Consumption Growth and Inner Consumption Growth No. 2 were joined by Ke Haidong, Xu Yida and Liu; in June, Jiying Growth Two-Year Closed-End also added Meng Qi. After the changes, four of Liu's six funds are co-managed, while Xingxing Growth and Excellent Growth remain solely managed by him. The report said similar adjustments have been taking place across China's mutual fund industry. At E Fund, Xiao Nan, Chen Hao, Zhang Kun and Zhang Qinghua have all stepped down as deputy general managers since March 2025 to focus on investment management, while Hu Jian stepped down in July and continues to manage seven funds worth 58.623 billion yuan. Other recent cases include Changsheng Fund's Guo Kun in January, GF Fund's Fu Youxing in February, Pengyang Fund's Zhu Guoqing in July and Neuberger Berman Fund's Wei Xiaoxue more recently. Jiemian News also cited China's CSRC's May 2025 action plan on promoting high-quality development of public funds, which requires fund company shareholders and boards to give fund investment returns a weight of at least 50% in executive evaluations and fund performance a weight of at least 80% in fund manager evaluations.

Hut 8 co-founder Marc van der Chijs warned in a CoinDesk interview that intense competition between companies and nations is accelerating artificial intelligence development beyond human control, creating potential systemic risks for financial systems and critical infrastructure. According to ChainCatcher, he said the situation has already been lost to control and that systemic damage or catastrophic failure may be nearly unavoidable before real international guardrails are established. Van der Chijs said AI and robotics could eventually replace 90% to 95% of existing jobs and sharply reduce the cost of goods and services, forcing governments to seek new revenue sources such as taxes on robots or AI use. He also said AI could expose vulnerabilities in traditional banking software and weaken confidence in institutions that rely on interconnected systems. In crypto, he argued that businesses built around Bitcoin, such as exchanges, may be more vulnerable than the underlying network itself. He said he previously sold a large amount of Bitcoin to invest in AI and believes capital shifting into AI helped prevent Bitcoin from reaching his earlier $200,000 to $250,000 target. He is now reinvesting some AI profits into crypto assets through exchange-traded funds. Van der Chijs said he still views Bitcoin as the only asset worth holding for life and called Hut 8's move into AI data centers the best decision it has ever made.

Galaxy’s head of research said on X that the U.S. Securities and Exchange Commission has issued an "innovation exemption" to create a path for on-chain secondary trading of tokenized stocks. According to Odaily, the exemption will run from September 17, 2026, to September 17, 2031, and will apply to certain tokenized securities trading venues that offer permissioned automated market makers and liquidity pools. The venues must be deployed on public, permissionless blockchains, but trading will be limited to verified or authorized participants. Eligible tokens must correspond to actual U.S. National Market System stocks and grant the same shareholder rights as traditional shares. The exemption does not cover primary issuance, synthetic exposure, or products that do not carry legal or beneficial rights to the underlying stock. Galaxy said it is studying next steps for enabling on-chain secondary trading of GLXY.
