According to @KobeissiLetter, exchange-traded funds have surpassed individual U.S.-listed stocks for the first time, with over 4,300 ETFs versus roughly 4,200 companies, and the ETF count has doubled over the last eight years (source: The Kobeissi Letter post on X, Aug 26, 2025). This expansion includes spot Bitcoin ETFs, which the U.S. SEC allowed to list in January 2024, making ETFs a growing access channel for crypto exposure (source: U.S. SEC, Statement of Chair Gary Gensler on Bitcoin ETPs, Jan 10, 2024).
