The exchange-traded funds (ETF) sector is preparing for big changes starting in 2025, and who wins Tuesday's election might influence these changes. A likely victory for Republican Donald Trump could mean less strict rules than the past four years. Whoever comes into office, ETF companies are getting ready. Some new fund ideas, like using private credit, have already been proposed to the Securities and Exchange Commission (SEC). Private loans don't always fit well in ETFs because they can't be easily sold daily. Big firms like State Street and Apollo have ideas on how to make this work. Another key area is whether the SEC will allow companies to offer both mutual fund and ETF share classes. Vanguard already does this, but others want in. This could make some top mutual funds more accessible and help stop money from flowing out of companies. Cryptocurrency is also a hot topic. Bitcoin ETFs did really well in 2024, and ether ETFs are close behind. Who becomes the new SEC chair could affect the future of crypto ETFs. Right now, there are applications for XRP and solana ETFs. Some smaller coins might do better with a Trump win than with Vice President Kamala Harris. ETF companies want to be ready for any changes.
