The Hidden Risk Behind ETF Growth | Eric Balchunas and Dave Nadig Debate If We've Gone Too Far

ETF innovation or madness?

In this episode of Rabbithole, Dave Nadig is joined by Bloomberg’s Eric Balchunas for a candid and wide-ranging conversation on the explosion of new ETFs—some useful, some ridiculous, and some outright dangerous. They debate where the line should be drawn between investor freedom and regulatory responsibility, why the current ETF boom feels different, and whether the rise of private markets and derivatives in ETFs is creating cracks in the financial system. From yield-maxing “hot sauce” products to private equity in public wrappers, this is a no-holds-barred look at where the ETF industry is heading.
