In this discussion, recorded at the Exchange ETF conference in Las Vegas in mid-March, I joined Mark Gochnour from Dimensional Fund Advisors to explore the massive expansion and structural evolution of the ETF marketplace. With the industry surpassing 5,000 products, the conversation highlighted the transition from the first index-based launches in the 1990s to the current era of high-velocity innovation.
Key Topics Covered
- The Rise of Active Management: We discussed how the “ETF Rule” (Rule 6c-11) served as a catalyst for mutual fund managers to enter the space, leading to a record-breaking 1,100 launches in 2025 alone.
- Complex Strategies and Education: Investor due diligence is paramount as products become more sophisticated. We explored the risks and use cases for thematic funds, covered call strategies, and the surging interest in leveraged or single-stock ETFs.
- The New Frontier of Share Classes: We placed major focus on the SEC’s recent exemptive relief allowing more firms to offer ETF share classes of existing mutual funds. We saw this as a marathon rather than a sprint. It has the potential to significantly scale assets and improve tax efficiency once the “plumbing” is fully automated.
- Global Growth and Future Vehicles: Our dialogue touched on the rapid growth of the European ETF market and the long-standing structural hurdles to integrating ETFs into 401(k) plans.
The session concluded against the backdrop of Las Vegas. With $400 billion in net inflows already recorded by mid-March, 2026 is on pace to be another record-breaking year for the industry.
