At ETF Exchange 2026, TMX VettaFi caught up with Dave Mazza, CEO of Roundhill Investments, to discuss the firm’s evolving strategy for ETF innovation in a market that’s continuously seeking specialized exposure. Looking beyond the typical artificial intelligence (AI) trade, Mazza noted that Roundhill is focusing on the next frontier of opportunities, which include space technology and robotics.
Based on ETFdb data, Roundhill has over $7 billion in assets dispersed over 48 ETFs. The firm accumulated more than half of those assets over the past year with the launch of new ETFs that included a plethora of single-stock funds. Needless to say, it’s been a busy 12 months.
Innovation at Work
Roundhill has been leading ETF innovation by building products with broad-based appeal and liquidity. A prime example of this innovation at work is the Roundhill WeeklyPay ETF series. This suite offers investors 120% amplified exposure coupled with weekly distributions. Mazza noted that it fits income investors seeking household names in the stock market with built-in volatility to generate yield.
“When we think about single stocks, we’re really looking for those that have broad-based appeal,” Mazza said. “These are well-known to a wide range of investors, and then have the liquidity, trading volume, size, and scale that would be required to create an ETF on top of it.”
When it comes to topical investment themes, Mazza is particularly bullish on the transition of the space economy from government exploration to commercial-scale infrastructure. Enter the launch of the Roundhill Space & Technology ETF (MARS), which debuted in early March. The fund offers pure-play exposure to companies powering satellite connectivity and GPS, positioning itself ahead of industry milestones such as a potential SpaceX IPO.
Furthermore, Roundhill is looking at opportunities in embodied AI. The Roundhill Humanoid Robotics ETF (HUMN ), for example, focuses on the application of AI in physical forms. Mazza noted that the AI theme is moving beyond training models. This involves inference and the application of AI where it can be used in various scenarios to make real-time decisions. HUMN is poised to capture these future opportunities.
Meeting Investor Demand
Roundhill isn’t the type of firm that simply throws ideas against a wall to see what sticks. While the firm is an idea lab for product innovation, it all begins with the investor. The firm looks to fill needs that speak to investors the most. This premise will serve as a guidepost for the industry moving forward.
“It’s always helpful to be attuned to what’s happening in the market and where there’s interest for investors,” Mazza said. “Really the idea that ETFs can serve as a solution for outcome-oriented investments is where I think the industry is going.”
“We’ve purposefully laid out a strategy that wants to opportunistically participate in areas where we think appeal, but to different types of investors,” Mazza added.
