Roundhill Space & Technology ETF Gains 53% While Rival NASA ETF Faces SpaceX Dilution
Roundhill Space & Technology ETF (MARS) has surged 53% since inception, outpacing the 46% gain of the recently launched Tema Space Innovators ETF (NASA) despite NASA reaching $1.3 billion in AUM. Massive inflows into NASA reduced its SpaceX weighting from 10.3% to 4.6%, highlighting MARS’s focused performance.
1. MARS Outperformance and Returns
Roundhill Space & Technology ETF (MARS) has delivered a 53% return since launch, exceeding the 46% rise recorded by the Tema Space Innovators ETF (NASA) over the same period. This performance differential underscores MARS’s early-mover advantage and targeted exposure to space and technology companies.
2. NASA ETF AUM Surge
The NASA ETF hit nearly $1.3 billion in assets under management after $375 million of inflows in a single day, tripling its AUM since late March. Its rapid growth vaulted it past earlier entrants like Procure Space ETF and ARK Space & Defense Innovation ETF to become the largest space-themed ETF.
3. SpaceX Allocation Decline
Heavy new capital in the NASA ETF outpaced the manager’s ability to scale its private SpaceX holding, cutting the weighting from 10.3% to just 4.6%. Excess inflows were redirected into public equities, diluting the very exposure that initially attracted investors.
4. Implications for MARS
With no private holding dilution and a clear performance edge, MARS may appeal more to investors seeking consistent space exposure. The dilution issues at NASA ETF could redirect future inflows toward MARS, reinforcing its growth trajectory.
