Key Highlights
- Tema Space Innovators ETF (NASA) achieved $1 billion in assets under management within only 37 trading sessions following its March 31 debut.
- With $1.27 billion in AUM, NASA has become the space sector’s largest ETF, surpassing competitors UFO and ARKX.
- NASA stands alone as the only space-focused ETF offering investors access to SpaceX, which submitted its S-1 filing for public trading in June.
- The fund attracted an extraordinary $375 million in net inflows during a single trading session Wednesday amid growing SpaceX IPO enthusiasm.
- Paradoxically, while investors flock to NASA for SpaceX access, the rocket company’s portfolio allocation has declined from 10.3% to just 4.6% due to dilution from incoming capital.
The Tema Space Innovators ETF, which trades under the ticker NASA, achieved the $1 billion assets under management benchmark in a mere 37 trading sessions. This remarkable accomplishment positions it as the second-fastest growing thematic ETF and ranks it among the top five quickest active equity ETFs to reach this threshold from a universe of over 1,700 investment products.
Tema Space Innovators ETF, NASA
Launching on March 31 with just $1 million in initial seed funding, the fund has rapidly expanded to command $1.27 billion in total assets.
Since its inception, the ETF has delivered impressive returns of 46%, significantly outperforming competitors UFO (up 32%) and ARKX (up 17%) during the identical timeframe. The only space ETF with superior performance is the Roundhill Space & Technology ETF (MARS), which gained 53% over the same period.
The primary attraction for NASA is straightforward: it represents the sole space-themed ETF providing access to SpaceX.
When SpaceX submitted its S-1 filing on Wednesday in preparation for next month’s anticipated IPO, it seemingly catalyzed a massive influx of capital. The fund recorded $375 million in inflows within 24 hours.
SpaceX Public Listing Anticipation Drives Record Inflows
The forthcoming SpaceX public offering has emerged as among the most eagerly awaited IPOs in recent memory. For market participants seeking early exposure before shares begin trading publicly, NASA has represented the exclusive ETF vehicle.
This unique positioning has propelled NASA ahead of more established competitors. UFO, despite its longer market presence, currently manages $972 million in assets. ARKX holds $944 million. While both funds have experienced solid inflowsā$456 million and $143 million respectively year-to-dateāneither approaches NASA’s momentum.
The fund gains SpaceX exposure through a Special Purpose Vehicle structure, or SPV. While this framework enables the private company holding, it introduces operational complications.
The Dilution Paradox
Here lies the counterintuitive challenge: as more capital enters NASA specifically for SpaceX access, individual investors’ proportional exposure to SpaceX actually diminishes.
When substantial inflows arrive at an ETF, portfolio managers must rapidly allocate that capital. With privately held securities like SpaceX, purchasing additional shares through traditional market channels isn’t possible. Consequently, fresh capital gets invested in publicly traded portfolio companies, reducing the private holding’s relative weight.
Just last week, SpaceX comprised 10.3% of the fund’s holdings. Today that figure stands at 4.6%.
Interestingly, SpaceX hasn’t contributed substantially to the fund’s strong performanceāthe returns have primarily originated from publicly traded positions. Nevertheless, SpaceX’s presence in the portfolio alone has proven sufficient to establish NASA as the dominant force in the space ETF category.
Tema President Steve Munroe indicated the fund was designed to provide “institutional-quality” exposure to the space industry, including pre-IPO access to SpaceX.
As of Wednesday’s close, NASA had tripled its assets under management within a single week.
