Key Takeaways
- In only 37 trading days following its March 31 launch, the Tema Space Innovators ETF (NASA) reached $1 billion in assets under management.
- With $1.27 billion in AUM, NASA has become the space sector’s largest ETF, surpassing both UFO and ARKX.
- NASA stands alone as the only space-focused ETF offering investors exposure to SpaceX, which submitted its S-1 filing in June ahead of going public.
- A single-day influx of $375 million on Wednesday demonstrated how SpaceX’s upcoming IPO is driving capital into the fund.
- Paradoxically, while investors pile into NASA seeking SpaceX exposure, the company’s portfolio weight has dropped from 10.3% to just 4.6% due to dilution from new capital.
The Tema Space Innovators ETF, which trades under the ticker NASA, crossed the $1 billion assets under management threshold in a mere 37 trading days. This achievement positions it as the second-fastest thematic ETF and ranks it among the top five quickest active equity ETFs to reach this benchmark out of over 1,700 competing products.
Tema Space Innovators ETF, NASA
Launching on March 31 with just $1 million in seed funding, the fund has rapidly expanded to $1.27 billion in total assets.
Since its debut, the ETF has climbed 46%, significantly outperforming competitors UFO (up 32%) and ARKX (up 17%) during the identical timeframe. The only space ETF with superior returns is the Roundhill Space & Technology ETF (MARS), which posted 53% gains over the same window.
NASA’s primary appeal is straightforward: it’s the sole space ETF providing access to SpaceX.
Following SpaceX’s S-1 filing on Wednesday in preparation for next month’s planned IPO, the fund experienced a surge in interest. On that day alone, NASA attracted $375 million in new investments.
SpaceX Public Offering Drives Capital Rush
The forthcoming SpaceX IPO has emerged as one of the most eagerly awaited public offerings in recent memory. For market participants seeking pre-IPO exposure to the company, NASA has represented the sole ETF pathway.
This exclusive 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 captured substantial inflows this year—$456 million and $143 million respectively—neither approaches NASA’s meteoric growth.
The fund gains SpaceX exposure through a Special Purpose Vehicle structure. While this mechanism enables the private company holding, it introduces complications.
The Dilution Dilemma
Here’s the counterintuitive reality: as more capital floods into NASA specifically for SpaceX access, each investor’s actual SpaceX exposure diminishes.
When substantial inflows enter an ETF, portfolio managers must rapidly allocate that capital. Unlike publicly traded securities, private holdings like SpaceX can’t simply be purchased through open markets. Consequently, incoming funds flow into publicly available stocks, systematically diluting the private position.
Just last week, SpaceX represented 10.3% of the portfolio. Today, that figure stands at 4.6%.
Interestingly, SpaceX hasn’t been the primary contributor to the fund’s strong performance—most gains have originated from publicly listed holdings. Nevertheless, SpaceX’s mere presence in the portfolio has proven sufficient to establish NASA as the leading force in the space ETF segment.
Tema President Steve Munroe explained the fund was designed to provide “institutional-quality” exposure to the space economy, including pre-IPO access to companies like SpaceX.
As of Wednesday’s close, NASA had tripled its total assets in just seven days.
