The Tema Space Innovators ETF (NYSE:NASA) launched at the end of March 2026 with a single genuinely differentiated feature: through a special-purpose vehicle, it offered direct exposure to SpaceX at a time when retail investors had no clean way to own the company. That advantage lasted about ten weeks. SpaceX went public in June 2026 at an IPO price of $135 per share, and the day the ticker started trading, the scarcity premium the fund had been built around effectively disappeared.
The stock did not float peacefully. SpaceX closed below its IPO price for the first time on July 16, 2026, before climbing back above it in early August on its first earnings report, which beat on revenue. The NASA ETF itself has traded roughly in sympathy, down roughly 29% between June 1 and August 14. That leaves prospective buyers with a cleaner question than they had at launch: with the access premium gone, what is the rest of the fund actually buying you?
The Access Premium That Evaporated
Before the IPO, an SPV holding pre-listing SpaceX shares inside a regulated ETF wrapper was a real product. Accredited-investor structures traded at wide premiums to net asset value, private secondary markets required minimum tickets most people could not write, and tokenized share workarounds carried counterparty risk. NASA offered a listed alternative and aggressively collected assets, ending May with net assets of roughly $2.6 billion.
The composition of that pot matters. Per the fund’s most recent NPORT filing, SpaceX now sits at roughly 7% of net assets across preferred and common SPV positions, while Rocket Lab is the largest single holding at 11%. A buyer today is getting SpaceX as the third- or fourth-largest name in a diversified basket, one that an investor can now replicate for the price of a brokerage commission.
The Basket Behind the Headline
The remaining 38 positions span launch (Rocket Lab, Firefly), satellite broadband (AST SpaceMobile, Viasat, Iridium), earth imaging (Planet Labs, BlackSky), and lunar and national-security work (Intuitive Machines), with a long tail of international suppliers. Many of these companies are small, structurally unprofitable, and heavily reliant on government awards, though the underlying growth is real: Rocket Lab reported Q2 revenue of $234 million, up 62% year over year, with backlog at a record $2.36 billion, and Intuitive Machines posted Q2 revenue of $206 million, more than four times a year earlier, with a $1.76 billion backlog.
The dispersion within that group is what a fund actually solves. Since June 1, Intuitive Machines is down 50%, Firefly is down 40%, and Viasat is up 14%. Picking the winner in a sector where sentiment can swing 40% on a single Space Force budget headline is not obvious, and Reddit’s own retail community has been openly debating whether the summer drawdown was a “generational buying opportunity” or exit liquidity. A diversified sleeve makes that call less catastrophic in either direction.
Does This Fit Your Portfolio?
Weighed against what NASA now provides rather than what it once provided, the roughly 0.75% expense ratio is the tax an investor pays for the sector basket itself. That tax is defensible if the buyer genuinely wants exposure to space as a theme, cannot construct a comparable basket in a taxable brokerage account, and values the fund’s international small-cap holdings that would otherwise be a hassle to own directly.
An investor whose real conviction is SpaceX can access the name directly and skip the fund fee. An investor who wanted broad space exposure and never cared much about the SPV can reasonably use the fund as a 3% to 5% thematic sleeve, understanding that the underlying holdings are largely government-contract-dependent, cash-burning growth names whose earnings will remain volatile for years.
