On June 12, Tema Space Innovators ETF (NASA) fell 8.14% in regular trading, trading at $32.5099/share, with turnover of $598 million.

The sell-off was triggered by SpaceX officially beginning trading on Nasdaq under the ticker SPCX, causing investors to rapidly dump substitute space-themed holdings in favor of direct SpaceX exposure. Market data firm VandaTrack noted that retail investors had previously accumulated positions in space-concept ETFs purely as temporary placeholder stakes ahead of the IPO, and are now liquidating those proxies to rotate capital into SPCX.

The ETF had surged to become the largest space-themed fund globally, attracting over $2.6 billion in inflows within just two months, largely driven by its approximately 10% allocation to SpaceX through private market vehicles. With SpaceX now directly accessible on public markets, the substitute allocation thesis has collapsed, creating a powerful confluence of profit-taking and capital rotation pressure. French bank BNP Paribas estimated the broader swap-driven selling could trigger approximately $50 billion in concentrated position unwinding across related holdings.
