Space Exploration Technologies Corp's (NASDAQ:SPCX) blockbuster public debut has kept the ETF market on its toes, with the aerospace giant rapidly finding its way into portfolios far beyond the space-investing niche.

Within days of its June 12 listing, SpaceX was added to several space-focused and thematic ETFs, including the Procure Space ETF (NASDAQ:UFO), which assigned the stock a 6.17% portfolio weight following the latest VettaFi Space Index reconstitution.

At the same time, Tuttle Capital Management added SPCX to three actively managed funds—the Tuttle Capital Space Industry Income Blast ETF (BATS:SPCI), Tuttle Capital UFO Disclosure ETF (BATS:UFOD), and Tuttle Capital Heavy Assets Low Obsolescence ETF (BATS:HALX).

The Tema Space Innovators ETF (NYSE:NASA), explicitly focused on the commercial space economy and the premier vehicle for investors seeking concentrated SpaceX exposure before the IPO, already allocates 12.35% of its portfolio to SPCX.

But it wasn't the additions by space-themed ETFs that caught investors' attention.
