The Tema Space ETF offers the rare direct SpaceX exposure among pure space-theme ETFs, and a SpaceX IPO should lift the whole fund beyond that holding. Its SpaceX SPV stake, about 8.73%, is valued near a $1.56 trillion SpaceX valuation versus about $2 trillion the market implies. A successful listing should spark the whole space sector, pulling up top holdings AST SpaceMobile, Rocket Lab and Intuitive Machines, perhaps by 40%. The fund is highly concentrated, with the top three over 44%. x.comÂ
