XOVR holds a significant private market position in SpaceX, and despite AUM spikes diluting the weight, the fund is actively buying more to maintain its exposure ahead of a potential IPO. Retail and public market investors have virtually no way to access pre-IPO shares of highly valued private companies like SpaceX; an ETF that manages to secure and hold these shares offers a unique, scarce exposure that could pop upon an IPO announcement. WATCH XOVR for rare public-vehicle access to SpaceX equity. The SEC limits illiquid assets in open-ended funds to 15 percent, and regulatory pressure could force the fund to alter its structure or sell down its prized private holdings.
