BlockBeats News, May 30th - As SpaceX prepares for its upcoming IPO, retail investors in the US stock market are rushing into space-themed ETFs. Among them, the NASA Fund (Space Innovators ETF) launched by Tema ETFs has emerged as the biggest winner. The fund, which was listed on March 30th, broke through $1 billion in assets in just 37 trading days and has surged to over $2.6 billion by the end of this week. The fund holds SpaceX private shares directly, accounting for approximately 7.5% of the fund's holdings, providing retail investors with a convenient way to gain exposure to SpaceX before its IPO. Maurits Pot, the founder of Tema ETFs, stated that any space investment must include SpaceX, and post-IPO, the fund will not sell its shares but will only reevaluate its holdings at market prices. Market experts believe that the space investment frenzy may replicate the early-stage AI investment boom but with significant volatility. The Blue Origin rocket explosion incident this week once again highlighted the industry's early-stage uncertainty. Investors should expect some companies to soar while also being cautious as some may face setbacks.
