SpaceX completed its first week as a publicly traded company with shares at $185, still 37% above the $135 initial public offering price but well off the Tuesday peak of $225.64. The early rally, fueled by scarcity and enthusiasm for Elon Musk's space venture, has given way to a more complex market structure story involving ETF flows, lock-up schedules and retail trading rules.
ARK ETF Activity Spurs Volatility
The sharpest signal came from Cathie Wood's ARK Innovation ETF, which saw a record $4.6 billion inflow late last week followed by a $6.2 billion outflow the next session, according to Bloomberg. This coincided with ARKK acquiring roughly 1.7 million SpaceX shares on listing day. ETF specialists described the pattern as possible IPO arbitrage, where investors use the fund to gain exposure then quickly exit.
ARK has not treated the move as a one-day trade. Barron's reported that ARK bought 54,815 Tesla shares across two funds after selling some Tesla last week, apparently to make room for SpaceX. As of June 12, ARK held about 3.29 million SpaceX shares, while Tesla remained its top holding in ARKK.
Retail Investors Face Restrictions
Small investors received only a fraction of their requested SpaceX IPO shares, according to CNBC via TheStreet, while several brokers imposed anti-flipping penalties on early sales. Fidelity, Robinhood and SoFi apply holding windows or IPO-access restrictions, while Schwab was described as an outlier with no anti-flipping policy unless required by the issuer.
Lock-Up Schedule Adds Supply Risk
Reuters reported that up to 20% of restricted shares can be sold after second-quarter earnings, with another 10% tied to the stock staying at least 30% above the offering price. Mayer Brown attorney Ali Perry said the staggered structure "smoothes out the initial impact" but does not remove it.
Valuation Skeptics and Ratings
Paul Meeks, head of technology research at Freedom Capital Markets, told Business Insider he thought SpaceX fair value was around $63 a share and said the market was "investing in the Elon Musk cult." He also noted options-implied volatility of 97.5%, a measure of expected price swings over the next year.
Countering this, Moody's, Fitch and S&P Global Ratings gave SpaceX investment-grade ratings with stable outlooks after the IPO. S&P cited strength in space and connectivity businesses while flagging uncertainty in AI due to high capital needs and competition.
Index Inclusion Fuels Demand
FTSE Russell said SpaceX will be added to the Russell 1000, Russell Top 200 and other Russell U.S. indexes after the close on June 26. MSCI is set to add the stock on June 29, and Jefferies estimated $2.68 billion of passive inflows from FTSE Russell inclusion. Franklin Templeton's Dina Ting noted that "the real story is about index methodology."
Broader Market Impact
SpaceX's wobble has hit peers: when shares fell on Thursday, Rocket Lab and Planet Labs dropped around 3%, while AST SpaceMobile and Intuitive Machines also declined, according to Reuters. The reaction suggests SpaceX now sets the tone for the listed space trade.
The first earnings report could be pivotal as new supply becomes eligible for sale and investors question AI spending. SpaceX agreed to buy Anysphere, the startup behind Cursor, in a $60 billion all-stock deal, and bankers are preparing a bond offering of at least $20 billion, Reuters reported. Strong index demand could cushion the stock; a weak earnings print or another AI funding surprise could do the opposite.
