SpaceX (NASDAQ: SPCX) experienced a 9% single-session drop on June 18, 2026, following reports that bankers are preparing a bond sale of at least $20 billion. This decline came just six days after the company priced the largest IPO in history at $135 per share, raising $75 billion. The stock, which hit an all-time high of $225.64 on June 16, pulled back to around $174, though it remains 29% above its IPO price. The volatility stems from a rapid succession of capital events, including a $60 billion all-stock acquisition of Anysphere and the looming bond sale, raising questions about capital requirements and execution risks.

The Week in Plain Numbers

The market debut was followed by immediate and aggressive capital deployment. On June 12, SPCX closed up 19% at $161.11. By June 16, the company announced it would acquire Anysphere, the parent company of AI coding tool Cursor, for $60 billion in stock. Cursor reportedly had roughly $4 billion in annualized recurring revenue prior to the deal. The stock subsequently pulled back 5.6% on June 17 before the additional 9% drop on June 18 upon news of the bond sale.

Valuation and Analyst Views

The rapid expansion has drawn scrutiny from analysts. Morningstar cut its fair value estimate to $62 following the acquisition, listing SPCX as one of the most expensive stocks in its coverage. At current prices around $174, the stock trades at approximately 3.2 times this estimate, implying potential downside. The firm noted that even at $63 per share, the valuation assumes significant benefit of the doubt. Former Nasdaq CEO Robert Greifeld also commented that the stock trades on hopes rather than fundamentals, though he acknowledged the company's visible momentum.

Capital Structure and Commitments

SpaceX is utilizing a multi-instrument approach to capital management. The IPO raised $75 billion in equity, while the Anysphere deal was conducted entirely in stock. The proposed $20 billion bond sale is intended to provide operational flexibility without diluting shareholders or using IPO proceeds. The company faces $25.45 billion in contractual commitments, primarily for cloud capacity, with 95% of those obligations due in 2026 and 2027. Additionally, the company is investing heavily in xAI, orbital data centers, and its commercial launch operations.

Lockup Structure and Float Risks

A key factor in the stock's volatility is the restricted float. Only about 5% of SPCX shares are currently tradable, with the remaining 95% locked up until December 8, 2026. This constrained supply contributes to violent price swings. The lockup structure includes tiered releases tied to performance and earnings. If SPCX closes at or above $175.50 for at least five of ten consecutive trading sessions around Q2 earnings, an additional 10% of locked shares becomes eligible. Furthermore, up to 20% of locked shares can be sold starting two trading days after the Q2 earnings report, expected around September 2. Elon Musk's personal holdings are subject to a separate 366-day lockup expiring June 12, 2027.

Business Fundamentals

Despite the valuation concerns, the underlying business metrics remain strong. Starlink has surpassed 12 million active subscribers, maintaining its position as the only satellite broadband network with global scale. The Falcon 9 rocket boasts a better than 99% success rate. The acquisition of Cursor adds $4 billion in enterprise AI software revenue. Analysts are also watching for the potential commercial payload flights of Starship in the second half of 2026, which could provide a significant cost-per-kilogram advantage.

Space Exploration Technologies Corp's SPCX stock has rapidly penetrated the ETF market, with its inclusion in both space-themed and value-oriented funds following its June 12 listing. The aerospace giant's presence in portfolios extends beyond niche space investments, signaling broad market acceptance. This development underscores the company's growing influence across diverse investment strategies.

Within days of its debut, SpaceX was added to the Procure Space ETF (UFO), which assigned it a 6.17% portfolio weight after the VettaFi Space Index reconstitution. Tuttle Capital Management also incorporated SPCX into three actively managed funds: the Tuttle Capital Space Industry Income Blast ETF (SPCI), Tuttle Capital UFO Disclosure ETF (UFOD), and Tuttle Capital Heavy Assets Low Obsolescence ETF (HALX). The Tema Space Innovators ETF (NASA), focused on the commercial space economy, already allocates 12.35% of its portfolio to SPCX.

ETF Allocations and Strategic Fit

ProcureAM confirmed SpaceX's inclusion in the VettaFi Space Index, citing its market capitalization, liquidity, and space-related revenues. Tuttle Capital highlighted SpaceX's versatility, noting its role in the space industry for SPCI and UFOD, while HALX's investment aligns with an AI infrastructure thesis. The firm emphasized SpaceX's orbital data center initiative, leveraging Starlink technology, as a key driver for its inclusion in HALX.

Value ETF Inclusion Sparks Discussion

SpaceX's appearance in the Schwab U.S. Large-Cap Value ETF (SCHV) surprised investors, as the fund typically targets mature, lower-valuation companies. The allocation, though negligible at 0.012% of SCHV's $15.8 billion asset base, challenges traditional ETF labels. It highlights how evolving businesses can fit into multiple investment categories as index methodologies adapt to market dynamics.

Future ETF Adoption

SpaceX's ETF footprint is expected to expand further, potentially entering AI infrastructure portfolios, broad-market indexes, and growth funds. For ETF investors, SpaceX is no longer just a niche space-industry bet but a stock that fund managers across categories cannot ignore.
