SpaceX IPO Frenzy Cools as Wall Street Braces for $1.77 Trillion Index Inclusion

The aerospace and technology landscape was permanently altered last week when SpaceX completed the largest initial public offering in history. Debuting on the Nasdaq under the ticker SPCX on June 12, the company raised a staggering $75 billion, achieving an implied valuation of $1.77 trillion.[5][7]

The sheer scale of the offering immediately reshuffled the ranks of the world's most valuable public companies. Opening at $150—an 11% premium over its $135 IPO price—the stock surged to close its first day near $161, pushing its market capitalization past $2.1 trillion. This catapulted SpaceX ahead of legacy giants like Broadcom and Saudi Aramco, cementing its status as a foundational pillar of the modern market.[2][7]

The historic debut also marked a personal milestone for founder Elon Musk. With his retained equity in the newly public entity, Musk's net worth eclipsed the $1 trillion mark, making him the world's first trillionaire. The wealth generation extended to early employees and private backers who had sustained the company through two decades of capital-intensive development.[2][7]

Now, just over a week after the opening bell, the initial retail frenzy that drove unprecedented trading volumes is beginning to cool. Shares have experienced typical post-IPO volatility as early momentum traders take profits. However, market analysts warn that a second, potentially larger wave of capital is quietly preparing to strike.[1]

The catalyst for this impending surge is SpaceX's fast-tracked inclusion into major market indices. Having secured a rare rule change, SPCX is slated to enter the Nasdaq-100 index just 15 trading days after its IPO, alongside entry into the CRSP US Total Market Index.[4][7]

This accelerated timeline forces passive index funds and institutional asset managers to accumulate massive positions in a highly compressed window. Because these funds must mirror the index composition, their buying is price-agnostic, creating a structural demand shock that could easily overwhelm the relatively small 5% public float.[4][7]

The enthusiasm driving both retail and institutional demand is rooted in SpaceX's transformation from a pure-play rocket builder into a diversified technology conglomerate. The company currently operates three distinct business segments, each with radically different financial profiles and growth trajectories.[4]

The foundational pillar remains its launch business, which has achieved a near-monopoly in orbital delivery. In 2025, SpaceX was responsible for 83% of the global mass delivered to orbit, leveraging its reusable rocket architecture to slash launch costs by more than 95% compared to legacy competitors.[4]

The second engine is Starlink, the satellite internet constellation that has rapidly scaled to over 9 million active users. While average revenue per user has slightly declined as the service expands into emerging markets, Starlink provides the recurring, high-margin subscription revenue that Wall Street traditionally rewards.[4][6]

But the true driver of the $1.77 trillion valuation is the company's aggressive pivot into artificial intelligence. In February 2026, SpaceX acquired Musk's AI venture, xAI, integrating its Grok models and proprietary Colossus data centers into the broader aerospace framework.[5][7]

The company's S-1 prospectus leaned heavily on this AI integration, outlining long-term ambitions to build orbital data centers that bypass terrestrial power constraints. A recently secured long-term contract to provide AI compute infrastructure for Anthropic has lent early credibility to this third revenue stream, positioning SpaceX as an AI infrastructure play rather than just an aerospace firm.[4][7]

Despite the overwhelming market enthusiasm, a vocal contingent of value analysts is urging caution. Morningstar recently initiated coverage of SPCX with a fair value estimate of just $63 per share—roughly 55% below its IPO price.[3]

These skeptics argue that while the launch and Starlink businesses possess a narrow economic moat, the AI segment's prospects remain highly speculative. They caution that pricing the company at nearly 94 times its trailing 2025 revenue of $18.7 billion leaves virtually no margin of safety for public investors.[3][4]

Furthermore, analysts warn of a looming "Max Q" event for the stock: the expiration of lock-up periods. While Musk and key insiders are restricted from selling for 366 days, other pre-IPO investors face a staggered 180-day lock-up. When these successive tranches of stock flood the public market, the increased supply could exert immense downward pressure on the share price.[3][7]

Corporate governance has also emerged as a flashpoint. SpaceX listed as a controlled company, utilizing a dual-class share structure that grants Musk approximately 85% of the shareholder voting power. He concurrently holds the titles of CEO, CTO, and Chairman.[2][4][7]

This unprecedented concentration of power has drawn scrutiny from lawmakers. Senator Elizabeth Warren has publicly called for an SEC review of the IPO, arguing that the governance structure leaves traditional investors with significantly fewer rights and demanding greater transparency regarding the company's valuation metrics.[2]

Nevertheless, the sheer gravity of the SpaceX listing has fundamentally reshaped the financial landscape. Retail brokerages reported record-breaking order flows, with individual investors requesting more than $70 billion in shares prior to the debut.[2]

As the 15-day countdown to Nasdaq-100 inclusion ticks away, Wall Street remains transfixed by the SPCX ticker. Whether the stock stabilizes at its trillion-dollar valuation or faces a harsh atmospheric reentry, the SpaceX IPO has already secured its legacy as the defining financial event of the decade.[1][6]
