SpaceX IPO Looms as Secondary Market Booms

The potential for a SpaceX initial public offering in 2026 is generating significant buzz, with reports indicating the company is engaging major Wall Street banks. This move is viewed by many as a potential catalyst to reinvigorate the stagnant market for new stock listings. While the public waits, a robust secondary market for shares in late-stage private companies like SpaceX is providing crucial liquidity for employees and early investors, offering a glimpse into the valuation and demand for these pre-IPO giants.

Greg Martin, founder and managing director of Rainmaker Securities, a firm specializing in secondary transactions for private companies, sheds light on this dynamic landscape. He notes that the prolonged IPO drought has fundamentally changed the game. “Private companies are staying private much longer now,” Martin observes. Many businesses, including those that would rank among the S&P 500’s largest, historically would have gone public years ago. This delay has created a powerful convergence: investors crave access to these economic engines, while long-tenured shareholders seek to unlock value from holdings that often constitute a major portion of their wealth. These twin forces have fueled a thriving secondary market, a trend Martin expects to continue as more market capitalization resides in private hands.

Even if a landmark IPO like SpaceX’s occurs, Martin doesn’t foresee a slowdown in secondary activity. While such an event would shift massive value into the public markets, it could simultaneously increase overall interest and capital flow into the private sector. “When we see the matriculation of SpaceX to the public markets, I think it’s going to actually increase capital market interest in private companies,” he suggests, pointing to the rapid ascent of firms like OpenAI and Anthropic as evidence of the immense value being created outside of public exchanges.

Regarding SpaceX specifically, Martin identifies it as the bellwether many are watching. “The markets are really waiting for a bellwether company… and there’s a huge amount of interest,” he states. A successful SpaceX debut could reset the entire IPO environment. Interest on Rainmaker’s platform remains intense, with SpaceX shares consistently pricing upward, even during broader market downturns, and currently trading above its last tender offer valuation.

The shift in Elon Musk’s stance on taking SpaceX public, famously tied to regular Mars missions, reflects current realities. Martin points to favorable market conditions, SpaceX’s dominant position in launch services and its growing Starlink business, and the sheer scale of its ambitions, from Starship to potential space-based data centers. Accessing the full breadth of the capital markets could fuel these ventures. An IPO would likely involve a small percentage of shares initially, bringing transparency to its shareholder base. While this may reveal economic interests from various global entities, Martin believes Musk and a core group will retain control.

The competitive landscape adds urgency, with rivals like Jeff Bezos’s Blue Origin and Sam Altman’s OpenAI pursuing their own massive funding and strategic goals. However, Martin believes SpaceX operates from a position of strength. “They can find the right time when the market presents itself well, because they have a business that is largely profitable, and they have dominance in their two key businesses. So they’re in the driver’s seat.”

Pricing the IPO will involve balancing financial fundamentals with the undeniable “Elon halo effect.” Martin anticipates a premium valuation, as investors buy into the long-term vision. “People believe in the future of a data center in space… it sounds crazy, just like going to Mars sounds crazy. But if anyone can do it, Elon’s probably the guy.” This faith, however, introduces risk for investors uncomfortable with valuations heavily weighted on future promises versus present balance sheets.

For employees and early shareholders, liquidity before an IPO varies. SpaceX maintains tight control over its capitalization table but facilitates regular tender offers. A significant portion of secondary trading occurs through special purpose vehicles (SPVs), where economic ownership changes without altering the official cap table. Firms like Rainmaker navigate these complex structures to provide liquidity while respecting company rules.

Access to information remains a key challenge in private markets. While some companies provide data rooms to facilitate informed trading, others are more guarded. “The more information we can provide, the lower the risk for investors, and that tends to open up markets,” Martin explains. Sophisticated investors seek the same due diligence, financials, management, cap table details, as they would for a public company, making well-known entities like SpaceX more attractive despite limited disclosure.

Beyond SpaceX, Martin notes strong secondary demand for other late-stage leaders like Databricks, Stripe, ByteDance, and AI-focused companies such as OpenAI, Anthropic, and Cohere. As firms like Discord or Canva signal public listing plans, secondary activity typically increases in anticipation. “As the IPO market starts to open up, we’re going to see that broaden,” Martin predicts, highlighting that 2023 was Rainmaker’s biggest year, with over $1 billion in secondary transactions.

The growing secondary market serves a vital function, according to Martin. It provides essential price discovery long before a company files for an IPO. By opening up secondary trading, companies can gauge investor demand, build a broader shareholder base, and ultimately achieve a more efficient and stable public debut. A chaotic first-day pop, like Figma’s 200% surge, often indicates poor pre-IPO price discovery. In contrast, a robust secondary market helps align expectations, smoothing the path from private valuation to public market success.
