SpaceX Eyes $1.75 Trillion IPO Filing in March, Reshaping Pre-IPO Secondary Pricing

SpaceX Moves Toward Historic IPO at $1.75 Trillion Valuation Elon Musk's SpaceX is preparing to file confidential IPO paperwork with the U.S. Securities and Exchange Commission as early as March 2026, targeting a valuation exceeding $1.75 trillion — a figure that would eclipse most S&P 500 companies and surpass even Tesla. Sources indicate the company is eyeing a public listing around June 2026. xAI Merger Supercharges Valuation The anticipated valuation reflects a February 2026 organizational integration with xAI, Musk's artificial intelligence venture, in a deal that valued the combined entity at $1.25 trillion. The merged structure encompasses Grok (AI chatbot and voice features), Imagine (video generation), coding tools, and the enterprise-focused MacroHard division. The AI angle has materially boosted SpaceX's secondary market premium. Key Data Points Target IPO valuation: $1.75 trillion+ Potential capital raise: up to $50 billion Combined SpaceX + xAI entity valued at $1.25 trillion (February merger) Expected public listing window: June 2026 Filing: Confidential with the SEC, allowing strategy refinement away from public scrutiny Secondary Market Context SpaceX has long been one of the most actively traded names in private secondary markets. Its secondary shares have historically traded at premiums to the last tender offer price, driven by high demand and scarce supply. A confidential IPO filing materially narrows the time horizon to liquidity, which typically compresses the discount demanded by secondary buyers — and in SpaceX's case, could drive pricing above last-round marks. Why This Matters for Private Markets A SpaceX IPO at $1.75 trillion would be the largest public debut in history, unlocking significant liquidity for secondary holders and early investors. The filing signals that the long-anticipated wave of mega-unicorn IPOs in 2026 — including OpenAI and Anthropic — may be accelerating. For secondary market participants, the shrinking pre-IPO window creates both urgency and upward pricing pressure on SpaceX secondary positions. GPs holding SpaceX exposure through continuation vehicles should expect LP secondary bids to tighten materially in coming weeks.
