The $86bn Listing That Reopened the Window — and the 50% Drawdown That Followed
bIAnk AI Research · September 2026 · 8 min
SpaceX priced the largest IPO in history at $135 a share on 11 June 2026, raising around $86bn at a $1.77trn valuation and lifting Americas IPO proceeds to $194bn in the first half against $62bn a year earlier. By late July the shares were down roughly 50% from their post-listing peak. Both facts matter.
The numbers are without precedent. SpaceX priced at $135 per share on 11 June 2026, raising $75bn at pricing and roughly $86bn including the over-allotment, valuing the company at $1.77 trillion — more than three times Saudi Aramco's 2019 record of $24.9bn. Shares opened at $150 and closed the debut session on 12 June up 19%, briefly taking the market capitalisation past $2 trillion and making Elon Musk, momentarily, the world's first trillionaire.
The aftermarket was less kind. By late July 2026 the shares had fallen roughly 50% from their post-IPO peak and the trillionaire headline had reversed. A listing can be a triumph of execution and a disappointment as an investment at the same time; the two are measured on different clocks and by different parties.
What the deal did do was reopen the global window. EY and Dealogic data put Americas IPO proceeds at $194bn in the first half of 2026 against $62bn in the first half of 2025, of which roughly $86bn came from that single June transaction. Asia-Pacific proceeds jumped to $130bn from $17bn. US new issues above $50m raised around 20% more on average through 30 June, and the second quarter was the highest-proceeds quarter on record. The Renaissance IPO ETF was up about 18% year-to-date as of 24 August.
Strip out the mega-deal and the picture is healthy rather than euphoric: pricing discipline held, allocations were tight and the follow-on calendar filled. That is the environment in which a well-prepared mid-cap can list, and it is why the pipeline conversation moved through the summer to names like Anthropic and the perennial OpenAI speculation.
For private companies the strategic read is about optionality. A credible IPO alternative is the single most effective lever in a trade sale negotiation, and building it takes four to six quarters of audited reporting, board formalisation and KPI consistency — not a decision made when the window opens. The companies that captured 2026's window began preparing during 2024's closure.
The second lesson is about aftermarket discipline. A 50% drawdown on the largest listing in history did not close the market, because the underlying demand was for exposure to a theme rather than to a single security. But it did reset how bankers frame greenshoe sizing, lock-up structures and the float percentage that a story stock can sustain.
Key takeaways
- SpaceX priced at $135 on 11 June 2026: ~$86bn raised at a $1.77trn valuation, the largest IPO ever
- Shares opened at $150 and rose 19% on debut, then fell roughly 50% from the post-IPO peak by late July
- Americas IPO proceeds $194bn in 1H 2026 vs $62bn in 1H 2025; Asia-Pacific $130bn vs $17bn (EY / Dealogic)
- A credible listing alternative requires four to six quarters of preparation — build it before the window opens
