SpaceX shares continued their extraordinary post-listing climb, trading above $220 in overnight trading on Tuesday, 16 June, pushing the company's market capitalisation to within $100 billion of tech giant Microsoft, according to market commentary platform The Kobeissi Letter. The stock has surged approximately 63% from its IPO price of $135 per share since its market debut on 12 June.
Scale of the Post-IPO Rally
The Kobeissi Letter, in a post on X, described the surge as unprecedented, stating that no initial public offering in history had witnessed a rally of such magnitude in such a compressed timeframe. SpaceX shares settled 19% above the offering price on their Nasdaq debut alone — before the broader rally gathered pace in subsequent sessions.
The company had already set records before trading began, raising $85.7 billion after underwriters exercised the greenshoe overallotment option, making it one of the largest IPO fundraising exercises ever recorded.
SpaceX and Tesla Together Eclipse Apple
The rally has propelled the combined market capitalisation of SpaceX and Tesla to a record $4.4 trillion, according to the platform — a figure that exceeds Apple's total market value and is approaching that of Google. The scale of investor enthusiasm surrounding Elon Musk's business empire is, by this measure, without modern precedent.
Notably, this is not merely a single-stock story. The concurrent strength in Tesla has amplified the combined valuation effect, drawing comparisons to the peak valuations of the world's most valuable companies.
Elon Musk's Net Worth Crosses $1.3 Trillion
The post-IPO surge has had a direct and dramatic impact on Elon Musk's personal fortune. His net worth has surpassed $1.3 trillion, a level reportedly never before reached by any individual. According to The Kobeissi Letter, Musk's wealth now exceeds the market capitalisation of all but 12 publicly listed companies worldwide.
This comes amid a broader moment of concentrated wealth creation in the technology and aerospace sectors, where a handful of founder-led companies have reshaped global capital markets in the span of a few years.
What to Watch Next
Analysts will be watching whether SpaceX can sustain valuations at this level once post-IPO momentum fades and institutional rebalancing begins. The gap with Microsoft — now reportedly under $100 billion — means SpaceX could briefly claim a position among the world's top two or three most valuable companies if the rally holds. Lock-up expiry periods and any earnings guidance from the company will be key near-term catalysts.
Point of View
It raises real questions about market concentration and the pricing of speculative future cash flows — particularly for a space and satellite business whose core revenue model remains opaque to most retail investors. The Kobeissi Letter's framing of this as 'unprecedented' is accurate, but mainstream coverage is underplaying the risk side: a 63% gain in four days creates a base that is almost impossible to sustain without continuous positive catalysts. The gap with Microsoft is a headline, not a floor.
