SpaceX's Record $75 Billion IPO: What the Numbers Tell Us

SpaceX raised $75 billion in its initial public offering — the largest ever recorded. The company priced 555.56 million Class A shares at $135 each, giving it a total market value of approximately $1.77 trillion based on that offer price, according to Reuters.

The offering was announced on June 4, 2026, and shares began trading on the Nasdaq Global Select Market and Nasdaq Texas under the ticker SPCX on June 12, per the company's pricing announcement. On the first day of trading, the stock closed at roughly $161 — about 19% higher than the offer price — which pushed the company's market value to approximately $2.1 trillion, DW reported. The stock continued climbing into the following Monday, its first full trading session, according to CNBC. By June 16, SpaceX's market value had briefly surpassed both Amazon and Microsoft, per Reuters.

What the Business Numbers Show

SpaceX's revenue tells an important part of the story. The company brought in $18.7 billion in total revenue during 2025, up from $14.1 billion in 2024 — a 33% increase year over year — according to Reuters. At the $135 offer price, investors were effectively paying roughly 95 times the company's annual revenue for each dollar of sales. (This ratio is called the price-to-sales multiple; it measures how expensive a stock looks relative to the money it actually brings in.) When the stock jumped to $161 on the first day, that multiple stretched to around 112 times revenue.

For comparison, Nvidia — often held up as an example of a pricey but legitimate growth stock — traded at roughly 25–30 times revenue at its 2024 peak. The gap between SpaceX's multiple and Nvidia's is substantial, and it reflects several factors working together. First, investors are betting on the size of Starlink's potential market — a global broadband network that SpaceX owns. Second, they are pricing in steady demand from government and commercial clients for Falcon 9 and Starship launch services. Third, the market may be charging a premium simply because SpaceX was, until now, available only to a small group of institutional investors and people trading on the secondary market. Scarcity itself can push a stock's price higher.

Size and Structure

At $75 billion in fresh capital from 555.56 million shares, this deal is roughly three times larger than the previous record — Saudi Aramco's $25.6 billion IPO in 2019. Those 555.56 million shares represent only about 4.2% of SpaceX's total shares outstanding. A thin float — the shares actually available for public trading — can create practical challenges: prices may be harder to discover accurately early on, and large buy or sell orders may cause bigger swings than you'd see with companies that have more shares in public hands.

One structural detail worth noting: SpaceX is listing on two Nasdaq venues at once — the main Nasdaq Global Select Market and Nasdaq Texas, a newer exchange that started operating under a Texas state charter in 2025. This dual listing suggests the company is spreading risk across two separate exchange relationships. Given SpaceX's complex regulatory position — it deals with federal agencies on launches, satellites, and defense contracts — diversifying exchange exposure makes practical sense.

Reading the First Day's Moves

A 19% jump on the first day of trading for a $75 billion offering is not routine. At this scale, the trading is dominated by large institutional investors, not retail buyers checking their phones. The fact that the stock kept climbing through the first full trading session on Monday points to genuine buying interest beyond one day's initial excitement.

What this first-day move actually means is harder to pin down. Investors could be making a real judgment about SpaceX's long-term value. Alternatively, the thin float — only 4.2% of shares in public hands — might simply be creating an upward squeeze on price as demand collides with limited supply. Both could be true at once.

The revenue growth SpaceX has shown — jumping from $14.1 billion to $18.7 billion in a single year — gives bulls a concrete fact to point to. But the valuation the market has placed on the stock demands that SpaceX sustain that kind of growth for many years, and also improve its margins — the profit it keeps after paying its bills. For now, the market is betting on the company's options: what it might earn from fully commercializing the Starship rocket, expanding Starlink's global reach, and winning defense contracts. Whether investors remain comfortable with that bet when SpaceX reports its first results as a public company will be the next real test.

What Comes Next

SpaceX is now, by market value, one of the three or four largest companies in the world. That has mechanical consequences. Index funds that track the broader market will be forced to buy SpaceX shares to match their benchmarks. Money allocated to aerospace and defense will get recalibrated. The process of rebalancing — funds shuffling portfolios to match new weightings — will unfold over the coming weeks and likely keep some upward pressure on the stock.
