SpaceX has surpassed Microsoft, becoming the fourth most valuable public company, following a record IPO and significant shifts in market cap.

#What Does SpaceX Accomplishing the Fourth Spot Mean for Investors?

SpaceX recently surpassed Microsoft to become the fourth most valuable publicly traded company in the world. This significant achievement occurred on June 16, following the company's record-breaking initial public offering just a few days earlier. At the time of this transition, Microsoft’s market capitalization was estimated between $2.92 trillion and $2.97 trillion, while SpaceX's market cap surged toward the $2.8 trillion to $3 trillion range, reflecting a remarkable post-IPO rally.

#How Did the Record-Setting IPO Happen?

The IPO on June 12 was a historic moment for SpaceX, raising an astounding $75 billion by initially pricing shares at $135. This pricing resulted in a first-day valuation ranging from $1.75 trillion to $2.1 trillion. During the initial trading sessions, shares jumped by over 19%, pushing their price into the $200 to $220 range. However, it's important to note that SpaceX's public float remains limited, with about 5% of total shares available to the market.

#Why Should Crypto Investors Take Note?

SpaceX holds approximately 18,700 Bitcoin, valued at around $1.2 to $1.4 billion, placing the company among the upper echelon of public companies with such assets. This Bitcoin exposure signifies that SpaceX’s balance sheet is somewhat tied to Bitcoin's price fluctuations. Following the IPO, Dogecoin has also seen short-term rallies of about 7.6%, closely following news and developments related to SpaceX and Elon Musk.

In early 2026, SpaceX announced a merger with xAI, Musk’s artificial intelligence venture. This deal valued the joint entity at about $1 trillion, further enhancing the financial landscape for investors. Moreover, this combination has pushed Elon Musk's total net worth beyond the $1 trillion mark.

#What Should Investors Be Aware Of Moving Forward?

The tight float of 5% means that a lockup period expiration could lead to insiders selling shares, potentially putting downward pressure on the stock price. The surge of retail trading has already been a crucial factor in the post-IPO climb, but with the company still experiencing operational losses, any disappointing earnings could lead to a market correction. Additionally, SpaceX’s Bitcoin holdings mean its financial performance can be affected by the cryptocurrency market, while the company's ventures in satellite internet services, space launches, and AI development position it firmly in rapidly growing sectors.

As a potential investor, you should monitor the company's financial disclosures and the broader market movements, especially regarding cryptocurrencies and tech stocks, for strategic insight.
