SpaceX Surges Past Amazon as Shares Rally Following Record IPO

Elon Musk’s SpaceX is maintaining its meteoric momentum, poised for a fourth consecutive day of gains following its historic initial public offering. The rocket and AI powerhouse has officially overtaken Amazon.com Inc. in market value, cementing its status as a dominant force in the global equity markets.

A Historic Leap in Market Valuation

The rally in Space Exploration Technologies Corp. (SpaceX) has been nothing short of extraordinary. Since its debut, the stock has rallied approximately 49%, a surge that has propelled the company to become the fifth-largest stock in the world. This rapid ascent has seen SpaceX surpass the market capitalization of Amazon, leaving it roughly $150 billion behind Microsoft Corp.

In Wednesday's premarket trading in New York, SpaceX shares rose by 4.5%. While this indicates a slightly slower pace of growth compared to the explosive gains of previous sessions, the upward trend confirms sustained investor demand. This high appetite for SpaceX shares provides a crucial litmus test for the market's ability to absorb massive IPOs, particularly as industry heavyweights like OpenAI and Anthropic are expected to seek public listings with potential $1 trillion valuations later this year.

Supply Dynamics and the "Low Float" Factor

One significant driver behind the stock's volatility and rapid price appreciation is the "low float" nature of the offering. On its first day of trading, only about 4.2% of SpaceX's total stock was made available to the public. This scarcity, combined with the fact that 30% of the initial issue was specifically allocated to retail investors, has helped drive prices higher.

However, market analysts warn of potential headwinds. As insider lockup periods expire in the coming months, the sudden influx of shares available for sale could exert downward pressure on the stock price. Investors will be closely watching whether the current demand can offset this potential increase in supply.

The Impact of Index Inclusion and Rule Changes

Trajektori masa depan saham SpaceX mungkin akan sangat dipengaruhi oleh aturan inklusi indeks. Nasdaq Inc. baru-baru ini memperbarui regulasinya untuk memungkinkan perusahaan berskala besar seperti SpaceX masuk ke dalam indeksnya dengan lebih cepat. Perubahan ini dapat memicu "pembelian paksa" dari dana institusional yang melacak indeks seperti Nasdaq 100, yang memberikan dorongan signifikan bagi harga saham.

Sebaliknya, S&P Dow Jones Indices memilih untuk tidak mengubah aturannya guna memungkinkan IPO baru masuk lebih cepat, yang berarti SpaceX tidak akan langsung masuk ke dalam S&P 500. Perbedaan ini menciptakan lanskap yang kompleks bagi investor; sementara beberapa pihak mungkin menunggu instrumen pelacak indeks pasif untuk mendapatkan eksposur, yang lain bergerak agresif untuk menangkap momentum saat ini.
