• SpaceX's IPO is the largest in history, valued at $1.77 trillion.
• The company will sell 555.5 million shares at $135 each.
• History suggests that many IPOs struggle after initial enthusiasm.
• SpaceX may be added to major indexes quickly, potentially propping up the stock.

The SpaceX IPO may indicate a shift in investor enthusiasm towards space equities, but its success is not guaranteed. The company's inclusion in major indexes could suggest a strong market presence, which may benefit the stock in the long term, but could also lead to increased volatility.
