Elon Musk’s rocket company said it would sell more than 555 million shares at $135 each in its blockbuster initial public offering, which is set to begin trading on Friday.

Two Times tech reporters and their editor talk about assessing the sky-high valuation of the rocket and satellite maker, the potential economic impact of its public debut and the role of the world’s richest man in it all.

Elon Musk’s rocket company is spending big and losing money. That has raised questions about whether it can justify its valuation for its blockbuster initial public offering.

Investors who bought the automaker’s shares in its initial public offering became rich. As a result, many have a deep faith in Elon Musk, the chief executive of Tesla and SpaceX.

Wall Street is giving its richest clients velvet rope access to this week’s public listing of SpaceX, reflecting the growing importance of the wealth management business.

Elon Musk’s rocket company, on the cusp of the largest initial public offering ever, will soon end up in index funds after rule changes by Nasdaq and other index providers.

The $135 share price means Elon Musk’s rocket maker is poised to exceed the 2019 initial public offering of Saudi Aramco in both valuation and money raised.

The ways it set up its board and Mr. Musk’s pay appear to benefit him at the expense of other shareholders, corporate governance experts said.
