BlackRock has discussed investing $5 billion to $10 billion in SpaceX’s initial public offering next month, people familiar with the matter said. The massive order, for an offering that could raise as much as $75 billion, would represent a vote of confidence in Elon Musk’s company from the world’s largest asset manager.

The investment would highlight the close relationship between Musk and BlackRock CEO Larry Fink, both of whom traveled to China with President Donald Trump in recent days. The investment would also reflect a growing Wall Street consensus to participate in the largest IPO in history even while SpaceX is seeking a stratospheric valuation and planning to give investors almost no ability to challenge management decisions.
