How can retail investors buy shares in SpaceX's IPO?

SpaceX's IPO, targeting a $1.75 trillion valuation, earmarks up to 30% or $22.5 billion in shares for retail investors. Brokerages like Fidelity lowered eligibility from $500,000 to $2,000. Investors need an eligible brokerage account, meet minimum funding, and submit an indication of interest. Flipping shares within two to four weeks may restrict future IPO access.
