SpaceX has moved up its employee share vesting schedule from May to as early as next week, signaling preparations for what could be the largest IPO in history. The company is targeting a valuation exceeding $2 trillion with potential fundraising of up to $75 billion, according to sources familiar with the matter.

The accelerated vesting addresses employee concerns about share liquidity when the company goes public. SpaceX is expected to file its IPO paperwork later in May and set pricing the week of June 15, sources said. This timing coincides with Elon Musk's efforts to rebuild xAI, which SpaceX acquired earlier this year.

Strong demand for SpaceX shares could create substantial wealth for existing shareholders. Alphabet Inc. stands to potentially gain $100 billion from its early investment. SpaceX might enter the Nasdaq 100 quickly after its debut, driving further demand as index funds adjust their positions.
