The answer, in one paragraph

Musk received 1 billion performance-based restricted Class B shares before the IPO, tying a substantial award to market-cap milestones. Institutional investors then asked SpaceX to reconsider its proposed IPO governance provisions. Meanwhile, the IPO and full underwriters' option sold 638.9 million Class A shares, the first lockup release made more than 911 million shares tradable, and a later tranche made up to 328.4 million more shares eligible for sale. Musk reported beneficial ownership of about 6.42 billion Class-A-equivalent shares, leaving the scale of his position central to the governance debate as the float expanded.
