Buffett has disclosed that he intends to add about 15 billion dollar's worth of his block of brkb shares into the float annually for 8-10 years, volume permitting. Buffett and Greg deciding that brkb is now a great buy at 1.4 ish xs BV, with Munger gone and Buffett deep into extra innings, is, interesting, to be kind. Obviously, this aggressive buying will help to absorb the increase in float from Buffett selling, BUT, are remaining shareholders getting great value buying now at this valuation, in Gregs first year? When Buffett and Munger were in their prime, they wouldn't pay more than 1.2 xs BV, now, it's worth substantially more? This makes sense to old timers?

Anyway, the story of spcx with respect to how they structured the deal, the small float at the time of the IPO offering, the flood of shares, freeing up, so soon, is a great example of this critical issue. It's remarkable how well the market has been able to absorb all the inside selling in spcx.

), rewrote Wall Street's record books. The company's initial public offering (IPO) raised $85.7 billion, including the underwriters' overallotment, nearly tripling the $29.4 billion raised by Saudi Aramco's IPO in December 2019.

SpaceX was also the catalyst that led committees to rewrite the rules governing index inclusion. Shortly after its debut, it was fast-tracked into the Nasdaq-100, Russell 1000, and Russell 3000.

But Musk's company is making stock market history in dubious ways, as well.

More insider shares are becoming eligible for sale
Traditionally, when a private company goes public, it establishes a share-unlock schedule that prevents insiders from selling for the first 180 calendar days and taking advantage of retail investor euphoria. "Insiders" are high-ranking executives, board members, and early investors who may possess non-public information.

SpaceX flouted convention throughout the IPO process, including with its share lockup schedule. Although CEO Elon Musk is prohibited from selling any of his shares for 366 calendar days, a sizable percentage of early-release-eligible shares can be sold to retail investors well before the 180-calendar-day mark.

Great look at the SpaceX shares unlock schedule as well as the potential passive buying schedule from @JSeyff @FrancisSharoon Depending on the early post-IPO returns, this could really play with and disperse the returns of "passive" funds (which is why there's arguably no such... pic.twitter.com/KOuEkJlngF
