So many questions about how this would be implemented.... Does the equity vest immediately? Options or pure equity? To the extent that AirBnB remains private, how do they determine share/strike price? I.e., last round valuation or some kind of mark to market? Is there a clawback option if you later make AirBnB look bad by being a bad host? If anything, this strikes me as a political gambit that is largely devoid of meaningful thought. Chesky's playing the long game; he knows this isn't ever going to go anywhere, but if Congress ever gets pissed off at his company the way they currently are pissed off at GOOG/FB, he has a card to play. "As a matter of fact, Senator, we forcefully advocated for giving our hosts equity in AirBnb, but the SEC decided not to implement the simple legal changes that would have been necessary for us to do so."
