Class C shares carry no vote, which is the substantive difference between them and the Class A stock trading under GOOGL. Both represent claims on the same business: Google Search, YouTube, the Android and Chrome platforms, Google Cloud, and the longer horizon ventures grouped as Other Bets. Control of the company does not rest with either line, since the founders hold Class B shares carrying ten votes each. The two public lines tend to trade close together, and the spread between them says something about how the market prices a vote, not about any difference in the earnings behind the share.
