Because A shares have more voting rights, and because these rights have some value, they often trade at a slight premium. In reality, GOOG and GOOGL often trade for just around the same price. For example, on Aug. 1, 2022, GOOG shares opened at around $115.53 and GOOGL at $115.30. Sometimes, one share class will trade at a relative premium to the other, but due to arbitrage opportunities, these spreads will often close over time.
