Big Tech stablecoin refers to a digital currency created or backed by a major technology company, such as Meta (formerly Facebook), Google, or Amazon. Unlike regular cryptocurrencies that can have wild price swings, stablecoins are designed to stay steady in value, usually tied to a currency like the US dollar. Big Tech firms entering this space could make stablecoins more widely used for payments, shopping, and sending money globally—right from apps people already use every day. However, these projects raise concerns around privacy, data control, and financial power being concentrated in the hands of a few companies. Governments and regulators around the world are watching closely, as Big Tech stablecoins could reshape the global financial system in big ways.
