A listing is when a CEX or DEX begins markets for a token, improving access and liquidity.
Major CEX listings are classic attention catalysts. Price can rise into the event and fade after.
In research workflows, Exchange listing is usually interpreted with Delisting, Liquidity, Centralized exchange, and Catalyst rather than as a standalone signal. Compare circulating float, unlock overhang, and where size can actually trade before trusting a breakout headline.
