X has begun rolling out its U.S. Cashtag Partner Program, linking supported stock, ETF and cryptocurrency ticker pages to Coinbase, Kraken, Gemini, Interactive Brokers and Moomoo. The September 15 announcement adds a Trade button to eligible Cashtags, allowing users to move from price charts and market discussion to a partner's app or website to register, research an asset or place an order. X does not execute transactions itself. The company said a pilot generated roughly $1 billion in global trading volume during its first three days, while leaving undisclosed revenue-sharing arrangements, supported-asset limits and plans for expansion outside the United States. The program builds on X's earlier price-tracking and smart Cashtag features and represents its most direct move toward connecting its finance and crypto conversations with regulated trading venues.
