X's Cashtag Partner Program Brings Brokers into the Fold

X's redesigned Cashtag experience has already driven an estimated $1 billion in global trading volume after just three days, according to X's own estimate. This figure is not independently audited but provides useful context for the new partner program.

The Cashtag Partner Program allows users to open a supported stock, ETF or cryptocurrency ticker, view its price chart and related posts, and then select a trading provider. Execution remains outside of X, on the partner's app or website.

This distinction changes the economics of the product, as X doesn't need to become a brokerage to participate in the trading funnel. It already occupies something brokers spend heavily to acquire: the investor's attention immediately before a potential trade.

The five launch partners - Interactive Brokers, Moomoo, Coinbase, Kraken, and Gemini - are competing for users once they decide to act. X sits above them as the discovery interface rather than underneath them as the execution infrastructure.
