X Launches Cashtag Trade Button in US With Interactive Brokers, Coinbase, Kraken, Gemini, Moomoo

X is effectively converting its cashtag chatter into a broker-agnostic routing layer, letting multiple regulated venues compete for clicks rather than owning the order flow itself. That matters for brokers seeking low-cost retail acquisition and for crypto platforms like Coinbase, Kraken and Gemini now sitting alongside equities in the same discovery feed. The open question is whether a social trigger produces durable engagement or just a spike, as the cited April testing volume hints at a burst rather than a baseline.
