Ripple CEO Brad Garlinghouse says the stablecoin market could surge to $1 to $2 trillion in the next few years. Speaking on CNBC, Garlinghouse highlighted the current $250 billion market cap and noted the rapid growth in demand. Ripple recently entered the stablecoin space with RLUSD, which has already reached $500 million in market capitalization.

Garlinghouse confirmed BNY Mellon will act as custodian for RLUSD, signaling Ripple’s strong institutional focus. He emphasized that regulatory compliance and enterprise support will fuel the next phase of growth. Ripple has also applied for a U.S. banking license and a Federal Reserve Master Account, aiming to bridge the gap between traditional finance and crypto.

Experts agree with Garlinghouse’s forecast. Henrik Andersson of Apollo Capital said stablecoins are being launched by fintechs, banks, and retailers. He believes the upcoming GENIUS Act will further legitimize stablecoins as legal tender. XRP also hit a seven-week high as Ripple’s integration with Transak boosts stablecoin adoption.
