U.S. spot XRP exchange-traded funds (ETFs) kept up the positive momentum for a twelfth consecutive day, with their net inflows totalling $844.9 million as of Dec. 2, according to data tracked by SoSo.

The sustained accumulation of capital by spot XRP ETFs established them as the fastest-growing class of major crypto-asset vehicle. The funds are closing in on the $1 billion milestone in assets and signaling a significant expansion of regulated crypto exposure beyond bitcoin BTC$92,900.39 and ether ETH$3,079.69.

The XRP ETFs saw a total net inflow of $67.7 million bringing their cumulative total inflow to $844.9 million since they debuted on Nov. 13, the SoSo data shows. On Monday, the products drew $89.65 million, making it one of its strongest sessions since inception.

The trend makes spot XRP the fastest growing ETF class and places it near the $1 billion asset milestone, a level analysts say is key for long-term institutional adoption.

Wall Street investment firms, including Fidelity, Invesco and Franklin Templeton, also filed to list spot XRP ETFs, according to Depository Trust and Clearing Corporation (DTCC).

“Congrats to $XRPC for $58 million in day one volume, the most of any ETF launched this year,” said Eric Balchunas, senior Bloomberg ETF analyst on X.

While the XRP products demonstrate impressive momentum, they operate within an increasingly active crypto ETF landscape. Spot Solana ETFs saw a significant rebound after a red day of $13.5 million in redemptions with an inflow of $45.7 million and as of yesterday stood at $651 million in cumulative net inflows.

The much larger spot bitcoin ETFs remain mostly unmoved at $57.7 billion, while their ether equivalents sit at just over $12.8 billion, according to Farside data.
