Investment Advisors Lead Spot Bitcoin ETF Holdings, Ether ETF Interest Grows

Recent SEC 13F filings reveal that investment advisors have become the dominant holders of U.S. spot Bitcoin ETFs, signaling accelerating adoption of crypto in traditional finance. Advisors now hold over $10.28 billion in BTC ETFs — approximately 124,753 BTC — making up nearly half of all institutional assets in these products.

Hedge funds follow with $6.9 billion (around 83,934 BTC), with brokerages and holding companies trailing behind. Bloomberg ETF analyst Eric Balchunas notes that advisors are now "number one by a mile" in institutional participation. He expects 13F filers — which currently account for around 20% of total Bitcoin ETF assets — to grow to 35–40% as demand from traditional financial firms increases.

Meanwhile, Ether (ETH) ETFs are also gaining traction. Investment advisors hold $582 million worth of ETH exposure (320,089 ETH), while hedge funds have allocated $244 million (134,469 ETH), according to Bloomberg analyst James Seyffart.

The total institutional exposure to Ether ETFs has surpassed $1.06 billion (587,348 ETH). Although still behind Bitcoin in scale, the growing interest shows a shift toward broader institutional adoption of crypto beyond BTC alone.
