Institutional investment managers increased their allocations to U.S. Bitcoin exchange-traded funds (ETFs) in the fourth quarter of 2025, even as the asset suffered a sharp price correction that reduced its market value by almost a quarter.
The divergence between rising stock numbers and falling asset values presents a complex picture of institutional behavior in a period of extreme volatility.
According to data from CryptoSlate, Bitcoin price started the last three months of last year on strong footing and reached a new all-time high of more than $126,000 in October.
However, this rally proved unsustainable and resulted in a turbulent period triggered by a massive $20 billion deleveraging. At the end of the year, Bitcoin was trading below $90,000.
Understanding the Trend
Despite this turbulent backdrop, early regulatory filings suggest that professional money managers viewed the decline as a buying opportunity rather than a reason to exit the market.
At press time, BTC has returned to bullish momentum this year and is aiming for a break above $100,000.
The Mathematics of Accumulation
An early analysis of 13F filings compiled by Bitcoin analyst Sani found that 121 institutions reported a net increase of 892,610 shares of various U.S.-listed spot Bitcoin ETFs from the third quarter to the fourth quarter of 2025.

Paradoxically, while the physical number of shares held by these companies increased, the total dollar value of these holdings fell by approximately $19.2 million.
To understand this dynamic, one must look at the raw totals reported by these companies. As of the third quarter of 2025, the institutions tracked held a total of 5,252,364 shares worth approximately $317.8 million.
By the end of the fourth quarter, their holdings had grown to 6,144,974 shares, but the market value of that larger stack had shrunk to $298.6 million.
BlackRock’s Role
Nowhere is this disconnect between capital flows and asset performance more evident than in the books of the BlackRock iShares Bitcoin Trust (IBIT).
Last year, the fund achieved something incredibly rare in the asset management industry by attracting billions of dollars in new inflows while simultaneously losing money for its clients.
According to data from Bloomberg Intelligence, IBIT ended 2025 as the sixth most popular ETF in the United States by net inflows. It raised $25.4 billion in fresh cash, outperforming established giants such as Invesco QQQ Trust and SPDR Gold Trust (GLD).
Adoption or Arbitrage?
However, there is an interesting caveat to the “institutional adoption” narrative.
Spot Bitcoin ETFs sit at the intersection of long-term investing and short-term arbitrage. An increasing share count in a 13F filing appears to be an optimistic belief, but can often disguise a market-neutral hedge.
On the surface, the adoption story is sound. A December study from State Street estimated the U.S. Bitcoin ETF market at $103 billion, with institutions owning nearly a quarter of that supply. Their data suggests that 60% of institutional investors prefer the regulatory security of an ETF shell over owning physical coins.
