Nine major Wall Street firms reduced their exposure to spot Bitcoin ETFs by 68,000 BTC between September 2025 and June 2026, according to Galaxy Research. At the same time, sovereign wealth funds and wealth managers absorbed those sales by quietly building up their positions. This structural rebalancing of Bitcoin ETF ownership is redefining who actually holds the world’s leading crypto asset — and why.

Wall Street Trims Exposure: Cash-and-Carry to Blame

SEC-reporting institutions held approximately 355,000 BTC-equivalent in spot Bitcoin ETFs at the end of September 2025. By June 2026, that figure had dropped to 307,000 BTC — a decline of 14%. Nine firms — including Goldman Sachs, Millennium Management, Brevan Howard, and Tudor Investment — account for 68,000 BTC of that reduction on their own, actually exceeding the overall decline of 48,000 BTC.

The primary reason is not a bearish signal on Bitcoin. These players were running a cash-and-carry trade: buying spot ETFs while simultaneously shorting Bitcoin futures to capture the spread. The problem is that the annualized front-month futures premium fell from 7.9% before the October 2025 peak to just 4.8% in the 30 days leading up to October 21, 2026. With short-term US Treasuries offering comparable yields, the trade no longer justifies its structural costs.

This is not a retracement in institutional conviction on Bitcoin — it is the unwinding of an arbitrage strategy that has simply stopped being profitable. That distinction is fundamental to correctly interpreting these flows.

Sovereign Funds and Wealth Managers: The Quiet Accumulation

While hedge funds were unwinding their positions, long-horizon institutions seized the opportunity. Sovereign wealth funds and wealth managers collectively added 20,000 BTC through spot ETFs, partially offsetting the outflows from arbitrageurs. This accumulation reflects a fundamentally different conviction: Bitcoin as a store of value to be held through volatility, not as a vehicle for relative returns.

This type of investor — patient, largely indifferent to spread fluctuations — provides structural support for Bitcoin ETFs. Unlike hedge funds that adjust positions based on futures premiums, sovereign wealth funds operate on multi-year allocation cycles. Their gradual entry into spot ETFs signals a second-wave institutionalization — one that is deeper and more durable.

For the market, this shift in ownership toward stronger hands mechanically reduces potential selling pressure during future correction episodes. A rally underpinned by this type of shareholder base has historically shown a more solid structure than a bull run driven purely by short-term arbitrage strategies.

What’s the Next Key Level to Watch for Bitcoin?

The reshaping of Bitcoin ETF ownership sends a broadly positive underlying signal. With arbitrageurs having exited the market due to insufficient spread, their absence also reduces the mechanical selling pressure that comes with unwinding hedged positions. Indicators such as the RSI and MACD on weekly timeframes deserve close attention to identify a potential breakout beyond key resistance levels.

The bullish scenario hinges on continued accumulation by sovereign wealth funds, which are treating every retracement as an entry opportunity. If the Bitcoin futures premium stabilizes or moves higher, new arbitrageurs could return, amplifying demand for spot ETFs and creating the conditions for a test of previous ATHs.

The bearish risk would lie in institutional redemptions spreading beyond arbitrageurs alone, or in a macro deterioration forcing sovereign funds to cut their exposure to risk assets. In that scenario, the support levels formed by recent accumulation zones would become the first floors to defend in order to prevent a deeper correction.
