Spot Bitcoin ETFs Record Worst Month as $4 Billion Leaves Institutional Funds

U.S. spot Bitcoin exchange traded funds are heading toward their weakest month since launching in January 2024, with investors pulling out nearly $4.06 billion during June. The monthly outflow has already surpassed the previous record of $3.56 billion, set in February 2025, highlighting a sharp decline in institutional demand for the world’s largest cryptocurrency.

The heavy selling accelerated during the past week alone, when spot Bitcoin ETFs recorded around $1.79 billion in net redemptions. It was the second-largest weekly outflow since these investment products began trading. Final figures could still change slightly before the month officially ends.

Institutional Demand Weakens Despite Early Optimism

Market expectations at the beginning of June pointed to renewed buying interest after SpaceX’s IPO on June 12, but that momentum failed to appear. Instead, institutional investors continued reducing exposure through regulated Bitcoin investment products.

Spot Bitcoin ETFs are widely viewed as a key measure of institutional sentiment because they allow investors to gain exposure to Bitcoin without directly holding the digital asset.

Bitcoin Price Under Pressure as ETF Selling Continues

June followed another difficult month, after ETFs recorded $2.43 billion in net outflows during May. Combined, nearly $6.5 billion has exited these funds over the past two months. Since the start of 2026, total net outflows have reached roughly $5 billion.

The sustained withdrawals have weighed heavily on Bitcoin’s performance. Btc has fallen about 30% during the first half of 2026, while shares of Strategy (MSTR) have dropped roughly 45%, reflecting continued pressure across Bitcoin related investments.
