U.S. investors quickly reversed course on Thursday, cashing out over half a billion dollars from spot bitcoin exchange-traded funds as risk-off sentiment surfaced again. 

A total of $635.6 million left the funds on Thursday, data from Farside Investors shows. The redemptions put downward pressure on the price of bitcoin, which dropped under $81,000 at one point. 

The coin has since rebounded and was recently trading for nearly $81,669, down just 1% over a 24-hour period. 

BlackRock’s iShares Bitcoin Trust saw the biggest outflows, with investors cashing out over $254 million. Fidelity’s Wise Origin Bitcoin Fund followed, losing close to $218 million. 

Over $109 million left the ARK 21Shares Bitcoin ETF; Morgan Stanley’s fund and Bitwise’s ETF lost nearly $30 million and over $27 million, respectively. 

But the investment vehicles this week have this week received net positive investment of over $439 million. 

Investors went into “risk-off” mode after flare ups in the Middle East sent the price of oil higher. Brent crude hit its highest price in five months after Yemeni rebel group the Houthis on Thursday attacked Saudi Arabia, sparking concerns over more disruption to energy supplies. 

Bitcoin’s price has been rattled this year since the U.S. and Israel attacked Iran, halting oil supplies as ships have struggled to pass through the strategic Strait of Hormuz, where a fifth of the world’s oil passes through. 

A higher oil price can hurt the price of bitcoin and other “risk-on” assets because it increases the chances of the U.S. central bank raising interest rates. 

Bitcoin has typically done well in a low interest rate environment because it means the asset has more liquidity to rally. 

Investors on Thursday also sold off tech stocks, which had rallied earlier in the week off the back of SpaceX’s impressive earnings. 

Analysts are saying bitcoin is entering a bull market again. Data last month showed that  the leading cryptocurrency crossed above its 365-day moving average — a typical sign it is out of a bear market — following a strong run in August. 

Bitcoin notched a record of $126,080 in October 2025 but then began to sink later that month after the biggest liquidation event in crypto history saw over $19 billion in bets closed. 

The coin spent the first half of 2026 trading well below that level but picked up again in August and September, having its best quarter in years.
