Investors in BlackRock's iShares Bitcoin Trust ETF (IBIT) are now down about 40% on average, according to Bespoke Investment Group, following a week ending Friday, June 26 that saw U.S. spot Bitcoin ETFs bleed $1.79 billion. The losses stem from Bitcoin's sustained selloff after the October 2025 flash crash and a more hawkish Federal Reserve stance. As recently as mid-2025, the average IBIT holder was up roughly 30%, per Bespoke data cited by Bloomberg, but the crypto downturn has erased those gains and pushed typical positions deep underwater. The 2024 regulatory approval of spot Bitcoin ETFs marked a milestone for mainstream crypto access, yet BlackRock's flagship product now holds $44.42 billion in net assets against $60.77 billion in total inflows since launch — a roughly $16 billion gap driven by Bitcoin's price decline.
IBIT Investors Record 40% Average Loss
The typical investor in BlackRock's IBIT is now down about 40%, according to Bespoke Investment Group. This figure measures the average buyer's entry price against Bitcoin's current level, reflecting how far underwater the typical position sits. Those are paper losses until investors actually sell.
Nate Geraci of NovaDius Wealth Management called it "a brutal intro to btc for mainstream investors." Bespoke analysts were blunt, stating that "those assets are hurting" and describing the funds so far as an "absolute disaster for investors." They also noted that a fresh rally could still rewrite the story.
The damage shows in the fund itself. IBIT has pulled in $60.77 billion since launch but holds just $44.42 billion in net assets, per SoSoValue. That's roughly a $16 billion gap, driven largely by Bitcoin's price drop.
U.S. Spot Bitcoin ETFs Post $1.79 Billion Weekly Outflow
U.S. spot Bitcoin ETFs bled about $1.79 billion in the week ending Friday, June 26. This is their heaviest weekly outflow since launch, trailing only late February 2025's $2.61 billion exodus.
Friday's $444.51 million outflow came entirely from IBIT, extending the daily losing streak to seven sessions. It was also the funds' seventh straight negative week, the longest such run on record.
The selling has coincided with a more hawkish Federal Reserve, which held rates on June 18 and cut its easing language. Higher rates tend to pull money out of risky bets like crypto. Traders now see better-than-even odds of a December rate hike.
At press time, Bitcoin was trading near $60,423, after climbing 1.1% in the past 24 hours.
