BlackRock has filed for a new bitcoin exchange-traded fund which, if approved, would cap investors’ upside while limiting their losses. 

The iShares Bitcoin Managed Protection ETF, or PBIT, would aim “to create and manage bitcoin exposure,” according to a Monday filing with the Securities and Exchange Commission. 

It would work buying options and fixed-income strategies to give investors regulated bitcoin exposure with capped upside and some downside protection — but not direct bitcoin ownership. 

The fund would suit investors who want to invest in bitcoin but not experience all the volatility that comes with the top cryptocurrency. 

Bitcoin has attracted attention for its wild price swings over the years but its volatility has dampened as more investors have bought into the space. 

But 2025 was the least volatile year for the asset and the bear market of 2026 has been its most shallow on record: in past cycles, bitcoin’s price has dropped as low as 80% from its all-time high; this year it shed just 50% of its value. 

BlackRock’s iShares Bitcoin Trust — IBIT — started trading in 2024 after the SEC gave the green light to 11 spot bitcoin ETFs. 

The most successful of the ETFs in terms of flows, the investment vehicle has helped bring bitcoin to Wall Street. Now traders, institutions and retail investors can quickly buy shares that track the price of the leading cryptocurrency. 

They don’t need to worry about exchanges or storage of the digital coin, rather, BlackRock buys and holds the bitcoin while investors simply hit the buy or sell button via their brokerage account. 

IBIT has the most assets under management out of the bitcoin ETFs, currently handling $65.7 billion. 

On Monday, the fund received $665.2 million in fresh investment as bitcoin buyers flooded back into the market. 

That’s the biggest number of shares bought in the product since October 2025, when bitcoin notched a new all-time high, according to Farside Investors data.
