BlackRock takes a new step with Bitcoin

On 19 October 2026, BlackRock filed documents for a new fund that combines bitcoin exposure with a strategy designed to limit losses. The product is called the iShares Bitcoin Managed Protection ETF and has the proposed ticker PBIT. The filing is not a final launch. Still, it shows BlackRock trying to reach another group of investors: people interested in bitcoin who want less exposure to falling prices.

BlackRock is creating another route into bitcoin

BlackRock is the world’s largest asset manager. According to Reuters, the group managed around 15.49 trillion dollars in assets in the third quarter of 2026. This is money clients have placed with BlackRock through funds and other investment products. It is not cash the company can freely spend itself.

BlackRock’s size makes the new filing relevant. The company does not only sell ordinary index funds. It also builds products for investors who want a specific type of market exposure. The new bitcoin strategy targets investors who want exposure to the cryptocurrency while also seeking some form of protection against losses.

BlackRock already operates a well known spot product, the iShares Bitcoin Trust ETF, ticker IBIT. That fund holds bitcoin and seeks to track its price performance. The new filing takes a different approach. It proposes using options and fixed income investments to shape the fund’s bitcoin exposure.

The new fund seeks to limit losses

According to the filing, the fund seeks to track the value of IBIT or similar bitcoin exposure up to a certain limit. At the same time, it attempts to reduce the impact of declines. The strategy uses a combination of purchased and sold option contracts and investments in fixed income products.

An option is a contract that gives its holder the right to buy or sell an underlying asset under specified terms. Its value depends on factors including the market price, time remaining and market conditions. Options can help protect a portfolio, but they also make the product more complicated.

The fund does not invest directly in bitcoin, according to the filing, and it does not simply hold shares of IBIT. Instead, it uses option structures linked to bitcoin exposure. That is an important difference from a spot product, which holds the cryptocurrency itself.

What does that mean? You would not be buying bitcoin directly through this product. You would be buying an exchange traded fund whose result depends on a strategy using options and other investments. Its performance may therefore differ from bitcoin’s own price movement.

Protection against losses also limits gains

The strategy has a trade off. The fund sells option contracts to help offset some of the cost of options it buys. This also limits how much it can benefit if bitcoin rises. The upside limit depends on market conditions and the option structure.

The protection is also not identical for every investor at every moment. The filing says the protection start value for a tranche is typically around 90 percent of the reference asset’s value when that option position is established. This creates an initial loss exposure of about 10 percent for that tranche, before fees. However, the manager has discretion to adjust positions, and the protection can change as prices move.

This is not a fixed floor under the value of an investment. Protection is part of an investment strategy and may not work in the same way for someone who enters later. The filing warns that investors could lose some or all of their money.

A simple calculation shows the difference

Suppose you invest €1,000 directly in bitcoin and its value then falls by 30 percent. Your holding is worth €700. If the value rises by 30 percent, the same investment becomes €1,300. This is the direct effect of a price move, before fees or taxes.

In numbers: The outcome for the proposed protection fund is less straightforward. Its options strategy seeks to limit losses, but it also caps gains. Without the final terms and the current limits for the relevant period, it is not possible to calculate reliably what €1,000 invested in this fund would be worth after a particular bitcoin price move.

The filing does not yet provide a final management fee. The final terms may also change before the fund becomes available. Costs matter because they reduce an investment fund’s return.

The existing Bitcoin ETF shows that losses still matter

BlackRock already has a large spot bitcoin product in IBIT. On the official iShares product page, IBIT’s net total return for 2026 was listed at minus 4.48 percent through 29 September 2026. A hypothetical €1,000 investment following exactly that return would have been worth about €955.20, before any taxes or personal trading costs.

This calculation illustrates a past return only. It does not predict what IBIT or the new fund will do next. The iShares page lists an annual sponsor fee of 0.25 percent for IBIT. Those costs reduce returns independently of bitcoin’s price movement.

The US Securities and Exchange Commission warns that bitcoin products are speculative and that investors should understand their risks, costs and fund documents. A product designed to provide protection remains an investment product exposed to market risk.

The filing does not mean the fund is ready to trade

The documents submitted to the US Securities and Exchange Commission describe a proposed fund. The filing says the registration is not yet effective and that the information may change. The SEC has not approved the product simply by receiving the filing.

The final fee, final terms and date when the fund becomes available for trading are therefore important open questions. The ticker PBIT appears in the documents, but that alone does not prove that trading has begun.

European investors face another practical question. A US listed fund is not automatically available through every European broker. Tax treatment also depends on the country where an investor is tax resident and on how the product is held. The Netherlands and Belgium have different tax rules, so investors should check the rules for their own situation with the relevant tax authority or a qualified adviser.

Questions to ask before assessing the product

• Has the fund been formally registered and made available for trading?
• What are the annual fees and any transaction costs?
• What is the maximum potential gain during the chosen period?
• How does the protection change if you invest after a period has started?
• Do you understand the risks and mechanics of the options well enough?
