What Is the BlackRock Bitcoin ETF (IBIT) and How Does It Work?

IBIT stands for the iShares Bitcoin Trust ETF — a spot Bitcoin ETF issued by BlackRock and traded on the NASDAQ stock exchange under the ticker symbol IBIT.

A spot Bitcoin ETF is straightforward: the fund buys and holds real Bitcoin on behalf of investors.

When you purchase an IBIT share, you're gaining price exposure to Bitcoin without ever needing a crypto wallet, a private key, or an account on a crypto exchange.

The ETF launched on January 11, 2024, following approval by the U.S. Securities and Exchange Commission (SEC).

BlackRock charges a 0.25% annual expense ratio — competitive with comparable funds in the market.

The underlying Bitcoin is held in custody by Coinbase Custody Trust Company, LLC, a regulated qualified custodian, with BlackRock having also added Anchorage Digital Bank as an additional custodian as part of its risk management framework.

For investors who want regulated, exchange-based Bitcoin exposure without the technical complexity of direct ownership, IBIT is the most liquid and widely adopted option available.

How BlackRock Became Bitcoin's Biggest Institutional Backer

In 2017, BlackRock CEO Larry Fink publicly dismissed Bitcoin as "an index of money laundering."

By 2023, his firm had filed for a spot Bitcoin ETF with the SEC — a move that marked one of the most consequential opinion reversals in financial history.

What changed? Fink has cited surging client demand, Bitcoin's growing institutional credibility, and its potential role as a hedge against currency debasement and sovereign debt risk.

By late 2025, Fink was describing Bitcoin as an "asset of fear" — something investors reach for during periods of geopolitical and economic uncertainty, much like gold.

IBIT became BlackRock's top revenue-generating product across its entire lineup of over 1,400 ETFs, generating an estimated $245 million in annual fees at its October peak AUM.

Sovereign wealth funds from Abu Dhabi, foundation endowments, and pension managers all began adding IBIT to their portfolios.

The story of BlackRock and Bitcoin is no longer about a firm dipping a toe into crypto — it's about the world's largest asset manager placing a structural, long-term bet on Bitcoin as a legitimate asset class.

How Much Bitcoin Does BlackRock Own?

BlackRock's IBIT has set consecutive all-time highs in Bitcoin holdings since its launch.

As of April 2026, IBIT holds over 806,700 BTC — worth approximately $63.7 billion at prevailing market prices, according to ETF flow data.

That figure represents roughly 49% of all assets held across U.S. spot Bitcoin ETFs, placing IBIT well ahead of every other fund in the category.

IBIT's growth trajectory has been steep: the fund held approximately 303,935 BTC in Q2 2024 and has grown its holdings by approximately 149% since SEC approval.

It took IBIT just 341 trading days to surpass $70 billion in assets under management — a record pace for any ETF in history, across any asset class.

Holdings are held in institutional cold storage through Coinbase Custody Trust Company, with daily transparency published via BlackRock's official iShares holdings data files.

For context, IBIT has periodically traded places with Strategy (formerly MicroStrategy) as the largest publicly disclosed corporate BTC holder.

How to Buy the BlackRock Bitcoin ETF (IBIT) — Step by Step

Buying IBIT is as straightforward as buying any stock.

You need a brokerage account that provides access to NASDAQ-listed securities — most major U.S. platforms support this.

Once your account is funded, simply search the ticker IBIT and place a buy order for however many shares you want.

There's no minimum investment beyond the share price, no crypto wallet required, and no need to manage private keys or navigate a crypto exchange.

IBIT shares are also eligible to be held inside tax-advantaged accounts such as IRAs, which makes them attractive for long-term investors building retirement exposure to Bitcoin.

If you prefer to own Bitcoin directly rather than through an ETF wrapper, you can buy BTC spot on MEXC — where Bitcoin trades 24/7 with deep liquidity and no complex onboarding.

The key difference: IBIT gives you regulated, brokerage-based price exposure; direct Bitcoin ownership gives you the asset itself, with full control over custody.
