What Is BLOK? Amplify Blockchain Technology ETF

BLOK is the Amplify Blockchain Technology ETF, an actively managed fund from Amplify ETFs launched in January 2018. Rather than tracking an index, its managers select companies tied to blockchain and digital-asset infrastructure, including crypto miners, exchanges, and trading platforms. It is a thematic way to hold the blockchain industry in a single ticker.

BLOK, listed on NYSE Arca. The full name is the Amplify Blockchain Technology ETF, issued by Amplify ETFs. It was previously known as the Amplify Transformational Data Sharing ETF before adopting its current name.

BLOK is actively managed, so it does not track a published index. Its managers choose holdings based on companies' involvement in blockchain and digital-asset businesses. That gives it flexibility to shift the roster, but also means results depend on the managers' selections rather than a fixed rules-based benchmark.

The fund concentrates in companies tied to blockchain and digital assets. Recent top holdings include Cipher Digital, Figure Technology Solutions, Galaxy Digital, TeraWulf, Hut 8, Robinhood, Advanced Micro Devices, Core Scientific, and Opera. See the top-10 table above for current weights. The lineup skews toward crypto miners, exchanges, and trading platforms.

0.70% per year, or $70 annually on a $10,000 position, deducted from the fund's NAV. That is high relative to broad index ETFs and reflects both the active management and the specialized thematic focus. Cost is one reason a thematic fund like this is usually held in smaller size.

Approximately 0.78% as of July 2026. Dividend income is a minor part of the return story here; many holdings are growth-oriented digital-asset companies that pay little or nothing, so total return is driven far more by price movement than by distributions.

BLOK trades like any stock during US market hours and is available at major brokers such as Robinhood, Fidelity, Schwab, Public, and Webull, with fractional shares supported at many of them. If you want to hold BLOK as a thematic satellite alongside a broad core, you can connect your broker to Walnut and use the AI to see how it fits.

Approximately $1.16 billion as of July 2026. That makes it one of the larger blockchain-themed equity ETFs, though it is small compared with broad-market funds. Assets in thematic crypto-adjacent funds tend to swing with digital-asset market cycles.

BLOK offers concentrated, actively managed exposure to the blockchain industry, which can rise and fall sharply with crypto-market sentiment. It is far more volatile than a broad index fund and carries a higher 0.70% fee. Walnut is not an investment adviser; whether BLOK fits depends on your risk tolerance, time horizon, and how much thematic exposure you already hold.

January 2018. It was one of the earlier blockchain-themed ETFs to launch in the US and originally traded under the name Amplify Transformational Data Sharing ETF before being renamed the Amplify Blockchain Technology ETF.

BLOK holds shares of companies involved in blockchain and digital assets, not cryptocurrency tokens themselves. Its exposure comes through equities such as miners, exchanges, and infrastructure providers, so its returns correlate with crypto markets without the fund custodying coins directly.

It has paid modest distributions, with a yield near 0.78% as of July 2026. Income is incidental to the strategy; the fund is designed for exposure to blockchain-related equities, and most of its return potential comes from share-price appreciation rather than dividends.

BLOK concentrates in a single, cyclical theme whose companies are tightly linked to digital-asset prices. Crypto miners and trading platforms can move dramatically with Bitcoin and broader crypto sentiment, so the fund experiences sharper swings than a diversified fund spread across many sectors.

A spot Bitcoin ETF aims to track the price of Bitcoin itself. BLOK instead holds a basket of companies that build or use blockchain technology, so its returns depend on those businesses' fortunes as well as crypto sentiment. BLOK is more diversified across the industry but does not directly mirror the price of any single cryptocurrency.

Put a few fields side by side: the expense ratio (fees compound over decades), the index or strategy it tracks, the top holdings and how much they overlap with what you already own, the dividend yield, and the AUM, liquidity, and bid-ask spread that affect trading costs. For index funds, tracking error (how closely it follows its index) and tax efficiency matter too. BLOK's figures are above; the full method is in Walnut's guide on how to compare ETFs.
