This ETF tracks the spot price of Bitcoin one-to-one and uses the Bitcoin Reference Rate (New York variant) as its benchmark index. It holds physical Bitcoin directly and does not use Bitcoin derivative contracts or futures.
It suits investors who want direct exposure to Bitcoin price movements and prefer to invest in a regulated format through a brokerage account.
Launched in 2024 by 21Shares US (co-branded with ARK Invest), it is a passively managed (index-tracking) ETF.

By holding physical Bitcoin directly, the fund tracks the spot price of Bitcoin as is. Rather than derivative contracts or shares of Bitcoin-related companies, it entrusts Bitcoin itself to Coinbase Custody, and all of the held assets are managed in cold storage.
- Dual-brand management by ARK Invest (Cathie Wood) and 21Shares
- Full custody of assets in Coinbase Custody cold storage
Size and Costs
Assets under management (AUM) stand at $2.5B, and the expense ratio is 0.21% per year.
The asset structure is the same as that of peer spot Bitcoin ETFs such as IBIT, FBTC and GBTC shown in the table, but they differ in fee levels and in the fund manager's brand.
Performance and Trends
1-Year Price Performance
Dividend & Yield
52-Week Price RangeSince the approval of spot Bitcoin ETFs, rising institutional inflows have driven rapid growth in assets under management. The fund moves in line with the price of Bitcoin, and it tends to show large short-term volatility depending on the overall strength or weakness of the digital asset market.
After the approval of US spot Bitcoin ETFs, major asset managers rushed to launch products, and institutional money flowed into the category as a whole. ARK Invest's client base of innovative technology investors and 21Shares' global base of digital asset investors are acting as drivers of inflows.
Strengths and Weaknesses
Its strengths are direct exposure to spot Bitcoin and a trusted custody structure, while the high volatility inherent in Bitcoin and regulatory uncertainty are the main risk factors.

⚠️ Points of Caution
Alternative ETFs and Related Products
IBIT (BlackRock), FBTC (Fidelity) and GBTC, shown in the table, are all ETFs with the same structure of directly holding spot Bitcoin, and they differ in fee levels and assets under management. IBIT and FBTC are characterized by large asset manager brands and relatively low fees. BITO, a Bitcoin futures-based product, uses a derivative contract structure rather than holding spot Bitcoin, so roll costs and tracking error can arise. Compared with ETHA, a spot Ethereum ETF, it offers exposure to a different underlying asset within digital assets.

Investor Checkpoints
These are the points to review before investing in ARKB, covering the characteristics of Bitcoin as an asset and the ETF structure. Spot Bitcoin ETFs have different risk characteristics from traditional assets, so checking in advance is important.
| Checkpoint | What to Check | Current Status |
|---|---|---|
| 💵 Expense Ratio | Check the cumulative cost impact of long-term holding and the level relative to competing ETFs | Needs checking |
| 💧 Liquidity and Trading Value | Check daily trading value and bid-ask spread levels | Mid-to-upper range |
| 🔐 Custody Structure | Coinbase Custody cold storage method | Maintained |
| ⚡ Price Volatility | Whether you can tolerate Bitcoin's short-term volatility | Needs checking |
Bitcoin is more volatile than traditional assets, so short-term losses can be large. Risks unique to digital assets, such as changes in the regulatory environment and exchange hacks, also exist. The ETF structure mitigates custody risk, but investors still bear the price risk of the underlying asset, Bitcoin.
As a spot Bitcoin ETF co-branded by ARK Invest and 21Shares, it is a suitable choice for investors who want Bitcoin price exposure in a regulated format. If fee levels or AUM are a higher priority, we recommend also comparing IBIT and FBTC.
