How exactly does spot cryptocurrency ETFs work?

Operating mechanism of spot cryptocurrency ETF

A spot cryptocurrency ETF will actually buy and hold the corresponding cryptocurrency, place it in the custody of an institutional custodian, and then issue shares that can be traded on stock markets such as the New York Stock Exchange High Growth Board, Nasdaq and Chicago Board Options Exchange. Each share represents proportional ownership of the real cryptocurrency stored in the cold wallet, while the continuous arbitrage cycle keeps the share price close to the spot market. It sounds simple, but this simplicity is its core product. Since the launch of the Bitcoin ETF in January 2024, it now covers XRP, SOL,$DOGE,$LINK,$AVAX and $DOT, and there are the same few issuers behind almost every code, while Wall Street giants have also begun issuing their own funds.

What do investors actually buy?

Investors buy and sell ETF shares during regular trading hours through ordinary securities accounts, including in many individual retirement accounts and other retirement accounts. No wallet, no exchange account, no private key. The fund itself handles all these aspects.

The core indicator is net asset value: that is, the value of cryptocurrency held by the fund minus liabilities, divided by the share in circulation. Issuers publish net asset value daily and typically stream indicative intraday values based on real-time spot pricing benchmarks, so the market always knows what a share should be worth.

What makes share prices real?

There is no force forcing buyers and sellers to trade at net asset value. The mechanism to bring market prices back on track is creation and redemption, executed by authorized participants. These authorized participants are large banks and trading companies that directly trade with issuers 'creation units in tens of thousands of shares.

Arbitrage works in both directions: When an ETF trades at a premium, the participant is authorized to deliver cryptocurrency or cash to the issuer, obtain a newly minted share based on the net asset value, and sell it in the market. New supply compresses the premium. When an ETF is traded at a discount, the participant is authorized to buy a cheap share, redeem it from the issuer as the underlying cryptocurrency or cash, and sell the cryptocurrency. Reduced supply pushed prices back to near net asset value. Because authorized participants can benefit from any spread, spreads rarely persist. This is the engine of the entire structure and why spot products track their assets far more cleanly than futures funds, which suffer from rollover costs and premiums.

On July 29, 2025, the U.S. Securities and Exchange Commission approved the physical creation and redemption of Bitcoin and Ethereum spot ETFs, and this mechanism has been significantly upgraded. Previously, the agency imposed a pure cash model, meaning issuers had to sell cryptocurrency and transfer cash with each redemption. The physical model allows authorized participants to directly exchange shares for the cryptocurrency itself, which means fewer market transactions, lower slip points, better tax treatment within the fund, and smaller tracking errors. Newer altcoin funds have this feature built into from the beginning.

Who owns cryptocurrencies?

Hosted services are handled by specialized institutional providers, the most common being Coinbase Custody and a few peers such as BNY and Anchorage Digital. Cryptocurrency is stored in cold wallets with multi-signature controls, insurance and audited operational security measures. Issuers do not hold private keys like retail users do.

Rates for single-asset spot products are mostly between 0.14% and 0.35%, with older trust conversion products sometimes higher. Funds that track evidence-of-equity assets are increasingly pledging some of their positions and passing on the proceeds (after deducting fees) to the fund. VanEck's Avalanche Fund made its first pledged cash distribution in July 2026, covering gains earned since January.

How did the tide of altcoins emerge?

For years, each cryptocurrency ETF has required a separate review by the U.S. Securities and Exchange Commission, which can take as long as 240 days. This changed on September 17, 2025, when the U.S. Securities and Exchange Commission approved common listing standards based on commodity exchange-traded products. Eligible funds can be listed within approximately 75 days once the registration statement takes effect.

The floodgates will open in a few weeks: XRP: Canary Capital's XRP ETF will be listed on Nasdaq on November 13, 2025, setting a record for the largest first-day trading volume of an ETF among any asset class that year. Bitwise followed up on November 20, and Grayscale's GXRP went public on November 24. Dogecoin: REX-Osprey's DOJE took the lead in September 2025, and Grayscale's GDOG and others joined the November wave. Chainlink: Grayscale's GLNK began trading on December 2 on the New York Stock Exchange's High Growth Board. Avalanche: VanEck's VAVX will be first listed on Nasdaq on January 26, 2026, with built-in pledge function. Bitwise's BAVA (on the New York Stock Exchange) and Grayscale's GAVA are now also traded together. Polkadot: TDOT for 21Shares covers DOT. Multi-asset: Index products such as Bitwise's 10 Cryptocurrency Index ETF package BTC, ETH, XRP, SOL, etc. in one code.

Looking at the names of these issuers, one pattern will be found: BlackRock, Grayscale, Bitwise, Canary Capital, 21Shares, VanEck, Fidelity and Franklin Templeton appear repeatedly. The companies building Bitcoin and Ethereum products are simply extending the same custody relationships, authorized participant networks, and market-making pipelines to new assets.

Why are banks starting to appear now?

BlackRock's IBIT sets institutional benchmarks for size and liquidity, with a rate of 0.25%. The latest entrants are competing for price and distribution, not novelty.

Morgan Stanley made this clear. On April 8, 2026, it launched the Morgan Stanley Bitcoin Trust on the New York Stock Exchange's High Growth Board with a rate of 0.14%, which is the lowest rate among U.S. listed spot Bitcoin ETFs and the first such funds issued in their own names by major U.S. banks. Coinbase and BNY are responsible for hosting. The fund absorbed more than $100 million in its first week, reaching $233 million in a month, according to SoValue.

The bank did not stop at ETFs. On July 16, 2026, its E*TRADE platform completed the deployment of spot trading functions for Bitcoin, Ethereum and Solana through infrastructure partner Zero Hash, allowing 8.6 million self-guided households to directly access cryptocurrency at a rate of 50 basis points. Morgan Stanley has also applied for Solana ETF exposure.

Traditional asset management companies are also pouring in. On the same day that E*TRADE was launched, T. Rowe Price launched TKNZ on the New York Stock Exchange's High Growth Board. This is the industry's first actively managed multi-token spot cryptocurrency ETF, holding $BTC,$ETH,$BNB,$XRP,$SOL,$HYPE, etc., with a rate of 0.75%.

The structural core of these products remains the same: physical holding, authorized participant arbitrage, institutional custody and exchange listing. What is constantly changing are rates, pledge functions and distribution channels. MSBT's first $233 million came before Morgan Stanley's approximately 16,000 financial advisers were allowed to recommend the fund to clients. The approval is still pending.
