What Is a Spot ETF?

A Spot ETF is an exchange-traded fund that seeks to track the real-time price of an asset by holding the asset directly in custody. For crypto, Spot Bitcoin and Spot Ethereum ETFs hold actual BTC or ETH with qualified custodians and reflect the underlying market price. This comprehensive beginner guide explains core concepts, how Spot ETFs work, why they matter, risks to consider, and how they compare to futures-based ETFs and index ETFs.

What Makes a Spot ETF “Spot”

Direct Exposure: Holds the underlying asset (e.g., BTC, ETH, gold) in custody.
Transparent Operations: Disclosures on holdings, methodology, and incident handling.
Price Alignment: AP creation/redemption narrows premium/discount vs NAV.

Participants and Roles

Issuer: Designs and manages the fund, sets policies, and reports data.
Authorized Participants (APs): Create/redeem shares; anchor ETF price to spot.
Market Makers: Provide liquidity via continuous quotes.
Custodian: Stores assets securely, with audits and insurance clarity.

Creation/Redemption and Price Alignment When ETF prices deviate from spot, APs create/redeem shares to arbitrage the difference:

Premium: APs deliver underlying or cash to create shares; sell shares; price converges.
Discount: APs buy shares and redeem for underlying or cash; price converges. See How Does a Spot ETF Work? for step-by-step mechanics.

Custody Essentials

Cold Storage Dominance: Minimal hot wallet use for crypto.
Segregation and Multi-Sig: Role separation and multi-party approvals.
Audits and Attestations: Independent verification of holdings and controls.
Insurance Scope: Defined coverage for custody-related risks. Read How Spot Bitcoin ETFs Hold Real BTC.
