As of December 19, 2025, crypto asset manager Bitwise has submitted a Form S-1 registration to the U.S. Securities and Exchange Commission (SEC) for a spot Sui ETF—a fund that would hold actual SUI tokens to track the Layer-1 blockchain’s native asset price. This filing marks Bitwise’s latest expansion into altcoin ETFs, joining competitors like Grayscale, 21Shares, and Canary Capital in the race for regulated SUI exposure. With Coinbase as proposed custodian and potential staking features, the product aims to deliver direct returns (including yields) to traditional investors.
This development highlights growing institutional interest in high-performance blockchains beyond Bitcoin and Ethereum, amid a wave of 2025 crypto ETF approvals.

The S-1 outlines a straightforward spot product:
- Structure: Physically backed by SUI tokens (in-kind creations/redemptions).
- Custodian: Coinbase Custody for secure storage.
- Unique Feature: Plans to include staking rewards—generating extra SUI for holders.
