REX‑Osprey Debuts First U.S. Ethereum Staking ETF on Cboe

The 1940 Act fund passes all validator rewards to investors with monthly distributions.

Overview

  • REX‑Osprey launched the ETH + Staking ETF (ticker ESK) on Sept. 25, marking the first U.S. ETF to pair spot Ethereum exposure with on‑chain staking payouts.
  • ESK is registered under the Investment Company Act of 1940, providing a familiar U.S. regulatory framework for staking-enabled crypto exposure.
  • The fund holds a mix of directly staked ETH and other exchange‑traded products that themselves stake Ethereum.
  • REX Shares and Osprey Funds state that 100% of staking rewards flow through to shareholders, with no portion retained by the issuer.
  • The launch comes as spot ETH ETFs see softer September inflows and ETH prices retreat, while REX‑Osprey’s earlier Solana + Staking ETF has surpassed $300 million in assets and converted to a RIC for tax efficiency.
