In a groundbreaking move to bring cryptocurrency staking to mainstream investors, REX Shares has filed for Ethereum (ETH) and Solana (SOL) staking ETFs, leveraging a creative legal structure under the Investment Company Act of 1940 (40-Act) to bypass the SEC’s sluggish Rule 19b-4 approval process. By structuring the funds as C-corporations with wholly owned Cayman Islands subsidiaries and filing under Rule 485(b) for immediate effect, REX Shares aims to deliver staking yields, potentially 3–7% annually, alongside price exposure to ETH and SOL. This bold strategy, set to list on Nasdaq, allocates 50–80% of assets to staking through offshore subsidiaries, capitalizing on recent SEC guidance from late May 2025 that proof-of-stake (PoS) activities do not constitute securities transactions under the Howey Test.
The innovative approach sidesteps traditional regulatory hurdles that have long delayed crypto-related financial products in the U.S. Historically, the SEC has been skeptical of staking, often hinting it could involve unregistered securities, especially after Ethereum’s transition to PoS and enforcement actions against platforms like Kraken. However, the SEC’s recent clarification, that staking rewards are generated by blockchain protocols, not third-party efforts, has opened a window for REX Shares to act. By using a C-corp structure, the funds can recognize staking income, pay corporate taxes, and distribute after-tax rewards as dividends to shareholders, while the Cayman subsidiaries hold and stake the assets outside U.S. regulatory constraints. This allows mainstream investors to access staking yields without the technical complexities of managing validator nodes or private keys, all within a regulated ETF wrapper traded on public exchanges with institutional custodians like Anchorage Digital.
The market implications are significant. Amid a crypto ETF boom, spot Bitcoin ETFs have attracted billions, and Solana briefly surpassed Ethereum in staking value in April 2025, REX Shares’ ETFs could mark a turning point for PoS assets as a legitimate yield-generating asset class. Industry analysts, including Bloomberg’s James Seyffart, initially hailed the filing as a game-changer, predicting a launch as early as mid-June 2025. The move reflects a broader trend of financial innovation, where issuers use creative legal tools to navigate regulatory constraints, blending finance, law, and technology to accelerate crypto adoption. If successful, this could set a precedent for other asset managers, paving the way for a wave of staking-based ETFs and further integrating blockchain-native features into traditional markets.
However, the path forward is fraught with challenges. On May 31, 2025, the SEC raised concerns, questioning whether these funds meet the legal definition of an “investment company” and flagging their corporate structure as potentially misleading, echoing past regulatory pushback like the PRIV case. This scrutiny has tempered optimism, though REX Shares’ counsel remains confident in resolving the issues. The C-corp structure introduces double taxation, corporate taxes reduce the effective yield compared to direct staking, and ETF management fees further cut into returns. Investors also face tax complexities, as staking rewards may be treated as income, complicating reporting. Additionally, the use of offshore subsidiaries raises concerns about custody, regulatory oversight, and potential future policy changes. The underlying assets’ volatility, staking risks like slashing penalties, and Solana’s lack of spot ETF approval add further uncertainty.
As REX Shares navigates this high-stakes dance between innovation and regulation, the outcome could reshape the crypto ETF landscape. Will the SEC intervene further, or will this become a new pathway for crypto yield products in traditional markets? For now, investors and industry watchers are left watching a pivotal moment unfold, one that could either accelerate the mainstream adoption of staking or highlight the persistent regulatory friction in the evolving crypto-finance space.
