"The Trust is not an investment company registered under the Investment Company Act of 1940, as amended."

A U.S. federal law that sets the rulebook for pooled investment vehicles such as mutual funds, exchange-traded funds and similar money managers, requiring them to register with regulators, disclose holdings and fees, limit conflicts of interest, and follow governance standards. It matters to investors because these protections and transparency rules act like a referee and scoreboard, helping people compare funds, trust that managers follow fair practices, and spot hidden costs or risks.

FAQ

AI-generated questions and answers. How Rhea-AI works. Not financial advice.

What change is Grayscale Solana Staking ETF (GSOL) proposing in this supplement?

The Sponsor intends to adopt a Third Amended and Restated Trust Agreement that would require the Trust to regularly convert staking consideration into cash and distribute net staking rewards to shareholders, along with other conforming changes to its staking program.

When is the proposed amendment for GSOL expected to become effective?

The amendment is expected to become effective on or around August 7, 2026. On that date, the Third Amended and Restated Trust Agreement would replace the existing agreement and the new distribution framework for staking rewards would begin to apply.

How will GSOL distribute staking rewards under the proposed amendment?

The Trust would be required to reduce Staking Consideration to cash no less often than quarterly and promptly distribute the cash proceeds, net of Trust expenses and a portion paid to the Sponsor, to shareholders as regular distributions of staking rewards.

Can investors predict the size of future staking distributions from GSOL?

No. The supplement states distribution amounts will depend on Staking Consideration actually received by the Trust in each period and cannot be predicted with certainty, so payout levels may vary over time based on staking rewards.

Are there tax considerations for GSOL investors related to the new distribution framework?

Yes. The supplement advises shareholders to discuss any tax consequences of the proposed amendment and resulting distributions with their tax advisors, as the change to regular cash payouts from staking rewards may affect individual tax situations.

Is Grayscale Solana Staking ETF (GSOL) registered as an investment company?

No. The supplement reiterates that the Trust is not an investment company registered under the Investment Company Act of 1940, meaning it operates under a different regulatory framework than traditional registered investment companies.
