Grayscale Solana Staking ETF 8-K

What Happened

• Grayscale Solana Staking ETF (GSOL) filed an 8‑K on May 13, 2026, disclosing amendments to its Authorized Participant arrangements. Grayscale Investments Sponsors, LLC (the Sponsor) and the Transfer Agent amended the Participant Agreement with Jane Street Capital, LLC to permit that Authorized Participant to conduct creations and redemptions in‑kind.
• The Sponsor stated it may engage additional Authorized Participants in the future, and those Authorized Participants could be authorized to perform creations and redemptions in‑kind, in cash, or both. The Form of Participant Agreement is filed as Exhibit 10.1 and related amendment documents are filed as Exhibits 10.2 and 10.3.

Key Details

• Filing date: May 13, 2026 (Current Report on Form 8‑K).
• Authorized Participant named: Jane Street Capital, LLC — now able to do in‑kind creations and redemptions.
• Sponsor: Grayscale Investments Sponsors, LLC; report signed by Edward McGee, CFO.
• Documents filed as exhibits: Form of Participant Agreement (Ex. 10.1) and Amendments No. 3 and No. 4 (Exs. 10.2, 10.3).

Why It Matters

• The amendments formalize an Authorized Participant’s ability to create and redeem GSOL shares in‑kind — the standard ETF mechanism that lets authorized firms exchange underlying assets for ETF shares and vice versa. That mechanism is central to how ETFs manage share supply and align market price with NAV.
• Allowing additional Authorized Participants (and permitting cash or in‑kind processes) gives the Sponsor operational flexibility that can affect how shares are created/redeemed and how the ETF interacts with market makers and arbitrage activity.
