Grayscale Ethereum Classic Trust (ETC) provides passive exposure to Ethereum Classic by holding ETC directly in institutional cold storage, targeting share value based on an index price of ETC less fees and liabilities. The Trust held about 7% of all ETC in circulation as of December 31, 2025, with each share representing roughly 0.7850 ETC. As of March 6, 2026, there were 13,993,800 shares outstanding, and non‑affiliate holdings were valued at $115,325,290 on June 30, 2025. Because there is currently no redemption program and creations can be halted, the shares have not tracked net asset value reliably: from May 2018 to December 2025, they traded at premiums up to 458% and discounts up to 77%, with an average 45% discount and a 28% discount at year‑end 2025. The Trust highlights extensive risk factors tied to ETC price volatility, digital asset market structure, evolving regulation, and reliance on third‑party service providers.
Grayscale Ethereum Classic Trust (ETCG) is informing investors how to treat its presence on X (formerly Twitter), especially the use of ticker symbols with a “$” cashtag. When Grayscale-related accounts post cashtags, X automatically links them to pages that aggregate market data, news, and commentary from various third parties.
The trust explains that Grayscale does not control, endorse, or take responsibility for any information on those X-generated pages or other third-party sites reached through them. That content is not authorized or verified by Grayscale and may conflict with its official disclosures. Investors are directed to rely on Grayscale’s Securities and Exchange Commission filings for authoritative and up-to-date information about the trust and its products.
Grayscale Ethereum Classic Trust (ETCG) reported Q3 2025 results reflecting the movement of Ethereum Classic (ETC). Net assets were $203.2 million, up 9% in the quarter as ETC’s principal market price rose to $18.38. The Trust held 11,054,961.678 ETC and had 13,993,800 Shares outstanding. Principal Market NAV per Share was $14.52.
Operations were driven by price action: Q3 net increase in net assets from operations was $16.6 million, including $18.1 million of realized/unrealized gains, offset by a $1.44 million Sponsor’s Fee. For the nine months, net assets decreased by $79.9 million as ETC fell from $25.13 at year-end to $18.38. The annual Sponsor’s Fee is 2.5% of assets, paid in ETC, which also reduces ETC per Share (approximately 0.7900 ETC per Share at September 30, 2025, from 0.8049 at December 31, 2024). No Share creations or redemptions occurred, and the Trust is not operating a redemption program. A post-quarter management reorganization centralized sponsorship under Grayscale Investments; the Sponsor does not expect a material impact on Trust operations.

Effective September 21, 2025, Crypto.com was added to the CoinDesk Ether Classic Price Index after meeting minimum liquidity requirements, and no existing platforms were removed in this quarterly review.
