Item 8.01. Other Events.
Prior to October 1, 2025, Grayscale Stellar Lumens Trust (XLM) (the “Trust”) valued the XLM held by the Trust for operational purposes by reference to the CoinDesk Stellar Lumens Index (XLMX). As of October 1, 2025, the Index will be the CoinDesk XLM CCIXber Reference Rate. As of October 1, 2025, the NAV and NAV per Share of the Trust will be calculated using the Index Price based on the CoinDesk XLM CCIXber Reference Rate. Prior to October 1, 2025, references to the “Index” in the Trust's filings with the SEC refer to the CoinDesk Stellar Lumens Index (XLMX). From and after October 1, 2025, references to the “Index” in the Trust's filings with the SEC will be to the CoinDesk XLM CCIXber Reference Rate.
Capitalized terms used but not defined herein have the meanings ascribed to them in the Trust’s Annual Report on Form 10-K for the fiscal year ended September 30, 2024.
Constituent Trading Platform Selection
Under the CCIXber methodology, The Digital Asset Trading Platforms to be included in the Index are selected by the Index Provider utilizing a methodology that is guided by the International Organization of Securities Commissions (“IOSCO”) principles for financial benchmarks. For a trading platform to become a Constituent Trading Platform, it must satisfy the criteria listed below (the “Inclusion Criteria”):
All trading platforms that meet these Inclusion Criteria will be assigned to a “Trading Platform Category” as defined by the additional criteria below, and at least one Category 1 Trading Platform must be included in each Index Price.
A Digital Asset Trading Platform is removed from the Constituent Trading Platforms when it no longer satisfies the Inclusion Criteria. The Index Provider does not currently include data from over-the-counter markets or derivatives platforms among the Constituent Trading Platforms. Over-the-counter data is not currently included because of the potential for trades to include a significant premium or discount paid for larger liquidity, which creates an uneven comparison relative to more active markets. There is also a higher potential for over-the-counter transactions to not be arms-length, and thus not be representative of a true market price. XLM derivative markets are also not currently included. While the Index Provider has no plans to include data from over-the-counter markets or derivative platforms at this time, the Index Provider will consider IOSCO principles for financial benchmarks, the management of trading venues of XLM derivatives and the aforementioned Inclusion Criteria when considering whether to include over-the-counter or derivative platform data in the future.
The Index Provider and the Sponsor have entered into the index license agreement, dated as of February 1, 2022 (as amended, the “Index License Agreement”), governing the Sponsor’s use of the Index Price. Pursuant to the terms of the Index License Agreement, the Index Provider may adjust the calculation methodology for the Index Price without notice to, or consent of, the Trust or its shareholders. The Index Provider may decide to change the calculation methodology to maintain the integrity of the Index Price calculation should it identify or become aware of previously unknown variables or issues with the existing methodology that it believes could materially impact its performance and/or reliability. The Index Provider has sole discretion over the determination of the Index Price and may change the methodologies for determining the Index Price from time to time. Shareholders will be notified of any material changes to the calculation methodology or the Index Price in the Trust’s current reports and will be notified of all other changes that the Sponsor considers significant in the Trust’s periodic or current reports. The Sponsor will determine the materiality of any changes to the Index Price on a case-by-case basis, in consultation with external counsel.
The Index Provider may change the trading venues that are used to calculate the Index or otherwise change the way in which the Index is calculated at any time. For example, the Index Provider has scheduled quarterly reviews in which it may add or remove Constituent Trading Platforms that satisfy or fail the Inclusion Criteria. The Index Provider does not have any obligation to consider the interests of the Sponsor, the Trust, the shareholders, or anyone else in connection with such changes. While the Index Provider is not required to publicize or explain the changes or to alert the Sponsor to such changes, it has historically notified the Trust of any material changes to the Constituent Trading Platforms, including any additions or removals of the Constituent Trading Platforms, in addition to issuing press releases in connection with the same. The Sponsor will notify investors of any such material event by filing a current report on Form 8-K. Although the Index methodology is designed to operate without any manual intervention, rare events would justify manual intervention. Intervention of this kind would be in response to non-market-related events, such as the halting of deposits or withdrawals of funds on a Digital Asset Trading Platform, the unannounced closure of operations on a Digital Asset Trading Platform, insolvency or the compromise of user funds. In the event that such an intervention is necessary, the Index Provider would issue a public announcement through its website, API and other established communication channels with its clients.
Determination of the Index Price
The Index, as will be reflected by the CoinDesk XLM CCIXber Reference Rate, for XLM is calculated through the application of an algorithm to the price of XLM on the Constituent Trading Platforms calculated every 5 seconds over a 24-hour period. The Index’s algorithm is expected to reflect a five-pronged methodology to calculate the Index Price from the Constituent Trading Platforms for XLM:
The Index Provider re-evaluates the weighting algorithm on a periodic basis, but maintains discretion to change the way in which an Index Price is calculated based on its periodic review or in extreme circumstances. The exact methodology to calculate the Index Price is not publicly available. Still, the Index is designed to limit exposure to trading or price distortion of any individual Digital Asset Trading Platform that experiences periods of unusual activity or limited liquidity by discounting, in real-time, anomalous price movements at individual Digital Asset Trading Platforms.
The Sponsor believes the Index Provider’s selection process for Constituent Trading Platforms as well as the methodology of the Index Price’s algorithm provides a more accurate picture of XLM price movements than a simple average of Digital Asset Trading Platform spot prices, and that the weighting of XLM prices on the Constituent Trading Platforms limits the inclusion of data that is
influenced by temporary price dislocations that may result from technical problems, limited liquidity or fraudulent activity elsewhere in the XLM spot market.
By referencing multiple trading venues and weighting them based on trade activity, the Sponsor believes that the impact of any potential fraud, manipulation or anomalous trading activity occurring on any single venue is reduced.
If the Index Price becomes unavailable, or if the Sponsor determines in good faith that such Index Price does not reflect an accurate price for XLM, then the Sponsor will, on a best efforts basis, contact the Index Provider to obtain the Index Price directly from the Index Provider. If after such contact such Index Price remains unavailable or the Sponsor continues to believe in good faith that such Index Price does not reflect an accurate price for the XLM , then the Sponsor will employ a cascading set of rules to determine the Index Price, as described below in “—Determination of the Index Price When Index Price is Unavailable.”
The Trust values its XLM for operational purposes by reference to the Index Price. The Index Price is the value of an XLM as represented by the Index, calculated at 4:00 p.m., New York time, on each business day.
Illustrative Example
For the purposes of illustration, outlined below are examples of how the attributes that impact weighting and adjustments in the aforementioned methodology may be utilized to generate the Index Price for a digital asset.
For example, Constituent Trading Platforms used to calculate the Index Price of the digital asset may include trading platforms such as Crypto.com, Kraken, LMAX Digital and Bitstamp by Robinhood.
The Index Price algorithm, as described above, is designed to account for manipulation at the outset by only including data from executed trades on Constituent Trading Platforms that charge trading fees. Then, the below-listed elements may impact the weighting of the Constituent Trading Platforms on the Index Price as follows:
Determination of the Index Price When Index Price is Unavailable
The Sponsor uses the following cascading set of rules to calculate the Index Price. For the avoidance of doubt, the Sponsor will employ the below rules sequentially and in the order as presented below, should one or more specific rule(s) fail:
In the event of a fork, the Index Provider may calculate the Index Price based on a digital asset that the Sponsor does not believe to be the appropriate asset that is held by the Trust. In this event, the Sponsor has full discretion to use a different index provider or calculate the Index Price itself using its best judgment.
The Sponsor may, in its sole discretion, select a different index provider, select a different index price provided by the Index Provider, calculate the Index Price by using the cascading set of rules set forth above, or change the cascading set of rules set forth above at any time. The Sponsor will provide notice of any such changes in the Trust’s periodic or current reports and, if the Sponsor makes such a change other than on an ad hoc or temporary basis, will file a proposed rule change with the SEC.
