Net cash used in investing activities. The changes in net cash used in investing activities primarily relate to purchases of digital assets, advance deposits on a new corporate aircraft, and expenditures on property and equipment. Net cash used in investing activities increased $15.4 billion for the nine months ended September 30, 2025, as compared to the same period in the prior year, primarily due to a $15.4 billion increase in purchases of bitcoins and a $27.0 million deposit on a new corporate aircraft.

Long-term Debt
The terms of each of our long-term debt instruments and the interest payments we have made and are obligated to make on our long-term debt instruments are discussed more fully in Note 5, Long-term Debt, to the Consolidated Financial Statements included in this Quarterly Report as well as Note 8, Long-term Debt, to the Consolidated Financial Statements of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.
We or our affiliates may, at any time and from time to time, seek to retire or purchase our outstanding debt through cash purchases and/or exchanges for equity or debt, in open-market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will be upon such terms and at such prices as we may determine, and will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. We may also seek to prepay our outstanding indebtedness. The amounts involved in any such repurchase or prepayment may be material. We could seek to fund any such debt repurchases or prepayments using proceeds from equity offerings that we may choose to undertake from time-to-time.
Critical Accounting Estimates
Our discussion and analysis of our financial condition and results of operations are based on our Consolidated Financial Statements, which have been prepared in accordance with GAAP. The preparation of our Consolidated Financial Statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, and equity, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results and outcomes could differ from these estimates and assumptions.
Critical accounting estimates involve a significant level of estimation uncertainty and are estimates that have had or are reasonably likely to have a material impact on our financial condition or results of operations. We consider certain estimates and judgments related to revenue recognition to be critical accounting estimates for us, as discussed under “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Estimates” included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024. There have been no significant changes in such estimates and judgments since December 31, 2024.
