SpaceX's move is quite significant, placing 18k BTC in their financial report.

SpaceX disclosed in its latest S-1 filing that it holds approximately 18,712 Bitcoins, with a market value of about $1.4 billion, a cost basis of $661 million, accounting for roughly 1.8% of total assets, making it one of the few institutional major corporate Bitcoin holders. If measured at fair value, Bitcoin price fluctuations will directly impact financial reports, causing quarterly profit volatility and accounting noise, or making it difficult for investors to assess true operational performance. Bitcoin holdings may shift from strategic reserve assets to a key variable affecting financial report stability.
