SOL: Company Treasury Average Cost by Company
Included with Plus.
The average cost per SOL each company reports: its cost basis divided by the coins it holds.
Why use it. Compares each company's cost with the price: where the price sits against a company's average cost tells whether its treasury is in profit. How to read it. Each line steps when the company files a new figure. The total line is the cost-weighted average of all companies with a cost basis.
Calculation. Cost basis divided by the coins held. Before 2025 most filings carried SOL at cost less impairment, which is not a cost basis; those figures are used only where the filing states the aggregate purchase price. A company's cost basis is the cost its filing reports for the coins. Where a figure states coins without a usable cost (often a quarter-end report, or a dated statement between purchase announcements), it comes from the company's filed costs either side: the next filed cost when the coins are the same; else the previous cost per coin for the same or fewer coins; else the previous cost plus the added coins at the average cost of the coins added up to the next filed cost or, without one, at our own price on that date. A filed cost per coin outside the prices SOL had traded at by then (a figure tagged to the wrong item, or amounts rounded to more than the coins are worth) is not used, and the filing's other cost total for the same coins is used instead where it gives one. Source: the companies' own filings with the US SEC (EDGAR): their 10-K and 10-Q reports and the 8-K announcements in which they state their holdings, or a foreign company's 20-F, 40-F and 6-K, read by CryptoKeyhole every hour since January 2025, when these treasuries began. The companies include Forward Industries, Upexi, Solana Company, SkyAI (Sharps Technology) and DeFi Development; each company's figures are in the breakdown by company. SOL a company has staked count where its filing counts them in SOL; liquid-staking tokens count only where the filing's own figure includes them. Values use CryptoKeyhole's own hourly SOL/USD index from public exchange candles. Each company's figure is the number of SOL it reports holding for its own account in its SEC filings: its quarterly and annual reports (10-Q and 10-K, or a foreign company's 20-F or 40-F, from their XBRL data or, where the data lack it, the report's own sentence), and, for companies that announce their holdings by 8-K or, for foreign companies, 6-K (press releases and monthly updates), those announcements when they state the number. A figure counts from the date it refers to (a report's period end, or the date an announcement gives) until the company's next figure; the filing date is kept separately and is later, often by weeks. A quarterly figure is checked against the fair value the same filing reports, valued at our own price for that day, and is left out where they disagree. Where a company counts coins it has lent or posted as collateral in its holdings, so does its figure here; coins held for customers are not counted. Limitations: filings lag the holdings they report, so recent purchases appear only once filed, and holdings between figures are not known (8-K announcements fill some of the gaps, only when they state the number). Only companies that file their reports with the US SEC are covered (10-K and 10-Q, or 20-F, 40-F and 6-K for foreign companies): companies listed elsewhere that do not file with the SEC, private companies, funds and ETFs are not included. A company enters the totals at its first filed figure, which can be years after it first bought SOL when its earlier reports gave only dollar amounts.
