The SEC's database says CleanSpark holds 1.7 million bitcoin. Its own filing says 1,719.

Ask the Securities and Exchange Commission's data service how much bitcoin CleanSpark, Inc. reported at the end of June 2026 and it will tell you 1,719,000.

There are 20,098,084 bitcoin in existence. The number the SEC's own API returns for one Nasdaq-listed miner is 8.55 percent of all of them, which would make CleanSpark the second largest holder on earth by a wide margin, ahead of every exchange traded fund and every government.

It is not true. CleanSpark's filing does not say that. The number is wrong by exactly one thousand, and the reason is a single attribute in the markup.

What the filing actually says

The document is CleanSpark's quarterly report on Form 10-Q for the period ended 30 June 2026, filed on 6 August 2026 under accession number 0001193125-26-338382.

In the body of that filing, the company writes that at 30 June 2026 it held approximately 12,205 bitcoin, and separately had a receivable for 1,719 bitcoin posted as collateral to derivative trading counterparties. It gives the fair value of that collateral receivable as $100,607 in a table stated in thousands, so roughly $100.6 million.

So 1,719 is a real number in a real filing. It is not CleanSpark's holdings. It is the bitcoin the company has posted elsewhere as collateral and expects back.

Where the thousand comes from

Modern SEC filings carry two layers. There is the document a person reads, and there is inline XBRL, a set of tags wrapped around the numbers so machines can read them without a human retyping anything.

We pulled the filing and read the tags. The number 1,719 is tagged with the crypto asset units concept, with a unit of Bitcoin, and it carries two attributes: a scale of 3 and decimals of minus 3.

A scale of 3 is an instruction to any machine reading the document: multiply the displayed value by ten to the power of three. It exists because financial tables are so often printed in thousands or millions. A table showing revenue of 4,512 with "in thousands" at the top tags that number with a scale of 3 so the machine records $4,512,000 rather than $4,512.

Applied to 1,719 bitcoin, it produces 1,719,000 bitcoin.

The comparative figure in the same filing, 2,583 bitcoin as at 30 September 2025, carries decimals of 0 and no scale attribute at all. It comes through correctly.

The most likely explanation is the simplest one. The bitcoin count sits in a sentence next to a dollar figure that genuinely is in thousands. Whoever tagged it applied the table's convention to a number already stated in whole coins. That is our reading of the evidence, not something the company has told us.

It is still live

This is not a historical curiosity that was fixed the following week. We queried the SEC's company concept API on 16 October 2026, more than two months after the filing, and it still returns the wrong figure. The series reads:

• 30 September 2024: 1,229, from a 10-K filed 25 November 2025
• 30 September 2025: 2,583, from the same 10-K
• 31 December 2025: 1,648, from a 10-Q filed 5 February 2026
• 31 March 2026: 1,641, from a 10-Q filed 11 May 2026
• 30 June 2026: 1,719,000, from the 10-Q filed 6 August 2026

Five consecutive quarters between roughly 1,200 and 2,600, and then one a thousand times larger.

Why this matters more than a typo

The SEC's structured data is not a backwater. It is the plumbing. Screeners, terminals, research tools, academic datasets and a growing number of automated agents read company figures from exactly this endpoint, because it is free, official and machine readable. Nobody in that chain opens the PDF.

Any one of them that asked for CleanSpark's reported bitcoin units in the last two months got 1,719,000.

There is a second problem underneath the first, and it is quieter. Even the correct value, 1,719, is not what most people would assume. CleanSpark is using the crypto asset units tag for a collateral receivable, not for the coins it holds. We checked four other filers using the same tag, Strategy, Block, American Bitcoin and GameStop, and in each case the tagged number is the company's actual holdings. CleanSpark is the odd one out.

So a tool collecting this tag across every filer does two wrong things with CleanSpark at once: it takes a receivable for a holding, and then multiplies it by a thousand.

How we found it

By accident, and because we assumed our own numbers were broken before we assumed the SEC's were.

BTC Newz publishes a statistics page that rebuilds itself every week from the SEC's data, among other primary sources. When it ran, CleanSpark came back holding more bitcoin than every ETF combined. A guard we had written for exactly this kind of thing, which rejects any filing more than twenty times the company's own previous one, refused the number and flagged it.

The page names the excluded filing rather than quietly averaging it away. We then went to the filing to find out which of us was wrong. It turned out to be neither the company's accounts nor our arithmetic, but the layer in between.

What should happen

Nothing here suggests CleanSpark has misstated its accounts. The document a human reads is internally consistent and the figures in it are sensible. This is a markup error, which is the least interesting kind of error right up until a machine reads it and acts on it.

The fix is a corrected filing, which would push a clean value into the API. Until that happens the number stands in the public record, and anyone pulling CleanSpark's bitcoin figure from the SEC rather than from the filing is getting a number wrong by three orders of magnitude.

CleanSpark has not published a correction to this filing as of 16 October 2026. We have not received a statement from the company.
