Bitmine Adds $68M of Ether in One Week, Nears 5% Supply Target

What the SEC Filing Shows

Bitmine Immersion Technologies filed a Form 8-K with the U.S. Securities and Exchange Commission on September 14, 2026, disclosing that it bought 27,180 ether during the previous seven days. The company recorded a price of $2,513 per token based on Coinbase data from September 13, 2026, at 5:30 PM Eastern time, giving the one-week purchase a total cost of approximately $68.3 million.

The 8-K is a disclosure form that public companies in the United States must submit to the SEC when something materially important happens. Bitmine used the filing to update investors on its Ethereum treasury strategy, much the same way some companies disclose large asset purchases or acquisitions. The document gives the public a precise count of tokens acquired and the exact price used to calculate the dollar total.

CoinDesk, which first reported the purchase, cited a price of $2,510.75 per ether — roughly $2.25 lower than the figure in the SEC filing. The small gap exists because the two sources recorded the price at slightly different moments. Both numbers round cleanly to $68 million, making the headline figure accurate. The SEC filing is the primary source for the figures in this article.

The Alchemy of 5%: How Close Is Bitmine?

The filing states that Bitmine now holds 5,956,378 ether. Ethereum has roughly 122 million tokens in circulation, a figure the company itself cites in the SEC disclosure. Dividing those numbers gives a 4.9% share, leaving the firm about 144,000 ETH short of the 5% line — a gap the company's own math puts at roughly 2% of the way remaining after fifteen months of buying.

Bitmine calls its strategy the "Alchemy of 5%." The goal is to own 5% of all circulating ether, making the company one of the dominant Ethereum treasury holders globally — comparable in concept to how some firms have built large bitcoin positions tracked on the corporate treasury tracker. The company set this target when the strategy launched on June 30, 2025, and has disclosed progress in each weekly SEC filing since.

Reaching 4.9% in fifteen months reflects a steady accumulation pace rather than a one-time bet. The remaining shortfall of roughly 144,000 ETH exists partly because the circulating supply of ether shifts gradually over time, so the absolute number of tokens needed to hit exactly 5% moves slightly each week. The company has not publicly revised or abandoned the target in any SEC disclosure reviewed for this article.

Tom Lee's Case for Ethereum

Chairman Tom Lee, who co-founded Fundstrat Global Advisors, stated in the filing that the ETH-to-bitcoin ratio had reached its highest level since January 30, 2026. That claim appears in both the SEC 8-K and the company's press release on PR Newswire and is attributed to Lee directly. No independent price-data source was reviewed for this article, so readers should treat the ratio observation as Lee's market assessment rather than an independently confirmed data point.

Lee listed several developments he views as tailwinds for Ethereum. The items below are his forward-looking opinions as stated in the SEC filing and press release — not independently verified market trends. They are listed here because collapsing them into a single sentence would lose the specificity the filing itself provides.

Lee also cited a Fundstrat-calculated figure showing ether outperformed the S&P 500 by 5,866 basis points in the third quarter of 2026. That figure comes from Bitmine's own research affiliate rather than a neutral benchmark provider, so it should be read as a company-supplied performance claim. Secondary reporting has also cited a $6,000 ether price target from Lee, conditioned on bitcoin reaching $150,000 and the ETH-to-bitcoin ratio hitting 0.04; that is a speculative forecast and was not independently verified for this article.

Sixty-Three Weeks of Buying, No Exceptions

The SEC 8-K states that Bitmine "has bought ETH each and every week since the inception of the ETH Treasury Strategy on June 30, 2025." From that start date to the purchase disclosed on September 14, 2026, the company went roughly fifteen months — approximately sixty-three consecutive weeks — without skipping a single purchase. That kind of unbroken cadence is rare among publicly listed companies that hold digital assets on their balance sheets.

The consistency shows the strategy is not opportunistic in the traditional sense — Bitmine does not appear to wait for lower prices before placing its weekly order. The approach resembles a fixed-schedule plan more than a market-timing strategy. Readers curious about how scheduled buying compares to lump-sum purchases can explore the concept using the DCA backtest tool, though that tool is built around bitcoin rather than ether.

The table below summarizes key figures from Bitmine's most recent SEC filing, letting readers compare the single-week purchase to the company's total treasury position at a glance. Every figure comes directly from the Form 8-K filed with the U.S. Securities and Exchange Commission on September 14, 2026, the same disclosure that prompted CoinDesk's initial report.

Each $68 Million Week Brings Bitmine Closer to Its Goal

Bitmine's $68 million purchase is a single chapter in a longer effort to hold more ether than almost any other institution on earth. Each week's Form 8-K filing adds another data point to that arc. The current crypto markets have absorbed these purchases without visible disruption, though the SEC filing itself does not claim any causal link between Bitmine's buying activity and the ETH-to-bitcoin ratio that Lee cited as a positive signal.

Regulatory clarity could shape how quickly institutional buying expands across the broader industry. The Clarity Act, which Lee listed in the filing as a tailwind, is a U.S. legislative effort examined in more depth in bitcoin regulation coverage. Regardless of that bill's progress in Congress, Bitmine's stated plan is to continue buying every week on a fixed schedule rather than pausing for specific price conditions to appear.

The math is direct: Bitmine needs roughly 144,000 more ether to reach 5% of circulating supply. At 27,180 ETH per week, that gap could close in about five weeks if the buying rate holds steady and the supply figure stays roughly constant. The company has not announced any pause in its strategy, and its SEC disclosures have arrived without interruption for fifteen months. The filing record is public and updated each week.
