Today we detected a large options sweep on BMNR, with traders buying 4,384 call contracts at the $30 strike expiring on August 21, 2026. The total premium paid is approximately $1.1 million, indicating a significant capital commitment. Notably, the total volume of 6,853 contracts compared to open interest of 2,502 results in a V/OI ratio of about 2.74, suggesting this is fresh positioning rather than closing trades.
The contracts were bought at the ask price ($2.50), reinforcing the aggressive nature of the order flow. With the stock currently trading around $22.82, this is an out-of-the-money bet with roughly four months until expiration, implying traders are anticipating a meaningful move in BMNR over the medium term.
Volume and Open Interest Data
The volume and open interest data for the BMNR $30 calls expiring August 21, 2026 shows a significant spike in activity on 04/23/26, with volume surging to 7,953 contracts compared to open interest of 2,502. This creates a very high volume-to-open-interest ratio, signaling a wave of new positioning rather than routine trading. In the days leading up to this, volume remained relatively muted while OI stayed stable around ~2,580, suggesting little prior buildup.
Despite the surge in volume, open interest actually declined slightly on the day (-78), which could indicate some closing activity mixed in, but the magnitude of volume strongly points to aggressive new flow. Additionally, contract prices pulled back from 2.77 to 2.32 while implied volatility dipped slightly, potentially offering more attractive entry levels for buyers. Overall, the data reflects a sudden and notable increase in interest in these calls, consistent with speculation or positioning.
What’s Happening with BMNR
Bitmine Immersion Technologies has made a series of headline‑grabbing moves centered on massive Ethereum accumulation, balance‑sheet expansion, and a push up‑listing its stock. In mid‑April and again on April 20–21, 2026, the company announced that its ETH holdings had risen to about 4.976 million tokens, giving it more than 4% of the total ETH supply (~120.7 million coins) and bringing its combined crypto and cash holdings to roughly $12.9 billion, up from about $11.8 billion just days earlier as it added more ETH.
Management frames this as progress toward its self‑described “Alchemy of 5%” plan—an aggressive goal to control 5% of all ETH, and says it has already reached 81–82% of that target within just nine months, positioning Bitmine as one of the largest single ETH holders globally. Alongside the accumulation narrative, Bitmine disclosed that it had received approval to transfer its listing from NYSE American to the New York Stock Exchange, signaling a step up in market profile, and previously secured shareholder approval to increase its authorized share count, giving it flexibility to raise additional capital to fund further Ether purchases or acquisitions—moves that have drawn investor attention both for the upside leverage to ETH and the risk of dilution.
