Section 01 The Week

BitMine Immersion Technologies (BMNR) acquired 98,852 ETH for $297.3 million on December 22nd, the sole corporate treasury filing this week. The purchase represents a significant ETH accumulation move by the immersion-cooling technology firm, placing it squarely into the ethereum stacking cohort. No new corporate stackers entered BTC or SOL positions this week. The broader BTC market moved 0.95 percent higher over seven days; fear and greed sentiment sits at 47, neutral.

Section 02 Notable Filings

BitMine Immersion Technologies' 98,852 ETH acquisition on December 22nd appears to lack a corresponding SEC filing in the data bundle, leaving the strategic rationale undocumented in traditional regulatory channels. This contrasts with established corporate treasury filers like Strategy (MSTR) and Block.one, whose moves typically generate 8-K disclosures or press releases. The ethereum purchase at $3,007.85 per token warrants monitoring for any subsequent filings that explain the timing and balance-sheet intent.
