The big picture
The Week
Strategy (MSTR) acquired 17,994 BTC ($1.3B) on March 9th, dominating a week in which corporate BTC buying totaled 18,000 BTC across three filers. The purchase occurred as BTC declined 6.4% week-over-week and fear-greed sentiment hit extreme lows, suggesting the company executed against volatility rather than momentum. ETH treasury activity remained modest: Parataxis Ethereum added 2,577 ETH ($5.8M), its first disclosed purchase. No new stackers entered the cohort this week, and no meaningful sells occurred.

Notable Filings
Bullish disclosed a cumulative BTC position of 21,240 BTC (up 2,760 BTC / $193.1M since last disclosure) and an ETH position of 12,520 ETH (up 49,130 ETH / $171.5M since last disclosure) in its 20-F filing. BitMine Immersion Technologies revealed holdings of 4,534,563 ETH, up 60,976 ETH / $121.6M cumulatively. SharpLink Gaming disclosed 868,699 ETH, up 5,275 ETH / $10.5M. These are multi-period balance updates, not single-week acquisitions. Strategy's filing URL points to an internal document rather than an SEC submission.

BTC treasury companies now hold 845,256 BTC across the tracked cohort, versus 772,786 BTC in the largest spot ETF (IBIT). Strategy alone controls 56% of institutional non-ETF BTC holdings by count. ETH positions have grown sharply: BitMine's 4.5M ETH makes it a larger holder than any single BTC company except Strategy, yet receives minimal mainstream scrutiny — a sign the ETH treasury narrative remains fragmented across smaller, less-liquid filers.
