Corporate Bitcoin Holdings Update: Strategy Halts Purchases, Net Buying by Listed Companies Plunges 83%
According to SoSoValue data, as of June 29, 2026, global publicly traded companies (excluding miners) purchased only $14.65 million worth of Bitcoin last week, an 83% decline from the prior week. Strategy (formerly MicroStrategy) did not buy any Bitcoin for the week. The company announced two separate $1 billion securities repurchase programs targeting Class A common stock and digital credit preferred shares (STRC) with an annual dividend rate of 8%–10%. To fund these repurchases, the board approved a plan to sell up to $1.25 billion of Bitcoin, aiming to replenish USD reserves, pay preferred dividends, or directly support buybacks. Co-founder Michael Saylor stated that Bitcoin remains the primary treasury asset but active capital management is needed to strengthen credit quality. Strategy currently holds approximately 847,000 BTC.
Two other companies purchased Bitcoin last week: Hong Kong-based CIMG received 207.7 BTC (average price $65,000) as part of a stock and warrant issuance, raising total holdings to 937.7 BTC; Brazil's OrangeBTC bought 74 BTC for $4.9 million (average $66,233), bringing its total to 3,896 BTC. Japan's Metaplanet did not buy for the 10th consecutive week. Aggregate corporate holdings (ex-miners) stand at 1,142,484 BTC, worth ~$68.52 billion, representing 5.7% of circulating supply.

ETH Treasury Moves: Bitmine Holdings Hit 5.7M, Sharplink Continues Accumulation
Bitmine Immersion Technologies spent ~$43 million to purchase 27,084 ETH last week, pushing its total holdings to 5.7 million ETH, or ~4.7% of circulating supply. The company now controls ~$9.8 billion in crypto assets and cash, nearing its 5% target but slowing purchases. Chairman Tom Lee attributed recent price weakness to quarter-end window dressing.

SOL-Related Developments: Upexi Raises Funds to Buy SOL, Solmate Shareholder Sues Board
Nasdaq-listed Solana treasury company Upexi signed a securities purchase agreement to sell ~12.24 million common shares at $1.60 each, raising $19.5 million to repay debt and continue accumulating SOL. Separately, RBCH – the largest external shareholder of Solmate Infrastructure (SLMT) – filed a lawsuit in New York Supreme Court against the company's officers and directors, alleging breach of fiduciary duty, misleading statements, and self-dealing. RBCH is linked to RockawayX founder Viktor Fischer and holds ~22.74% of Solmate's parent Brera Holdings. The suit claims the board sold shares while other investors were locked up, signed advisory agreements favoring insiders, and that directors Ron Sade and Keren Maimon personally bought ~2.298 million Class B shares at $4.97 per share, diluting shareholders by ~20%. Fischer says Solmate trades at a ~50% discount to NAV, with shares down 78% year-to-date – among the worst-performing SOL treasury companies.
