BlackRock, the world's largest asset manager, dramatically expanded its digital asset footprint in 2025, with its on-chain cryptocurrency portfolio growing from $54.83 billion to $77.35 billion, representing a $22.52 billion increase driven primarily through its spot exchange-traded funds. The accumulation was led by the iShares Bitcoin Trust (IBIT), which held 770,791.5 BTC valued at $67.4 billion as of December 31, 2025. Bitcoin holdings expanded from approximately 552,550 BTC to 770,380 BTC over the year, an increase of 217,830 BTC. IBIT alone attracted $24.7 billion in net inflows during 2025, far outpacing competitors and accounting for the lion's share of the $21.4 billion that flowed into all U.S. spot Bitcoin ETFs. Ethereum delivered even stronger relative growth. BlackRock's iShares Ethereum Trust (ETHA) saw holdings surge from around 1.07 million ETH to 3.48 million ETH, with the value climbing from $3.59 billion to over $10 billion—a 184% increase. ETHA accumulated $12.6 billion in cumulative net inflows since its launch, representing the bulk of the $9.6 billion that flowed into Ethereum ETFs in 2025.$BTC $SOL $BNB #MemeCoinETFs #FedRateCut25bps #NasdaqTokenizedTradingProposal #BinanceAlphaAlert #WriteToEarnUpgrade
