Deep Dive
1. Bitcoin Inflows
The strongest single session this week came on Dec 10, when U.S. Bitcoin ETFs saw $223.5 million in net inflows, led by BlackRocks IBIT at $192.9 million and Fidelity at $30.6 million daily inflow of $223.5 million.
Earlier in the week, daily flows were mixed, with IBIT showing resilience on a down day (Dec 8 inflow $28.76 million) amid broader BTC ETF net outflows mixed flows snapshot.
On a weekly basis, Bitcoin ETPs led all crypto funds with $352 million in inflows, while short?Bitcoin products saw outflows, hinting at waning bearish bets weekly summary.
Bitcoin remains the primary inflow magnet, but issuer?level leadership (IBIT vs FBTC) can flip day to day; monitoring daily prints helps track momentum and breadth of demand.
2. Ethereum Inflows
Spot Ethereum ETFs recorded their largest single?day inflow in six weeks at $177.64 million on Dec 9, surpassing BTC ETFs that day. Issuer breakdown: Fidelity $51.47 million, Grayscale $45.19 million, BlackRock $35.29 million six?week high inflow.
Cumulatively, BlackRocks ETHA remains the largest ETH ETF by net inflows ($13.09 billion) and AUM, with Fidelitys FETH at $2.62 billion total inflows issuer totals.
Weekly totals across all crypto funds still favored BTC, but ETHs strong single?day print indicates rotation and selective risk appetite into ETH exposure weekly summary.
ETH flows suggest institutions are broadening beyond BTC; days when ETH outpaces BTC often coincide with narrative catalysts or issuer distribution opening.
3. Altcoin ETF Rotation
XRP ETPs led altcoin inflows last week with $245 million, marking the strongest week of the year and highlighting broadening demand XRP leadership.
Chainlink products posted a record $52.8 million weekly inflow, about 54% of LINK AUM, an unusually high ratio for a single week record LINK inflow.
Solana saw consistent gains in several sessions and a reported $16 million weekly print in one roundup, reflecting ongoing interest in non?BTC, non?ETH exposure altcoin weekly context.
Altcoin ETF demand is diversifying. Attention rotates toward specific narratives (utility, infrastructure, staking), which can drive concentrated weekly inflows in non?BTC assets.
Conclusion
Inflows this week were led by Bitcoin on aggregate, but single?day leadership rotated: ETH dominated on Dec 9, and BTC surged on Dec 10. Altcoin ETPs, especially XRP and Chainlink, saw meaningful weekly prints. Tracking issuer?level daily flow leaders and asset?level weekly summaries offers the clearest read on where institutional demand is concentrating now.
