Why has BTC accumulation outpaced ETH recently?
BlackRock’s BTC accumulation accelerated from about 698K BTC to 740K BTC over the past two months (~6% increase), reflecting stronger investor demand for Bitcoin-focused ETF exposure. In contrast, ETH flows were weaker late in Q3, with notable outflows from Ethereum products.
What recent ETH flows have been reported?

Net assets fell from over $17B to about $15.9B amid the outflows and a pullback in ETH price.

How could ETH ETF staking approval change demand?
Approval of staking for ETH ETFs would likely raise demand by enabling yield-generation within ETF wrappers, attracting yield-seeking institutional capital. Staking permission could narrow the yield differential between native staking and ETF exposure, boosting institutional appetite for ETH products.
