In the Ethereum ecosystem, every move by major capital players can influence market sentiment. According to on-chain data monitoring, a well-known treasury holding over 4 million ETH recently initiated a staking plan—this marks their first attempt so far.

Specifically, in their latest transaction, they deposited 74,880 ETH into the Ethereum PoS staking contract, which is approximately $2.19 billion at current prices. This not only reflects large institutional interest in PoS staking yields but also suggests that more long-term holders may begin to participate in staking, shifting from passive holding to active income generation.

Considering the current Ethereum staking yield of about 3.12%, if such a large treasury fully activates staking, the annualized return would be a significant figure. This trend could also impact the liquidity landscape of ETH—more ETH being locked means further reduction in market circulation. For investors focused on the Ethereum ecosystem, monitoring the fund flows of these whale-level holders often provides early insights into market dynamics.
