In the fast-paced world of crypto, big moves by institutional giants like BlackRock often send ripples through the market. Today, on-chain data sleuths spotted something intriguing: BlackRock depositing a whopping 12,000 ETH—valued at around $48.6 million—into Coinbase Prime over the span of just 40 minutes.

This activity was first highlighted in a tweet by @OnchainLens, a popular account dedicated to simplifying on-chain data for everyday users. The post links to Arkham Intelligence's explorer page for BlackRock, where you can dive deeper into their wallet movements.

この入金は何を意味するのか？

For those new to the scene, BlackRock runs the iShares Ethereum Trust ETF (ETHA), a spot ETF that tracks the price of Ether (ETH), the native cryptocurrency of the Ethereum blockchain. Coinbase Prime serves as the custodian for these assets, meaning it's where BlackRock parks the actual ETH backing the ETF shares.

When BlackRock deposits ETH into Coinbase Prime, it's often a sign of net inflows into the ETF. In simple terms, more investors are buying shares of ETHA, requiring BlackRock to acquire and deposit additional ETH to maintain the fund's balance. This particular deposit came in four chunks of 3,000 ETH each, executed within minutes of each other.

Looking at recent data, Ethereum spot ETFs have seen volatile flows in October 2025. Some weeks showed strong inflows, like $488 million in one period led by BlackRock's ETHA with $638 million. However, the latest reports indicate a shift, with net outflows of $312 million last week, including $245 million from ETHA alone. This deposit could signal a rebound or delayed settlement from previous positive flows.

One reply to the tweet pointed out "T+1 settlement," suggesting these deposits might reflect Friday's (October 17, 2025) ETF inflows settling on Monday. In traditional finance, T+1 means trades settle one business day after execution, which could explain the timing.

BlackRock's moves aren't just about ETH—they reflect growing institutional interest in crypto. With their Bitcoin ETF (IBIT) also showing massive holdings (over 774,000 BTC), this underscores how traditional finance is embracing digital assets.

For meme token enthusiasts, this is potentially bullish. Many popular memes like PEPE or DOGE run on the Ethereum network or benefit from its liquidity. Strong ETF inflows could pump ETH's price, creating a rising tide that lifts altcoins and memes. If ETH breaks key resistance levels around $4,000, as some analysts predict, it might spark a meme coin rally.
