Bitcoin Spot ETFs Log $5.3 Billion in Weekly Inflows as BTC Surges Above $120K

Bitcoin’s ETF bonanza rolls on this week, pushing markets higher even as traders warn the rally could pause. For the seventh straight day, spot Bitcoin exchange-traded funds logged net inflows on October 7, taking in roughly $876 million in a single session and helping to push the asset toward fresh highs this week.

The steady stream of cash into U.S. spot Bitcoin products has been a key engine behind the rally, with market-watchers counting more than $5.3 billion poured into Bitcoin ETFs across the last seven trading days, a figure that has become a talking point on trading desks and in ETF commentary.

Ethereum’s Wall Street moment has arrived alongside Bitcoin’s. U.S. spot Ether ETFs also enjoyed a sizable intake on October 7, recording about $421 million in net inflows and extending their own seven-day streak of positive flows. That pickup in demand for ETH through regulated vehicles has coincided with on-chain signs of strong accumulation and shrinking exchange reserves, a combination analysts say can amplify upside when buyers remain patient.

The money has shown up in prices. Bitcoin briefly hit new record territory earlier in the week, topping roughly $125,000, before settling back into the low-$120,000s as profit-taking and a firmer dollar weighed on sentiment. The week’s price action has looked like classic “news meets flows”: heavy ETF demand pushes prices higher, traders lock in gains, and headlines about macro moves (and occasional government headlines) set the next tone.

How Big is the ETF Contribution?

Data aggregators that track U.S. spot Bitcoin funds show the week ending early October was one of the largest for inflows, with approximately $3.24 billion pouring into U.S. spot BTC ETFs in the most recent seven-day window, a near-record weekly total for the products.

At the same time, other trackers who sum slightly different date ranges have pointed to the roughly $5.3 billion figure across the last seven trading days, showing just how concentrated and rapid these flows have been. Either way, the takeaway is the same: institutions are using ETFs to deploy big capital quickly.

What this means technically and for investors is nuanced. ETF inflows remove supply from the market (funds buy spot Bitcoin and Ethereum), which tightens the available float and supports higher prices if demand persists. For Ethereum, reduced exchange balances and the new ETF vehicles acting as steady buyers have prompted some firms to lift price targets.

Citigroup, for example, recently raised its year-end ETH outlook, citing stronger institutional demand. But markets remain vulnerable to normal pullbacks: a stronger U.S. dollar or a shift in macro expectations can trigger rapid profit-taking, and the record highs seen this week were followed by a modest retreat as traders took chips off the table.

Looking ahead, traders will be watching three things: whether ETF inflows remain sustained (large single-day inflows have a way of concentrating momentum), on-chain supply metrics such as exchange reserves, and macro headlines that can flip risk appetite in a hurry. For now, the script is simple: institutional money is piling in via ETFs, that buying pressure has helped lift both BTC and ETH into new price neighborhoods, and market participants are wrestling with how much of the move is structural demand versus short-term momentum.
