Spot Bitcoin ETFs attract $1.42B in strongest week since early October

Spot Bitcoin ETFs just pulled in $1.42B in net inflows this past week — the biggest weekly haul since early October. Institutional money is flooding back in, and the vibes are shifting.

Data from SoSoValue shows inflows peaked midweek: Wednesday saw a massive $844M single-day inflow (the largest ever), followed by $754M on Tuesday. Even with a $395M outflow on Friday, the weekly total still hit $1.42B — the strongest since October's $2.7B surge.

Ether ETFs also got love early in the week: Tuesday saw ~$290M inflow, Wednesday ~$215M. But Friday had ~$180M in outflows, trimming the weekly gain to ~$479M.

Vincent Liu, CIO at Kronos Research, says this pattern screams long-only allocators are back via regulated channels. "ETF absorption alongside whale stabilization implies tightening effective supply and a more risk-on market environment."

On-chain data shows whales have dialed back net selling compared to late December — easing distribution pressure. Combine that with steady ETF buying, and you get a market where supply is tightening even with price volatility.

But Liu cautions: "This is an early phase of the shift, rather than full confirmation." Renewed inflows + reduced whale selling + improving market structure = a more durable institutional bid forming under the market. "Odds point to more green days, though not in a straight line. ETF inflows are providing a structural bid while easing whale selling suggests dips are more likely to be absorbed."

According to Bitcoin macro intelligence newsletter Ecoinometrics, recent ETF inflow spikes have triggered short-lived price rebounds — gains fade once inflows slow.

The takeaway: Bitcoin needs several consecutive weeks of strong ETF demand to shift the broader trend. Cumulative ETF flows are still deeply negative. Isolated positive days might stabilize prices, but without sustained inflows, don't expect a lasting uptrend.
