Spot Bitcoin ETFs (exchange-traded funds) recorded a fresh daily net inflow of 1,740 BTC, equal to $145.71 million, according to on-chain analytics shared on Monday, September 28, 2026.
Over the prior seven days, the same products absorbed 29,298 BTC, or roughly $2.45 billion.
These figures arrive at a time when Bitcoin has pulled back from recent highs, yet institutional demand through regulated vehicles continues to build.
In the meantime, the parallel Ethereum ETF complex also posted positive flows, though Bitcoin remains the clear leader in absolute capital attracted.
What Do the $145.7M Daily Bitcoin ETF Inflows Actually Represent?
Daily creations of that size mean authorised participants are delivering cash or Bitcoin to the funds in exchange for new shares.
BlackRock’s IBIT has consistently captured the largest share of such activity throughout 2026, with Fidelity’s FBTC and a handful of smaller products following.
Beyond the headline dollar number, the 1,740 BTC added in a single session increases the total Bitcoin held across U.S. spot products and tightens available supply on the open market.
Why Have Bitcoin ETFs Drawn $2.45B in Just One Week?
The seven-day total ranks among the stronger weekly hauls of 2026 and follows a stretch of consecutive inflow days that began in mid-September.
Meanwhile, price volatility has not deterred buyers; instead, many appear to treat dips as entry points.
In addition, year-to-date (YTD) flows for the category have swung from deep negative territory earlier in the summer back into positive territory after successive weeks of net buying.
At the same time, the products continue to serve as the primary on-ramp for traditional finance (TradFi) capital that prefers brokerage accounts over self-custody.
Next, the sheer size of the weekly figure—nearly $2.5 billion—shows that demand is broad rather than confined to a single large ticket.
How Do Sustained Bitcoin ETF Inflows Affect Broader Market Dynamics?
When net creations persist, the funds must acquire Bitcoin in the spot market, creating a structural bid.
Still, one day or even one week of inflows does not dictate price direction on its own; longer streaks matter more.
That said, the current seven-day run of positive flows, coming after periods of heavy redemptions earlier in 2026, signals a measurable shift in sentiment among institutional allocators.
Furthermore, the cumulative holdings across the twelve U.S. spot Bitcoin ETFs now represent a material percentage of circulating supply.
Also worth noting is that, fee competition remains intense, with several products charging 0.20–0.25%, keeping the vehicles attractive relative to older trust structures.
In short, the latest data from Lookonchain and corroborating trackers underline that Bitcoin ETFs remain a dominant channel for capital entering the asset class.
While daily numbers will fluctuate, the $2.45 billion weekly total reinforces the products’ growing role in institutional portfolios.
