US Bitcoin ETFs Shatter Records with $2B Weekly Inflow—Is the Bull Run Back?

Wall Street's bitcoin bet just got serious—again.

US Bitcoin ETFs Rake in Massive Capital

Exchange-traded funds tracking bitcoin just pulled in over $2 billion in a single week. That kind of cash doesn't move quietly—it’s institutional money making a statement. BlackRock, Fidelity, and the usual suspects are back at the table, and they’re hungry.

What’s Driving the Surge?

Maybe it’s the macro mood. Maybe it’s fear of missing out on the next leg up. Or maybe—just maybe—traditional finance is finally realizing crypto isn’t a sideshow. Either way, flows like these don’t lie. They shout.

Not everyone’s convinced, of course. Plenty of suits still think digital gold is just digital fool’s gold—right up until their own fund starts underperforming.

So is the appetite back? When $2 billion walks in the door in seven days, that’s not a question—it’s an answer.

Bitcoin ETFs Close Week With $642-M Inflow

According to the latest market data, the US-based bitcoin ETFs posted a total net inflow of $642.35 million on Friday, September 12. This single-day performance marked the fifth consecutive day of positive capital influx for the exchange-traded funds.

Surprisingly, Fidelity Wise Origin Bitcoin Fund (with the ticker FBTC) led the pack on Friday, closing the week with a net inflow of over $315 million. Meanwhile, BlackRock’s iShares Bitcoin Trust (with the ticker IBIT) came in second with a daily net inflow of $264.71 million on Friday. This impressive daily performance pushed the largest Bitcoin exchange-traded fund closer to reaching a net assets valuation of $90 billion.

Bitwise Bitcoin ETF (BITB) with a $29.16 million net inflow and ARK 21Shares Bitcoin ETF (ARKB) with a $19.37 million net inflow also added value in double digits on Friday. Grayscale Bitcoin Mini Trust (BTC) and VanEck Bitcoin ETF (HODL) were the only Bitcoin ETFs that recorded any activity, with $5.69 million and $8.24 million, respectively, on the day.

As inferred earlier, Friday’s $642-million performance was only the latest in a line of strong performances by the US-based Bitcoin ETFs. The latest market data shows that the BTC exchange-traded funds added $2.34 billion in value over the past week.

This past week’s performance represents the first time that the Bitcoin ETFs would be crossing the billion-dollar mark on the inflow chart. Also, the BTC-linked investment products outperformed the US Ethereum ETF market, which closed the week with a net weekly inflow of $637.69.

Bitcoin Price At A Glance
