BlackRock’s IBIT Enters Top 20 ETFs by Assets, Sees Biggest Inflow Since Mid-August

Farside data shows that bitcoin U.S. exchange-traded funds (ETFs) recorded their largest inflow since Sept. 10, with $675.8 million. BlackRock’s iShares Bitcoin Trust (IBIT) captured the majority, taking in $405.5 million, it’s biggest inflow since Aug. 14 and pushing its total net inflows to $61.376 billion. The surge coincided with bitcoin climbing over $119,000, a 4% gain on the day.

According to Bloomberg Senior ETF Analyst Eric Balchunas, IBIT has entered the top 20 ETFs by assets for the first time, reaching $90.7 billion. Since launching in January 2024, IBIT is up 175%.

Balchunas noted that IBIT entering the top 10 ETFs by assets may not be far off, setting December 2026 as a potential target. “Someone asked me how long till Top 10. It is $50 billion away. If the last 12 months are repeated, it may not take long. It took in $40 billion over the past year and gained 85%. That said, those other ETFs are growing too so I don’t know. If forced, I’d set the over/under for Christmas 2026,” Balchunas said.

On Wednesday, bitcoin’s 4% rise came just short of a top 10 daily performance in 2025. Data from Velo shows that Wednesday has been, on average over the past year, the most bullish day for bitcoin, while Thursday has been the most bearish.
