Bitcoin ETFs see largest daily inflows since Trump election surge as BlackRock's IBIT nears $100 billion in AUM

The U.S. spot bitcoin exchange-traded funds topped $1 billion worth of net inflows on Monday for the first time since July 11 as the foremost cryptocurrency marked its latest all-time high of $126,296.

BlackRock's IBIT dominated the inflows with $970 million, followed by Fidelity's FBTC with $112.3 million, Bitwise's BITB with $60.1 million, and Grayscale's BTC with $30.6 million, according to data compiled by The Block.

Overall, the funds attracted their second-largest ever daily inflows, totaling $1.21 billion. The record $1.37 billion daily haul for the bitcoin ETFs was set on Nov. 7, 2024, just after pro-crypto Donald Trump won the U.S. presidential election.

Trading volume was also elevated amid the price rise, with IBIT accounting for $4.9 billion of the $6.5 billion in trading activity on Oct. 6, per The Block's data dashboard .

Meanwhile, the U.S. Ethereum ETFs saw net inflows of $181.8 million on Monday, again led by BlackRock's ETHA product with $92.6 million, adding to a six-day positive streak totalling nearly $1.5 billion.

BlackRock's IBIT closes in on $100 billion in AUM

Ahead of Monday's flow data, Bloomberg Senior ETF analyst Eric Balchunas noted that BlackRock's IBIT is swiftly closing in on $100 billion in total assets under management.

"IBIT a hair away from $100 billion, is now the most profitable ETF for BlackRock by a good amount now based on current AUM," Balchunas posted on X. "Check out the ages of the rest of the Top 10. Absurd." IBIT tops the list of BlackRock's funds by annual revenue, beating out juggernauts like its S&P 500, Russell 1000, and Gold ETFs.

As of Oct. 3, IBIT held 783,767.84 BTC, according to its official fund page . Monday's addition of approximately 7,860 BTC takes that total to around 791,628 BTC — worth $99.98 billion at yesterday's all-time high and $98.31 billion at bitcoin's current price of $124,190, according to The Block's BTC price page .

Cumulatively, the spot bitcoin ETFs have taken in around $61.5 billion in net inflows since their January 2024 launch and now have a total of nearly $170 billion in AUM amid the concurrent price rise.

BlackRock's bitcoin fund will almost certainly become the fastest ETF to hit the $100 billion AUM milestone, trouncing the current record holder VOO's 2,011 days compared to IBIT's 435 days so far. "Only 18 of 4,500+ ETFs have > $100 billion in AUM," NovaDius Wealth Management President Nate Geraci added . "First ETF launched in 1993, so we're talking 30+ years of history."

'Structurally sound' bitcoin rally

"Bitcoin’s 2025 rally now ranks among the most structurally sound in its history, with reduced leverage, cleaner positioning, and sustained real demand. ETF data, on-chain signals, and technicals all point to strength, but short-term overheating risks remain," BRN Head of Research Timothy Misir told The Block following Monday's latest peak.

"Momentum remains robust, but shorter-term indicators suggest mild overextension. A brief consolidation between $123,000–$126,000 would be healthy before the next leg higher toward $130,000–$135,000," he said.
