Bitcoin Price Hits All-Time High as BTC ETFs See Second-Largest Weekly Inflows

Highlights:

• Bitcoin treasury firms bought $1.2 billion last week, led by Metaplanet investors.
• The recent Bitcoin price surge was mostly fueled by $3.24 billion inflows into ETFs.
• Major investors continue accumulating Bitcoin, signaling growing institutional confidence in cryptocurrency markets.

Last week, Bitcoin treasury firms purchased $1.2 billion in BTC, led by major investors including Japan’s Metaplanet. However, analysts say the recent price surge was mainly driven by inflows into Bitcoin exchange-traded funds (ETFs). Over the weekend, Bitcoin soared past $125,000, marking a new all-time high. 

U.S. spot Bitcoin ETFs attracted $3.24 billion last week, marking their second-largest weekly inflow since they launched in January last year. According to SoSoValue data, only the week ending November 22 saw larger inflows of $3.38 billion. The recent rebound reversed the prior week’s $902 million outflows and brought total inflows over the past four weeks close to $4 billion.

BlackRock’s iShares Bitcoin Trust, commonly called IBIT, led last week’s inflows, capturing $1.8 billion of the total net additions. The fund now oversees $96.2 billion in assets, strengthening its position well ahead of competitors. Meanwhile, Fidelity’s FBTC, ranked as the second-largest fund by net asset value, recorded inflows of $692 million last week. This amount accounted for roughly 38% of IBIT’s total, underlining BlackRock’s clear dominance in the Bitcoin ETF sector.

ETF experts highlighted huge inflows into spot BTC ETFs. Nate Geraci called the second-largest weekly inflow “ridiculous,” noting net inflows have exceeded $60 billion since launch. Eric Balchunas added that Bitcoin hit all-time highs after $3.3 billion flowed into ETFs in a single week.

Bitcoin hit ATHs last night after the ETFs went wild last week with +$3.3b in a week, $24b for year (also notable $IBIT and $ETHA w $10b for month, rank 3rd and 4th overall) and now $60b lifetime (new high water mark). Pretty good. No way @WhalePanda can still be pissed, right? pic.twitter.com/xHH3yjp4U7

Bitcoin ETFs Outperform Treasuries and Small Traders

The most bullish sign of Bitcoin’s new all-time high is that it was driven by spot ETF purchases rather than treasury companies or high-risk traders. Macro portfolio managers and funds are increasingly seeing Bitcoin as a rotation from commodities and small-cap stocks. Bloomberg ETF analyst James Seyffart confirmed strong holdings in several Bitcoin and Ethereum ETFs. He noted that spot BTC ETFs are likely to continue outperforming spot Ethereum ETFs as long as net inflows remain positive.

Corporate and ETF Holdings Reflect Growing Market Adoption

Crypto analyst and trader Will Clemente III highlighted ETF inflows as a key driver for Bitcoin’s recent surge in a Sunday X post. He noted, “Possible we get one last dip, but the most bullish thing about this move on Bitcoin is that it wasn’t driven by treasury companies or perp degens, it was driven by spot ETF buying — which is likely macro PMs and funds viewing BTC as a rotation from commodities & small caps.”

Strategy executive chairman and BTC supporter Michael Saylor predicted in September that Bitcoin would start gaining momentum again toward the end of the year, fueled by growing corporate and institutional interest. According to Bitbo, ETFs currently hold more than 1.5 million Bitcoin valued at $188 billion, representing 7.2% of the total supply. Meanwhile, corporate Bitcoin treasuries now exceed 1.4 million coins, worth over $166 billion, accounting for 6.6% of the total supply.
