BlackRock Bitcoin Purchase Pushes IBIT Toward $100B Milestone

BlackRock bitcoin purchase has made another massive entry in the crypto market. The world's largest asset manager has purchased nearly $1 billion ($969.95 million) in BTC, its third-largest purchase after it started its Bitcoin ETF.

This massive buy has pushed BlackRock’s iShare Bitcoin Trust (IBIT) closer to reaching a historic $100 billion in assets, something no bitcoin-ETF has ever done before.

IBIT Becomes BlackRock’s Top-Earning ETF

IBIT has grown at an unbelievable speed. In less than two years, it has become BlackRock’s most profitable ETF .

The fund now holds over 769,000 BTC, worth more than $95 billion at current prices. The firm earns a 0.25% fee on this, which equals around $244.5 million in yearly revenue.

To compare, the popular Vanguard S&P 500 ETF took more than 2,000 days to reach $100 billion. IBIT is about to hit that number in under 450 days, making it the fastest-growing ETF in history.

Other Big Players Are Buying Too

The asset manger isn’t alone. Fidelity and Bitwise also bought a combined $172.3 million worth of BTC recently. Together with BlackRock, that’s over $1.1 billion in fresh institutional BTC buying activity in just days.

What’s interesting is that they are buying even as Bitcoin-trades near its all-time highs. This shows that institutional investors still have strong confidence in bitcoin-future growth.

Bitcoin Hit ATH – Yet Institutions Keep Buying

BTC is currently trading around $124,000–$125,000, just below its all-time high of $126,198.07 on October 7. Normally, you’d expect big investors to wait for dips or take profits at this level. Instead, they’re buying aggressively.

Why?

• ETF Inflow: Spot Bitcoin-ETFs registered $3.2B of net inflows last week, the biggest so far in 2025 and second-largest on record. BlackRock-IBIT topped with $1.78B.

• Long Term Perspective: Institutions are not seeking short-term maneuvers; they're placing Bitcoin-as a long term anchor asset with continuously rising prices.

• Macro Factors: With U.S. rate cuts likely and regulatory clarity improving, this could mark the start of a new accumulation cycle.

What This Mean and What Could Happen Next

Where the currency is gaining more strong confidence, ETFs are becoming mainstream investment vehicles. With this continuous whale buying at ATH level could extend the bull cycle, attracting retail FOMO. If ETF-driven demand keeps rising, bitcoin’s supply shock post-halving could push prices to new heights by the end of the year.
