BlackRock IBIT Swallows Nearly 5,000 BTC as Bitcoin Price Tops $110,000

Bitcoin price shot to a fresh all-time high late on May 21, 2025, with Blackrock IBIT scooping up nearly 5,000 BTC in one day. TradingView data shows BTC price hit $111,600 on Coinbase, breaking above its previous peak.

The rally came amid a sharp U.S. market sell-off (a weak Treasury auction on May 21 sent yields spiking and stocks tumbling), suggesting Bitcoin’s advance was driven by its momentum and institutional demand.

Indeed, analysts note that this new high reflects “a mature interest in digital assets” supported by institutional-grade infrastructure and clarity.

BlackRock ETF Sees Record Inflows

BlackRock’s spot Bitcoin fund, the iShares Bitcoin Trust (IBIT), drew unprecedented investor interest on May 21. According to Farside Investors data, IBIT took in $530.6 million that day – its largest single-day net inflow since the $531.2M intake on May 5.

This net investment equated to roughly 4,931 BTC. To put that in perspective, Bitcoin miners produced only about 450 BTC over the same 24‑hour period, so IBIT bought more than ten times the daily issuance.

Notably, IBIT has not recorded a net outflow since April 9, marking at least 20 consecutive trading days of inflows into the fund. In short, BlackRock’s ETF is consistently attracting fresh capital even as Bitcoin rallies.

The IBIT inflow was by far the largest on May 21, but demand was broad-based across U.S. spot Bitcoin ETFs. In total, U.S. spot Bitcoin ETFs saw about $607.1 million of net inflows.

After IBIT’s $530.6M haul, the next biggest contribution came from Fidelity’s Wise Origin Bitcoin Fund (FBTC), which took in roughly $23.5 million.

Other funds saw much smaller moves: Bitwise’s BITB raised about $20.5M and ARK Invest’s ARKB about $4.3M, while some newer or smaller products reported essentially zero flows.

These figures underscore that the inflow was overwhelmingly concentrated in the largest ETFs, led by IBIT and followed distantly by FBTC.

Soaring Volume and Analyst Views

Data shared by the Twitter/X account Trader T (an ETF tracking source) showed that IBIT’s one-day volume on May 21 was the highest since January.

ETF Store president Nate Geraci commented on the heavy trading, observing, “Given trading volume today, expect these inflow numbers to increase”.

Bloomberg ETF analyst Eric Balchunas likewise remarked that the scene resembled a “classic feeding frenzy” around Bitcoin’s price rally. Balchunas noted that ETF subscriptions were running at roughly twice their average daily pace, and at levels not seen since Bitcoin’s last peak in January.

These data-driven signals – record ETF inflows, blockbuster trading volume, and Bitcoin’s new record price – paint a clear picture of institutional demand.

The convergence of a fresh all-time high price and huge ETF subscriptions suggests a strong underlying appetite for Bitcoin via regulated channels.

As one analyst put it, all major Bitcoin ETFs are seeing inflows far above their historical norms. This confluence of price and flows may continue to support Bitcoin’s momentum, barring major changes in macro or regulatory conditions.
