BlackRock-Linked Bitcoin Outflows Hit 10,000 BTC As ETF Pressure Builds

BlackRock-linked Bitcoin wallets saw more than 10,000 BTC leave over the past two days, worth roughly $780 million, as spot Bitcoin ETF redemptions added pressure to an already weak market.

The movement matched a sharp outflow window for BlackRock’s iShares Bitcoin Trust. IBIT recorded $448.4 million in net outflows on May 18 and another $325.6 million on May 19, bringing the two-day total to about $774 million. At Bitcoin’s current price near $77,500, that is roughly in line with the 10,000 BTC-plus figure circulating from BlackRock-linked wallet data.

The flow points to ETF redemptions and fund-linked custody movement rather than a confirmed discretionary sale by BlackRock from its own balance sheet. Spot Bitcoin ETF redemptions can send BTC out of custody channels when shares are redeemed, putting the pressure on fund demand and settlement flows instead of a simple “BlackRock sold” headline.

IBIT has been the strongest institutional demand engine of the spot Bitcoin ETF cycle, so a two-day redemption window near $774 million lands hard while BTC is already fighting to hold the mid-$70,000 area. Traders now have to watch whether this becomes a short redemption pocket or the start of a deeper cooldown in ETF demand.

ETF Redemptions Add To Bitcoin’s Weak Tape

Bitcoin traded near $77,500 on May 20, holding above the intraday low near $76,180 but still below the levels bulls needed to reclaim after the latest reset. The market has been trying to stabilize after a run of ETF outflows, weaker liquidity and heavy liquidation pressure.

The broader U.S. spot Bitcoin ETF market has also been under pressure. Total ETF outflows reached $648.6 million on May 18 and another $331.1 million on May 19, leaving two consecutive sessions of redemptions across the category. BlackRock’s IBIT accounted for most of the two-day pressure, with its $774 million combined outflow dominating the daily totals.

That reverses the stronger ETF-demand narrative that supported Bitcoin during earlier parts of the cycle. Recent Bitcoin ETF outflow coverage already showed the market breaking a six-week inflow streak as BTC slipped below the $79,000 area. The latest BlackRock-linked outflows extend that pressure and keep attention on whether ETF demand is rotating, cooling, or turning into a broader de-risking wave.

Institutional Demand Becomes The Main Test

The latest outflows do not mean institutional Bitcoin exposure has vanished. IBIT remains one of the largest spot Bitcoin ETFs in the market, and short-term redemptions can happen even inside dominant funds. The problem for BTC is timing. Large outflows are arriving while traders are already watching macro pressure, weaker liquidity and fragile support near the mid-$70,000 area.

Recent crypto liquidity data showed capital entering the market at a slower pace, reducing the cushion that helped absorb selling earlier in the cycle. ETF redemptions make that setup harder because spot Bitcoin funds have been one of the clearest channels for institutional demand.

The next signal is whether IBIT outflows slow or continue through the rest of the week. A quick stabilization would frame the two-day move as a sharp redemption pocket inside a still-large fund. Another wave of redemptions would put the market back on the defensive, especially if Bitcoin fails to reclaim $78,000 and ETF outflows keep pulling coins out of fund-linked custody channels.

BlackRock-linked wallet outflows now sit at the center of the Bitcoin tape. The market does not need to treat them as confirmed open-market selling, but it cannot ignore the message either: the strongest ETF demand engine of the cycle is no longer adding pressure to the upside, and BTC needs fresh spot buying to absorb the redemption flow before support near $76,000 faces another test.
