BlackRock IBIT Bitcoin ETF inflows surge to $983M weekly high
BlackRock’s iShares Bitcoin Trust (IBIT) recorded a $983M weekly net inflow—the largest single-week Bitcoin ETF demand in six months—per CryptoQuant’s Ki Young Ju. This follows the earlier 2024 SEC spot Bitcoin ETF approval wave and signals renewed institutional risk appetite.
IBIT remains the largest spot Bitcoin ETF by assets and continued to outpace peers. In the cited flow breakdown, IBIT added $983M, while Fidelity’s FBTC gained $312M and ARK 21Shares’ ARKB rose $150M. Bitwise’s BITB added $88M, while Grayscale’s GBTC saw -$45M net outflows, suggesting investors may be rotating from higher-fee structures toward lower-cost ETF exposure.
The inflow coincided with a broader rebound: BTC gained about 12% in the same week and reclaimed the ~$70,000 level. CryptoQuant’s on-chain read is that the buying is driven by registered investment advisors and pension funds, with coins moving to cold storage—potentially reducing exchange-available supply.
For traders, sustained BlackRock IBIT inflows can act as near-term support if BTC holds key breakout levels. However, earlier estimates also flagged large unrealized losses for ETF holders (paper losses cited at roughly $12B, with an average cost basis near ~$89,000 vs. spot). If ETF inflows slow while BTC stalls, selling pressure could re-emerge.
Bullish
The latest update shows BlackRock IBIT hit a $983M weekly inflow, the biggest since early-2024. That kind of persistent ETF demand typically supports BTC by reinforcing “institutional bid” narratives and by potentially moving coins toward cold storage, reducing readily available sell liquidity. It also coincided with BTC reclaiming ~$70k and a ~12% weekly rise, aligning flows with price momentum—traditionally bullish for continuation trades.
The main limiting risk is that earlier commentary highlighted large unrealized losses for ETF holders (paper losses around ~$12B). If IBIT inflows fade while BTC stalls, holders could become more sensitive to selling, weakening the near-term bid. Overall, though, the direction and magnitude of the new inflow data outweigh that risk for BTC itself in the near term.
