On Monday, August 5, 2024, spot Bitcoin exchange-traded funds (ETFs) in the United States experienced significant capital outflows, totaling $168.44 million. The day's activity stood in sharp contrast to their Ethereum ETF counterparts, which saw inflows. The outflows were predominantly concentrated in three major funds.
Grayscale GBTC, ARKB, and FBTC Lead the Decline
Data from sosovalue.xyz and Coinglass reveals that Grayscale’s Bitcoin Trust (GBTC) recorded a net outflow of $69.12 million, bringing its cumulative net divestments since its launch on January 11, 2024, to a staggering $19.13 billion. The Ark Invest and 21shares ARKB fund followed closely, shedding $69 million on the day. Fidelity’s FBTC also saw a notable decrease of $58.04 million. Together, these three funds accounted for the majority of Monday’s net outflows.
Select Funds Buck the Trend
Despite the overall negative sentiment, a few Bitcoin ETFs managed to attract capital. Grayscale’s Mini Bitcoin Trust (ticker: BTC) gained $21.81 million, pushing its total net inflows since its debut to $240.81 million. VanEck’s HODL ETF added $3 million, and Bitwise’s BITB absorbed $2.9 million. Meanwhile, BlackRock’s IBIT, along with BRRR, BTCO, EZBC, BTCW, and DEFI, reported no net change for the day.
Cumulative Performance and Market Scale
Since the launch of the first spot Bitcoin ETFs in January 2024, the 12 funds have accumulated a combined $17.34 billion in cumulative net inflows. IBIT remains the dominant player, with cumulative inflows of $20.10 billion. At the other end of the spectrum, the Hashdex DEFI spot Bitcoin ETF has recorded the smallest cumulative inflows, just $2.1 million. As of August 6, 2024, these ETFs collectively hold $48.43 billion in Bitcoin reserves, representing approximately 4.51% of Bitcoin’s total market capitalization. Monday's trading volume reached $5.24 billion, indicating robust market activity.
Market Context and Outlook
The outflows occurred against a backdrop of heightened global market volatility, with Bitcoin’s price experiencing notable swings on Monday. Analysts attribute the capital exodus primarily to Grayscale’s relatively high fee structure and broader risk-off sentiment among investors. However, the inflows into lower-cost funds like Mini BTC, HODL, and BITB suggest that institutional demand for long-term Bitcoin exposure remains intact. Market participants will closely watch whether the flow trend reverses as sentiment stabilizes. Overall, the spot Bitcoin ETF ecosystem continues to mature, offering both retail and institutional investors regulated exposure to the digital asset.
