Fund inflows set a second consecutive record
Digital-asset investment products attracted a record $2.9 billion during the week ended March 15, 2024, according to a CoinShares report published on March 18, 2024. The total exceeded the preceding week’s record of $2.7 billion and lifted reported net inflows for 2024 through March 15 to $13.2 billion.
That year-to-date amount had already surpassed the $10.6 billion CoinShares recorded for all of 2021. The comparison mattered because it showed how quickly capital was entering regulated or professionally managed crypto products after U.S. spot bitcoin exchange-traded products began trading in January. It did not establish that every dollar represented a new cryptocurrency buyer or a direct open-market bitcoin purchase.
This article is a 2026 reconstruction of the record available on March 18, 2024, not a recovered copy of an earlier Coinburn article.
Bitcoin dominated the measured demand
Bitcoin investment products accounted for $2.86 billion of the weekly inflow. CoinShares also reported that bitcoin products represented 97% of all digital-asset product inflows for the year through March 15. The 97% figure describes bitcoin’s share of year-to-date net flows in CoinShares’ dataset; it is not bitcoin’s share of the cryptocurrency market or of all institutional portfolios.
The asset breakdown was notably uneven. Products offering short-bitcoin exposure received $26 million, their fifth consecutive week of inflows. Ethereum products recorded $14 million of outflows, while Solana and Polygon products lost $2.7 million and $6.8 million respectively. Blockchain-equity products received $19 million, ending a six-week sequence of outflows in that category.
Geographically, the United States contributed $2.95 billion of inflows. Australia, Brazil and Hong Kong added $5 million, $24 million and $15 million. Those additions were partly offset by a combined $78 million of outflows from Canada, Germany, Sweden and Switzerland. The figures demonstrate why the worldwide total can be lower than the U.S. contribution: CoinShares reported net flows after combining positive and negative country observations.
The exchange-traded channel had become consequential
CoinShares put weekly trading volume in the covered investment products at $43 billion, matching the record it reported for the preceding week. Its analysis estimated that this represented 47% of overall global bitcoin trading volume during the measurement period. Global assets under management in the products crossed $100 billion during the week before a price correction left the closing figure at $97 billion.
These measurements captured a broader universe than the new U.S. spot bitcoin funds alone. CoinShares compiled flows across digital-asset investment products in multiple countries and included long, short and blockchain-equity categories. The $2.9 billion total therefore should not be described as a U.S. spot-ETF-only number.
The institutional context was nevertheless clear. On January 10, 2024, the Securities and Exchange Commission approved exchange rule changes permitting several U.S. spot bitcoin ETP shares to list and trade. By March 18, the new channel had helped concentrate measured product demand around bitcoin and the United States. The SEC’s order authorized listings under securities-market rules; it did not approve bitcoin itself or guarantee the products’ performance.
What the report could not establish
Fund-flow estimates are not the same as exchange trading volume, assets under management or cryptocurrency returns. Creations and redemptions may involve market makers, transfers from other vehicles, portfolio reallocations or operational inventory. CoinShares also cautioned that its information came from proprietary and non-proprietary sources, was not necessarily comprehensive and was not guaranteed to be error-free.
No causal price claim follows from the report alone. Cryptocurrency trades continuously across many venues, while the flow window covered the five business days from March 11 through March 15. Without instrument-level subscription records and a defined market-price window, the evidence could not determine how much of bitcoin’s contemporaneous movement was caused by fund demand. What the March 18 publication established was narrower: covered products had recorded two successive weekly inflow records, and the reported demand was overwhelmingly concentrated in bitcoin.
