Digital asset investment products experienced their largest weekly net inflows on record last week, totaling $3.13 billion, according to CoinShares.

What Happened: This surge brings year-to-date inflows to an unprecedented $37 billion, driven primarily by Bitcoin ETFs, which alone accounted for $3.12 billion, the report stated.

"This marks the largest single-week inflow we've ever recorded," stated James Butterfill, Head of Research at CoinShares. "Bitcoin's dominance in these inflows underscores the growing institutional confidence in the asset as a long-term investment."

Bitcoin (CRYPTO: BTC) attracted the lion's share of inflows, adding $3 billion to its investment products.

However, the report also noted a $10 million inflow into short-Bitcoin products, reflecting some investor caution as Bitcoin prices hit new highs.

Monthly inflows into short-Bitcoin products reached $58 million, the largest post since August 2022.

Altcoins also saw significant activity.

Solana (CRYPTO: SOL) outpaced Ethereum (CRYPTO: ETH) for the week, pulling in $16 million compared to Ethereum's $2.8 million.

Other notable altcoin inflows included XRP (CRYPTO: XRP) ($15 million), Litecoin (CRYPTO: LTC) ($4.1 million) and Chainlink (CRYPTO: LINK) ($1.3 million).

Despite Solana's weekly performance, Ethereum remains the stronger performer on a year-to-date basis.

The record U.S. inflows of $3.2 billion were partially offset by outflows in Europe, with Germany, Sweden, and Switzerland seeing withdrawals of $40 million, $84 million, and $17 million, respectively.

"Recent price highs appear to have prompted profit-taking in these markets," Butterfill said.

Meanwhile, more optimistic sentiment drove inflows in Australia ($9 million), Canada ($31 million), and Hong Kong ($30 million).

While single-asset products like Bitcoin and Solana saw strong demand, multi-asset investment products faced their second consecutive week of outflows, losing $10.5 million, indicating a preference for concentrated bets on specific digital assets rather than diversified portfolios.

CoinShares highlighted the stark contrast between Bitcoin ETFs and U.S. Gold ETFs, which attracted just $309 million in their debut year.

Bitcoin's YTD inflows far outpace the gold product's early performance, emphasizing the increasing institutional appetite for crypto.
