Investors Trade $1B+ Daily in Bitcoin ETFs as Flows Shift to Selective Risk

The week opened with hesitation and closed with conviction. That contrast defined ETF flows between April 27 and May 1, as investors shifted from early caution to renewed, if selective, risk-taking.

Bitcoin spot ETFs ultimately recorded net inflows of $162.8 million, but the path was far from smooth. The first three sessions were marked by consistent outflows, reflecting profit-taking after a prior rally. Momentum turned decisively on Friday, when a sharp $630 million inflow flipped the weekly balance into positive territory.

Underneath the headline figure, flows were uneven. Blackrock’s IBIT led the week with $136.6 million in inflows, reinforcing its role as the anchor product for institutional demand. Ark & 21Shares’ ARKB also posted a solid $50.1 million gain, while Fidelity’s FBTC added $48.5 million.

Elsewhere, activity was more mixed. Morgan Stanley’s MSBT drew $15.3 million, and smaller inflows were seen in Bitwise’s BITB and Grayscale’s BTC product. On the other side of the ledger, Grayscale’s GBTC continued to face pressure, shedding $73.6 million over the week. Outflows were also recorded in Vaneck’s HODL, Franklin’s EZBC, and Invesco’s BTCO.

Trading volumes remained consistently strong throughout the week, often exceeding the billion-dollar mark each day. Even during the outflow sessions, engagement did not drop off, suggesting that investors were reallocating rather than exiting the market entirely.

Ether ETFs painted a more subdued picture. The segment recorded net outflows of $82 million for the week, extending a pattern of cautious positioning. Several sessions saw steady redemptions, driven largely by exits from major products such as Blackrock’s ETHA (-$71.45 million) and Fidelity’s FETH (-$50.26 million).

There were moments of support. Blackrock’s ETHB ($44.50 million) continued to attract inflows on select days, acting as a partial counterweight. Still, these were not enough to offset the broader selling pressure. By week’s end, the tone around ether ETFs remained fragile, with investors appearing more hesitant compared to bitcoin.

In smaller-cap products, flows were muted but telling. XRP ETFs recorded a marginal net outflow of $35,000, effectively flat over the week but indicative of a lack of strong directional conviction. Activity was sporadic, with occasional inflows offset by equally modest redemptions.

Solana ETFs followed a similarly quiet trajectory, posting net outflows of $1.2 million. Several sessions saw no trading activity at all, highlighting the still-developing nature of investor interest in these products.

Taken together, the week reflects a market in transition. Bitcoin continues to command the bulk of institutional attention, with its ability to attract late-week inflows underscoring underlying demand. Ether, by contrast, is navigating a more cautious phase, while XRP and solana remain on the periphery, waiting for stronger catalysts.

The divergence is clear. So is the message: investors are still engaged, but they are choosing their exposure carefully.
