Bitcoin exchange-traded funds recorded $635.23 million in outflows on May 13, the biggest single-day exodus since January 29. The selloff marks two consecutive days of redemptions, putting a six-week streak of positive weekly inflows in serious jeopardy. So far this week, net outflows total $841.19 million — nearly wiping out the $1.68 billion that poured in during the first six days of May.
Six weeks of gains unravel
The six-week run that began in late March brought roughly $3.4 billion into spot Bitcoin products, the longest positive streak since July 2025. April was the strongest month on record for Bitcoin funds, with $1.97 billion in net inflows, led by BlackRock's iShares Bitcoin Trust. But the tide turned abruptly after May 6. Since then, four of the last five trading sessions have seen outflows, with only a $27.29 million inflow on May 11 breaking the pattern.
Mixed signals from altcoin funds
Ethereum funds didn't escape the downturn, logging three straight days of outflows. Solana ETFs, by contrast, have held up well — not a single outflow day in May, pulling in $90.83 million across eight positive sessions and one flat day. XRP ETFs saw three days of zero flows, while Dogecoin funds managed only three inflow days, each with modest sums. Chainlink products posted four inflow days in May, a quieter but still positive showing.
Hyperliquid ETF keeps its streak
One bright spot: 21Shares' Hyperliquid ETF, which debuted on May 12, has maintained a positive streak through its first two sessions, collecting $2.52 million. It's a small sum compared to the Bitcoin outflows, but notable for a brand-new product in a risk-off week.
The question now is whether this week's outflows persist into next week, or if a snapback in sentiment can salvage the six-week streak. Friday's trading session — the last before the weekly flow tally closes — will be the tell.
