April Brings Nearly $2B Into Spot Bitcoin ETFs, Pushing 2026 Flows Back Into Positive Territory

April delivered the strongest all-around showing for crypto markets since late last year, with Bitcoin posting an almost 12% monthly gain and spot Bitcoin ETFs drawing in nearly $2 billion. Spot Bitcoin ETF flows also flipped back to positive for 2026. After a record July 2025, when these funds took in more than $6 billion, inflows stayed elevated in September and October at about $3.5 billion each month. Sentiment reversed in November as roughly the same amount was pulled out amid broad crypto weakness. Redemptions continued with over $1 billion in December and another $1.6 billion in January. February’s outflows eased to $206 million, still negative. March ended the four-month run of net withdrawals with $1.32 billion in inflows. April built on that momentum: alongside Bitcoin's rally, spot Bitcoin ETFs attracted just under $2 billion, their best month since October, according to SoSoValue. Combined, March and April flows lifted cumulative 2026 net inflows to nearly $1.5 billion. BlackRock's IBIT remains the clear leader by total net flows, followed by Fidelity's FBTC. Ethereum ETFs also saw a turn in April, ending a five-month stretch of losses that became the worst streak in the history of spot Ethereum ETFs. The funds tracking ETH recorded net outflows of $1.42 billion in November, $616 million in December, $353 million in January, $370 million in February, and $46 million in March. April finally broke the pattern with $356 million of net inflows. Even so, year-to-date flows remain negative, with more than $410 million exiting over the first four months of 2026. BlackRock's ETHA leads the category, with Fidelity's FETH next. Source: SoSoValue
