Spot Bitcoin ETFs saw their worst weekly outflow in four months, signaling a sharp reversal in institutional sentiment after a six-week streak of accumulation.

U.S. spot Bitcoin exchange-traded funds (ETFs) recorded more than $1 billion in net outflows for the week ending May 16, bringing a six-week stretch of consecutive inflows to an abrupt halt. The reversal in fund flows shows a significant shift in institutional positioning, as Bitcoin (BTC) struggles to hold support above $78,000.
"This level has historically acted as a key resistance-turned-support band during bear markets," analysts at CryptoQuant said in a note, pointing to rising profit-taking and weakening U.S. spot demand as signs that momentum may be fading. The firm's on-chain data suggests potential support near $70,000 if a deeper correction develops.
The bulk of the selling pressure was concentrated on May 13, which saw a single-day outflow of $635 million, the largest since late January. Data from Farside shows BlackRock’s iShares Bitcoin Trust (IBIT) and Fidelity’s Wise Origin Bitcoin Fund (FBTC) led the redemptions. The move marks a stark contrast to the seven-week inflow period that preceded it, where funds had consistently pulled in capital, according to data from SoSoValue.
The outflows suggest institutional capital is becoming more selective, rotating out of assets without immediate positive drivers and into those with specific catalysts. While Bitcoin and Ethereum ETFs bled a combined $824 million on May 13, funds linked to XRP and Solana continued to attract capital, shielded from the broader market pressure by asset-specific news.
While Bitcoin ETFs faced heavy redemptions, products offering exposure to XRP and Solana demonstrated surprising resilience, driven by distinct, positive narratives. XRP spot ETFs, for instance, pulled in $18.52 million on May 14, the same day the CLARITY Act, which would provide regulatory certainty for the asset, cleared a key Senate committee. The funds have seen only one day of outflows in over three weeks.
Similarly, Solana-linked funds logged their 11th consecutive day of inflows through May 14, absorbing another $26.57 million. The demand appears tied to the Alpenglow upgrade, which recently went live on a testnet and promises to dramatically increase the network's transaction speed. The sustained buying in XRP and SOL, while BTC and ETH faltered, shows that institutional investors are no longer making a single bet on the crypto space but are actively allocating based on specific, near-term catalysts.
The recent ETF outflows coincide with Bitcoin's failure to break past resistance near the 200-day moving average around $82,400. According to CryptoQuant, the rally from April lows has elevated unrealized gains, prompting a wave of profit-taking. The price of Bitcoin was trading around $78,500 as of 18:00 UTC on May 16, down approximately 4.7 percent over the past seven days.
The key question for investors is whether the recent selling is a short-term correction or the beginning of a more sustained downturn. Without a new, compelling catalyst to drive demand, Bitcoin's price action in the coming weeks will likely be dictated by the flow of funds in and out of its spot ETF products.
