- Bitcoin ETFs saw $385M inflows on May 27, extending nine days of steady institutional buying momentum.
- Ethereum ETFs gained $38.8M amid signs of ETH/BTC gearing up for a possible breakout above 0.0560 resistance.
- Major funds like Fidelity and ARK are driving continued ETF inflows, while large treasury plays boost market confidence.
Spot Bitcoin ETFs drew $385 million in inflows on May 27, extending a nine-day streak of net institutional buying. Ethereum ETFs followed with $38.8 million in cumulative gains over the same period, signaling coordinated accumulation across both assets.
According to a post by Coin Bureau, consistent capital inflows throughout late May reflected strategic positioning by institutional investors. Activity peaked on May 22 with $877.2 million in Bitcoin ETF inflows, with Invesco, ARK, and Fidelity absorbing significant demand. Despite intermittent profit-taking, especially on May 23, daily flow momentum remained intact due to continued allocations from BlackRock and iShares.
Flows began rising on May 14 as Bitcoin ETFs captured $232.9 million, supported by Bitwise and Invesco. The following day saw a gross increase to $409.7 million, though redemptions from Fidelity, ARK, and Grayscale reduced net gains to $114.9 million. From May 19 to 22, net inflows consistently surpassed $300 million, marking the highest sustained ETF demand since January.
Ethereum Chart Signals Altcoin Rotation Potential
Simultaneously, other market indicators suggest a different trend. ETH/BTC technicals show a potential breakout from a descending channel that has contained the pair since April 2023. According to CW, ETH/BTC tested the upper trendline resistance near 0.0550 for a third time in five months, with price currently consolidating just below that level.
The channel structure remains intact for now, but volume surges between 0.0470 and 0.0560 signal rising participation. While recent candles indicate cooling momentum, traders are watching for a confirmed close above 0.0560 to validate a trend reversal. Key support at 0.0500 remains unbroken, aligning with previous reaction zones.
On May 16, Ethereum ETFs saw modest inflows of $22.2 million, primarily from Fidelity. A sharp uptick followed on May 20 with $64.8 million in flows, with ARK and Fidelity leading the push. After a brief setback on May 21, funds rebounded on May 22 with $110.5 million in new allocations, followed by $58.6 million on May 23. May 27 closed with $38.8 million in net Ethereum ETF flows.
Capital Deployments Align With ETF Momentum
Recent movements in the sector have reshaped priorities. Large-scale treasury plays emerged as Vivek’s Strive raised $750 million for Bitcoin purchases and SharpLink committed $425 million to acquire Ethereum via a PIPE deal. Trump Media disclosed a $2.5 billion Bitcoin allocation, adding further institutional weight behind ongoing flows.
Policy and regulatory voices have begun aligning with this institutional activity. Senator Lummis suggested the U.S. should hold 5% of the global Bitcoin supply, supporting broader integration into national reserve discussions. Technical sentiment is rising across trading desks as ETH/BTC’s setup resembles historic rallies, prompting rotation strategies into altcoins ahead of a potential breakout.
On May 27, Bitcoin ETF net inflows reached $385.4 million after iShares added $36 million, partially offsetting ARK’s $38.3 million outflow and smaller withdrawals from Fidelity and Grayscale. Ethereum ETF flows remained bullish, led by Fidelity’s $32.5 million injection alongside smaller contributions from ARK and Bitwise.
