US spot Bitcoin ETFs recorded $506.5 million in net inflows on Wednesday, marking the strongest single-day intake since early February as Bitcoin climbed back above $68,000.The renewed demand has pushed weekly ETF inflows to $560.4 million, putting funds on track for their first positive week after five consecutive weeks of net outflows totaling $3.8 billion, according to data from SoSoValue.The rebound follows a sharp February sell-off that erased roughly $20 billion in net ETF assets, suggesting institutional positioning may be stabilizing.BlackRock’s IBIT Leads Inflows as Trading Volumes SurgeThe largest inflows were seen in BlackRock’s iShares Bitcoin Trust (IBIT), which attracted $297.4 million in a single session, according to data from Farside.Other notable inflows included:Bitwise Bitcoin ETF (BITB): $39.4 millionFidelity Wise Origin Bitcoin Fund (FBTC): $30.1 millionETF trading activity also rebounded sharply, with total daily volumes surpassing $4.3 billion, the highest level since Feb. 9.The resurgence in flows coincided with Bitcoin reclaiming key technical levels above $68,000, reinforcing the perception of renewed institutional engagement.Market Structure Debate IntensifiesThe rebound in ETF inflows comes amid ongoing debate about Bitcoin price discovery and the role of authorized participants (APs) and major trading firms such as Jane Street.Speculation intensified following a lawsuit tied to the 2022 collapse of Terraform Labs’ TerraUSD stablecoin. Online discussions have questioned whether derivatives exposure and ETF-related mechanics could influence Bitcoin’s price structure.Bitwise adviser Jeff Park addressed the topic on social media, emphasizing that while no authorized participant explicitly suppresses Bitcoin’s price, ETF market structure can impact how price discovery unfolds.He noted that concerns about “paper Bitcoin” — trading exposure without acquiring underlying BTC — reflect broader questions about transparency rather than direct manipulation.ETF Recovery After Prolonged PressureDespite two strong inflow days, broader sentiment remains cautious. Bitcoin has faced persistent selling pressure since October 2025, and ETF assets under management remain well below recent peaks.However, the combination of:Consecutive daily inflowsRebounding ETF trading volumesBitcoin reclaiming $68,000A potential weekly net inflow after five negative weekssuggests that institutional demand may be returning incrementally.If inflows continue and BTC holds above key support levels, ETFs could play a pivotal role in stabilizing market structure following February’s volatility.For now, the ETF market appears to be regaining momentum — but sustained buying will be necessary to confirm a broader trend reversal.
