US Spot Bitcoin ETFs See Strong Rebound with $506.5 Million Inflows, Marking Largest Daily Gain Since February 2nd

US spot Bitcoin exchange-traded funds (ETFs) experienced a significant rebound on Wednesday, with Bitcoin (BTC) reclaiming the $68,000 mark. This surge was accompanied by substantial inflows totaling $506.5 million, the largest daily inflow recorded since February 2nd. This marks a promising turn for Bitcoin ETFs, which have been grappling with five consecutive weeks of net outflows, amounting to a cumulative $3.8 billion. According to data from SoSoValue, weekly inflows have now reached $560.4 million, signaling a potential shift in investor sentiment.

The recent gains represent two consecutive days of positive inflows, offering a glimmer of optimism following a significant sell-off in February that saw net assets diminish by $20 billion. This renewed interest in Bitcoin ETFs is evident in the trading volumes, which have rebounded to over $4.3 billion, the highest level observed since February 9th.

Leading the charge in Wednesday’s inflows was BlackRock’s iShares Bitcoin Trust ETF (IBIT), which attracted a substantial $297.4 million, according to Farside data. Following IBIT, the Bitwise Bitcoin ETF (BITB) secured $39.4 million in inflows, and the Fidelity Wise Origin Bitcoin Fund (FBTC) garnered $30.1 million. These figures highlight a broad-based recovery in investor participation across major Bitcoin ETF offerings.

The resurgence in Bitcoin ETF trading comes amidst ongoing discussions and scrutiny surrounding market structure and its impact on Bitcoin’s price discovery, particularly concerning the role of large market-making firms and authorized participants (APs). Recent rumors circulating on X, amplified by a lawsuit filed by Terraform Labs administrator Todd Snyder, have implicated Jane Street in allegedly influencing BTC prices through derivatives exposure and market manipulation.

Jeff Park, an advisor at Bitwise, addressed these concerns in an X post, acknowledging the complexity of the issue. He stated, "The answer is trickier than the question… But it’s also more structurally unsettling than the conspiracy theory itself – and once you understand the actual mechanics, you won’t be able to unsee them." Park clarified that while no authorized participant explicitly suppresses Bitcoin’s price, the structure of APs can potentially hinder the integrity of the price discovery mechanism. He emphasized, "Those are not the same thing – but the second is arguably more consequential than the first."

Some analysts have pointed to persistent selling pressure on Bitcoin since October 2025, suggesting that the impact of individual players might be overstated. Nonetheless, concerns about "paper Bitcoin" – where firms trade Bitcoin-related instruments without holding the underlying cryptocurrency – have been a recurring theme since early February. The Kendall Report previously highlighted ETFs as a contributing factor to this phenomenon.

The debate over "paper Bitcoin" intensified following a notable incident at South Korea’s Bithumb exchange. The exchange mistakenly distributed 620,000 BTC that it did not possess, raising further questions about transparency and market integrity within the broader cryptocurrency ecosystem. This event underscores the ongoing challenges in ensuring robust and verifiable market practices, particularly as the adoption of crypto-related financial products like ETFs continues to grow.

The current inflows into US spot Bitcoin ETFs suggest a renewed investor confidence, potentially driven by Bitcoin’s price recovery and a broader acceptance of these regulated investment vehicles. However, the underlying concerns about market structure and the implications of "paper Bitcoin" remain significant topics of discussion within the industry, influencing how investors perceive the long-term stability and fairness of Bitcoin’s price discovery. The coming weeks will be crucial in determining whether this recent inflow trend represents a sustained reversal of previous outflows or a temporary market fluctuation.
