U.S. spot Bitcoin exchange-traded funds (ETFs) returned to positive territory on October 15, 2026, recording modest net inflows after the previous session's withdrawals. Spot ETFs hold the underlying asset directly, giving investors cryptocurrency exposure through standard brokerage accounts, and their daily net flow figures are widely tracked as a gauge of fund-level demand. According to the reported ETF flow data for the session, spot Bitcoin ETFs attracted $5.06 million in net inflows during the trading day. The result stood in sharp contrast to the Ethereum market, where U.S. spot Ethereum ETFs saw $60.22 million in net outflows, including $44.39 million in withdrawals from BlackRock's ETHA.

Bitcoin ETFs Record $5.06 Million in Net Inflows

BlackRock's iShares Bitcoin Trust (IBIT) led individual Bitcoin funds with $16.79 million in net inflows. Although IBIT attracted more capital than the overall category's net total, withdrawals from other Bitcoin ETFs offset part of those gains, leaving the group's combined figure only marginally positive.

The positive result marks a shift from October 14, when Bitcoin ETFs recorded $261 million in net outflows. However, the relatively small daily inflow suggests that investor demand remained mixed rather than showing a broad recovery across all funds. The latest figures indicate that some investors continued adding Bitcoin exposure despite recent market uncertainty, even as overall participation stayed uneven.

Ethereum ETFs Record $60.22 Million in Outflows

While Bitcoin ETFs returned to positive territory, Ethereum investment products continued experiencing withdrawals. On October 15, U.S. spot Ethereum ETFs recorded $60.22 million in net outflows.

BlackRock's iShares Ethereum Trust ETF (ETHA) accounted for $44.39 million in net withdrawals. That represented approximately 74% of the category's total net outflow for the day. The figures highlight a clear difference between investor activity in Bitcoin and Ethereum ETFs. Both ETHA and IBIT are issued by BlackRock, the world's largest asset manager, meaning a single issuer recorded net creations in its Bitcoin fund and net redemptions in its Ethereum fund during the same session.

Individual fund figures are included within their respective category totals. Despite Bitcoin's positive result, the two ETF categories experienced approximately $55.16 million in combined net outflows.

What Bitcoin ETF Inflows Mean for Crypto Markets

The latest Bitcoin ETF inflows offer a mixed picture of institutional and traditional market demand for cryptocurrency exposure. Bitcoin funds managed to attract a small amount of net capital, while Ethereum ETFs continued to lose assets through net redemptions. This divergence may reflect different investor preferences, portfolio adjustments or short-term market conditions. However, one trading session is not enough to establish a lasting shift in demand.

ETF flows measure net fund creations and redemptions, not the total amount of cryptocurrency bought or sold across the entire market. They also do not directly determine Bitcoin or Ethereum prices. Investors will likely monitor whether Bitcoin ETFs can maintain positive flows over several sessions and whether Ethereum withdrawals begin to slow.

For now, Bitcoin's $5.06 million inflow offers a modest positive signal, but Ethereum's $60.22 million outflow keeps the overall ETF picture negative.
