Institutional capital is flowing back. US spot Bitcoin ETFs registered net inflows of $189.3 million at the close of trading on Tuesday, August 18, 2026. This figure completes a two-day consecutive streak following Monday’s trading session, resulting in a total inflow of $487 million. This two-day haul contributes more than half of the total capital that has flowed into these products throughout August.
With this latest addition, cumulative net inflows for Bitcoin ETFs during August have neared $951 million, climbing up and almost breaking the $1 billion mark. This trend represents a pivot for the market. Previously, Bitcoin ETF instruments recorded consecutive outflows over three trading sessions between August 12 and 14, a pullback period that drained $250 million.
Concentrated in BlackRock’s Hands
Of the funds that flowed in on Tuesday, the majority portion was dominated by a handful of issuers. BlackRock iShares Bitcoin Trust led the inflows, posting $143.6 million alone in a single day. Following in second place, the Fidelity Wise Origin Bitcoin Fund recorded an additional $23.9 million to strengthen its reserves.
This early-week buying rebound has expanded the size of exchange-traded products in the United States. As of the August 18 report, the cumulative net inflows for all US Bitcoin ETFs has accumulated to $52.28 billion. This value brings the total assets under management (AUM) for all spot Bitcoin products to $79.3 billion, indicating how much Bitcoin supply is now held in the vaults of traditional service providers.
Altcoin Instruments Swept Along
Investor interest was not confined to Bitcoin. Ethereum-based investment products, Ether ETFs, also attracted $71.5 million in fresh funds on the same day. This addition lifted Ether ETF inflows to reach $345 million so far this month. This upward trajectory also extended to other crypto instruments, with SOL ETFs recording inflows of $1.58 million and XRP ETFs attracting $5.81 million in capital during the same trading session.
In the open spot market, prices of major crypto assets were in the mid-range when this data was compiled. Bitcoin traded at $64,234, while Ether held at $1,914, according to CoinGecko data. The shift from a $250 million asset dumping trend last week to a $487 million accumulation phase in the first two days of this week highlights the agility of fund managers in rotating their portfolios.
