Spot Ethereum ETFs added $221 million the same day, also on a four-day run, indicating broad institutional demand across crypto and fueling a market-wide rally and short liquidations, though momentum could invite profit-taking.

In Brief

• Spot Bitcoin ETFs booked $606 million in inflows on August 20, a 4-day streak.

Spot Bitcoin (BTC) exchange-traded funds (ETFs) recorded $606.29 million in net inflows on August 20, marking a fourth consecutive day of inflows. The total is the largest single-day haul the funds have seen since May 1.

Spot Ethereum (ETH) ETFs added $221 million the same day, also extending a four-day inflow streak. The dual demand landed as bitcoin traded at $75,524, continuing a market-wide rally that has run through the week.

Bitcoin ETFs Extend a Four-Day Run

Thursday’s inflow followed $517.19 million on August 19, $189.30 million on August 18, and $297.56 million on August 17. Combined, the four-day run has pushed cumulative net inflows for the category to $53.40 billion.

The last time Bitcoin ETFs booked a bigger single day was May 1. That day, the funds pulled in $629.73 million, and total net assets crossed $100 billion for the <a href="https://xpertsstudio.com/bitcoin-breaches-75k-to-challenge-300-ema-first-time-since-january-21-08-2026/" title="Bitcoin Breaches $75K to Challenge 300-EMA First Time Since January (21.08.2026)”>first time.

BlackRock’s IBIT led the day’s inflows with $502.99 million, more than 80% of the day’s total. The broader crypto market rally that has lifted Bitcoin this week has coincided with a wave of short liquidations squeezing bearish positions across the market.

Ethereum Demand Builds Alongside Bitcoin

Ethereum ETFs have moved in step with their Bitcoin counterparts. The category booked $189.15 million on August 19, its largest single-day inflow in 10 months, before adding a further $221 million on August 20.

The simultaneous four-day streaks in both categories suggest institutions are building positions across both assets rather than rotating between them. Total value traded across Bitcoin ETFs reached $5.41 billion on August 20, and total net assets stood at $90.16 billion.

Whether the pace holds into next week may depend on the rally itself. Four straight days of buying could give way to profit-taking if momentum stalls.
