U.S. spot Bitcoin ETFs pulled in $517M in net inflows on Aug 19, with BlackRock's IBIT accounting for $285M — over half the total. Spot Ether ETFs added $189M the same day, led by BlackRock's ETHA at $122M. Combined crypto ETF inflows reached $𝟳𝟬𝟲𝗠 in a single session, with BlackRock dominating both sides of the flow. 𝗛𝘂𝗽𝘇𝘆 𝘁𝗮𝗸𝗲: BlackRock leading both BTC and ETH on the same day signals 𝗯𝗿𝗼𝗮𝗱-𝗯𝗮𝘀𝗲𝗱 𝗶𝗻𝘀𝘁𝗶𝘁𝘂𝘁𝗶𝗼𝗻𝗮𝗹 𝗱𝗲𝗺𝗮𝗻𝗱 rather than a single-asset rotation. $517M clears the $500M single-day threshold for meaningful flow, and the parallel $189M ETH push lifts combined volume past $700M. Sustained inflow at this pace builds structural buy pressure on both assets.
