Bitcoin ETFs Post Six-Week Inflow Streak; Tether Freezes $514M

US spot Bitcoin exchange-traded funds recorded a sixth consecutive week of net inflows from the week of April 2 through the most recent Friday, totaling $3.4 billion, data from SoSoValue shows. The period included a peak weekly inflow of $996.38 million in the week of April 17 and a low of $22.34 million in the week of April 2. The most recent weekly total was $622.75 million. SoSoValue identified the run as the longest streak of consecutive weekly inflows since August 2025.

Weekly flows within the most recent week were uneven. Monday and Tuesday brought inflows of $532.21 million and $467.35 million, respectively. Wednesday slowed to $46.33 million, and late-week activity produced outflows of $277.50 million on Thursday and $145.65 million on Friday. SoSoValue also noted an earlier seven-week inflow run from June 13 to July 18, 2025 that drew roughly $7.57 billion, including $2.72 billion in the week of July 11 and $2.39 billion the following week.

Onchain enforcement by stablecoin issuer Tether increased over the past 30 days. BlockSec’s USDT Freeze Tracker shows about $514.6 million of USDT frozen across 370 addresses during that period, with 328 addresses on the Tron network and 42 on Ethereum. Approximately $505.9 million was immobilized on Tron and about $8.73 million on Ethereum. The freezes use blacklist functions in Tether contracts to block funds identified as high-risk or connected to investigations.

BlockSec’s analysis of 2025 onchain data found that Tether blacklisted 4,163 unique addresses across Ethereum and Tron, freezing about $1.26 billion in USDT. Of that amount, roughly $698 million was later removed from circulation using the contracts’ destroyBlackFunds function. Only about 3.6% of blacklisted addresses were subsequently removed from blacklists in 2025. A separate review covering 2023–2025 estimated that Tether immobilized roughly $3.3 billion across 7,268 addresses over those three years.

In a letter to Meta Platforms’ CEO Mark Zuckerberg, Senator Elizabeth Warren described the company’s disclosures on stablecoin plans as “deeply troubling” and wrote that “it is critical that Meta be transparent with Congress and the public regarding its stablecoin-related plans.” The letter followed Meta’s expansion in April of USDC payouts to select creators in the Philippines and Colombia.
