US spot Bitcoin exchange-traded funds (ETFs) have recorded a sixth consecutive week of net inflows, marking the longest such streak since August 2025. The current run, spanning from the week of April 2 through May 9, has attracted a combined $3.4 billion, according to data from SoSoValue. The development signals sustained institutional interest in Bitcoin exposure through regulated financial products, even as broader market sentiment remains mixed.
ETF inflows show institutional conviction
The six-week streak is the strongest showing for spot Bitcoin ETFs in over nine months. The most sturdy week came in mid-April, when inflows hit $996.38 million for the week ending April 17. The weakest week of the streak was the first, starting April 2, which saw just $22.34 million in net inflows. The most recent week logged $622.75 million, indicating steady capital deployment rather than a sudden spike.

However, the streak ended on a cautious note. The final two days of last week saw outflows of $277.50 million on Thursday and $145.65 million on Friday, reversing strong momentum from earlier in the week when Monday and Tuesday pulled in $532.21 million and $467.35 million respectively. Wednesday’s inflows slowed sharply to $46.33 million before the late-week reversal. This pattern suggests that while the overall trend remains positive, short-term profit-taking or repositioning can still create volatility in flows.
For context, the previous record streak — a seven-week run from June 13 to July 18, 2025 — drew in roughly $7.57 billion, including $2.72 billion in a single week. The current streak, while shorter in duration, demonstrates that institutional appetite for Bitcoin ETFs has not faded entirely despite the broader crypto market’s consolidation phase.

Senator Warren presses Meta on stablecoin strategy
US Senator Elizabeth Warren has sent a letter to Meta Platforms CEO Mark Zuckerberg demanding transparency about the company’s stablecoin initiatives. In the letter, Warren described Meta’s limited disclosures as “deeply troubling,” referencing the company’s failed Libra project — later rebranded as Diem — which faced intense regulatory opposition before being abandoned.
The scrutiny comes after Meta quietly expanded stablecoin payouts using USD Coin (USDC) for select content creators in the Philippines and Colombia in April. Warren’s letter questions whether Meta is pursuing a broader stablecoin strategy without adequate regulatory safeguards or congressional oversight. The senator has long been a vocal critic of cryptocurrency risks, particularly around consumer protection and financial stability.
Meta has not publicly confirmed any plans to launch a proprietary stablecoin, but the expansion of USDC-based payments suggests the company is testing the infrastructure for digital dollar transactions on its platforms. The outcome of this regulatory pressure could influence how large technology companies approach stablecoin integration in the future.
Tether freezes over $500 million USDT in 30 days
Onchain data from BlockSec’s USDT Freeze Tracker reveals that Tether has frozen more than $514 million in USDT across Ethereum and Tron over the past 30 days. As of May 9, the tool shows 370 addresses blacklisted in that period — 328 on Tron and 42 on Ethereum — with approximately $505.9 million frozen on Tron and $8.73 million on Ethereum.
The figures underscore Tether’s growing role in crypto-related enforcement actions. The concentration on Tron suggests that most recent high-value freezing activity is occurring on that network, which has historically been popular for peer-to-peer transfers and remittances in emerging markets.
BlockSec’s analysis of 2025 data found that Tether blacklisted 4,163 unique addresses across both networks, freezing a total of $1.26 billion in USDT. Of that amount, more than half — about $698 million — was later destroyed via the contracts’ “destroyBlackFunds” function. Only 3.6% of those addresses were subsequently removed from the blacklist, indicating that once Tether imposes a freeze, it is rarely reversed.
A separate study covering 2023 to 2025 estimated that Tether immobilized roughly $3.3 billion across 7,268 addresses in those three years, far outpacing rival stablecoin issuer Circle over the same period. The current pace of freezes suggests Tether could exceed its 2025 total in blacklisted USDT well before the end of the year.
What this means for the crypto ecosystem
The simultaneous developments highlight a maturing market where institutional adoption through regulated products coexists with increased enforcement activity. The sustained Bitcoin ETF inflows suggest that traditional finance remains interested in crypto exposure, while Tether’s aggressive freezing actions demonstrate that stablecoin issuers are increasingly cooperating with law enforcement and compliance frameworks.
Senator Warren’s scrutiny of Meta’s stablecoin plans adds a regulatory dimension that could shape how technology companies approach digital payments. For readers, the key takeaway is that the crypto industry is moving toward greater regulatory engagement, both through voluntary compliance by issuers like Tether and through legislative pressure from policymakers.
FAQs
Q1: Why are Bitcoin ETF inflows significant?
They indicate sustained institutional demand for Bitcoin through regulated investment vehicles, which can support price stability and market maturity. Six consecutive weeks of inflows suggest that professional investors are allocating capital to Bitcoin despite market uncertainty.
Q2: Why is Senator Warren questioning Meta about stablecoins?
Warren has a history of scrutinizing cryptocurrency risks. She is concerned that Meta’s stablecoin activities could pose consumer protection and financial stability risks, especially given the company’s failed Libra project. Her letter demands transparency about Meta’s current stablecoin strategy.
Q3: What does Tether freezing USDT mean for users?
Tether freezes addresses that are flagged as high-risk or linked to investigations, often in coordination with law enforcement. For regular users, this demonstrates that stablecoins are not anonymous and can be frozen or seized. It also shows that Tether is actively enforcing compliance measures on its network.
