Crypto Funds Extend Six-Week Inflow Streak as Bitcoin Rally Builds

Global crypto investment products recorded $857.9 million in inflows last week, marking the sixth consecutive week of positive flows. Bitcoin funds led the surge with $706.1 million, while short-bitcoin products saw their largest outflows of the year, signaling a shift in trader sentiment. The rally is bolstered by growing optimism around the CLARITY Act, the long-awaited market-structure bill heading to a Senate Banking Committee markup on May 14. Political tensions over stablecoin yields and banking opposition remain key risks as the vote approaches.

Crypto Funds Extend Six-Week Inflow Streak as Bitcoin Rally Builds

Crypto funds are on a six-week winning streak, with the latest $857.9 million inflow wave driven by Bitcoin and heightened expectations for U.S. crypto regulation. But the path ahead hinges on a high-stakes Senate markup that could reshape the industry.

What to know

  • Global crypto investment products attracted $857.9 million in the week ending May 12, extending a positive streak to six consecutive weeks.
  • Bitcoin-based funds drew $706.1 million of that total, the largest share, as the flagship crypto reached its highest price levels in months.
  • Short-bitcoin products experienced $14.4 million in outflows, the biggest withdrawal of the year, indicating traders are unwinding bearish bets.
  • The previous week’s inflows were $117 million, meaning the latest figure represents a more than sevenfold increase week-over-week.
  • The CLARITY Act, a federal crypto market-structure bill, is set for markup before the Senate Banking Committee on May 14 after months of stalled negotiations.
  • A small group of seven Democratic lawmakers holds pivotal votes, while the American Bankers Association has escalated warnings that the bill could trigger deposit flight into stablecoins.
  • A senior White House official accused major banking trade groups of refusing to engage in earlier talks on stablecoin rewards, one of the final pressure points before the markup.
  • Total assets under management in crypto investment products have climbed to $4.9 billion, according to CoinShares data.

The Rally Gathers Steam

The numbers are unambiguous: institutional and retail investors are piling back into crypto. After weeks of modest but steady inflows, the latest surge—nearly $858 million—represents a sharp acceleration. Bitcoin alone captured over 82% of the total, a sign that confidence in the oldest and largest cryptocurrency is spreading beyond niche traders into mainstream allocators.

What makes this rally different from earlier ones is the simultaneous exodus from short-bitcoin products. The $14.4 million outflow from these vehicles is the largest in 2026, suggesting that even the most skeptical traders are closing their bearish positions. When short funds bleed, it often signals that the market expects further upside—or that the cost of maintaining a short is becoming prohibitive as prices climb.

This momentum doesn’t exist in a vacuum. The six-week streak began in early April, when inflows were modest. But the inflection point came in late April, when the CLARITY Act re-entered the legislative calendar. Crypto funds jumped from $117 million in the week ending April 24 to nearly eight times that amount in the latest period. The correlation between legislative progress and capital flows is hard to ignore.

The CLARITY Act Catalyst

The CLARITY Act (Crypto Law and Regulatory Integrity for Tomorrow Act) is the most ambitious attempt yet to create a federal framework for digital assets. It aims to define which tokens are commodities and which are securities, establish rules for stablecoins, and give the Commodity Futures Trading Commission (CFTC) primary oversight of crypto spot markets. The bill has been in development for over a year, but its passage is far from assured.

On May 14, the Senate Banking Committee will hold a markup—a formal session where lawmakers debate, amend, and vote on the bill. The event has been postponed multiple times, making this week’s scheduled vote a critical juncture. According to a report from CryptoSlate, the markup hinges on seven Democratic senators who have not yet committed their support. Their votes could determine whether the bill advances to the full Senate or stalls indefinitely.

Optimism has grown in recent days. The committee released the full text of the bill ahead of the markup, a procedural move that suggests leadership expects a serious effort to pass it. Crypto industry leaders, speaking to Decrypt, said they are the most confident they have been in months—but acknowledged that the outcome is still uncertain.

Political Drama on Capitol Hill

The path to the markup has been anything but smooth. The American Bankers Association (ABA) has mounted a vocal campaign against a key provision of the CLARITY Act that would allow stablecoin issuers to pay yields to holders. Banks argue that such yields would pull deposits out of traditional institutions, destabilizing the banking system. The ABA amplified those warnings on May 11, just days before the markup, calling on lawmakers to tighten yield limits.

In a surprising escalation, a senior White House official revealed that major banking trade groups had refused to attend meetings with the administration to resolve the stablecoin rewards dispute. The official accused the bankers of walking away from the negotiating table, leaving the White House unable to broker a compromise. This public rebuke has put the banking lobby on the defensive and may shift the political calculus for undecided senators.

The CLARITY Act also faces pressure from within the crypto industry. Some advocates worry that the bill is too accommodating to traditional finance, while others fear that overly strict stablecoin rules could stifle innovation. The markup will likely feature amendments on both sides of the issue, making the final text unpredictable.

What the Inflows Tell Us

The surge in crypto fund inflows is not just a bullish signal—it’s a real-time referendum on the CLARITY Act’s chances. Investment flows are forward-looking. When large sums enter Bitcoin products, they reflect a bet that the regulatory environment will improve, that institutional adoption will accelerate, or both.

Six consecutive weeks of positive inflows break the pattern of short-lived rallies that have characterized crypto markets in recent years. The total of $4.9 billion now sitting in these products is the highest since early 2025. If the CLARITY Act passes the committee and eventually becomes law, that number could grow substantially as pension funds, endowments, and other risk-averse institutions gain the regulatory clarity they have been waiting for.

Conversely, if the markup fails or produces a bill that industry considers hostile, the inflows could reverse quickly. Short-bitcoin outflows have already reversed once this year; they could resume if sentiment turns.

Risks on the Horizon

Despite the rally, several risks loom. First, the Senate Banking Committee vote is not the final step. Even if the CLARITY Act advances, it must pass the full Senate, reconcile with the House version, and survive potential presidential veto threats. Each stage presents opportunities for delay or derailment.

Second, the stablecoin yield debate could fracture the coalition supporting the bill. If the ABA succeeds in inserting restrictive language, crypto advocates might withdraw support. If the industry gets everything it wants, banks could lobby against the final bill, making it harder to secure votes from moderate Democrats.

Third, the broader macroeconomic environment remains uncertain. Bitcoin’s price rally has been fueled in part by expectations of easier monetary policy, but if inflation reaccelerates, those expectations could unwind. Crypto investment products are still a relatively small asset class, and they remain sensitive to shifts in risk appetite.

Finally, the White House involvement adds a layer of complexity. The administration’s willingness to publicly shame banking groups suggests it wants the CLARITY Act to pass, but it also means the White House has political capital at stake. If the bill fails, the fallout could damage the administration’s credibility on crypto, leading to a longer regulatory freeze.

Looking Ahead

The next week will be decisive. The Senate Banking Committee markup on May 14 will determine whether the CLARITY Act moves forward or stalls. For crypto investors, the outcome is as important as any price chart. If the bill passes committee with strong bipartisan support, the six-week inflow streak could extend into a multi-month surge. If it falters, the rally may lose its engine.

Bitcoin’s price action will likely remain correlated with legislative headlines. The $706.1 million flowing into Bitcoin funds last week is a bet on clarity. Whether that bet pays off depends on a handful of lawmakers, a banking lobby, and the White House’s willingness to broker a deal.

For now, the trend is clear: conviction is rising. But in crypto, conviction can turn in an instant. All eyes are on Capitol Hill.
