Senate Sets Sept. 15 Cloture Vote on Crypto Market Structure Bill

U.S. lawmakers set a key procedural vote for the Senate’s flagship crypto market structure proposal, while a flurry of on-chain signals—from large Bitcoin (BTC) exchange deposits to a low-support Bitcoin soft-fork split—added fresh focus on liquidity movements and operational risk across the sector.

According to The Block, Senate Majority Leader John Thune filed a cloture motion that schedules a vote to end debate on the ‘Clarity’ crypto market structure bill for Sept. 15, 2026. The move is significant because a successful cloture vote would advance the legislation toward full Senate consideration, tightening the timeline for Washington’s most consequential attempt to clarify oversight boundaries for digital asset markets.

Cloture typically requires at least 60 votes, meaning Republicans—who hold 53 seats—would need Democratic support to clear the procedural hurdle. The vote sets up a high-stakes test of bipartisan appetite for a comprehensive framework covering trading venues, token classification, and supervisory coordination, at a time when U.S. regulatory uncertainty remains a central theme for institutional allocators.

On the market side, blockchain trackers flagged notable BTC flows into Binance. Wu Blockchain reported that an address believed to be tied to mining activity deposited 6,400 BTC over the past 20 days, including 2,802 BTC in the two days leading up to Aug. 9 UTC—worth roughly $182 million. While exchange deposits do not automatically translate into imminent selling, miners and large holders are closely watched because their treasury decisions can influence near-term ‘liquidity’ conditions, especially during periods of macro sensitivity.

Bitcoin’s technical governance debate also resurfaced. The Block reported that nodes supporting BIP-110 split onto a separate chain at block height 961,632. The forked chain was running 18 blocks behind the main network, and support in the prior signaling cycle was only 2.53%, indicating limited momentum. BIP-110 is a proposed soft fork that would temporarily restrict the recording of non-payment-related data on the Bitcoin blockchain, a topic that has periodically divided the ecosystem over the network’s intended use and fee-market dynamics.

Hardware wallet maker Ledger urged users not to accept coins from the BIP-110 fork. Odaily said the BIP-110 chain lacks built-in replay protection, meaning transactions signed on the fork could be replayed on the Bitcoin main chain—potentially putting users’ BTC at risk. The warning underscores how chain splits, even those with marginal support, can create ‘operational risk’ for holders if wallet software and infrastructure do not clearly isolate chains.

In Asia, Hong Kong’s Securities and Futures Commission (SFC) added Polar Tensor to its list of suspicious virtual asset trading platforms, according to TechFlow. The SFC publishes the list as a public warning to investors, though the platform’s operator and the specific rationale for inclusion were not immediately confirmed in the report. The update reflects the region’s continued push to distinguish licensed venues from entities operating in gray areas as retail interest persists.

Meanwhile, payments data suggested a growing concentration of crypto card settlement activity on a few networks. Andreessen Horowitz cited PYMNTS data showing that in July, 67% of crypto card payments were settled across Optimism (OP), Solana (SOL), and Base, with shares of 29%, 19%, and 19%, respectively, according to Wushi. The report noted that Gnosis, which was a major settlement network in early 2024, has fallen to around 2%, a shift that highlights how rapidly ‘payment rails’ can consolidate around cheaper fees, faster confirmation times, and stronger integrations with issuers and processors.

Derivatives positioning on Solana also drew attention. Odaily reported a wallet accumulating a 500,000 SOL long position via time-weighted average price (TWAP) execution, with 186,000 SOL already filled. TWAP is commonly used to reduce market impact by splitting large orders into smaller trades over time, often interpreted as a positioning tactic by sophisticated traders seeking discretion and better average fills.

Separately, Onchain Lens and PANews reported that a hacker linked to an attack targeting an early Solana investor moved 2,290 Ethereum (ETH)—about $4.39 million—into mixer Tornado Cash. The transfer came roughly a month after a reported $14.2 million exploit, highlighting the persistent challenge of tracking stolen funds even as compliance scrutiny around mixing services remains elevated globally.

Macro commentary intersected with market narratives as well. Jin10 reported that Rick Rieder, BlackRock’s global fixed income chief investment officer, framed weak U.S. nonfarm payrolls as evidence of an AI-driven productivity shift, arguing companies are learning to increase output without expanding headcount. For crypto markets, such interpretations can matter because expectations for growth, inflation, and rate policy continue to shape risk appetite and cross-asset positioning.

Finally, Odaily reported that a phishing campaign targeting Ledger hardware wallet users has resulted in more than $3 million stolen, with indications that a single operator may be behind multiple related thefts. The incident serves as a reminder that, even as regulators debate market structure and networks evolve, end-user security and social engineering remain among the most immediate threats to retail and professional crypto holders.

As Sept. 15 approaches, the Senate’s procedural vote on the ‘Clarity’ bill will be watched as a proxy for whether U.S. crypto policy can move beyond enforcement-driven uncertainty. At the same time, on-chain flows, fork-related safety warnings, and security breaches underscore that day-to-day market risk still hinges on liquidity behavior and operational resilience across the ecosystem.
