Market signal

A failed Senate vote on crypto's market-structure bill knocks bitcoin off a brief test of $79,000. Bitcoin opened Tuesday at $78,181 (+1.8% on Monday's open), slipped to $76,932 in early US trading, then rallied to touch the high-$78,000s/near-$79,200 intraday as risk sentiment firmed — before the Senate's 2:15pm ET cloture vote on the CLARITY Act failed, sending bitcoin back down to roughly $75,850 (-4.2% on a trailing 24-hour basis). Ether fell in tandem, off about 4.6% to the mid-$2,400s; XRP was down 3.4% to $1.39 and Solana off 3.9%, with Tuesday and Wednesday's Fed meeting (a 25bp hike is priced at roughly 85-90% odds) adding to the pressure into Wednesday's decision.

Markets & flows — ETFs, stablecoins & on-chain

Bitcoin ETFs snap their four-day outflow streak with a $159.9m net inflow. US spot bitcoin ETFs took in $159.9m net on Monday, September 14, per SoSoValue data, ending the run of roughly $463m in outflows that closed out last week; BlackRock's IBIT led with $134.3m in, Morgan Stanley's MSBT added $9.7m and Franklin's EZBC $4.6m, while Fidelity's FBTC (-$53.3m) and ARK's ARKB (-$42m) kept redeeming.

USDC crosses $100 trillion in lifetime on-chain transaction volume. Circle's stablecoin passed the milestone this week, up from $90tn in early July, as USDC's on-chain settlement volume keeps compounding even as reserve interest — not transaction fees — still supplies roughly 95% of Circle's revenue.

The industry — exchanges, miners & infrastructure

CoinShares: bitcoin's price recovery won't pull AI-focused miners back to hashing. With bitcoin back near $77,000, hash price has climbed to about $38 per PH/s/day, pushing most public miners back above cash breakeven — but CoinShares estimates AI hosting still nets miners roughly $1.5m per megawatt against about $500,000 per megawatt from bitcoin mining, a gap wide enough that Keel (formerly Bitfarms) has already exited mining entirely and IREN and TeraWulf continue winding theirs down regardless of coin price.

Policy & regulation

The CLARITY Act dies for 2026 as the Senate's cloture vote falls short, 49-50. Tuesday's procedural vote on the Digital Asset Market Clarity Act needed 60 votes to open debate and got 49; Republicans Susan Collins, Josh Hawley and Jerry Moran crossed to vote no, while Democrats who had spent months negotiating the bill — including Mark Warner, Kirsten Gillibrand, Cory Booker, Catherine Cortez Masto and Angela Alsobrooks — ultimately voted against it too, citing unresolved ethics language around President Trump's personal crypto holdings. Warner said "the failure to address this fundamental conflict of interest made it impossible for me to support moving forward"; lead sponsor Cynthia Lummis called it "now or never" beforehand and said afterward "I think we're done. It's over." With the House out of session for the rest of the year and Congress heading into a midterm split, comprehensive US crypto market-structure legislation is now effectively dead until 2027 at the earliest.

The Chatter

Alex Thorn, Galaxy Digital Head of Research (X, Sep 14): flagged that Monday's "final" CLARITY Act text quietly dropped developers' explicit criminal-law shield under 18 U.S.C. §1960 even as it made the officials'-crypto-issuance ban permanent and broader — leaving intact the same legal theory used to prosecute Tornado Cash's Roman Storm, in his reading, while Galaxy still put the bill's 2026 odds at only 25% ahead of Tuesday's vote.

Matt Cole, Strive CEO (X, Sep 15): called Tuesday's cloture failure "bad for the United States and bad for crypto" broadly, as the industry loses a shot at regulatory certainty this cycle — but argued the same outcome is "good for Bitcoin" specifically, his view being that continued Washington gridlock favors bitcoin's scarcity-and-neutrality case over the rule-dependent parts of the industry.
