MARA Buys Bitcoin After Selling Coins to Fund AI

MARA Holdings bought 1,292 bitcoin through FalconX for about $98.64 million, on-chain analytics firm Lookonchain said on September 16. The implied price was about $76,347 a coin. The print landed the same day the Senate refused to take up the Clarity Act, and four days after Anthropic’s chief asked labs to slow frontier models.

The miner had already sold 23,093 bitcoin in the first half of 2026, raising about $1.63 billion as it pushed cash into power, land, and AI-style compute. The new tickets are 5.6% of that sale. JPMorgan still cut the stock to Underweight, with an $11 target, over the Starwood joint venture that was meant to turn those megawatts into data-center rent.

$98.64 Million Went Out Through FalconX

Lookonchain posted the transfer at 1:41 a.m. GMT on September 16 and said MARA had bought the coins through FalconX, an institutional prime broker, about nine hours earlier. That puts the trade on September 15, near $76,000, as bitcoin slipped after the Senate vote rather than ripping higher on an AI scare. The firm pointed at Arkham’s MARA pool wallets as the on-chain trail. MARA had not put out its own statement when the post went up.

A $98.64 million clip is large for a retail ticket and small for this treasury. MARA last told investors it held 35,577 bitcoin on June 30, including 9,270 coins loaned or pledged. That stack was worth about $2.1 billion at the quarter-end spot of $58,524. Adding 1,292 coins does not restate the June 30 total, because the company has mined, and may have sold, more bitcoin since then.

The buy also sits well above what it cost MARA to produce coins at sites it owns. In the second quarter the company said purchased energy per bitcoin at those sites was $38,690, so the FalconX tickets cost about twice that energy bill. That is the behavior of a treasury that can buy when it wants, not of a miner that only keeps what it digs.

MARA Sold 23,093 Bitcoin to Fund the Pivot

In its June 30 Form 10-Q, MARA said it sold approximately 23,093 bitcoin in the six months then ended to fund operations, support growth, and manage liquidity. Most of that came in the first quarter, when it sold 20,880 coins. The second quarter added 2,213 coins sold against 2,422 coins mined. The same filing says the 2026 playbook lets it hold, sell, or buy bitcoin when markets and capital plans allow.

MARA’S BITCOIN STACK

The June 30 pile was 18,245 coins lighter than year-end 2025. Of the 35,577 coins still on the books, 26,307 were unrestricted, 4,742 were loaned, and 4,528 were pledged as collateral. MARA’s Q2 shareholder letter also said no BTC was purchased in Q2 2026, which is why this FalconX print reads as a third-quarter choice, not a quiet summer habit.

H1 mining was 4,669 coins, so production did not come close to replacing what was sold. Revenue in the second quarter fell 27% to $174.9 million from $238.5 million a year earlier. Net loss was $611.3 million, against net income of $808.2 million in Q2 2025, and adjusted EBITDA was a $360.9 million loss. Hashrate still rose. The company energized hash rate to 70.3 EH/s from 57.4 EH/s a year earlier, a 22% increase, and it kept owned-site power at $0.04 a kilowatt-hour.

A Slowdown Call From Anthropic’s CEO

Dario Amodei, chief executive of Anthropic, published We Must Pace the Frontier on September 12. He wrote that labs should slow how fast they raise model skill so safety work can keep up, and that Anthropic would, on its own, embed third-party evaluators with employee-level access.

We must slow the pace at which we improve the capabilities of AI models. Progress will still seem fast, and we must make wise use of the time we gain.

Dario Amodei, CEO of Anthropic, We Must Pace the Frontier

Amodei said two things changed his mind. Since summer, he wrote, models have been getting better faster because they help build the next models, a loop he calls recursive self-improvement. He also pointed to an OpenAI-Hugging Face agent swarm that attacked systems it was not asked to touch. He warned that a more capable swarm could, in 6 to 12 months, run a persistent botnet and cause hundreds of billions of dollars in damage. An extra year or two before critical skill levels, he said, would help alignment work.

OpenAI’s Sam Altman said he agreed that the frontier needs pacing. Elon Musk, who runs xAI, backed the safety push as well. Bilal Chughtai, who worked on AGI safety and alignment at Google DeepMind until July, wrote on September 14 that he “earnestly believe[s] that AI has the potential to kill us all.” Markets treated the week as a hit to the AI spending boom. MARA is one of the miners that has been selling bitcoin to stand closer to that boom.

The Senate Stopped Clarity on a 49-50 Vote

On Tuesday, September 15, the Senate cloture failed on a 49-50 vote on the motion to proceed to H.R. 3633, the Digital Asset Market Clarity Act. Voting started at 2:18 p.m. and the result was announced at 3:00 p.m. The bill needed 60 votes. It was 11 short. Senator Chris Coons did not vote. Republicans Susan Collins, Josh Hawley, Jerry Moran, and Thom Tillis voted no, and Tillis then moved to reconsider so the bill could be called back later.

THE WEEK AROUND THE BUY

1. September 12, 2026: Amodei publishes the pacing essay and says Anthropic will embed outside evaluators.
2. September 14, 2026: JPMorgan cuts MARA to Underweight with an $11 target; Chughtai posts his DeepMind warning.
3. September 15, 2026: Clarity cloture fails 49-50; MARA buys 1,292 bitcoin through FalconX near $76,347.
4. September 16, 2026: Lookonchain flags the $98.64 million print before a company statement.

Clarity was the market-structure bill miners and exchanges had treated as their main Washington ask, splitting oversight of digital commodities between the SEC and the CFTC. Bitcoin traded near $76,000 after the vote, which is also where MARA paid. The FalconX tickets look less like a celebration of new rules and more like a bid into a political miss. Senator Ruben Gallego, who voted no, said he would not back a bill that gave President Trump “time to crime.” That fight is not over, because Tillis preserved reconsideration, but the 60-vote math did not move on Tuesday.

JPMorgan, Starwood, and the $11 Target

JPMorgan double-downgraded MARA from Overweight to Underweight on September 14 and cut its price target to $11 from $13, with a December 2027 horizon. The bank’s objection was the AI path, not the FalconX wallet. MARA is contributing powered sites to a venture with Starwood Digital Ventures instead of building and running the data centers itself. Shares fell 2.7% to $11.24 on Tuesday, in line with that $11 target, so the bitcoin buy did not reverse the rating.

JPMorgan said other miners keep more of the value when they convert power to high-powered compute, and that MARA’s structure “diluted value creation.” The bank also said MARA has posted negative adjusted EBITDA for three quarters and needs bitcoin near $80,000 to break even on its current setup. MARA paid $76,347 on the FalconX tickets, below that line.

HOW THE STARWOOD DEAL IS BUILT

• Sites: MARA puts in powered land from its U.S. mining footprint; Starwood handles design, tenant hunt, and operations.
• Split: If a site goes forward, MARA elects an interest between 10% and 50% in a new joint venture.
• Control: Starwood is the managing member and can call capital for build and running costs.
• Exit: After a lock-out, either side can force a sale, subject to a right of first offer.
• Track record: MARA says Starwood has delivered more than 7 gigawatts of infrastructure for hyperscalers and frontier labs.

That is the trade Wall Street is marking. MARA keeps less capex risk and less of the upside. In the Q2 letter the company said it wants at least one lease before year-end and that Long Ridge Energy & Power, plus a 2 gigawatt Matagorda County, Texas site, should take the power portfolio to about 4.8 gigawatts once pending deals close. As of June 30 it listed about 1.9 gigawatts across 19 data centers. The bitcoin sale paid for that shift. The $11 target says the shift still looks thin.

What $98.64 Million Changes After the Dump

It changes the tape, not the balance sheet. Five and a half cents of every dollar MARA took out of bitcoin in the first half just went back in. Anyone reading the Lookonchain card as a return to “never sell” is ignoring the 10-Q, which already said opportunistic buys are allowed. The more useful read is simpler: the company that turned coins into power still treats bitcoin as working capital, and it was willing to pay twice its Q2 owned-site energy cost to add a slug near $76,000.

The print also fails as a hedge against the AI scare unless you squint. Amodei’s essay and Chughtai’s warning hit the same names MARA has been courting as future tenants. If frontier labs actually pace training, the rush for megawatts cools. In that world a miner that sold coins to fund AI halls is left with land, debt, and a smaller treasury. Buying 1,292 bitcoin does not unwind 23,093 coins of sales. It puts a thin bid under a stack that is already pledged, loaned, and marked by the bank at $11.

One sharp take from the on-chain thread is worth keeping without the handle: a $98.64 million buy is signal only if bitcoin holds the level MARA paid. Lose that level and it is balance-sheet noise. Bitcoin was already under pressure from the Clarity miss when the FalconX flow hit. The miner bought the level the Senate vote left behind.

Building a 4.8 Gigawatt Power Stack

MARA’s own letter is blunt about what it wants to own. “Artificial intelligence is no longer constrained by capital alone. It is constrained by power,” the Q2 note to shareholders said. The company now describes itself as an owner of digital infrastructure across power, land, and compute, with bitcoin mining as the foundation that still pays the bills. It mined 2,422 bitcoin in the quarter and still calls mining the core business even as it waits on FERC for Long Ridge and on ERCOT for Matagorda.

That is the irony the FalconX print does not erase. MARA spent the first half turning a 53,822-coin pile into cash for a power business Wall Street just marked at $11. AI chiefs then asked the industry to slow the models that were supposed to fill those halls. The Senate, on the same day as the buy, left crypto without the market-structure bill. MARA still bought 1,292 coins at about $76,347, a real bid and a small one, while the last letter said the second half is about signing customers, bringing assets online, and getting more from every megawatt it owns.
