RIOT SHEDS 9,665 BTC IN H1 — MINERS STOP KEEPING THE COINS THEY MINE, ANTHROPIC RENT IS DUE
Riot Platforms sold 4,300 BTC in Q2 2026, drawing its H1 total to 9,665 bitcoin. Treasury now 11,380 BTC as of June 30, down from ~15,680 at quarter start. 5,821 of that remaining stack — over half — is pledged as collateral against existing loans. It isn’t freely available for the company to sell or move without first satisfying lenders. The mining side still runs: 1,587 BTC produced in Q2 at $49,912 average cost. But the coins mined aren’t staying in Riot’s vault. They’re funding a $9.1 billion, 20-year, 191-megawatt Anthropic datacenter lease.
Riot is not alone. Marathon — the largest publicly traded miner — sold ~23,093 BTC for $1.6 billion in H1 at $70,631 average. Publicly listed miners collectively sold 32,000+ BTC in Q1 2026 alone. That single-quarter figure exceeded their combined full-year 2025 sales. Bitdeer Technologies now holds zero Bitcoin reserves. Cleanspark has reorganized its leadership team specifically to accelerate AI initiatives rather than grow the Bitcoin stack.
The Technologist read. This is a protocol-level shift, not a corporate story. For years the miner-treasury model held that miners should be net accumulators — producing coins and holding them, converting operational surplus into balance-sheet Bitcoin. The AI pivot inverts that. Miners are now net sellers of the very asset they secure the network to produce. The block reward keeps flowing. It just doesn’t stay with the operators anymore.
The mechanism, plainly. A 191MW Anthropic lease generates ~$9.1B in projected revenue through 2048. Riot’s AI/HPC expansion has been valued as high as $21B by Starboard. Set against a $730M Bitcoin treasury at current prices, the AI datacenter economics are simply larger than the accumulated Bitcoin. The rational corporate response is to sell the smaller asset to fund the larger buildout. That’s exactly what’s happening across the sector.
What this means for hashrate. Network hashrate has already dropped ~17% from its late-2025 peak, easing from 1 ZH/s to ~850-920 EH/s. CoinShares projects AI and HPC services could account for as much as 70% of listed miners’ revenue by year-end 2026. That doesn’t threaten Bitcoin’s security — difficulty adjusts, and the remaining miners profit more per unit hashrate. But it does mean the miner class as a durable Bitcoin-treasury cohort is dissolving in real time.
The operator takeaway. Miner-treasury companies are no longer BTC-accumulation vehicles. They’re now AI infrastructure companies with a mining side-business. If you were long a public miner because you thought it was BTC-per-share compounding, that thesis is broken. The Bitcoin-per-share number is going down at Riot, at Marathon, at Cleanspark, at Bitdeer. Whether the AI infrastructure story replaces the BTC-treasury story with something better is a separate valuation question.

The protocol keeps producing blocks.
The miners stopped keeping them.
The cap is still twenty-one million.
