Anthropic Signs $9.1B, 20-Year Compute Lease With Bitcoin Miner Riot Platforms

Anthropic has agreed to lease 191 MW of capacity at Riot Platforms’ Rockdale, Texas campus for 20 years in a deal worth $9.1 billion. The lease runs through June 2048, and two five-year extension options could push the total value to $16.1 billion. Capacity comes online in stages — 96 MW by December 2027 and the full 191 MW by June 2028 — and Anthropic becomes the campus’s second tenant after AMD, which signed in January. The agreement underscores how bitcoin miners are pivoting toward AI infrastructure; Riot’s stock jumped about 20% after the announcement.

‘Encrypted Reasoning’ Cracked — A Shared Flaw Across Anthropic, OpenAI and Google

A new preprint, “Stealing Reasoning Traces from Proprietary LLM APIs,” argues that the encrypted reasoning (chain-of-thought) blocks the three providers return to clients instead of raw reasoning are effectively secured with a single global key per provider, making them replayable across sessions, accounts and models. Inject a stronger model’s encrypted trace into a weaker sibling from the same provider, the authors say, and the weaker model prints that reasoning verbatim — no jailbreak required. Running it at scale, the researchers recovered 315,320 blocks from public repositories and extracted 367 pieces of personally identifiable information and 182 credentials. OpenAI called the report unreproducible, while Anthropic said it saw no security implications but might update its developer documentation.

AgiBot Overtakes Unitree as the World’s Top Humanoid-Robot Vendor in H1 2026

According to Smart Analytics Global (SAG), Shanghai-based AgiBot shipped roughly 8,400 humanoid robots in the first half of 2026 to take a 44% share and the global No. 1 spot, overtaking Hangzhou’s Unitree (about 5,900 units, 31%) for the first time. AgiBot’s shipments surged 562% year over year and Unitree’s rose 170%, with the two vendors together accounting for about 75% of global shipments. Chinese makers captured roughly 97% of all humanoid shipments, and AgiBot is currently pursuing an IPO — putting the leadership shift squarely alongside its public-listing push.

Today’s Takeaway

On the infrastructure front, Anthropic extended the race for dedicated compute with a $9.1B long-term lease from a bitcoin miner. On security, a paper showing that the three major providers’ encrypted reasoning blocks can be replayed and decoded put real-world data-exposure risk in the spotlight. And in hardware, China’s AgiBot climbed to the top of the humanoid market for the first half, confirming a shift in the robotics supply chain’s center of gravity.
