An investigation reported on 12 November says AI helped hackers gain access to organisations, with the article's headline citing 10 unnamed victims. The body says there were 25 operations against at least 19 organisations between August and September, with humans assigning targets and able to steer the AI. The article is not specific to crypto and gives no details of losses or affected platforms.
A 14 November cross-check on Solana found 31 program-retired validator identities still voting, together representing about 15% of active stake. The article says smaller validators' ability to replace the support previously provided by the Solana Foundation remains unresolved.
BitMine chairman Tom Lee argues that an AI market selloff and Anthropic's IPO, with its cash demands, are adding pressure to crypto markets, alongside recent hacks. The article is brief and gives no prices, amounts or timelines to verify the claims. It frames these pressures as evidence of how closely modern financial markets are linked.

In an Unchained Premium episode, Aztec co-founder Zac Williamson discussed Tierra, the V6 upgrade to Aztec's private layer 2 on Ethereum. He described an AI audit harness that found critical vulnerabilities in Aztec's cryptographic libraries, and a privacy pools-style design that lets users prove funds are unconnected to flagged Lazarus Group deposits.
Cobra, the pseudonymous owner and maintainer of bitcoin.org, says he has never seen bitcoiners so demoralised after a brutal bear market. He highlights several tailwinds for bitcoin in the short term while stressing that holding it is extremely risky at present. The headline also says he warns that AI threatens bitcoin self-custody as a winter looms, though the excerpt available does not detail that argument.

OpenAI has introduced ChatGPT Wallet on 13 November 2026, letting its persistent AI agents, called dots, complete purchases for eligible US ChatGPT Pro users. OpenAI works with American Express, Mastercard and Visa, and the payment network issues a token in place of the card number, so neither the merchant nor the agent sees the card details. OpenAI does not hold funds or act as a bank, and it has not disclosed any fee for merchants.
XRP Ledger activity has reached new November highs, with batch and ticket metrics both climbing to fresh peaks. The article points to these features as the main drivers of the surge in network use. It gives no specific transaction counts or price impact.

BeInCrypto's research unit tracked 6.4 million x402 agent payments on Solana and Base between 23 July and 26 August 2026, totalling $119,947. Most transfers were under one cent, and no news product appeared in the top ten most-called paid resources, which were dominated by searches and data checks.
The Federal Reserve's November Financial Stability Report puts the largest US bank holding companies' exposure to AI infrastructure firms at close to $1 trillion. Borrowing for advanced computing infrastructure passed $680 billion by October, about five times the $130 billion raised in all of 2023, and leases yet to start exceed $1 trillion. The Fed flags 'circular financing' between tech giants and developers and says the banks' AI-linked exposures face the annual supervisory stress test.

Bitcoin fell back from above $81,000 after an earlier attempt at $87,000, with macro pressure, rising inflation and higher Fed rate-hike odds cited as drivers. ChatGPT said Bitcoin is no longer in a confirmed bull market after losing its 50-week moving average, with price heading toward the $66,000 area. Grok and Perplexity called it a sharp but normal correction, though Perplexity noted the bull case is invalidated until the price reclaims lost levels.
Alameda Research Ventures put $500 million into Anthropic in 2021 for nearly 14%. The FTX bankruptcy estate sold those holdings for about $1.34 billion in 2025, and the article estimates the stake would now be worth around $37 billion at the expected $83 opening price. Anthropic's Nasdaq listing, under the ticker ANT, is expected around 19 November at a range of $70 to $78 per share.
A Satoshi-era bitcoin wallet that was served with a court notice in a $260 billion lawsuit has moved 75 BTC, worth roughly $5 million. The coins had sat untouched since 2011. The transfer also spent the tiny payment that had been used to deliver the court notice to the address in May.
MEGA, formerly MegaETH Foundation, reduced its headcount by about 20% on November 13, three days after allocating $30 million from its existing treasury to new products.

Its largest planned launch is an AI inference marketplace due in December, built on the MegaETH chain.
Trezor CTO Tomáš Sušánka says SHRINCS, the leading post-quantum signature proposal for Bitcoin, is difficult for hardware wallet makers because its stateful option needs precise state tracking to prevent fund theft. Trezor is considering making the larger, slower stateless signatures the default and hiding the stateful option in advanced settings. He also said hardware devices need post-quantum firmware authentication, which the Trezor Safe 7 already supports.
Contracts selling power to a 4% slice of global bitcoin mining at $44 per megawatt-hour expire on 31 December 2027, and Paraguay's state utility says that date is final.

In a Bitcoin Magazine BMTV interview, Mark Suman, co-founder and CEO of Maple AI, says the product is built on open-source code and encryption so that its own team cannot read chats. He argues that users should verify rather than trust the company, and that data should stay encrypted throughout the pipeline, including when using open-weight models. He also discusses ads influencing AI answers, agents approving their own budgets, and paying for the service with Bitcoin.
Giulio Rebuffo, Erigon's former CTO, announced on X on 13 November that he has joined the Ethereum Foundation to work on "applied AI x Client Dev" alongside the technical teams and management. The hire follows at least eight high-profile exits from the foundation this year, and Vitalik Buterin has argued for months that AI-written code should be paired with more testing and formal verification.
