A Bitcoinwallet that had not moved in more than 11 years sent out roughly 5 BTC worthabout $400,000 yesterday (Wednesday), after its pseudonymous owner uploaded thecontents of an old college computer into Anthropic's Claude and let the AI siftthrough more than a gigabyte of files. The address14VJySbsKraEJbtwk9ivnr1fXs6QuofuE6distributed the coins across five transactions on May 13, according to publicblockchain records.Therecovery, posted on X by an account called Cprkrn, drew more than 11 millionviews within hours and prompted reactions from prominent crypto figuresincluding Castle Island Ventures partner Nic Carter and Base creator JessePollak.HOLY FUCKING SHIT OMG CLAUDE JUST CRACKED THIS SHIT, THANK YOU @AnthropicAI THANK YOU @DarioAmodei NAMING MY KID AFTER YOU 😍https://t.co/gObNirRDpS https://t.co/ByTdIM4d20 pic.twitter.com/xB5LUJb6Pe— 🍜 (@cprkrn) May 13, 2026The casesits inside a broader trend of large language model deployment across cryptoinfrastructure, following work by Revolut engineers who built anAI-driven trading workflow with Claude in 30 minutes earlier this year.What Claude Actually DidDespite the"OMG Claude just cracked this shit" framing in the original tweet,the AI did not break Bitcoin's encryption. Cprkrntold Cointelegraph in a follow-up interview that he had already located ahandwritten mnemonic in an old notebook before turning to Claude.The AI thensearched two Macs, two external hard drives, an Apple Notes export, an iCloudMail inbox, a Gmail inbox and X direct messages, totaling more than a gigabyteof unstructured data, according to the user's account.I tried like 7 trillion passwords lmfaoFound this old pneumonic a few weeks ago that ended up being the old password before I changed itThought I was screwedLast ditch effort dumped my whole college computer into ClaudeIt found an OLD wallet file that the pneumonic…— 🍜 (@cprkrn) May 13, 2026On thecollege computer, Claude located a wallet backup file from December 2019 thatpredated a password change Cprkrn had made on blockchain.info, and the mnemonicdecrypted that older file.Claude alsoidentified a logic detail in the open-source recovery tool BTCRecover, whichconcatenates a sharedKey value with the user password during decryption. Totalcompute spend came to roughly $15, according to a summary the model produced.The recovered password, Cprkrn later disclosed publicly, was"lol420fuckthePOLICE!*:)".Wallet Recovery IndustryFaces a New Cost CurveCommercialrecovery services have for years charged premium prices for the technicalexpertise needed to handle legacy Bitcoin Core wallets. Cprkrn said he hadspent roughly $250 per failed attempt at such services before turning to AI. Firmsincluding Wallet Recovery Services and KeychainX market brute-force passwordrecovery and typically take percentage cuts of recovered funds.The casefits a wider thread of AI deployment across crypto-adjacent functions. ATFXpartnered with data firm KX in late 2025 to deploy an AI-driven MCP server forreal-time trading data, while LSEG connected its market data feeds to ChatGPTin December 2025. BitgetWallet launched its Smart Money feature earlier, tracking high-performingaddresses with AI to surface trading signals.In thiscase, the user worked through Claude's consumer interface with standard fileuploads and tool use, not a purpose-built API integration or agent-ready exchange architecture. If theaccount is accurate, the same workflow could in principle be replicated by anyholder of a legacy wallet with surviving file backups.The Dormant SupplyQuestion ReturnsIndustryestimates of inaccessible Bitcoin vary widely. Cointelegraph cited reportsputting between 2.3 million and 4 million BTC as unrecoverable, or roughly 11%to 19% of the 21 million maximum supply. Glassnodedata shows about 34% of circulating supply, more than 7 million coins, sits inwallets that have not transacted in years. A 2020 Chainalysis estimate putconfirmed lost coins at approximately 3.7 million.FidelityDigital Assets, citing Glassnode, reported in 2025 that more than 566 BTC perday were aging into the "ancient" category of coins untouched for 10years or more. Miners produce only 450 BTC per day following the April 2024halving. Thedifferential between dormant accumulation and new issuance has been cited asstructural support for Bitcoin prices, on the assumption ancient coinsrepresent lost supply.There is noevidence the Cprkrn case meaningfully shifts those estimates. But thedemonstration that consumer AI tools can compress recovery costs fromprofessional service rates to $15 changes the cost-benefit math for holders offorgotten wallets.Forensics or Cracking?Experts Push BackWalletrecovery experts toldDecrypt the screenshots posted by Cprkrn showed file forensics, notcryptographic work. "Claude'slikely role was sorting through large amounts of historical data andidentifying clues tied to older wallet credentials or password formats,"one expert told the outlet, adding that the case is "not so much apassword cracking thing as it is a forensics sorting."Theskepticism extended to Reddit. "Claude didn't do anything other thansearch his files," userMeteorSwarmGallifrey wrote in the technology subreddit, arguing the modelhad not done anything "groundbreaking." Othercommenters defended the use of AI for forensic triage across years ofunstructured personal data, noting that knowledge of how older Bitcoin Corewallet files persist as .bak backups is non-obvious to non-specialists.Anthropichas not commented publicly on the case.
