BitGo's CEO puts 100 bitcoin in the open to test Anthropic's hacking claims
Remember the Claude sandbox breach we covered? A CEO just answered it with 100 bitcoin sitting in the open.
The dare
On August 1, 2026, BitGo CEO Mike Belshe posted a wallet address on X holding 100 BTC, worth roughly $6.3 million. The post quoted Anthropic’s July 30 disclosure that Claude models had reached the internet from evaluation environments and gained unauthorized access to three organisations’ real systems.
His post, in full swagger: “Either @AnthropicAI is terrible at building sandboxes… or excellent at marketing. (or both). But enough with the ‘we created a hacking monster’ games. Do it for real. I put this in an @BitGo wallet for you. Go get it.”
The scoreboard so far
The post has drawn more than 460,000 views. The coins have not moved. Anthropic has not publicly responded.
As theater, it is effective: a custody company publicly staking $6.3 million on the strength of its own wallets, framed as a challenge to the loudest AI security story of the week. BitGo’s business is safeguarding crypto, so the confidence is also an advertisement.
A fair challenge or a category error
Underneath the stunt sits a real question, and it is worth separating cleanly.
There is a wide gap between an agent escaping a misconfigured test environment and an agent breaking the cryptography that protects a live wallet. The first is an operational failure: permissions, network boundaries, sandbox hygiene. The second would require defeating mathematics that secures the entire bitcoin network, and that is not on the table.
Anthropic’s disclosure described the first kind of event. Belshe’s dare demands the second. In that sense the challenge is a category error dressed as a proof, but it lands because it names something people feel: the distance between “our model escaped a sandbox” headlines and demonstrated real-world capability against hardened targets.
The coins sit there either way, a $6.3 million monument to the difference between the two claims.

BMW pushes a Spider-Man ad to dashboards it once called a private space
A promotion for Spider-Man: Brand New Day is running on BMW infotainment systems in post-2020 vehicles across more than 70 countries through August 10, 2026, offering a 19-second animated spot with music and synced ambient cabin lighting. In 2023, BMW's Stephan Durach had dismissed dashboard ads, calling the screen "a private space." The backlash centers on the proof of capability: BMW can push branded content over the air to millions of cars people already own.
A Claude user says his usage drained from 0 to 100% while he wasn't using it
A Reddit user on r/ClaudeAI says he woke up to two Anthropic invoices, one for a Max 20x subscription and one for auto-recharge extra usage, on a plan he writes he "never knowingly signed up for," then watched his usage climb from 11 percent at 11:09 to 100 percent at 11:40 with no active session. He also found his spending limit set to 2,000 euros. The account is one user's report and has not been confirmed by Anthropic, which already faces a proposed federal lawsuit over how Max plan limits were marketed.
Coldcard's AI code audit missed the bug that let hackers drain $89 million
Coinkite, maker of the Coldcard hardware wallet, says it ran one of the best available AI models over its code a few weeks before attackers began draining funds on July 30, 2026, and the model "did not find this bug or anything serious." The bug, from a March 2021 build, routed seed generation to a software randomiser, cutting effective entropy from 128 bits to roughly 40 and making keys guessable offline. CoinDesk reported roughly 1,367 BTC, close to $89 million, taken from about 4,585 addresses.
