GoKawiilBank of America hired 1,000 contractors to fix flaws found by Anthropic's Mythos AI
Bank of America CEO Brian Moynihan told CNBC the bank brought on 1,000 outside contractors in the second quarter to patch software vulnerabilities exposed by advanced AI models, including Anthropic's Mythos. Those contractors remain in place alongside the bank's existing 3,000-person team, and Moynihan said the bank spent over $200 million in the third quarter on remediation and related anti-money-laundering compliance work.
GoKawiil's interpretation of the reporting above, not reported fact.
The disclosure offers a rare concrete figure for how much a major financial institution is spending to defend against AI systems capable of finding decades-old software flaws, suggesting other large firms could face similar hidden costs. Moynihan's comments also illustrate a tension he describes directly: the same vendors selling banks AI tools are also the ones whose models can expose weaknesses, forcing defensive spending even as AI promises productivity gains. His assurance that the spending is temporary implies markets may be pricing in ongoing risk that the bank disputes.
- Bank of America added 1,000 contractors in Q2 to patch vulnerabilities flagged by AI models like Anthropic's Mythos.
- The bank spent over $200 million in Q3 on software remediation and anti-money-laundering compliance combined.
- Moynihan says the spending surge should ease once patching work is complete, despite a share price drop of up to 8%.
