OpenAI rolled out new personal finance features in ChatGPT on Friday, enabling U.S. Pro subscribers to link bank and investment accounts via Plaid. The tool covers 12,000+ institutions and can analyze spending, subscriptions, and upcoming payments, while viewing balances and transactions without being able to move funds or see full account numbers. Pro access costs $200 a month, and OpenAI says synced data is deleted within 30 days after an account is disconnected.

Antseed said it launched a decentralized, peer-to-peer AI marketplace on May 15 that links AI users directly with model providers and removes centralized intermediaries. The network starts with 20 providers and supports instant USDC settlement to providers' wallets with 0% platform markups. Antseed also says the system is account-free, aiming to let next-generation AI agents transact without centralized authorization.

Cerebras Systems surged in its Wall Street debut on Thursday, ending its first session with a market cap just under $100 billion before trading lower on Friday. The company sells dinner-plate-sized custom ASICs and says its WSE-3 is 57 times larger than the biggest GPU and packs 50 times more transistors. Cerebras also runs its chips through its own cloud data centers, with a $20 billion OpenAI cloud deal running through 2028 and sales said to be booked out into 2027.

On May 15, 2026, the FCA, the Bank of England and HM Treasury said frontier AI models are raising cyber risks for regulated financial firms and financial market infrastructures. They urged firms to reinforce operational resilience and cybersecurity to counter AI-driven attacks that can be faster, more scalable and lower cost.

A Goldman Sachs report forecasts a $7.6 trillion AI capital spending baseline by 2031, with costs highly dependent on whether AI chips remain useful beyond three years. Industry voices from StealthEX and Cysic say DePINs can cut GPU costs but face internet latency limits, making them better suited to batch jobs unless verifiability improves via TEEs and ZK attestations. They also point to onchain credit platforms like Maple and Centrifuge as potential lenders for $5M–$50M data center deals, though legal, oracle, and regulatory hurdles remain.

Google’s Threat Intelligence Group (GTIG) said on May 11, 2026 it documented what it calls the first AI-developed zero-day: a two-factor authentication bypass in a widely used open-source web administration tool. Google said it coordinated with the vendor to patch the issue before a broader exploitation campaign began. GTIG also described a wider rise in AI-assisted activity across state-linked and criminal groups, including risks to AI tooling dependencies used in crypto systems.

Moonpay said it acquired Dawn Labs on May 11, 2026 and introduced Dawn CLI, an AI-native trading tool that turns plain-English strategy descriptions into automated execution on supported venues.

Moonpay also stated it serves 30 million customers across 180 countries as it expands into AI-native financial infrastructure.
