In response to customer complaints, senior Polymarket engineer Mustafa Aljadery said in a post on X that the KYC checks targeted customers accessing Polymarket’s application programming interface “in certain jurisdictions” and that Polymarket “remains kyc free for all other users.”
But if Polymarket doesn’t start enforcing its policy on prohibited jurisdictions, it risks regulatory action. Regulators in the Netherlands and other countries have already threatened it with penalties if it continues to provide an illegal gambling platform to their residents.

The firm is letting users open a dedicated agentic trading account, separate from the rest of their portfolio, meaning the agent only has access to the funds deposit into its account.
Users get push notifications any time the agent makes a trade and can see a real-time activity feed and P&L directly in the Robinhood apps. The agent can be disconnected at any time with the tap of a button.
Customers can also empower agents to spend on their behalf by connecting them to Robinhood Banking’s MCP server. During setup, users connect the agent to a dedicated virtual Robinhood Gold Card, set a specific spending limit that only they control and choose whether to require manual approvals or not.
From: Robinhood customers can now let AI agents make trades and credit card purchases.

Top UK law firm Pinsent Masons has been admonished by London’s High Court after its lawyers made false submissions to a judge based on AI, the latest high-profile mistake resulting from the industry’s increasing use of the technology.
Pinsent Masons misled the court twice by inaccurately citing a statute in relation to a routine insolvency application, an error that was only picked up when the judge queried the reference. Judge Mark Mullen said in his ruling that work pressure did not excuse a “failure to check the accuracy of the material”.
The submissions were made by a junior lawyer, referred to as “LA” in Mullen’s judgment, with oversight from a senior associate and partner. In their witness statements, the supervisors said that they were not aware that the junior lawyer had used AI.

Scams using AI generate an average of $3.2 million per operation, compared to $719,000 for those that don’t, according to crypto monitoring firm Chainalysis’ 2026 Crypto Crime Report. That nearly fivefold increase in revenue per scam is driven by AI’s ability to automate impersonation — a tactic that saw 1,400% growth this year, according to the company.

Founded by Circle co-founder Sean Neville, Catena is a banking and governance platform for AI agents, providing them with programmable financial infrastructure covering accounts, payments, stablecoin rails across ten chains, and yield on idle balances, accessed through an MCP server, a REST API, or a command line.
As it opens up private access to its platform, the firm has revealed that it has raised $30 million in a round co-led by a16z crypto and Acrew, with participation from Breyer Capital, General Catalyst, QED, Oak, Fin, and IDG Capital.
The money – which brings total financing to $48 million – will be used to build the platform, earn the licences, and hire the people required to serve agents and their operators.
Meanwhile, the Office of the Comptroller of the Currency has accepted for filing Catena’s application for a National Trust Bank charter.

Circle’s agent tools include Circle CLI, a command interface that lets developers and potentially AI agents build applications on top of Circle’s platform suite, with a focus on wallets, payments and policy management for agents. The other products include: Nanopayments, a protocol that supports USDC transfers designed for large volumes of machine-to-machine payments; Agent Wallets, which are designed for AI agents to hold, send, and manage funds autonomously within predefined guardrails; and Agent Marketplace, a directory of agentic services that both humans and AI agents can browse and integrate to enable agents to discover and pay for services programmatically.

Cryptocurrency companies are preparing for the threat that powerful quantum computers could soon be able to hack the security at the heart of the global industry, including breaking the critical code that underpins bitcoin.
The risk to crypto posed by fast-developing quantum technology — which exploits the way the physics of matter works differently at atomic and subatomic levels — was once considered a distant possibility, with bitcoin widely seen as unhackable.
But digital assets firms are speeding up their preparations for a “post-quantum” age, as tech companies slash the timelines for developing practical quantum computers to as soon as 2030.
“The threat has moved from theoretical to credible,” said Ayo Akinyele, head of engineering at RippleX, the blockchain development arm of crypto group Ripple.
