US Senate Democrats accuse Elon Musk-owned social media platform X of granting preferential treatment to prediction market Polymarket. In a joint letter first disclosed by Semafor, Democratic Senators Catherine Cortez Masto (Nevada), Adam Schiff (California), Jacky Rosen (Nevada), and Richard Blumenthal (Connecticut) wrote: "Typically, X allows users to report ads for multiple reasons. However, when users attempt to report Polymarket ads via X's standard interface, no reporting options are available. This issue does not arise for other ad types, including those from Kalshi." The letter, which includes screenshots, alleges this seemingly unfair special treatment raises questions about whether X is trying to provide Polymarket with an improper competitive advantage, thereby benefiting the US President and his family. Donald Trump Jr. has invested in Polymarket and serves as an advisor for the platform.

Beating AI News Flash: Moonshot AI’s Kimi launches a game development and creative workflow solution, aiming to transition AI agents from assisting programming to end-to-end game production, covering the entire workflow from gameplay design, 3D modeling, engineering development to publishing and operations. This time, Kimi does not only generate code or art assets—it operates directly within game engines. Built on K3.1 Pro, Kimi Code, and Kimi Work, the AI can use plugins to control professional tools including Unity, Unreal Engine, and Blender, modify existing game projects, even run games independently, review test recordings, and refine fixes based on identified issues. For instance, game designers only need to provide reference images, videos, and gameplay requirements, and Kimi can build a 2.5D action game prototype with mechanics like sword swings, dodges, and blocks using Godot. Officials stated that even users without programming experience can create a playable game prototype in 1–2 days. In another demo in partnership with Unity China, Kimi worked continuously for 20 hours without human intervention, reproduced the original work, and delivered a native project ready for further development. Moonshot AI is also expanding its focus to game publishing and long-term operations: batch producing ad materials, analyzing player feedback, managing community content and localization, and even integrating AI dialogue capabilities into game NPCs via APIs.
