The first US federally regulated exchange where you can trade on the outcome of any event. Kalshi’s historical regulatory approval from the CFTC enables it to offer a new asset class called “event contracts,” which allow traders to take positions on whether a future event will happen or not. Kalshi aims to enable investors to trade on almost anything with economic relevance from Covid numbers to whether a bill will pass in Congress, broadening the historical definition of what a commodity derivative is and paving the way for the futures market to catch up to the novel risks facing the economy today. Kalshi is backed by Sequoia, Henry Kravis, Charles Schwab, and Y Combinator.

Immuta is The Data Provisioning Company, helping organizations safely and intelligently deliver governed data access to every consumer, human or AI. Since 2015, we’ve helped Fortune 500 companies and government agencies automate data provisioning at enterprise scale. As data demand surges and AI adoption accelerates, manual ticketing systems can’t keep up. Immuta removes these bottlenecks by automating the entire access lifecycle, from policy enforcement to request handling, delivery, audit, and recertification. What Immuta Does - Automates data provisioning by policy (birthright) and by request (governed self-service). - Writes policies once, enforces everywhere with native integrations across warehouses, storage, BI, and catalogs. - Delivers secure access in minutes, not months while maintaining continuous compliance. - Supports humans and AI agents that need governed data at machine speed. How We Help - Faster time-to-data: Reduce access delays from weeks to minutes with automated approvals and birthright access. - Less manual governance: Eliminate repetitive policy work and ticket triage for IT, stewards, and data owners. - Continuous compliance: Unified audit + automated recertification keep access accurate over time. - AI-ready provisioning: Governed access for LLMs, agents, and machine-driven workflows. Core Provisioning Workflows - Policy Authoring: Write once, enforce everywhere. Go from weeks of engineering to minutes. - Data Identification & Classification: Auto-detect and tag sensitive data to drive decisions. - Access Request Management: Governed self-service with automated approvals. - Behavior Monitoring: Detect unusual or risky access patterns in real time. - Unified Audit: See who accessed what, when, and why, in minutes, not days. The Outcome Organizations unlock data faster, reduce risk, and scale AI safely, with governed access delivered at the speed of need.
