Polymarket and Kalshi's combined monthly volume hit ~$24B by April 2026, up from under $5B in September 2025. But lawsuits, including a June 2026 case alleging Polymarket paid influencers to fake trades, expose a deeper problem: no objective way to verify trades are real or outcomes are resolved fairly. Newer platforms like Opinion Labs and Rain Trade are trying to fix this with cryptographic verification and hybrid AI/human resolution.
