Polymarket's mindshare, measured by Kaito AI's share-of-voice metric in crypto Twitter's Info Markets narrative, recently slipped below 60% as rival Kalshi captured more social attention, even as Polymarket posted weekly volumes exceeding $1.9 billion and pursued a potential $20 billion valuation. Key drivers include the February launch of attention markets via the Kaito partnership, U.S. exchange rollout in May, recent high-profile marketing hires, and annualized revenue surpassing $1 billion. Fee adjustments have shifted activity toward institutional flows, tempering retail buzz, while competition from Kalshi and emerging platforms adds pressure. Upcoming catalysts include NFL season trading in September, November midterms, potential token generation event rumors, and app store positioning that could influence public perception by year-end.
