Polymarket's mindshare, measured by Kaito AI as share-of-voice in crypto Twitter's information markets narrative, has recently slipped below 60% amid rising buzz for rival Kalshi despite the platform's record weekly volumes exceeding $1.9 billion. The February 2026 Kaito partnership launched dozens of attention markets—including self-referential bets on Polymarket's own visibility—while a reported $400 million funding round at a $15–20 billion valuation and U.S. regulatory expansion plans have driven institutional interest and media coverage. Recent fee adjustments have shifted activity toward larger traders, tempering retail-driven social signals, though rumors of a token generation event and app store momentum could provide fresh catalysts before the December 31 resolution.
