Polymarket calls Peltola winner in Alaska Senate race after pricing Sullivan as heavy favorite
Prediction market Polymarket declared Democrat Mary Peltola the winner in Alaska's Senate race on Saturday, even as official vote counting remained contested. Days earlier, both Polymarket and Kalshi had priced Republican Daniel S. Sullivan as a heavy favorite, with implied payouts of $9,140 on a $100 bet against Sullivan at Polymarket and $7,794.16 at Kalshi. The reversal underscores how political prediction markets can rapidly reprice as new information emerges.
The flip from Sullivan-heavy pricing to a Peltola call is exactly the pattern state attorneys general in Ohio and Tennessee cite in arguing event contracts amplify sentiment rather than predict outcomes. Kalshi and Polymarket now face a live test of whether their scandal-driven repricing proves prescient or simply reactive. A correct Peltola call weakens the gambling-label claim; a reversal would arm litigators before likely 2027 proceedings.
Millions of retail users entered through Bloomberg and CBS News embeds this cycle without hedging tools, so any miss becomes a consumer harm story. Senators Warren and Curtis have demanded internal trading data under bipartisan deadline, keeping platform credibility under direct congressional scrutiny. The state bans in Maryland and Nevada already show the jurisdictional map remains fractured regardless of federal performance.
