Source: Kalshi / Polymarket via DeFi Rate, observed Oct 7, 7:09 PM ET. Kalshi prices each series. Polymarket and Polymarket US have no series-winner market in our feed, so their price is the team’s chance to reach the next round, which only the series winner does; “not listed” means that app has no such price in our feed. Gemini’s MLB markets aren’t in our price feed yet. Our figure averages the apps that price the team. A price button opens that app through DeFi Rate’s partner link (Polymarket’s opens Polymarket US in the US), not the market itself.

“Price to buy” is the venue’s current ask; “last trade” is the most recent trade and may not be available now. We don’t yet measure how many contracts are available at a price, so large orders may fill higher. Est. fee uses Kalshi’s published taker-fee formula, per contract in a bundle; other venues’ fees aren’t in our feed. DeFi Rate may earn a commission when you open an account through these links. 18+ (21+ in some states).
