[Kalshi CEO: Official Launch of Combos Feature, Single-Day Trading Volume Hits Record $340 Million] Kalshi co-founder and CEO Tarek Mansour announced on the X platform that Kalshi has officially launched the Combos feature for all users. The trading volume for the Combos feature exceeded $100 million last week. Kalshi's app saw a 50% growth rate in November, and yesterday's trading volume set a new record of approximately $340 million. The Combos feature is similar to bundling multi-leg options in traditional finance, offering better purchase prices. Combos trading has no 'market maker'; when users submit a Combo, traders compete in the open market to complete the transaction.
