Prediction market platform Kalshi has launched Combos, a feature allowing users to bundle multiple event outcomes into single parlay-style contracts.
The feature processed over $100 million in volume during its first week, according to Tarek Mansour, Kalshi’s co-founder and chief executive officer, who announced the full rollout on social media.
The launch comes as the platform hit a daily volume record of approximately $340 million and experienced 50% app growth in November alone.
He explained the reason why Combos is gaining traction rapidly, stating in a <a href="https://www.linkedin.com/posts/mansourtarek_the-wait-is-over-combos-are-officially-live-activity-7406447492554248192-zMBu/" target="_blank" rel="noopener noreferrer nofollow">post on LinkedIn</a> that it was due to “better pricing.”
According to Mansour, “In traditional financial markets, traders bundle multi-leg options instead of buying separately to get better prices. Combos offer the same price improvement. And like with all our other markets, there is no house: when you submit a Combo, traders compete in the open market to take the other side.”

Kalshi has experienced explosive growth over the past year, and its rival Polymarket has also seen tremendous growth, making it a good year for prediction markets. The platform recently closed a <a href="https://news.kalshi.com/p/kalshi-11-billion-valuation-series-e" target="_blank" rel="noopener noreferrer nofollow">$1 billion Series E funding</a> round at an $11 billion valuation in early December.
For some time, Kalshi had the sole claim to Commodity Futures Trading Commission (CFTC)-regulated status.
However, Polymarket recently secured a CFTC clearance, increasing the competition in the space.

The platform is deploying its recent funding toward expanded brokerage integrations and news partnerships, including live integration with CNN and a planned 2026 partnership with CNBC.
In October 2025, Kalshi announced alongside its $300 million Series D funding, that it had made prediction markets accessible in over <a href="https://news.kalshi.com/p/kalshi-hits-5-billion-valuation-amid-international-expansion" target="_blank" rel="noopener noreferrer nofollow">140 countries</a> with shared liquidity pools and launched blockchain initiatives, including the Kalshi Eco hub with partnerships across Solana and Base networks.
Crypto platform <a href="https://x.com/phantom/status/1999442547039756491" target="_blank" rel="noopener noreferrer nofollow">Phantom</a> announced on December 12, 2025, that it was introducing prediction markets powered by Kalshi to its users, allowing them to trade on what’s trending in sports, politics, crypto, culture, and others.
According to Cryptopolitan <a href="https://www.cryptopolitan.com/coinbase-to-launch-prediction-markets/" target="_blank" rel="noopener noreferrer nofollow">reports</a>, Coinbase is also planning to launch its own in-house prediction market powered by Kalshi’s technology.
On December 11, <a href="https://news.kalshi.com/p/coalition-for-prediction-markets-launch" target="_blank" rel="noopener noreferrer nofollow">Kalshi joined</a> Crypto.com, Coinbase, Robinhood, and Underdog in launching the Coalition for Prediction Markets, which it called “a new national organization dedicated to preserving safe, transparent, and federally supervised access to prediction markets.”
The organization aims to advocate for consistent federal oversight and respond to fragmented state-level challenges.
With the current trajectory of the leading platforms, analysts predict that prediction markets could grow into a trillion-dollar asset class as they continue to gain mainstream acceptance.
