The October funding round helped Kalshi expand its services to 140 countries. The company has grown rapidly since that expansion.
Kalshi now holds a valuation close to its main competitor Polymarket. Polymarket is seeking to raise funds at a valuation between $12 billion and $15 billion.
Both platforms allow users to trade on predictions about real-world events. Users buy and sell “yes” or “no” shares on outcomes ranging from elections to sports results.
Trading Volume Shows Market Growth
Kalshi and Polymarket have generated over $17.4 billion in combined trading volume since September. Data from DefiLlama shows Kalshi holds the larger share at 61.4% of that volume.
The two companies operate under different regulatory models. Kalshi functions as a regulated exchange under the Commodity Futures Trading Commission.
The CFTC oversight allows Kalshi to offer event contracts to U.S. users with legal clarity. The platform accepts fiat currency and targets both retail and institutional traders.
Polymarket takes a different approach using blockchain technology. The platform operates as a decentralized information market where users wager cryptocurrency on yes-or-no outcomes.
Platform Integrations Expand Reach
Both platforms have secured multiple integrations with major tech companies. Google Finance has integrated both Kalshi and Polymarket into its services.
Kalshi has also partnered with Robinhood, Elon Musk’s xAI and Grok, and the Pyth Network. These integrations happened over recent months.
Polymarket has arranged partnerships with MetaMask and Yahoo Finance. Some of these integrations are still in planning stages.
Polymarket faced regulatory restrictions that barred U.S. residents from using the platform since 2022. The platform returned for U.S. users earlier this month in Beta Mode.
Polymarket plans to make a full return to the U.S. market later this month. The timing aligns with the competitive pressure from Kalshi’s rapid growth.
The prediction market sector has attracted strong investor interest in 2024. The $1 billion funding round for Kalshi came from firms that previously invested in the company.
Kalshi’s valuation doubled in just one month between funding rounds. The company’s regulated status provides a path for mainstream adoption in the U.S. market.
