Kalshi’s Global Rise and Market Dominance
Kalshi allows users to trade on real-world event outcomes ranging from elections to inflation reports. It recently announced that it is expanding access to its platform in over 140 countries. This international push is supported by the platform’s skyrocketing trading volumes, expected to reach $50 billion in annualized volume this year, a steep rise from $300 million last year.
- Kalshi now holds over 60% of the global prediction market share, overtaking rival Polymarket.
- In the last week of September alone, it recorded $956 million in trading volume, nearly double that of Polymarket, according to Dune data.
Founded in 2018 by Tarek Mansour and Luana Lopes Lara, Kalshi operates under the regulatory oversight of the U.S. Commodity Futures Trading Commission (CFTC), a major differentiator from its decentralized and unregulated counterparts. This legal status has helped attract both institutional traders and crypto-native investors, who are increasingly seeking regulated ways to participate in event-based financial products.
Backing From Wall Street and Web3
Kalshi’s latest funding reflects growing investor interest in crypto-aligned fintech ventures. According to reports, venture capital investments in crypto-linked projects have already reached $17 billion in 2025, outpacing last year by over $7 billion.
Alex Immerman from Andreessen Horowitz praised Kalshi’s compliance-first approach, stating the founders took “the difficult but more responsible route” in seeking regulation under the CFTC. This move is seen as essential in bridging the gap between traditional finance and blockchain-powered innovation.
Sports Betting Boom and Platform Integrations
A major driver behind Kalshi’s surge is the explosive growth of the sports betting industry in the United States. Since the Supreme Court overturned a federal ban in 2018, sports betting has become a $13.7 billion market. Prediction platforms like Kalshi are capitalizing on this momentum by offering contracts on game outcomes, often in the form of parlays.
- Kalshi has partnered with Robinhood and Webull, allowing users to access prediction markets directly through their trading apps.
- According to analysts, Robinhood users now account for a large share of Kalshi’s total trading volume.
Regulatory Hurdles and Competitive Pressure
Despite its regulatory status, Kalshi is not without challenges. It is currently facing lawsuits in several U.S. states alleging violations of local sports betting laws. While it cleared a key regulatory milestone with the CFTC earlier this year, state-level scrutiny threatens to complicate its path forward.
Meanwhile, competitor Polymarket is also catching up. In July, Polymarket acquired QCX, a CFTC-licensed derivatives exchange, and recently received a no-action letter from the regulator, potentially allowing it to operate legally in the U.S. This move could narrow Kalshi’s current regulatory edge.
Crypto Innovation and Future Plans
Kalshi is also pushing deeper into the crypto space. Through a partnership with ZeroHash, the platform already accepts crypto deposits. Its new crypto lead, John Wang, revealed plans to build new financial primitives and bring prediction markets further onchain.
At the Solana APEX conference, Wang called crypto “essential to fulfilling that vision,” encouraging developers to pitch ideas for tokenizing Kalshi positions and pushing market data onchain.
CoinLaw’s Takeaway
I’ve been watching the prediction market space for years, and Kalshi’s rise is unlike anything I’ve seen. What makes this moment big isn’t just the dollar signs or flashy backers. It’s how Kalshi is blending real financial regulation with Web3-style innovation. In my experience, most startups pick one side or the other. Kalshi is doing both, and doing it fast. The global expansion, the Robinhood integration, and their full-on embrace of crypto are game-changers. But the real test? Whether they can navigate the tricky legal waters ahead. If they do, Kalshi might just define the future of betting on real-world events.
