Kalshi operates a platform where users trade on the outcomes of real-world events. The company has focused on regulatory compliance in the U.S. market since its launch.
Growth Metrics Show Strong Performance
The platform’s trading volume has grown rapidly over the past year. Weekly trading volume recently crossed $1 billion, more than triple the volume from a year ago.
Kalshi is on track to reach $50 billion in annualized trading volume. Last month, the company captured over 60% of global prediction market share.
This market share surpasses competitor Polymarket. The platform now operates in over 140 countries following its international expansion.
The company has formed partnerships with major trading platforms. Users can already trade event contracts through Robinhood and Webull.
Expansion Plans Take Shape
Kalshi’s Head of Crypto John Wang outlined expansion goals to The Block. The platform aims to integrate with every major crypto app within 12 months.
The company is adding new contract types to attract users. This includes sports-related contracts such as NFL betting markets.
The international push represents a major shift in strategy. Kalshi previously concentrated on building a compliance-first approach in the United States.
Competitor Activity Heats Up
Polymarket announced its own funding news the same week. Intercontinental Exchange, the parent company of the New York Stock Exchange, invested $2 billion in the platform.
The investment values Polymarket at $9 billion post-money. Polymarket is working to re-enter the U.S. market after receiving approval from the CFTC.
The two platforms have taken different regulatory approaches. While Kalshi built its business around U.S. compliance first, Polymarket gained traction internationally before seeking U.S. approval.
Regulatory Questions Remain
Prediction markets operate in a complex regulatory environment. These platforms allow trading based on event outcomes, which sits between traditional betting and financial markets.
Some critics have described these platforms as untaxed gambling. The platforms face lighter regulations compared to traditional betting companies in many jurisdictions.
As trading volumes increase, regulatory scrutiny may grow. Kalshi will need to manage compliance across multiple countries as it expands globally.
The platform’s compliance-first approach may provide an advantage. This strategy has allowed Kalshi to operate openly in the U.S. market from the start.
