The Regulatory Moat Play
Kalshi made history in 2020 by becoming the first Designated Contract Market (DCM) approved by the CFTC specifically for event contracts. This puts them alongside established exchanges like CME and ICE—a status no crypto competitor like Polymarket can claim.
The May 2025 CFTC decision to drop their appeal on political event contracts was a watershed moment. It removed the final regulatory barrier and unlocked massive growth in their highest-volume category.
Business Model
Kalshi operates a two-sided prediction marketplace with a maker-taker fee structure:
- Binary contracts priced $0.01-$0.99 (price = market probability)
- Correct prediction pays out $1 per contract
- Taker fees range 0.07%-7% (sliding scale based on probability)
- Maker orders are free (incentivizes liquidity)
Unlike sportsbooks, Kalshi doesn't bet against users—they simply match opposing predictions and take transaction fees. This is a sustainable, scalable revenue model.
Growth Metrics
The numbers tell the story:
- Trading volume: $5.81B monthly (Nov 2025), up 1,000%+ YoY
- Users: ~2 million (10x growth in one year)
- Revenue: $600-700M annualized run rate
- Markets: ~2,800 active (politics, sports, economics, weather, entertainment)
Funding & Backers
Kalshi's investor roster reads like a who's who of elite capital:
- Series E (Dec 2025): $1B at $11B valuation, led by Paradigm
- Key investors: Sequoia Capital, a16z, Y Combinator, CapitalG, Multicoin Capital
- Strategic angels: Charles Schwab, Henry Kravis
The rapid valuation climb from $5B to $11B in 2025 shows institutional capital flooding into the prediction market space.
Investment Thesis
Bull Case
- Regulatory moat: Only US-regulated prediction market—this is nearly impossible to replicate
- Network effects: More users = more liquidity = better prices = more users
- Political contracts unlocked: Highest engagement category now fully operational
- Mainstream adoption: CNN partnership signals prediction markets going mainstream
- Revenue model works: Sustainable fees, not gambling on user losses
Bear Case & Risks
- State-level legal battles: Massachusetts lawsuit, Nevada reconsidering, Maryland denied injunction
- Gambling classification risk: NY lawsuit to prevent gaming commission classification as illegal gambling
- Competition: Polymarket (crypto-native), potential new entrants if regulation loosens
- Regulatory uncertainty: What CFTC gives, future administrations could restrict
Founding Story
Founded in 2018 by Tarek Mansour and Luana Lopes Lara, Kalshi was born from frustration. While working as financial analysts, the founders watched investors struggle to hedge against macro events like Brexit. They envisioned a regulated marketplace where anyone could take positions on real-world outcomes—and spent years navigating CFTC approval to make it happen.
The Bottom Line
Kalshi is a bet on prediction markets going mainstream in America. Their regulatory moat is real, their growth is explosive, and their backers are elite. The question isn't whether prediction markets have value—it's whether Kalshi can navigate state-level legal challenges while maintaining their federal advantage.
