Yes, Kalshi is legit. It is the first and only prediction market exchange regulated by the U.S. Commodity Futures Trading Commission (CFTC) as a Designated Contract Market (DCM), making it fully legal to trade in all 50 U.S. states. Since launching in 2021, Kalshi has grown into the largest regulated prediction market in the country, with weekly volume regularly clearing hundreds of millions of dollars across politics, sports, economics, and cultural events. This deep dive covers how Kalshi is regulated, how it makes money, what you can trade, the fees, the risks, and why serious traders now treat it as a legitimate asset class rather than a novelty.
What Is Kalshi?
Kalshi is a federally regulated event-contract exchange based in New York. Traders buy and sell binary contracts that pay out $1.00 if a real-world event happens and $0.00 if it does not. A contract trading at 67 cents implies the market believes there is roughly a 67% chance the event resolves “Yes.” Contracts settle in cash, are held in a U.S. brokerage-style account, and clear through Kalshi’s own CFTC-registered Derivatives Clearing Organization (KalshiEX).
Founded by Tarek Mansour and Luana Lopes Lara, both MIT graduates and former options traders, Kalshi spent four years working with regulators before launch. That regulatory-first approach is the single biggest reason it is considered legitimate: unlike offshore competitors, Kalshi cannot be shut down by U.S. authorities, cannot freeze U.S. customer funds without process, and is subject to the same customer-protection rules as a futures broker.
Is Kalshi Actually Legal? The CFTC Story
Kalshi’s legitimacy rests on its status as a CFTC-registered Designated Contract Market, the same category as the CME and ICE Futures. That designation means every contract listed on Kalshi is a federally regulated derivative, customer funds are held in segregated accounts, and the exchange is subject to routine CFTC audits, position-limit rules, and market-surveillance requirements.
The single most-litigated question was whether Kalshi could list political event contracts. In 2024, the CFTC attempted to block Kalshi’s congressional-control markets, arguing they resembled gaming. A federal district court ruled in Kalshi’s favor, and the D.C. Circuit affirmed that ruling on appeal. Since then Kalshi has offered election, Senate, House, gubernatorial, and presidential markets openly across all 50 states, including in states like New York, New Jersey, Massachusetts, Nevada, and Montana where competing platforms have faced state-level cease-and-desist orders. The upshot: when you trade politics on Kalshi, you are trading a federally regulated derivative, not placing a wager.
What You Can Trade on Kalshi
Kalshi’s contract catalog has expanded from a few dozen markets at launch to thousands of active contracts. The major categories:
- Politics: presidential and congressional control, individual Senate and House races, gubernatorial contests, foreign elections, cabinet nominations, and Supreme Court confirmations.
- Sports: single-game and season-long markets across the NFL, NBA, MLB, NHL, college football and basketball, tennis, golf, soccer, and UFC. Sports launched in early 2025 and is now Kalshi’s highest-volume category.
- Economics: Fed rate decisions, CPI prints, unemployment reports, GDP releases, recession odds, and jobs-report ranges.
- Crypto: Bitcoin and Ethereum year-end price ranges, ETF flows, and halving-cycle outcomes.
- Culture and entertainment: Oscars, Emmys, box office totals, album chart positions, Nobel Prizes, and Time Person of the Year.
- Weather and climate: hurricane landfalls, temperature records, and named-storm counts.
How Kalshi Makes Money
Kalshi is a for-profit exchange, and its revenue model is transparent — a rarity in the prediction-market world. It earns money in three ways:
- Trading fees: a small taker fee (typically 1–7 cents per contract, scaled to price) is charged on filled orders. Makers who add liquidity usually pay less or nothing.
- Interest on customer deposits: like every U.S. brokerage, Kalshi earns yield on the cash sitting in customer accounts, held at partner banks.
- Data and API licensing: hedge funds, media outlets, and research shops pay for real-time market data and settlement feeds.
The company raised a Series C in 2025 at a valuation reported north of $2 billion, backed by Sequoia, Charles Schwab, Peter Thiel, and Henry Kravis, among others. That capitalization matters for legitimacy: a well-funded, U.S.-regulated exchange with tier-one investors is not going to disappear overnight.
Kalshi vs Polymarket vs Offshore Books
| Factor | Kalshi | Polymarket | Offshore books |
|---|---|---|---|
| U.S. legal status | CFTC-regulated, legal in all 50 states | Legal in the U.S. as of 2025 after QCX acquisition, still ramping | Unregulated in the U.S. |
| Funding | USD via bank, debit, wire, ACH | USDC on Polygon; USD onramps improving | Crypto only, often high friction |
| Custody | Segregated U.S. brokerage accounts | Self-custody smart contracts | Custodial, opaque |
| Political markets | Yes, fully cleared by federal courts | Yes | Varies |
| Sports markets | Yes, growing rapidly | Yes | Yes |
| Consumer protections | CFTC segregation, dispute process | On-chain but limited recourse | Effectively none |
Fees, Withdrawals, and What to Watch Out For
Kalshi’s fee structure is transparent and published on its site. Fees are calculated as a function of contract price and are highest on 50-cent contracts (the point of maximum uncertainty). Depositing via ACH is free, debit-card deposits are instant with a small fee, and withdrawals to a linked U.S. bank typically clear in 1–3 business days with no charge.
The real risks are not regulatory — they are the usual market risks. Thin markets can have wide spreads. Resolution rules matter: read them before you trade, particularly on politics and sports where “when does this settle” and “what source is used” determine winners. And event contracts are winner-take-all: a 90-cent “Yes” that loses is still down 90 cents. Kalshi is legit, but it is not risk-free.
Bottom Line: Is Kalshi Worth Using?
For any U.S. resident who wants to trade prediction markets legally, Kalshi is the default choice. It is federally regulated, court-affirmed on politics, deep on sports and economics, and backed by serious institutional capital. The fees are reasonable, the withdrawals are clean, and customer funds are protected by the same segregation rules that apply to your futures broker. If you have been sitting on the sidelines because you were not sure whether prediction markets were legal in the U.S., the answer on Kalshi specifically is unambiguous: yes.
