ProphetX pulled it off. On June 11, 2026, the CFTC approved it as both a designated contract market and a clearinghouse, the first sports-native exchange in the country to hold both licenses. One week later, on June 18, ProphetX launched nationwide as a regulated real-money exchange, timed to the World Cup, live in 49 states (everywhere but Nevada).
The sweepstakes era is over. Prophet Points and Prophet Cash are gone. If you read anything describing ProphetX as a sweepstakes app with a pending application, it’s out of date, including our own earlier coverage. This is now a fight between two federally regulated exchanges, and that makes it one of the most interesting comparisons in the space.
Quick Verdict
Kalshi remains the pick for most traders. Five years of operating history, hundreds of markets across every category, the deepest liquidity in US prediction markets, and a $22 billion valuation behind it. But ProphetX is now the most credible sports-only alternative, full stop. Same regulatory tier as Kalshi, vertically integrated exchange and clearing, peer-to-peer pricing with no house margin, and a launch footprint of 49 states. Sports-only traders who want to set their own prices finally have a regulated home built specifically for them.
Snapshot
Regulatory structure: Both now hold DCM and DCO licenses. Kalshi since November 2020 (exchange) and August 2024 (clearing). ProphetX since June 11, 2026, both at once, roughly seven months after filing in November 2025.
Welcome bonus: Kalshi, trade $10 and get $10. ProphetX, trade $10 and get $20, credited win or lose, usable within 14 days.
States: Kalshi operates nationwide federally, with sports contracts blocked in Michigan and contested in New York. ProphetX runs in 49 states, all but Nevada.
Age: Kalshi is 18+. ProphetX requires 19+, and 21+ in some states.
Markets: Kalshi covers politics, sports, economics, crypto, weather, climate, culture. ProphetX is sports-only by design.
Trade structure: Kalshi runs a central order book with market and limit orders. ProphetX is peer-to-peer with users setting their own odds, plus a proprietary Request for Quote mechanism for pricing multi-leg combos.
Two Regulated Exchanges, Two Philosophies
The regulatory gap that used to define this comparison closed in June. Both platforms now trade, clear, and settle in-house under CFTC oversight, with customer funds under federal protection rules. ProphetX earned the distinction of being the first sports-native operation to do it, and it went from approval to nationwide launch in seven days, which tells you the product was sitting ready.
What’s left is a philosophical split. Kalshi built a general-purpose event exchange where sports became the biggest category. ProphetX built a sports exchange and refused to be anything else. No elections, no CPI prints, no hurricanes. That focus shows up in the product: deep coverage across US leagues plus international soccer, MMA, tennis, and golf, and mechanics designed for people who think in odds rather than contract prices.
The peer-to-peer model is the real differentiator. On ProphetX you can take an existing offer or post your own price and wait for another user to match it, Betfair-style. There’s no market maker you’re paying a spread to by default, and no house margin baked into the line. Kalshi’s limit orders get you close to the same economics, but the ProphetX interface is built around price-setting as the primary behavior, not the advanced feature.
The RFQ mechanism deserves its own sentence: it lets users request quotes on multi-leg sports combos, priced by the market rather than by a book’s parlay engine. Among regulated venues, nobody else has it.
On fees, Kalshi publishes everything: taker fees peaking at $1.75 per 100 contracts at 50 cents, makers at a quarter rate. ProphetX’s regulated product is weeks old and we haven’t seen a settled published schedule worth quoting yet; check the current terms in-app before sizing up. The no-house-margin structure is the point, but structure and final cost are different questions.
When to Pick Kalshi
You trade anything beyond sports. ProphetX will never list a Fed meeting.
You want five years of regulated track record instead of five weeks.
You want the deepest books in the category; new exchanges need time to build liquidity.
You’re 18 and ProphetX’s 19+ floor (21+ in some states) shuts you out.
You’re in Nevada. Neither platform is friendly territory, but ProphetX is fully out.

The trade-$10-get-$20 bonus doubles Kalshi’s offer and pays win or lose.
You want in early on the platform most likely to become the sports trader’s venue of record.

Both?
For sports traders, this is the strongest both-platforms case on this list. Two regulated venues pricing the same games independently means real line-shopping and occasional outright discrepancies. Thirty dollars in combined bonuses to start, and Kalshi covers every category ProphetX deliberately ignores. There’s no version of a serious sports trading setup in 2026 that shouldn’t at least watch both books.
Bottom Line
For a year we described ProphetX as a promising application. Now it’s the first sports-native regulated exchange in American history, live in 49 states, three weeks into its real life. That’s a bigger accomplishment than most of this industry’s press releases put together.
Kalshi is still the better platform for most people, on depth, breadth, and track record. But the sports-only trader finally has a real choice, and competition between two regulated exchanges is exactly what this market needed. Trade both books. Let them fight over your fees. Sign up for Kalshi, or sign up for ProphetX.
