Kalshi vs PredictIt (2026): The Comparison
The Short Answer
Kalshi is a CFTC-designated contract market. PredictIt is a not-for-profit research project that says in its own terms it is not regulated by the CFTC. Kalshi lists sports, crypto, weather, culture, politics and now perpetual futures, and publishes documented REST, WebSocket and FIX APIs; PredictIt runs roughly eighty political markets, caps you at $3,500 per contract, takes a reported 10% of profits plus 5% to withdraw, and its terms forbid automated access. Pick Kalshi for breadth, size and tooling. Pick PredictIt if you specifically want its political order books and can live inside the cap.
Most kalshi vs predictit comparisons online are describing a venue that no longer exists. They tell you PredictIt caps you at $850, that only 5,000 traders can enter a market, that Victoria University of Wellington runs it, and that the CFTC shut it down in early 2023. Every one of those was true once. None of them is true now.
The harder problem is that these two are not really the same category of thing, so "which is better" collapses on contact. One is a venture-backed exchange valued at $22 billion in its most recent funding round at the time of writing, whose activity is overwhelmingly sports. The other is an explicitly non-commercial experiment in political forecasting that spent three years in federal court defending its right to keep operating, and won.
Key Takeaways
- PredictIt is alive and trading in August 2026. It won its case against the CFTC in July 2025, the $850 position cap became $3,500, and the 5,000-trader-per-market limit was cancelled.
- The legal footing is genuinely different. Kalshi has been a designated contract market since November 2020. PredictIt operates under a no-action letter, CFTC Letter 14-130 of October 2014 as amended in July 2025, and states plainly that it is not CFTC-regulated.
- Scope is not close. PredictIt lists politics only, in six categories. Kalshi lists sports (the large majority of its activity), crypto, weather, entertainment and perpetual futures.
Is PredictIt Still Around? Yes, and It Won
The most common search on this topic assumes a funeral. There wasn't one. As of August 2026 predictit.org is up, markets are open across Elections, President, Congress, State and Local, World and Weekly, and the site's own news page carries articles published through June 2026.
The confusion is understandable. The CFTC revoked PredictIt's no-action letter on 4 August 2022 and ordered positions liquidated by 15 February 2023. That headline is where a great deal of internet coverage froze. What happened next: PredictIt and Aristotle sued in the Western District of Texas, the Fifth Circuit granted an injunction on 26 January 2023, and in July 2025 PredictIt won the case. The relaunch that followed raised the per-contract cap to $3,500 and removed the trader cap entirely. The $3,500 is not a number PredictIt picked. The CFTC letter that amended its relief pegs the per-contract investment limit to the individual campaign contribution limit under the Federal Election Campaign Act, which the FEC adjusts for inflation every two years, so the cap moves when that limit moves.
One more correction while we are here: the operator is Prediction Market Research Consortium, a not-for-profit, with Aristotle International as service provider. Articles naming a New Zealand university are describing an older arrangement.
Kalshi vs PredictIt on Scope: Eighty Political Markets Against an Everything Exchange
PredictIt's sitemap lists exactly six categories and all six are political. "World" means foreign elections. "Weekly" means Trump approval, the generic congressional ballot, presidential posting volume. There is no sports, no crypto, no weather, no culture. A single snapshot of PredictIt's public market-data endpoint in August 2026 returned something in the region of eighty open markets, which is an order of magnitude rather than an official count, but it is the right order of magnitude.
Kalshi does not publish a total market count either, and we are not going to invent one. What is documented is the shape: dedicated help-centre coverage for weather, crypto, Spotify, Netflix and app-store markets, multi-leg sports contracts visible in the live API, and a seventeen-article collection on perpetual futures, a product line PredictIt has no analogue for at all. Sports is reported at more than 90% of site activity and about 89% of Kalshi's 2025 fee revenue. If your mental model is "Kalshi is the economics and politics exchange," that model is about three years out of date.
For political traders specifically, this cuts both ways. PredictIt's narrowness means its order books concentrate the political audience rather than diluting it across ten thousand sports lines. Whether that produces better prices is an empirical question, and the honest answer is that it varies by market and by how close the event is. A price in cents reads as a market-implied probability in percent on either venue, and thin books distort that reading in both directions.
Limits, Fees and What Each One Costs You
Here is the side-by-side. One caveat before you read it: PredictIt's 10% fee on profits is documented in coverage going back to 2019 and still reported by third-party reviews in 2026, but the live site no longer restates the percentage anywhere we could find. The terms set fees by reference to a "How to Trade" page that does not itself carry the figure. That some trading fee is charged is not in doubt, though: the terms incorporate a fee structure by reference, and the CFTC's 2025 amending letter contemplates the operator using fees generated by trading to run the market. Budget for the 10% until PredictIt says otherwise, and read its terms page before you fund anything.
| Item | Kalshi | PredictIt |
|---|---|---|
| Legal status | CFTC-designated exchange, Nov 2020 | 2014 no-action letter, amended July 2025 |
| Scope | Sports, crypto, weather, culture, politics, perps | Politics only, six categories |
| Position cap | Per-market limits in contract rules, no account-wide cap | $3,500 per contract |
| Optional cap | User-set monthly funding cap | None |
| Deposit fee | ACH free, debit up to 2% | None |
| Withdrawal fee | ACH free | 5% plus any method fees, 30-day hold after first deposit |
| Trading fee | 0.07 x C x p x (1-p) taker, standard rate | 10% on profits, reported but not restated on site |
| Inactivity fee | None | $2 per month after 12 months |
| API | REST, WebSocket, FIX, published specs | Read-only endpoint, automation banned |
Two lines deserve expanding. Kalshi's taker fee rounds up to the next cent per order and peaks at 1.75 cents per contract at a price of 50 cents, shrinking toward both tails; the mechanics are in our Kalshi fees breakdown, and the authoritative version is Kalshi's own fee schedule, which is revised often enough that you should open it before sizing an order. Some series run off the standard coefficient entirely. And the only cap Kalshi asks you to set is a personalized monthly funding cap, which is a responsible-trading tool rather than a restriction; its binding limits are per-market position limits published in each contract's rules. PredictIt's $3,500 is a different animal: mandatory, pegged to the no-action letter, and identical for everyone.
The API Question, Where the Gap Is Widest
PredictIt does expose a public market-data endpoint at /api/marketdata/all/. It responds without authentication and returns live prices. It is genuinely useful for research.
It is not a trading API, and calling it one gets people into trouble. There is no developer programme, no authentication, no order placement, and PredictIt's prohibited-conduct clause explicitly bars using "any manual or automated software, devices or other processes to engage in automated trading, to scrape or extract data from the Website." Read that clause before you point a cron job at it. Kalshi, by contrast, publishes OpenAPI and AsyncAPI specifications, supports FIX, manages API keys, documents rate-limit tiers and runs a demo environment. If you are building anything, that is not a close call, and our Kalshi API guide is the place to start.
Legal Footing: One Exchange, One Letter, One Confusing Footnote
Kalshi's position is simple to state: designated contract market since 3 November 2020, regulated by the CFTC, currently fighting a long list of state gambling regulators (Massachusetts, Michigan, Nevada, Minnesota and others through 2026) over whether federal jurisdiction preempts them. Contested, but contested at the state level, with the CFTC on Kalshi's side of the argument.
PredictIt's is stranger. The site still cites a Division of Market Oversight no-action letter and still says it is "not regulated by" the CFTC. The relief itself is CFTC Letter 14-130 from October 2014, amended on 14 July 2025 by CFTC Letter 25-20, which transferred the market from Victoria University of Wellington to the Prediction Market Research Consortium, scrapped the 5,000-trader limit and pegged the investment cap to the FECA contribution limit. Meanwhile the CFTC's register shows a designated exchange called Aristotle Exchange DCM, Inc., designated 5 September 2025, from the same corporate family and the same city. Reporting ties that date to PredictIt winning approval to expand as a regulated exchange. Here is the part everyone gets wrong in one direction or the other: the designation order does not name PredictIt anywhere, and the consumer site you actually log into has not moved onto that exchange. It still cites the no-action letter, still disclaims regulation, still applies the $3,500 cap, and has published no launch announcement for a DCM. Whether the two entities formally connect is inferred, not documented. One thing the amending letter does settle: the relief was issued to the consortium and, by its own terms, does not travel to another entity through any future sale or transfer of operations.
PredictIt Alternatives and the Three-Way Comparison
Most people arriving at "predictit alternatives" want more headroom than $3,500, or markets outside politics, or an API they are allowed to use. Kalshi answers all three. Polymarket answers them differently: the global platform is crypto-collateralised and excludes US users, while Polymarket US is a separate CFTC-regulated exchange with its own accounts, rails and fee schedule. Never blur those two. Our Polymarket vs Kalshi comparison handles that pairing properly.
If you would rather not open an exchange account at all, Robinhood routes event contracts through KalshiEX, ForecastEx and Rothera, with no API and a price-scaled commission; see Kalshi vs Robinhood. Bear in mind how many event-contract exchanges have been designated since PredictIt's fight began; the CFTC's registry of trading organizations is where to count them yourself. That wave is the real reason PredictIt's posture now looks like a period piece rather than a template.
Frequently Asked Questions
Is PredictIt still around in 2026?
Yes. PredictIt is live and trading as of August 2026, with open markets across Elections, President, Congress, State and Local, World and Weekly, and editorial content published through June 2026. The shutdown headlines came from the CFTC's August 2022 revocation of its no-action letter, which ordered liquidation by February 2023. The Fifth Circuit enjoined that order in January 2023 and PredictIt won the case in July 2025.
What do Reddit threads get wrong about kalshi vs predictit?
Four things, repeatedly. The PredictIt position cap is $3,500 per contract, not $850. The 5,000-trader-per-market limit no longer exists; it was cancelled at the July 2025 relaunch. PredictIt is not shutting down. And the operator is Prediction Market Research Consortium with Aristotle International, not Victoria University of Wellington. Threads written before mid-2025 get at least one of these wrong, and usually all four.
Can I use Kalshi and PredictIt at the same time?
They are separate venues with separate accounts, separate funding and separate rules, so nothing stops you from holding positions on both. The practical friction is on the PredictIt side: a $10 minimum balance to trade, a $3,500 cap per contract, a 30-day hold on withdrawals after your first deposit, a reported 10% cut of profits, a 5% withdrawal fee, and a $2 monthly inactivity charge after twelve months without logging in with a positive cash balance. Moving money back and forth is not free.
How does kalshi vs predictit vs polymarket compare?
Kalshi is a CFTC-designated exchange with the broadest scope, including sports, crypto, weather and perpetual futures. Polymarket is two things: a crypto-collateralised global platform that excludes US users, and Polymarket US, a separately regulated exchange with its own fee schedule and USD rails. PredictIt is the outlier: political markets only, roughly eighty of them, run as a not-for-profit research project under a 2014 no-action letter amended in July 2025, with a mandatory $3,500 cap.
What are the best PredictIt alternatives?
It depends on what pushed you away. If it was the $3,500 cap, or the reported 10% profit fee stacked on top of the 5% withdrawal fee, Kalshi and Polymarket US are the obvious regulated options. If it was the political-only scope, Kalshi lists the widest range of categories. If it was the ban on automated access, Kalshi publishes documented REST, WebSocket and FIX APIs with a demo environment, and Polymarket has a public API too. Check eligibility in your state or country before comparing anything else.
Conclusion
Treat this less as a versus and more as a sorting question. If you want size, breadth, or anything programmatic, Kalshi is the only one of the two that is built for it. If you want PredictIt's political books specifically, they are still open, the caps are looser than they were for a decade, and the litigation risk that hung over the site is resolved; you are just trading inside a research project that reportedly takes 10% of your profits, charges 5% on the way out, and does not want your bot. What has not changed is that the same event can print different prices in different places, which is the whole reason Predictefy exists, and our guide to prediction market data sources is where to look next. None of this is financial, tax or legal advice, and fees and limits move, so confirm the current numbers on each venue's own terms page before you fund anything.
