Kalshi vs PredictIt: Which Is Better in 2026?

Kalshi and PredictIt are both US-regulated prediction markets, but they represent different eras of the industry. PredictIt launched in 2014 as an academic research project with a limited CFTC no-action letter, while Kalshi launched in 2020 as a fully designated CFTC contract market built for scale. The gap between them has only widened since.

Key Differences

The core difference is that Kalshi was built as a modern financial exchange, while PredictIt was built as an academic experiment that happened to attract real traders.

Kalshi operates as a CFTC-designated contract market in New York, offering contracts across sports, politics, economics, weather, finance, and culture. In 2025 it processed $43.1 billion in volume and captured roughly 66% of the US market share. No position limits, plus a public API for algorithmic trading.

PredictIt is operated by Victoria University of Wellington through Aristotle International under a CFTC no-action letter. It focuses exclusively on political markets with a hard cap of $3,500 per trader per market. Around 400,000 registered users, a fraction of Kalshi's volume. The $3,500 cap alone disqualifies PredictIt for any serious trader.

Fee Comparison

This is where the comparison becomes stark:

• Kalshi charges no commissions on trades and a $0.01 settlement fee per contract when a market resolves. No deposit fees, no withdrawal fees.
• PredictIt charges a 10% fee on all profits and a 5% fee on all withdrawals. These fees stack — if you make $100 in profit, you lose $10 to the profit fee, and then lose another $4.50 when you withdraw the remaining $90.

To illustrate: on a $1,000 investment earning $500 profit, Kalshi costs roughly $5 in settlement fees. PredictIt costs $50 in profit fees plus $72.50 in withdrawal fees — a $117.50 difference that scales with your winnings. PredictIt's fee structure is by far the most expensive of any US prediction market.

Market Selection

Kalshi covers a broad range of categories:

• Sports (NFL, NBA, MLB, NHL, and more)
• Politics and elections
• Economics (inflation, jobs reports, Fed decisions)
• Weather (temperature, hurricanes, snowfall)
• Finance (stock prices, crypto, IPOs)
• Culture and entertainment

PredictIt covers:

• US politics and elections

That is it. PredictIt is a politics-only platform. If you want to trade on anything else — sports, economics, weather — PredictIt cannot help you. PredictIt historically had an edge in niche political races, but Kalshi has expanded its political coverage significantly and now matches or exceeds PredictIt in most categories.

User Experience

Kalshi offers a modern web platform and native mobile app. The interface is clean and functional, with real-time order books, market depth charts, and detailed historical data. Deposits via bank transfer or debit card are straightforward, and withdrawals typically process in 1-3 business days. Kalshi also provides a public API for algorithmic trading.

PredictIt has a dated web interface that has not been meaningfully updated in years. There is no native mobile app — you trade through the mobile browser. Deposits are made via credit or debit card, and withdrawals take 5-10 business days. Kalshi feels like a modern fintech product; PredictIt feels like a web application built for a university research project.

Regulation and Trust

Kalshi holds full CFTC designation as a contract market (DCM). This is the highest level of US regulatory approval for a derivatives exchange. Customer funds are held in segregated accounts, and Kalshi operates under direct CFTC oversight.

PredictIt operates under a CFTC no-action letter issued to Victoria University of Wellington, with Aristotle International serving as the US operator. A no-action letter is not the same as a full DCM designation — it means the CFTC has agreed not to pursue enforcement action, but it does not provide the same level of regulatory protection. PredictIt's no-action letter was actually revoked by the CFTC in 2023, though the platform has continued operating through legal proceedings.

For regulatory certainty, Kalshi is the clear winner. PredictIt's regulatory status has been in question for years.

Who Should Choose Kalshi

Choose Kalshi if you want a modern, low-fee prediction market with broad market coverage and no position limits. Kalshi is the right platform for casual traders who want an easy onboarding experience, serious traders who want API access, and everyone in between. With $43.1 billion in volume and the strongest regulatory standing in the industry, Kalshi is the default choice for US prediction market trading in 2026.

Who Should Choose PredictIt

PredictIt may still appeal to a narrow audience: political junkies in states where Kalshi is not yet available who want to make small wagers on elections. PredictIt's availability in all 50 states is its one remaining advantage. However, between the 10% profit fee, 5% withdrawal fee, $3,500 position cap, politics-only focus, and dated interface, most traders will find Kalshi to be the superior option by a wide margin.
