There are several binary event betting / prediction market apps that work in a similar spirit to Kalshi, but they differ a lot in regulation, geography, and whether they use real money or play money.

Quick Scoop: What Are the Binary Betting Apps Like Kalshi?

Kalshi itself is a CFTC‑regulated US exchange where you trade “yes/no” contracts on events (inflation numbers, election outcomes, Fed decisions, etc.), much like binary options but focused on real‑world data releases and events.

Around it, an ecosystem of prediction markets and event‑contract platforms has grown, especially by 2026, with options for both US and non‑US users.

1. The closest “event contract” cousins

These platforms feel the most similar in concept: trading on whether a specific event will happen.

  • Kalshi (baseline)
    • Real‑money, CFTC‑regulated prediction market in the US.
* Focuses on macro, politics, financial, and economic releases (CPI, Fed decisions, elections).

* Contracts typically settle at 0 or 1 dollar depending on outcome, like binary bets.
  • Polymarket
    • Crypto‑based prediction market (USDC on Polygon), widely considered the biggest by volume and liquidity.
* Broad range of markets: politics, crypto events, tech, culture.

* Officially blocks US users and operates offshore with no US regulatory protection, which is a key difference from Kalshi’s CFTC framework.
  • PolyGram (newer non‑US alternative)
    • Built specifically as a Kalshi‑style event‑contract platform for European/global users.
* Uses binary event contract mechanics similar to Kalshi (politics, economics, sports) but without requiring a US bank account.

* Aims to combine Kalshi’s structure with Polymarket‑style depth and variety.
  • FanDuel Predicts / other sportsbook “prediction” products
    • Some US sportsbooks now add simple event markets (e.g., “Will X team make playoffs?”) under a betting framework, which can feel Kalshi‑like but are still sportsbooks, not full exchanges.
* Typically regulated as sports betting, not as a dedicated prediction exchange.

These are the closest if your mental model of “apps like Kalshi” is “I want to buy and sell binary event contracts, not traditional bets.”

2. Political and academic prediction markets

These lean heavily into political outcomes and academic research, but still give you tradeable event contracts.

  • PredictIt
    • Long‑running academic prediction market backed by Victoria University of Wellington.
* Focused mostly on US politics: elections, control of Congress, party primaries, etc.

* Operates under a limited CFTC “no‑action” framework for research, with low position limits (e.g., around $850 per market) and noticeable fees (trading and withdrawals).

* US users can participate legally, but it feels smaller‑scale and less polished than Kalshi, with narrower markets and lower liquidity.
  • Iowa Electronic Markets (IEM)
    • Academic prediction market run by the University of Iowa since the late 1980s.
* Tiny scale compared to modern platforms, mainly used for research on forecasting and market efficiency.

* Not a mainstream retail app, but historically one of the first “Kalshi‑like” ideas.

If you specifically care about elections and political forecasting, these are the closest analogues.

3. Forecasting platforms (no real money, but similar questions)

These feel Kalshi‑like in terms of questions asked (“Will X happen by Y date?”) but don’t use real cash.

  • Metaculus
    • Forecasting community where you earn reputation points, not money.
* Heavy focus on long‑term and complex questions: AI development milestones, climate outcomes, policy decisions, scientific breakthroughs.

* Great for sharpening your probabilistic thinking but doesn’t scratch the real‑money trading itch.
  • Manifold Markets
    • Play‑money prediction market where users create markets on anything: politics, tech, pop culture, niche topics.
* Uses its own play currency; more “fun/experimental” with a strong online community and social features.

* You can’t earn real money, but it mirrors the trade mechanics of a prediction market and is popular in online forums.

These are useful if you like the structure of binary event prediction but don’t want legal/regulatory entanglements or financial risk.

4. Betting exchanges and sports‑centric platforms

Here you get something structurally similar (back/lay, peer‑to‑peer, prices representing probabilities), but the focus is more sports and conventional betting.

  • Betfair Exchange
    • One of the largest betting exchanges globally, particularly in the UK/EU.
* Core use is sports, but it offers markets on politics and other events too.

* Technically not a dedicated prediction market like Kalshi, but the exchange mechanics and probability pricing feel similar.
  • Smarkets
    • UK‑licensed betting exchange that includes political and event markets alongside sports.
* More betting‑exchange than pure prediction market, but the line between “binary event betting” and “prediction market” gets blurry here.

If your main interest is sports plus some politics/event markets, these can substitute for “binary betting on events,” although the regulatory category is sports betting rather than CFTC‑style event contracts.

5. Crypto / Web3 prediction market ecosystems

There’s now an entire Web3 segment of “apps like Kalshi,” focused on decentralized prediction markets.

  • Polymarket (again, as the main one)
    • Decentralized, runs on Polygon, uses USDC, and hosts wide event markets.
* High liquidity and tight spreads on major topics; many serious event traders use it alongside Kalshi (if they’re non‑US or accept risk).
  • Augur
    • Early Ethereum‑based prediction market protocol that is now largely inactive and overshadowed by newer platforms.
* Fully decentralized and censorship‑resistant but struggles with liquidity and user experience.
  • Other Web3 alternatives lists
    • Web3 directories now list dozens of Kalshi‑like prediction dapps (50+ alternatives as of 2026), showing just how crowded the crypto prediction space has become.

This segment targets users comfortable with crypto custody, smart contracts, and offshore legal frameworks.

6. Newer “apps like Kalshi” round‑ups

Several 2026 reviews now track and compare the landscape:

  • Lists from outlets like SI, Covers, TheLines, and niche blogs highlight 6–9 top Kalshi alternatives across regulated platforms, crypto markets, and free forecasting tools.
  • Common names across these lists include Kalshi, Polymarket, PredictIt, Metaculus, Manifold, Betfair, and sometimes Robinhood event contracts or FanDuel Predicts.
  • They typically sort platforms by “best for US users,” “best for non‑US users,” “best for practice,” and “best for sports,” reflecting how no single app fully replaces Kalshi for every user type.

7. Legal and practical landscape (2026)

Regulation and geography matter more here than in normal betting apps.

  • Kalshi remains the primary CFTC‑regulated, real‑money prediction market available to US retail users.
  • Polymarket has stronger liquidity and broader markets but is officially closed to US users and lacks US regulatory protection, which is a major trade‑off.
  • PredictIt is legal in the US but has strict position limits and higher fees, making it feel more “academic niche” than a full trading platform.
  • Metaculus and Manifold avoid money entirely, sidestepping gambling law complexities and making them accessible almost everywhere, but they’re not “betting apps” in the traditional sense.
  • Regional exchanges like Betfair and Smarkets serve UK/EU users under gambling regulations rather than event‑contract rules.

In other words, the “binary betting apps like Kalshi” scene in 2026 is less about one perfect clone and more about choosing between regulatory safety, liquidity, market breadth, and whether you want real money or practice environments.

9. Forum / discussion flavor

In online forums and prediction communities, discussion around “apps like Kalshi” in 2026 often sounds like:

“If you’re in the US and care about doing this cleanly, Kalshi is still the go‑to; everything else is either crypto risk, academic scale, or play money.”

“Outside the US, Polymarket is the main arena, but newer platforms like PolyGram try to give you Kalshi‑style event contracts without needing a US setup.”

“For pure forecasting skill, Metaculus and Manifold are amazing, but don’t expect a paycheck — they’re more for calibration than cash.”

This reflects that the “best” alternative really depends on where you live and whether your priority is regulation, liquidity, market breadth, or learning.

10. If you’re just starting out

If you’re curious about binary event trading like Kalshi and want a simple path:
