# The New Prediction Markets of 2026: Rothera, Robinhood & the Full Landscape

> The 2026 prediction-market landscape has new players — Rothera (Susquehanna x Robinhood), Polymarket's regulated US path, Kalshi, and sports-first Opinion. A complete, current map of who's who and who fits which trader.

**The prediction-market map changed in 2026.** A record World Cup summer pulled in new audiences, a brand-new institutional entrant appeared, and Polymarket opened a regulated US path. If your mental model of the space is still "Polymarket vs Kalshi," this is the current picture — including the players most comparison articles haven't caught up with yet.

## Quick Answer

<Note>
  The 2026 prediction-market landscape now has more than two names that matter:

  * **Kalshi** — CFTC-regulated US exchange; cleared `$30B+` in June 2026 ([CNBC](https://www.cnbc.com/2026/07/04/2026-fifa-world-cup-boosts-prediction-market-volumes.html)).
  * **Polymarket** — the volume leader on politics/global markets; now with a **regulated US path via its QCX / QC Clearing acquisition** ([Yahoo Finance](https://finance.yahoo.com/markets/crypto/articles/prediction-markets-news-kalshi-polymarket-161958621.html)).
  * **Rothera** — a **new Susquehanna × Robinhood joint venture** that launched June 2026 and already holds \~7% of US prediction-market volume ([Yahoo Finance](https://finance.yahoo.com/markets/crypto/articles/prediction-markets-news-kalshi-polymarket-161958621.html)).
  * **Opinion** — the **sports / esports / World Cup specialist** with web2-style onboarding and low sports-category fees.
  * **Manifold, PredictIt** — niche (play-money; US-politics-capped).

  **The theme of 2026: the field is crowding, fees are compressing, and sports is the new center of gravity.** This guide maps who fits which trader. Live board: [`app.opinion.trade/world-cup`](https://app.opinion.trade/world-cup).

## What's New in 2026

Three shifts separate the 2026 landscape from the "Polymarket vs Kalshi" era:

1. **Institutional entry.** Rothera — backed by trading giant Susquehanna and brokerage Robinhood — went from zero to \~7% of US prediction-market volume in its first month ([Yahoo Finance](https://finance.yahoo.com/markets/crypto/articles/prediction-markets-news-kalshi-polymarket-161958621.html)). When a firm like Susquehanna enters, spreads tighten and the category matures.
2. **Regulated US paths multiply.** Polymarket acquired **QCX and QC Clearing** to operate a regulated US venue, joining Kalshi's existing CFTC-designated status ([Yahoo Finance](https://finance.yahoo.com/markets/crypto/articles/prediction-markets-news-kalshi-polymarket-161958621.html)). The regulatory picture is firming up under the [CFTC event-contract framework](https://www.cftc.gov/IndustryOversight/EventContracts/index.htm).
3. **Sports became the main event.** The World Cup pushed sports past politics as the most-traded category ([CNBC](https://www.cnbc.com/2026/07/04/2026-fifa-world-cup-boosts-prediction-market-volumes.html)) — which reshuffles which platform is "best" depending on what you actually trade.

## Who Fits Which Trader

* **You want the deepest politics/macro liquidity** → **Polymarket**. Still the volume leader on flagship global markets, now with a regulated US route.
* **You require CFTC regulation and fiat rails** → **Kalshi**. The established US-regulated exchange.
* **You came for the World Cup, sports, or esports** → **Opinion**. Built for exactly this category, with the lowest-friction onboarding (email + card, no wallet required) and low sports-category fees ([fees doc](https://docs.opinion.trade/trade-on-opinion.trade/fees)). See [What Is Opinion?](/learn/what-is-opinion-prediction-market).
* **You already live inside Robinhood** → **Rothera** may surface where you trade equities, though it's the newest and least battle-tested.
* **You want to learn risk-free** → **Manifold** (play money) before trading real capital.

## Why "More Players" Is Good for You

A crowded field is a trader's friend:

* **Fees compress.** New entrants competing for flow push effective costs down across the board. On the sports category, Opinion already sits at the low end with a `0–1%` topic-rate cap and `$0.25` minimum.
* **Spreads tighten.** Institutional market-makers like Susquehanna narrow bid-ask, so you keep more of each trade.
* **Coverage widens.** More venues means more markets — and specialists like Opinion go deep on categories (sports, esports) the generalists treat as an afterthought.

The flip side, per [Yahoo Finance](https://finance.yahoo.com/markets/crypto/articles/polymarket-kalshi-volumes-hit-150b-145540046.html): **surveillance and regulatory scrutiny are tightening** as the category scales. Availability, eligibility, and rules vary by jurisdiction — check yours before trading.

## Where Opinion Fits

In a landscape splitting between politics-first incumbents and institutional newcomers, **Opinion's wedge is category specialization**: the deepest sports, esports, and 2026 World Cup catalog, the fastest onboarding for web2 users, and among the lowest effective sports-category fees. If you arrived through the World Cup and want to keep trading sports and esports, that's the fit. Live board: [`app.opinion.trade/world-cup`](https://app.opinion.trade/world-cup).

## What to Watch

* **Does Rothera stick?** Zero to 7% in a month is dramatic — watch whether Robinhood distribution keeps it growing or whether it fades post-World-Cup.
* **Regulated-path competition.** With Polymarket now pursuing a regulated US venue alongside Kalshi, the "which one is legal in the US" answer is changing — re-check before assuming.
* **Fee compression.** More competitors should keep pushing effective fees down. Compare current rates before you commit size.
