Our Top-Rated Prediction Market Sites in 2026
The best IPO prediction market sites
If you’re eager to get started, here’s a head-to-head comparison of the top prediction market sites for IPO trading based on the features that matter most for predicting upcoming IPOs:
| Prediction market | US Access | IPO markets you will find | Trading costs | Best for |
|---|---|---|---|---|
| Polymarket | CFTC-regulated US app via QCX, available in 40+ states | IPO date ladders, valuations, largest IPO of the year | Varies by market | Widest range of private company markets |
| Kalshi | CFTC-designated contract market | Which companies announce an IPO this year, head-to-head IPO races | Per-contract fee that varies with price | Rule-driven IPO event contracts |
| Plus500 | Plus500 Futures app, Kalshi-powered | Kalshi economic and financial event contracts | $0.01 commission per contract | Low-cost access for futures traders |
Polymarket – The deepest IPO market menu
- Numerous markets on sports, crypto, the economy, and politics
- Regulated by the CFTC
- Multiple rewards for existing traders
- Crypto payments only
If you’re looking for a trusted IPO prediction market, Polymarket is our top pick because of the wide variety of private company markets it offers.
Even though this selection is a relatively new addition, it already offers dedicated markets covering private company milestones, IPO timelines, and secondary market activity, all backed by Nasdaq Private Market data.
On Polymarket, you’ll find ladder-style markets, from buzzworthy SpaceX IPO prediction market such as “SpaceX IPO by ____?” to contracts on the year’s largest IPO and which companies will list before 2027.
As for access, the Polymarket app is available in the United States through CFTC regulation, which runs on the licensed QCX exchange and can be accessed in more than 36 states.
The app is easy to navigate and offers real-time pricing and liquidity updates that make it easy to track market movements as they happen. Just keep in mind that the market selection for IPO trading can vary by location, so you may have to check what’s listed for you.
Kalshi – Best for regulated IPO event contracts
- Broad range of markets
- 24/7 live chat support
- Huge reputation
- Native mobile app
- Transaction fees
As the first CFTC-regulated exchange built specifically for event contracts, you’d expect Kalshi to host IPO coverage worth trading. While that’s obviously true, its rules-first approach is why we see it as an excellent destination for purchasing IPO contracts.
Kalshi’s flagship IPO market is one that is focused on asking straightforward questions like which companies will officially announce an IPO this year.
But unlike how it works as one of the best US debt default prediction market sites, Kalshi’s settlement for IPO is clearly defined. Contracts resolve when the SEC declares an S-1 registration effective, the IPO is priced, or an exchange assigns a ticker.
You’ll also find popular head-to-head contracts, such as whether OpenAI or Anthropic goes public first, which have already drawn millions of dollars in volume.
Even better, the fact that Kalshi offers its economics prediction markets just alongside IPO event contracts makes it easy for traders to gauge market sentiment and see the bigger picture before making any decision.
Plus500 – Low-cost access to Kalshi markets
- Exclusive welcome offer
- Dedicated mobile apps
- Responsive customer support
- No existing prediction trader promos
While Plus500 is reputable for its futures trading, its launch of prediction markets in February 2026 with Kalshi-powered event contracts has made exceptional statements and is the reason why it’s on our radar.
If you already trade futures on Plus500, getting started shouldn’t be an issue. You can trade event contracts from the same account without opening a separate account, and you still get access to a market that’s largely comparable to Kalshi’s regulated options.
However, what this Kalshi-engineered prediction market stands out for is its affordable access to buying and selling “Yes” or “No” contracts. This is also why it makes headlines as one of the best fed rate prediction market sites.
Plus500 clears the contracts itself and charges a small $0.01 per contract in commission, putting it among the most cost-effective regulated prediction markets today.

How IPO prediction markets work
If you’re new to prediction markets, it’s natural to wonder how IPO trading works and what it takes to get started.
For starters, an IPO prediction market trading is all about buying “Yes” or “No” contracts on whether a privately held company will reach a specific IPO milestone.
In other words, it turns questions about future listings of these companies into a tradable contract, such as “Will Company X IPO by December 31?”
To take a position, you’ll either buy a Yes or No contract, typically priced between $0.01 and $0.99. That price reflects the market’s view of the likelihood that the event will happen. The higher the price, the higher the perceived probability.
To show you how this works in real time, take, for instance, you’ve got a Yes contract at $0.40. That is a suggestion that the market is pricing roughly a 40% chance the listing happens on time.
If you buy the contract at $0.40 and the company goes public before the deadline, the contract settles at $1, giving you a return of $0.60 before any fees. If the IPO doesn’t happen, the contract settles at $0, and you lose the $0.40 you paid to enter the trade.
As for the contracts, you’ll commonly come across three main types, including:
- Binary (Yes/No): A straightforward market that asks a question such as, “Will Anthropic IPO before December 1?”
- Categorical: These markets focus on multiple possible outcomes. For example, “In which month will Company X IPO?” Here, each month has its own contract, and only the correct outcome settles at $1.
- Scalar: These contracts are centered around a numerical range, such as a company’s first-day closing market cap or IPO valuation.
Just as important as the contract type is the market’s resolution criteria and the rules that follow it. That’s because those rules are the deciding factor in when and how a contract settles.
Unlike the more direct approach with crypto launch prediction markets, some IPO markets settle on a public S-1 filing, while others wait for an IPO pricing announcement or the first day of trading. That’s why it’s worth reading the fine print before you trade.
