What types of CA predictions markets can you trade?

When we speak about the best California prediction markets, we mean trades that are specific to the Golden State. When you think about it, there’s a surprising number of markets that CA residents might be interested in. From our experience, this can include markets like:

For example, similar to the best Florida prediction markets, a good chunk of CA markets relate to the vast number of pro sports teams the State has. This includes:

At the top sites, you can find loads of predictions for these teams including individual game markets, and futures markets for things like end of season awards and trophy winners.

Additionally, you’ll often find weather markets relating to rain and daily temperatures. These are usually for major cities in the State like Los Angeles, San Diego, San Jose, and San Francisco.

Lastly, predictions for politics and elections in California are hugely popular. For instance, at the time we wrote this guide on the best California prediction markets, the US Midterms were ongoing. As a result, there were a huge range of markets for the different elections, processes, and seats that were open in the Golden State.

Pros and cons of CA prediction markets

Ventajas e inconvenientes
  • Hugely popular
  • Loads of sports teams
  • Great trade volume
  • Solid political offering
  • Only concentrates on larger cities

What to look for when choosing prediction market apps in California?

Similar to sites for the best Washington State prediction markets, there are operators who are better for CA prediction markets. Firstly, there are three main factors you should consider including regulatory oversight, the CA predictions they offer, and their trading fees. After that, there’s other considerations like usability, banking, and trade liquidity:

CFTC regulatory oversight

The regulatory scene for prediction markets is continually evolving. However, it’s advisable to only use operators that have regulatory oversight from the Commodity Futures Trading Commission. This is the main body responsible for regulating things like futures and trade derivatives.

CA prediction markets

Obviously the main emphasis here is California prediction markets. Because of this, you should first browse the P2P prediction exchange to see what California-specific markets they have. Do they feature CA pro sports markets? What about Californian elections and political markets? Some sites do have a better offering for CA-based markets than others.

Low trading fees

You should not have to pay huge fees for the best California prediction markets. Instead, we expect CA P2P prediction exchanges to offer low trading fees that are at least in line with industry averages. For context, from the extensive testing and research we’ve done, we believe the max fee per trade should be $0.02. Anything over this and things start to get tricky when you’re trading predictions with contracts at 80c and higher.

Desktop and mobile usability

This depends on whether you want to trade via your computer or mobile. Either way, it’s advisable to look at the usability of a site and how it works. Ideally, the prediction markets should be easily accessible and logically organized. We love to see major categories, and then sub categories within those so you can easily find what you want.

Also, page speeds should be fast, and the trade contract prices should update instantly. For mobile accessibility, we want to see downloadable apps. For instance, Kalshi, Polymarket, and Plus500 all have downloadable mobile apps from both the App Store and Play Store.

Banking setup

A site could have all the US midterm prediction markets in the world and everything you want, but if you can’t deposit money then it’s useless. This is why you need to look at their banking arrangement. What payment methods can you use for deposits and withdrawals? Do they have any minimum deposit and withdrawal limits? What about things like payment fees? We feel that the best sites charge no fees, offer fast withdrawal processing, and support multiple common payment methods.

Trading liquidity

Lastly, you need to look at the order books and trade liquidity. Sure, a site might feature the best California prediction markets, but if no one is placing orders for them, you’re screwed! Sites like Kalshi, Polymarket, and Plus500 had healthy order books and your orders generally get matched instantly, or within a short amount of time.

You’ll notice that popular prediction markets, for example, can often have tens of millions in trading volume. This means that you should be able to move your trade contracts easier, and get out of bad trades if needed.

Our top three picks for the best prediction market sites in California

Similar to our guide on are prediction markets legal, we believe specific operators are better suited for certain types of prediction trading. Indeed, for the best California prediction markets, we’ve chosen these three exchanges:

Polymarket – great for daily CA temperature predictions

Polymarket: Pros and Cons
  • Numerous markets on sports, crypto, the economy, and politics
  • Regulated by the CFTC
  • Multiple rewards for existing traders
  • Crypto payments only
Visit Polymarket

We rate Polymarket as one of the best temperature prediction market sites, especially for California. It has a dedicated weather category, and an epic feature for this section is the “Globe”. Click this, and you get a 3D model of Planet Earth, that shows all the different cities it supports temperature and rain prediction markets for. We often see daily temperature highs for cities like Los Angeles, but there’s also rainfall, snow, drought, and natural disaster prediction markets.

Polymarket is also a good option for usability. Golden State residents can use the desktop website which is especially smooth. We love how the different prediction categories are laid out here, and the features like the Globe that they offer. Alternatively, there’s also two downloadable apps for Android and iOS devices.

You shouldn’t have any issue making deposits and withdrawals at Polymarket either. It supports both crypto and fiat payments, and has quick withdrawal processing speeds. Users should be able to make payments using methods like Apple Pay, Google Pay, Bitcoin, Tron, PayPal, and Debit Card. Finally, you can check out the banners to see what current welcome bonus Polymarket offers. It sometimes has an offer where you can trade X to get X in bonus funds.

Kalshi – a massive collection of LA sports team predictions

Kalshi: Pros & Cons
  • Broad range of markets
  • Asistencia por chat en directo 24 horas al día, 7 días a la semana
  • Huge reputation
  • Native mobile app

Visit Kalshi

If you are a diehard supporter of one of the many California pro sports teams then Kalshi is a superb option. Alongside Polymarket, this is arguably the top option for California sports prediction markets, with a main concentration on LA sports teams. For example, it has markets for all of the Los Angeles Lakers regular season NBA games. Plus, you can trade futures markets such as whether they will make the Playoffs or Western Conference Finals.

Aside from the NBA, California sports fans can also check out the Kalshi markets for the NFL, MLB, NHL, MLS, and WNBA. Plus, they are one of the few US prediction market exchanges that have live sports predictions. This can make things especially interesting when you are watching games live and fancy making a few cheeky trades at the same time.

Kalshi also is the top option for market share, and as a result, trade volume. We’ve never had any issue getting our orders filled here for the best California prediction markets and they also have things like trading incentive programs. These help keep the order book healthy and make sure that trades are not sat on the order books for too long.

Plus500 – superb range of California election and political predictions

Plus500: Pros and Cons
  • Exclusive welcome offer
  • Aplicaciones móviles específicas
  • Responsive customer support
  • No existing prediction trader promos
Visit Plus 500

Plus500 excels with its political and electoral prediction markets. For instance, when we made this article, they had an entire section dedicated to the US Midterms. This included markets for all the relevant California elections and outcomes for the House and Senate seats, plus things like Governors. Not only that, but they have overall markets for the Republican and Democratic parties.

Outside of politics, other categories that Plus500 supports includes financials, entertainment, crypto, companies, commodities, climate, sports, and science and tech. We like that it has a dedicated commodities section for those interested in precious metals and oil and gas. You’ve got a load of markets for daily Copper, Gold, and Silver prices, for instance.

There should also be a welcome bonus for new Plus500 customers running now where you can get a $20 trading bonus. All you have to do to get this is click our banners, sign up, and make $10 in trades. Lastly, we think this is one of the better sites for trading fees. It charges a flat $0.01 per contract, and you should never pay more than $0.02 per contract either way.
