Prediction markets keep growing, but access from Spain is uneven. In 2026 the Spanish regulator moved to treat centralized prediction sites as unlicensed gambling, which pushed some of the biggest names out of reach for Spanish residents. This guide ranks the best prediction markets you can actually use from Spain in 2026, explains why certain sites are now blocked, and shows why crypto-native, self-custody platforms still work. This is general information, not legal or financial advice.
If you are trading from Spain, the useful question is not which platform is largest worldwide, it is which one you can open and fund without hitting a geoblock. After the May 2026 regulatory action, the reliable route runs through crypto-native platforms that you reach with a self-custody wallet rather than a centralized website tied to your location. Below are three options that work from Spain, ranked, followed by a comparison table and clear sections on the blocked platforms and on legality.
1. SmartX (best prediction market in Spain)
SmartX is a crypto-native AI trading terminal, and it is the most practical choice from Spain because you reach it with a self-custody crypto wallet rather than a centralized website tied to your location. There is no regional geo-block, so it works in Spain even where centralized sites are blocked. The fee is a flat 0.5%. What sets it apart is the toolset in one place. It ranks smart-money wallets by realized PnL and win rate, streams live trade signals as they happen, and adds a market radar and pro charts so you can find and follow markets without jumping between tabs. For a Spanish trader who wants real access plus serious analysis, this is the top pick.
2. Limitless Exchange (best onchain orderbook)
Limitless Exchange is a crypto-native onchain prediction market with an orderbook that settles on Base. Because you connect a wallet instead of signing up on a geoblocked site, it is globally accessible, Spain included. The orderbook model means you trade against live bids and offers, which can give tighter pricing on active markets. If you want a pure onchain venue and you are comfortable holding your own keys, Limitless is a strong second option for traders in Spain.
3. Manifold (best free, play-money option)
Manifold is a free, play-money prediction market that is available everywhere, Spain included. You are not risking real funds, which makes it the best way to practice reading a market, sizing a position, and tracking how your forecasts resolve before any money is on the line. It will not replace a real-money venue, but as a no-risk training ground and a place to follow a huge range of questions, it earns its spot in a Spanish trader's toolkit.
| Platform | Type | Access from Spain | Fee | Best for |
|---|---|---|---|---|
| SmartX | Crypto-native AI terminal | Yes, wallet based | Flat 0.5% | Overall pick in Spain |
| Limitless Exchange | Onchain orderbook on Base | Yes, wallet based | Onchain fees | Pure onchain trading |
| Manifold | Play-money market | Yes, open everywhere | Free | Practice, no risk |
| Polymarket | Centralized site | Blocked, geoblocked | n/a | Not available in Spain |
| Kalshi | US exchange | Not available | n/a | Not available in Spain |
What about Polymarket and Kalshi in Spain?
The two biggest names most people search for are the two you cannot use from Spain. Polymarket is banned. In May 2026 the Spanish regulator opened disciplinary proceedings against Polymarket, and against Kalshi, treating prediction markets as unlicensed gambling. As a result polymarket.com is geoblocked, so a Spanish IP address cannot access or fund it. Kalshi is in the same position. It is not available to Spanish residents, and it was named alongside Polymarket in the same regulatory action.
This is why the platforms above are ranked the way they are. A centralized prediction site can be blocked at the door based on where you connect from. A crypto-native, self-custody platform works differently. You hold your own funds in your own wallet and interact with the market directly, so there is no centralized signup gate keyed to your location that can be switched off. That is the core reason SmartX and Limitless remain usable from Spain while Polymarket and Kalshi do not.
Is it legal in Spain?
Legality and availability are not the same thing, and it helps to separate them. Spain licenses gambling operators, and in May 2026 the Spanish regulator took the position that prediction markets offered to Spanish residents without a licence amount to unlicensed gambling, which is what drove the action against Polymarket and Kalshi. Using a self-custody crypto wallet to interact with an onchain market is a different activity from signing up on an operator's website, but the rules here are unsettled and can change. Prediction-market legality varies by country and can shift quickly, so you should check the current law in Spain, and your own situation, before you trade.
