About 15 years ago, it was unrealistic to suggest to a Wallstreet risk manager that in 2025 serious money would flow into the markets through predictions. The idea of saying this candidate is going to win and making money out of your prediction was non existent back then. Yet today, prediction markets or as I would like to call it glorified gambling, are suddenly one  of the hottest corners of finance. They started as a weird crypto side quest but now they are a big sector. Kalshi, a CFTC-regulated prediction platform has just raised $1 billion at an $11 billion valuation according to CoinDesk. Polymarket, Kalshi’s crypto native rival has been circling $1 billion valuation on a roughly $200 million round lead by Founders Fund. Polymarket, was very popular dring the U.S. election season that they saw about $8 billion in bets and outcliicked FanDuel as well as DraftKings on web traffic.

Now, the real plot twist is that Intercontinental Exchange (ICE), the parent company of the New York Stock Exchange plans to invest up to $2 billion in Polymarket at $9 billion valuation. When the same people who run the NYSE decide they like your on-chain bettign app, know that something big is happenning.

So, what is Polymarket?

To make it easy, we can take Polymarket as a stock market for questions. And the role of the user is to bet and predict on the answers to these questions. Each market is usually a binary contract that settles at either 0 or 1 based on wha happens in the real world. This system and structure of prediction markets is almost similar to binary options trading. This means that a correct prediction will give you a reward according to the preset prediction price, but if your answer is wrong, you get nothing and lose your capital.

This matters because it turns opinions into a tradable asset class. Instead of shouting on social media that there is no way inflation omes out above 3% this month, just predict and put money on it if you are confident. If you are correct, you win the price, but if you lose, you also lose your stake. And the good thing about this is that the price updates are in real time as new information comes in.

Why a giant like ICE cares

So, why is a big gun like ICE cozying up to a crypto prediction or betting market that used to only be known by degenerates  on Crypto Twitter? Well, the first thing is that to ICE, Polymarket is not a casino but more like a derivatives exchange with extra spice. After all Polymarket has standardized contracts on real world events, fees pr trade and risk management as well as clearing infrastructure. CoinDesk notes that Polymarket has already processed around $8 billion in bets around the U.S. election cycle. They also logged around 15.9 million site visits in May 2025, topping major sportsbooks like FanDuel and DraftKings. This shows that prediction markets are not just an experiment anymore, but a mainstay in this sector.

The other thing is that every prediction marrket is a also a firehorse of probability data. This means that they can gather data on sentiments about odds in elections, market expectations for CPI, rate cuts or crypto prices and sentiment on sports, tech launches or geopolitical shocks. For data hungry institutions like ICE, prediction markets data streams can power new indexes based on event probabilities, structured products and derivatives tied to those odds as well as analytic packages that can be sold to funds, corporations or risk desks. Yahoo’s report on ICE-Polymarket deal explicitly highlights ICE’s plan to distribute Polymarket’s event-based data globally as part of the partnership.

Finally, once Polymarket is under a clear U.S. regulatory, ICE can, in theory, pipe thosemarkets into brokers it already touches. However, this is already the thing as in November 2025, the CFTC granted Polymarket an Amended Order of Designation. This cleared PolyMarket as a fully regulated U.S. event contract exchange. U.S. users will nowbe able to access contracts via the futures commission merchants and traditional brokerages, putting polymarket on a similar footing to other federally supervised exchanges. 

Moving from Grey Zone to Grown-Up market

For many years, U.S. prediction markets lived inlegal purgatory somewhere between online gambling  site and derivative exchange. Under the U.S law, event-based contracts like these generally fall under the CFTC, not state gaming boards. In 2025, the CFTC did not just sign off on Polymarket’s amended designation but it also announced a dedicated prediction markets round table to rethink how to regulate sports and other event contracts. Regulators are effectively admitting tht this is no longer a play gamebut it has become part of financial infrastructure. 

Now, once you see that prediction markets are regulated derivative venues rather than shady offshore casinos, ICE’s interests will stop looking wild and start looking boringly logical.

Final thoughts and conclusion

A TradFI heavyweight backing Polymarket is a giant greenlight on the idea that blockchain based markets can price real world events efficiently. This means that users must expect easier access via mainstream brokers, deepr liquidity and tighter spreads, more serious products and also heavier KYC, more surveillance, and fewer degen edge case markets. So, days of anonymously making crypto based predictions are over, only the real stuff remains!
