I just noticed an interesting development in the prediction markets sector. Kalshi and Polymarket, the two leading platforms in this sector, are apparently in funding talks and are aiming for valuations of around $20 billion each. This would mean their values have roughly doubled compared to the valuations at the end of last year.

For context: Kalshi was last valued at $11 billion, and Polymarket at $9 billion. The platform by Tarek Mansour and Luana Lopes Lara, founded in 2018 and operating under the oversight of the Commodity Futures Trading Commission, raised $1 billion in December. Polymarket, founded in 2020 by Shayne Coplan, was able to attract Intercontinental Exchange as an investor in October, which was willing to invest up to $2 billion.

What impresses me most: The open interest on these platforms is remarkable. Kalshi's is over $400 million, and Polymarket's is $360 million. The weekly trading volume is also impressive – about $1.9 billion on Polymarket and $1.87 billion on Kalshi in the last 6 hours measured. These numbers show how quickly this market is growing.

The idea behind prediction markets is actually quite elegant: users can trade contracts linked to real events – whether politics, sports, elections, or other areas. Essentially, they speculate on the outcome of these events and monetize their knowledge about world affairs.

What’s interesting is that this trend is no longer limited to crypto-native platforms. Coinbase and Robinhood have already launched their own prediction markets. And now, big Wall Street names are also getting involved – Nasdaq and Cboe are considering offering binary bets on traditional markets, similar to prediction markets.

The discussions are still in an early stage, but if these valuations materialize, it would be a strong signal for the sector. Some analysts expect prediction market companies to reach an annual revenue of $10 billion by 2030. This indicates that we are only at the beginning.
