【CryptoPush】Forecast Trading Platform Kalshi just announced its 2025 report card, with all metrics hitting record highs, and the growth rate can be described as “outrageous.”

In terms of nominal trading volume, the total annual transaction amount reached $23.8 billion, a staggering 1108% increase compared to last year, nearly 12 times higher. Just in December, $6.38 billion was recorded, setting a monthly record; in the 4th week, a weekly high of $1.7 billion was achieved; and on December 21st, a single-day transaction of $381.7 million broke the daily record.

The number of trades is equally astonishing. Throughout the year, there were 97 million transactions, soaring 1680% year-over-year, equivalent to 17.8 times last year’s total. In December alone, there were 27.67 million trades; in the 4th week, 7.6 million; and on December 21st, 1.5 million, with each figure continuously breaking records.

However, the growth rate of open interest is relatively “moderate.” The total open interest for the year reached $225 million, an increase of 169% (about 2.7 times), but a peak of $533 million was already reached on March 9th. Looking at the timeline, the highest monthly open interest was in February, and the weekly open interest in the first week of March was also just over $500 million.

From the perspective of total contracts, a total of 23.8 billion contracts were traded throughout the year, with growth multiples consistent with the trading volume (1108%). The last few weeks of December were especially hot: 6.38 billion contracts monthly, 1.7 billion weekly, and 382 million on a single day. The data reveals a signal — the prediction trading market experienced exponential expansion last year, especially with a noticeable increase in trading enthusiasm at the end of the year.

23.8 billion USD? The growth rate is really crazy. The prediction trading sector is finally getting noticed. A 12x increase is outrageous, but Kalshi's data indeed shows something unusual. Just want to ask if this growth rate can be sustained, and after reaching the peak, will it fall back down?

Damn, Kalshi, these data are really outrageous, $23.8 billion with a 12x growth? Why didn't I catch this wave? Kalshi is crazy, $380 million in a single day on December 21st, how many people are going all-in... 1108% growth... brothers, is this the future of predictive trading? The monthly doubling pace makes my trading platform look weak. Wait, why did it suddenly surge at the end of the month? Did something happen? Short sellers must be feeling really uncomfortable seeing this data haha. 97 million trades, Kalshi has really become a hit. If this growth rate continues for another year, it could break through $100 billion? Feels like I missed another opportunity...

Wow, this growth is really insane… 12 times? It feels like the entire prediction market has been awakened. This data, starting with 233, is it already this fierce? Kalshi really caught the wave this time, but those who turn quickly make money fast and those who turn quickly also lose money fast… Have you guys followed in? $23.8 billion… Just thinking about how bleak 2024 will be makes you realize how fierce this explosion is. It feels like the next big breakout in the prediction market is here, but don’t be fooled by these numbers. High trading volume = more opportunities, but there are also many pitfalls.

Damn, are these growth numbers really not calculated incorrectly? 1108%? Feels like Kalshi is about to take off --- Was there a big event on December 21? 380 million in a single day—how is that so crazy? --- 97 million trades for the whole year... averaging 2.66 million trades a day? How many people are playing? --- A 12-fold increase is truly outrageous, just want to know how much of this trading volume is genuine demand --- Finally, a platform is able to surge in prediction trading, much stronger than the previous few --- That December wave was really incredible, it feels like the entire prediction trading sector was ignited by it --- If this data is real, Kalshi might become the biggest dark horse in the crypto space this year --- 1680% year-over-year growth... this speed is unmatched on any platform, need to see if it can be sustained afterward

Wow, are these growth numbers real? 12 times? It feels a bit unbelievable. Kalshi, what was it discovered by? Why did it suddenly explode? 23.8 billion... This prediction trading platform has really risen, redefining my understanding. Wait, is this trading volume or actual transactions? The numbers seem a bit inflated. After the US election, the traffic is also insane. Can this thing really be played?
