Owing to the latest funding round, Kalshi has now reached an estimated valuation of $5bn, the company said in a press release shared on its website. The round was co-led by Andreessen Horowitz (a16z) and Sequoia Capital, with a "significant participation" from Paradigm.
Kalshi’s fresh funding comes at a time of global expansion
Among the prominent bakers were companies such as Spark Capital, CapitalG, General Catalyst, and Coinbase Ventures. This announcement comes concomitantly with another important piece of news, with Kalshi now expanding to 140 countries globally and attacking Polymarket's dominance in the sector.
Kalshi recently raised $300M+ at $5B from Sequoia, a16z, Paradigm and others.

Since then, we've grown over 3x, hit $50B of annualized volume, and became the largest prediction market in the world.
And today…Kalshi goes global.

The company appears to be on the same rapid valuation trajectory as its globe-trotting rival, with Kalshi now becoming an international company as well. According to Kalshi, the expansion will create a "single, unified liquidity pool for prediction markets." In a statement, the company clarified:
"Prediction markets have always had worldwide relevance. Events don’t stop at borders, and now, neither does trading on them. Whether it’s elections, central bank decisions, sports, or climate, users across continents can trade directly on the outcomes that shape their world."
Kalshi is set to close the gap between itself and Polymarket
Kalshi has boasted important milestones, the company said, with its trading volume growing by a factor of 200 in the past year alone, along with a 20-fold increase in its user base. According to the company, Kalshi already controls 60% of the global prediction markets, edging out Polymarket’s proclaimed dominance.
The company will leverage the success of the latest funding round to work on important milestones. Kalshi will continue to invest in its teams, integrate with more brokerages and institutions, and launch new market types and structures, among other ambitious long-term strategic goals.
The latest investment round is a far cry from the NYSE owner’s $2bn check signed to Polymarket; however, Kalshi seems to be fast closing the gap between the two.
