Kalshi and Polymarket Begin Talks for $20 Billion Capital Rounds

Key Points

• Kalshi and Polymarket explore fundraising rounds that may value each company near twenty billion dollars, almost double the levels reported near the end of 2025.
• Prediction markets now draw heavy user activity, while combined monthly trading volume reached about eighteen point three billion dollars across both platforms.
• These funding discussions arrive during rising regulatory pressure and political debate around contracts linked to geopolitical and sensitive events.

Kalshi and Polymarket began early discussions with investors about fundraising rounds that could place each company at a valuation of around twenty billion dollars. People aware of the situation explain that these conversations stay at an early stage and no investment agreement exists at this moment. Since negotiations still move forward uncertainty remains and talks may close without a signed deal or a finished funding round. If investors finally accept proposed valuation levels both companies would roughly double figures recorded close to the end of 2025. Sources added that representatives from both platforms recently spoke with several investment funds about participation in possible fundraising rounds. Kalshi completed its most recent capital raise during December when the company secured one billion dollars in funding at an eleven billion dollars valuation.

That funding round received main support from Sequoia and CapitalG while Andreessen Horowitz Paradigm and other investors also joined. At the same time Polymarket reached a valuation of nearly nine billion dollars in October after Intercontinental Exchange agreed to invest up to two billion dollars. Intercontinental Exchange also operates the New York Stock Exchange through its parent company structure. If those fundraising rounds close near proposed levels both prediction market companies would experience a major jump from earlier valuations. Kalshi operates within the United States with approval from the Commodity Futures Trading Commission which permits regulated prediction market trading activity. The company started operations in 2018 after founders Tarek Mansour and Luana Lopes Lara created a platform to establish an event trading marketplace. Polymarket began service in 2020 when founder Shayne Coplan launched the platform and restricted access for users located in the United States.

Instead the company expanded operations across international markets while it waited for regulatory clarity inside the domestic market. After Polymarket obtained clearance from the Commodity Futures Trading Commission in November platform started opening a domestic application for waitlisted United States users during December. Because of that progress the company now plans to launch a regulated United States version of the trading platform later this year. Prediction markets allow participants to trade contracts connected directly with real-world events including sports results elections political outcomes and other developments. Through this mechanism traders purchase or sell contracts depending on their expectations regarding future outcomes. These markets therefore allow participants to transform knowledge or expectations about world events into financial positions which pay when outcomes occur. Growth across the sector encouraged both companies to discuss higher valuation targets with potential investors.

Data from The Block indicates combined monthly trading volume across Kalshi and Polymarket reached about eighteen point three billion dollars during February. Only months earlier both platforms together produced less than two billion dollars in monthly trading volume around August 2025. This increase shows trading activity expanded fast as more traders entered prediction markets tied to world developments. Kalshi also reported revenue growth during the same period of market expansion. The platform recently moved beyond one billion dollars annualised revenue run rate as trading activity increased across the exchange. Some individuals familiar with company finances believe the real figure may approach one point five billion dollars per year. Since September exchange has maintained higher monthly trading volume compared with Polymarket. Much trading activity came from sports contracts which users traded actively on the platform.

Kalshi Passes $1 Billion Super Bowl Trading Volume

Kalshi recorded more than one billion dollars in trading volume during Super Bowl Sunday according to chief executive Tarek Mansour which indicates demand for event trading. Because of that activity platform holds a large amount of capital locked inside markets many times. Current data shows open interest on Kalshi now stands above four hundred million dollars across active contracts. At the same moment Polymarket also keeps major open interest with around three hundred sixty million dollars connected to contracts. Despite the dominance of these companies other prediction market platforms remain smaller. For example third market Opinion now records open interest near thirty-six million dollars. Weekly trading numbers also reveal a gap between leading platforms and the rest of the sector. During the previous week Polymarket achieved about one point nine billion dollars weekly notional trading volume. This figure represents the underlying value of all prediction contracts traded on the platform during that period.

Meanwhile Kalshi showed comparable activity with around one point eight seven billion dollars weekly notional trading volume. Opinion generated roughly one hundred fifty million dollars in weekly trading volume during the same period. However this result marked a drop from more than one point two billion dollars weekly trading volume recorded earlier before the token launch. Because of that difference most trading activity still remains concentrated on the two largest prediction market platforms. Technology firms financial institutions and cryptocurrency companies now watch prediction markets with growing interest. Companies including Coinbase Gemini Crypto.com DraftKings and Robinhood have already entered the sector or revealed plans for prediction market products. Financial exchanges also started reviewing the industry as attention toward event trading expands across markets. Wall Street institutions recently examined trading structures resembling prediction market systems. Because interest rises both Nasdaq and Cboe Global Markets now consider launching yes or no binary contracts.

These contracts allow traders to place wagers in the direction of financial markets. Such a structure mirrors prediction market design where contract resolution depends on outcome occurrence. Although the sector expands quickly and draws investor attention fundraising talks now occur during a period of political and regulatory pressure. Lawmakers in the United States recently introduced legislation which may restrict the types of contracts prediction platforms can list. Representatives Blake Moore and Salud Carbajal proposed a bill seeking to block contracts linked to wars and sports events. The proposal followed weeks of debate connected with contracts tied to geopolitical developments. During that time on-chain analytics firm Bubblemaps detected six cryptocurrency wallets which earned nearly one million dollars combined. Those traders placed bets on a potential military strike by the United States against Iran. Trades appeared hours before airstrikes began on February twenty eight raising questions about possible prior knowledge.

Because of concerns lawmakers in the United States Senate are now reviewing risks connected with prediction markets. Senator Chris Murphy prepares legislation banning contracts allowing speculation on decisions made by the United States government. Murphy states that individuals connected with the decision process may receive early information about policy or military plans and use it for profit.

Debate Intensifies After Kalshi Contract Linked to Iranian Leader

Another dispute appeared when Kalshi’s contract allowed traders to bet on whether Ali Khamenei would leave office before March one. Soon after attention increased Khamenei died in joint strikes by the United States and Israel on March one which triggered criticism. Due to this event critics argued the market functioned like a proxy death market despite the contractual death carveout clause used by the company. At the same time Kalshi also faced a legal dispute tied directly to the same prediction contract. The company received an accusation claiming failure to pay nearly fifty-four million dollars to traders predicting Khamenei’s departure before March one. A class action lawsuit filed in court argues that Kalshi refused to apply the death indemnity provision after the leader’s death. The complaint claims the company avoided the use in order to avoid payment to traders holding winning contracts.

Meanwhile Polymarket also faced criticism concerning the prediction markets offered on the platform. The company later removed the contract linked to the detonation of a nuclear weapon after backlash from observers and regulators. Alongside those disputes both platforms face enforcement action started by several state gaming regulators. Regulators argue sports related prediction contracts offered by platforms resemble gambling products without a licence. However federal regulators hold a different view about sector oversight. The Commodity Futures Trading Commission states it holds exclusive authority over prediction market contracts within the United States. This stance created a policy dispute between federal authorities and state regulators about control of the prediction market industry. Beyond regulatory pressure strategic investors now examine a deeper role in the prediction market sector.

Brokerage firm Jump Trading currently evaluates the purchase of a stake in both Kalshi and Polymarket. Through this arrangement the firm would also supply liquidity to markets operating on these platforms. Such support may allow traders to execute orders while improving price discovery across prediction contracts. Funding concentration around these two companies shows how competition now forms inside the prediction market industry. Most venture capital entering the sector flows mainly toward Kalshi and Polymarket rather than spreading across smaller platforms. Because of this situation investors increasingly treat the industry as a contest between two dominant companies controlling trading activity. If either company raises capital at a twenty billion dollar valuation the resulting value would exceed the market capitalisation of DraftKings.

Such a valuation would also position the company near Flutter Entertainment which operates the FanDuel sports betting platform. This comparison highlights debate regarding whether prediction markets operate as financial infrastructure or resemble online gambling activity.
