TL;DR:
- Kalshi reached a valuation of $22,000 million ($22 billion) following a $1,000 million ($1 billion) funding round in May 2026.
- The prediction platform recorded a notional volume of $29,800 million ($29.8 billion) during the month of April 2026.
- Meta is internally developing a competing application called Arena that will use play money managed by artificial intelligence.
Mark Zuckerberg, chief executive officer of Meta, held business talks to acquire the prediction market platform Kalshi before ordering the development of the tech firm’s own application. According to a report published this Monday by NPR, the confidential meetings were held during the year 2025.
According to the report, the meetings took place directly between Zuckerberg and the forecasting platform’s co-founder, Tarek Mansour, during a period of high user traction. Data from close sources suggested that negotiations halted before Facebook’s parent company presented a formal buyout offer.
Strategic shift and the development of Arena
Apparently, the talks ceased due to conflicting stances. On one hand, some reports indicated that the prediction firm’s management rejected the sale, while other sources pointed out that Meta’s regulatory team considered the sector’s legal challenges as an excessive risk.
The financial forecasting sector faces a complex legal environment. In the United States, states like Minnesota have classified the operation of these platforms as a felony, and the Department of Justice maintains open investigations into alleged insider trading at competing firms.
Following the cessation of the buyout negotiations, Zuckerberg instructed his engineering team to design an independent product internally dubbed Arena. Technical data from the project reveals that the platform will not use real money, a decision through which Meta seeks to bypass classification as a gambling product.
The software infrastructure will operate through artificial intelligence systems developed by the corporation. According to the preliminary technical design, these automated algorithms will be responsible for both formulating current affairs questionnaires and validating the final resolutions of the markets.
Financial consolidation in prediction markets
The platform’s commercial dynamism continued to rise despite the cancellation of the sale. The forecasting firm closed a $1 billion Series F funding round led by investment firm Coatue, with participation from venture capital funds such as Sequoia and Andreessen Horowitz.
The company’s operational metrics show accelerated growth in institutional volume. At the close of the first half of the year, the firm reported annualized revenues exceeding $1.5 billion, driven by an 800% increase in institutional transactions over the last semester.
The evolution of the sector’s financial volume reflects the growing interest of financial market participants. According to analytical records from Dune Analytics, platforms in the sector processed more than $63 billion in total trading volume throughout the year 2025.
The next operational milestone for Meta’s network will consist of closed testing for the Arena application. This technical deployment will determine the viability of the play money model against the traditional financial markets of the ecosystem.
