Key Takeaway: Google Finance now integrates live prediction market data from Kalshi and Polymarket, marking mainstream adoption of blockchain-based forecasting.
Bridging Traditional Finance and Decentralized Markets
Google Finance has quietly expanded its market tracking capabilities by integrating real-time data from prediction markets Kalshi and Polymarket, marking a pivotal moment in the mainstream acceptance of decentralized forecasting platforms. This integration, announced on November 6, 2025, allows users to query future market events directly through Google’s search interface and view current probabilities alongside historical trends.
The feature rollout, occurring over the coming weeks starting with Labs users, enables individuals to ask questions in plain language such as “What will GDP growth be for 2025?” and receive market-based probability forecasts. This development represents Google’s first foray into event-based financial tracking and signals a significant shift in how traditional finance platforms are embracing crowd-sourced intelligence.
By surfacing prediction market data through Google Finance, these platforms are being normalized alongside conventional stock and commodity information, enabling mainstream investors to access sentiment indicators that often react more quickly than equities or bonds to political and macroeconomic signals. Google Finance users can now view live odds on major events including elections, inflation reports, crypto regulatory outcomes, and GDP growth forecasts, with current market probabilities displayed directly in the search box and charts showing how these chances fluctuate over time.
Understanding Kalshi and Polymarket
Kalshi: The Regulated Approach
Kalshi operates as a federally regulated prediction market under US Commodity Futures Trading Commission (CFTC) oversight, having received its Designated Contract Market license in November 2020. Founded in 2018 by MIT alumni Tarek Mansour and Luana Lopes Lara, the platform was born from their experiences as financial analysts navigating uncertainties like the Brexit referendum.
The platform enables users to trade binary options on yes-or-no questions about future events, with contract prices reflecting the market’s estimated probability of outcomes. Kalshi has expanded to serve users in over 140 countries and now holds more than 60% of global prediction market share.
Polymarket: The Decentralized Pioneer
Polymarket, founded in 2020 by Shayne Coplan, runs on blockchain infrastructure built on the Polygon network. Unlike Kalshi’s regulated model, Polymarket initially operated as a decentralized platform outside the traditional derivatives space. The platform previously faced CFTC enforcement action in January 2022, resulting in a $1.4 million penalty and a requirement to cease serving US users.
However, Polymarket’s regulatory landscape has dramatically improved in 2025. In July 2025, the platform acquired QCEX, a CFTC-regulated derivatives exchange, for $112 million. A September 2025 CFTC no-action relief letter provided Polymarket with a pathway to legally re-enter the US market, and the company recruited former CFTC chair J. Christopher Giancarlo to lead its advisory board.
Explosive Growth and Institutional Interest
Both prediction platforms have experienced explosive growth, attracting substantial institutional investment and achieving multi-billion dollar valuations. Polymarket has accumulated over $21 billion in cumulative trading volume since 2020, with September 2025 monthly volume reaching approximately $1.42 billion to $1.50 billion.
In October 2025, Intercontinental Exchange (ICE), owner of the New York Stock Exchange, announced plans to invest up to $2 billion in Polymarket at a pre-money valuation of approximately $8 billion to $9 billion. Bloomberg subsequently reported that Polymarket was in early talks with investors for new funding at a valuation between $12 billion and $15 billion.
Kalshi has demonstrated equally impressive growth metrics. The platform raised $185 million in June 2025 at a $2 billion valuation. Just three months later in October 2025, Kalshi announced a $300 million Series D funding round at a $5 billion valuation, co-led by Andreessen Horowitz and Sequoia Capital. Bloomberg reported that Kalshi was receiving additional funding offers at valuations exceeding $10 billion.
Regulatory Clarity and Market Implications
The integration of prediction market data into Google Finance arrives as US regulators continue debating how to classify event contracts. After successfully challenging the CFTC in court in 2024, Kalshi received authorization to list contracts related to the presidential race, opening doors for other companies to enter the prediction market space.
A November 2025 report from Bernstein suggests prediction markets may achieve wider mainstream adoption and emerge as a viable asset class. The industry is projected to expand from $23.70 billion in 2025 to $82.35 billion by 2030 at a compound annual growth rate of 28.3%.
This integration fundamentally demonstrates that prediction markets are transitioning from fringe betting platforms into broader information-driven trading venues, with greater regulatory clarity, institutional investment, and deepening integration with retail brokerages accelerating global liquidity and mainstream adoption.
