Points of Focus

• Kalshi raises $1 billion and reaches an $11 billion valuation.
• November sets a new record with $4.54 billion in trading.
• Google and Coinbase integrations help prediction markets reach a broader audience.

Kalshi has raised $1 billion in new funding, propelling the prediction market platform to a big $11 billion valuation. This update comes right after the company’s busiest month ever. It shows how quickly the prediction market space is growing as more users and large platforms join in.

The Series E round was led by Paradigm, with Sequoia, Andreessen Horowitz and ARK Invest also taking part.

CEO Tarek Mansour says the company wants to create a new way for people to understand information by turning real questions into markets that settle with clear results.

Kalshi raised $1B at an $11B valuation.

A decade ago, only a few thousand people knew what a prediction market was.

Eighteen months ago, most prediction markets were banned – until we overcame the government to set them free.

Kalshi plans to utilize the new funds to attract more brokerages to the platform, partner with news outlets, and expand the range of markets available to traders.

Kalshi trading volume hits new highs in November

Prediction markets saw strong activity in November 2025, as Kalshi recorded $4.54 billion in trading volume, its highest so far.

Trading on the platform has grown 1,000 percent since 2024 and now crosses over $1 billion every week. Kalshi also moved ahead of Polymarket, which saw $3.76 billion in November 2025.

This growth shows a change in how people are using these platforms. Many traders now use event markets as a quick way to understand public opinion on politics, sports, and major news. More integrations across the industry have also helped this rise.

Prediction markets gain momentum with major integrations

Google has started showing Kalshi and Polymarket odds in its search results as part of updates to Google Finance.

Coinbase is also working on a website linked to prediction markets, and early hints suggest Kalshi may be powering the product.

This progress has also helped Kalshi’s main competitor. Polymarket is said to be in talks for a new raise that may value it between $12 billion and $15 billion.

Kalshi’s fast growth, new partnerships, and strong funding show how prediction markets are moving into mainstream use as traders look for clearer signals in a very noisy news cycle.
