Kalshi Raises $1 Billion as Prediction Markets Hit $2.2 Billion Weekly
Kalshi has raised $1 billion in new funding at an $11 billion valuation, per TechCrunch. The spherical, led by returning traders Sequoia and CapitalG, comes lower than two months after the prediction market operator closed a $300 million spherical at a $5 billion valuation.
The fundraise arrives alongside a notable knowledge level: Kalshi now generates extra weekly buying and selling quantity than Polymarket, regardless of having constructed its person base nearly solely with American merchants.
Geographic context issues
Polymarket was barred from serving US residents from 2022 till September 2025. During that three-year interval, the platform constructed its liquidity with merchants from Europe, Asia, and elsewhere.
Kalshi, in contrast, operated as a US-only change till October 10, when it announced expansion to 140 international locations. That growth is six weeks previous, and per Sportico, worldwide entry stays inconsistent. Traders in India, Brazil, Nigeria, and Finland have posted on Discord and X that they can’t register accounts.
It’s truthful to imagine Kalshi’s present quantity relies on US customers.
This reframes the comparability in two methods. First, the US alone is producing extra prediction market exercise than the remainder of the world mixed—a testomony to American urge for food for occasion buying and selling. Second, Kalshi captured that market whereas Polymarket was locked out of it.
Per-market liquidity nonetheless favors Polymarket
The mixture numbers obscure a big hole in particular person market depth. Polymarket’s highest-volume contract—Super Bowl Champion 2026—has generated $160.7 million in buying and selling quantity over the previous 30 days. Kalshi’s main market, the Federal Reserve’s December 2025 rate of interest resolution, has produced $3.5 million.
Where equivalent occasions commerce on each platforms, the unfold is substantial. The December Fed resolution reveals $120.9 million in quantity on Polymarket versus $3.5 million on Kalshi. The 2028 Democratic Presidential Nominee market reveals $104.3 million on Polymarket versus $1 million on Kalshi.
This hole possible displays Polymarket’s three-year head begin constructing liquidity in high-profile markets. It may additionally mirror person composition: Polymarket’s crypto-native viewers—customers depositing USDC and connecting wallets—skews towards bigger place sizes. Kalshi’s fiat on-ramps and Robinhood integration (25-35% of volume) appeal to a unique profile.
Valuation context
Kalshi’s $11 billion valuation arrives as the corporate studies $50 billion in annualized buying and selling quantity, per the New York Times—a greater than one-hundred-fold enhance from roughly $300 million the prior yr.
Polymarket, which received CFTC approval to serve US customers in September, is reportedly in discussions to boost extra capital at a $12 billion to $15 billion valuation, per Bloomberg.
The US market will resolve the class
Both platforms now have US regulatory authorization and world ambitions. Kalshi secured the fitting to serve American customers after prevailing in litigation towards the CFTC final yr, although it continues to face challenges from state regulators who contend its contracts represent unlawful playing.
The knowledge above suggests American merchants generate extra prediction market quantity than the remainder of the world mixed. Whoever wins the US market will possible outline the class.
Kalshi is betting that regulatory legitimacy and conventional finance integrations—Robinhood, financial institution accounts, potential brokerage partnerships—will pull mainstream customers away from crypto rails. Polymarket is betting that liquidity begets liquidity: merchants go the place the depth is, and three years of gathered market-making in high-profile contracts creates a moat that fiat on-ramps alone can not breach.
Both will likely be examined over the subsequent yr as the platforms compete for a similar customers for the primary time.
