- Wellington Management and Sequoia Capital are reportedly in discussions to lead the investment, joined potentially by Dragoneer and Tiger Global.
- This proposed valuation represents an 82% increase over the $22 billion figure from just four months ago.
- Company executives have discussed the possibility of pursuing a public market debut in the future.
- Competitor Polymarket is pursuing approximately $1 billion in funding through separate negotiations.
Prediction market operator Kalshi is negotiating to secure nearly $1 billion in fresh capital. Sources say the funding round would assign the company a valuation in the neighborhood of $40 billion.
Reuters broke the story on September 29, drawing on information from individuals with knowledge of the discussions. The financing has yet to reach completion and the company has made no public statement confirming the round.
Wellington Management and current backer Sequoia Capital are said to be in conversations about taking the lead investor roles. Dragoneer Investment Group and Tiger Global Management have been mentioned as potential additional participants.
When contacted by Reuters, both Kalshi and Tiger Global opted not to provide comments. Dragoneer, Wellington, and Sequoia similarly did not reply to inquiries.
Sources speaking to Reuters indicated the transaction could finalize within weeks. However, the specific terms remain subject to modification prior to any final agreement.
The timing represents a rapid ascent for the platform. In May, Kalshi completed a $1 billion Series F financing at a $22 billion price point, with Coatue serving as lead investor.
The May funding round drew participation from numerous prominent firms including Andreessen Horowitz, Sequoia, Paradigm, IVP, ARK Invest, and Morgan Stanley. Kalshi disclosed at that time that institutional trading volume had surged 800% across a six-month span.
During the same timeframe, annualized trading volume climbed from $52 billion to reach $178 billion. This explosive expansion seems to be fueling renewed investor appetite for additional funding.
The $22 billion valuation had itself doubled from an $11 billion assessment assigned only a few months prior. Moving to $40 billion would constitute roughly an 82% gain since the May round.
Speculation about a potential $40 billion valuation emerged initially in June. The Financial Times published reports at that point suggesting a deal might conclude during the third quarter.
The Rising Appeal of Prediction Market Platforms
Prediction market platforms enable participants to purchase and sell contracts linked to actual events. Categories span elections, economic indicators, and sporting competitions.
Throughout 2026, trading volumes in this sector experienced rapid expansion. Kalshi captured a substantial portion of this increased activity.
According to sector statistics, prediction markets processed $50.6 billion in trading volume during July alone. Kalshi was responsible for $37.7 billion of that figure.
Polymarket’s combined domestic and international operations generated $12.9 billion during that same period. Kalshi has simultaneously moved into additional financial instruments, including cryptocurrency derivatives.
The platform operates under a distinct regulatory framework compared to typical wagering services. In November 2020, the Commodity Futures Trading Commission granted Kalshi designation as a contract market.
Public Listing Discussions and Continuing Legal Challenges
Company leadership has engaged in preliminary conversations regarding a potential public offering. CEO Tarek Mansour has referenced the possibility of going public, though no formal documentation has been submitted.
Documentation filed with the Securities and Exchange Commission on August 25 revealed that Kalshi registered an exempt securities offering. This filing does not provide specifics regarding the newly reported $1 billion fundraising effort.
Legal uncertainties persist for Kalshi across multiple state jurisdictions. Judicial decisions have varied on whether certain contracts offered by the platform constitute gambling under state statutes.
A federal appellate court issued a ruling on September 25 addressing disputes originating in Tennessee and Ohio. Additional courts have arrived at divergent interpretations in other proceedings.
Regulatory agencies continue examining prediction markets connected to equity performance. Both the CFTC and SEC are conducting assessments of how current regulatory frameworks apply to these emerging contract types.
Primary rival Polymarket is pursuing comparable fundraising objectives. Reuters has reported that Polymarket is in discussions for approximately $1 billion in new capital, building on earlier reports suggesting a potential $20 billion valuation.
