Doc: Kalshi's and Polymarket's CEOs are investing in an upcoming VC, led by two early Kalshi staff, that's raising up to $35M to back prediction market startups

Fortune Ben Weiss

Context & Ripple Effects

This report extends the prior account of a VC fund backed by the two platform CEOs and led by former early Kalshi staff. It moves the story from the platforms’ own fundraising to capital formation around new companies in their category.

The fund emerges as Kalshi and Polymarket were reportedly seeking roughly $20B valuations in separate fundraising discussions, following earlier large financings for both companies. That makes a dedicated seed vehicle a notable sign of ecosystem-building rather than a standalone platform bet.

First-order effects

  • The proposed fund gains recognizable strategic backers in Kalshi’s and Polymarket’s CEOs, while two early Kalshi employees take on the role of investing in prediction-market startups.
  • Founders building prediction-market businesses would have a specialized potential source of early-stage capital, subject to the fund completing its raise.

Second-order effects

  • Specialist funding can increase competition for talent, product ideas, and distribution partnerships around the two incumbent platforms, while giving incumbents closer visibility into emerging entrants.
  • A category-specific fund may make it easier for adjacent investors to evaluate prediction-market startups, but it also concentrates early ecosystem influence among people tied to a leading platform.

Third-order effects

  • If more capital and operator-led funds follow, prediction markets could evolve from a pair of high-profile platforms into a broader startup stack of market operators and supporting services.
  • The pattern points toward platformization: leading companies using their networks and capital to shape the startup ecosystem that develops around their market category.

The trend: Prediction markets are shifting from platform-level fundraising toward an operator-financed startup ecosystem.

    Can confirm. I'm told this fund will target all kinds of ancillary businesses, from market makers to companies working on AI infrastructure for platforms and prediction-market ‘native media’ (which could mean many things). The two founders both used to work at Kalshi.

    I have a feeling I'm going to hate 100% of the companies backed by this new fund.
