Wellington Management and other institutional investors are in advanced discussions to anchor the fundraise for the prediction markets operator, Kalshi. Sequoia Capital is in talks to lead the round along with Wellington, while Tiger Global and Dragoneer are also among the potential participants, Reuters reported Tuesday. The deal is expected to close in the coming weeks based on terms cited by people familiar with the matter.

The funding would value Kalshi at roughly $40 billion, an 82% jump from the $22 billion valuation it held during a $1 billion raise in May. An SEC filing in August indicated the company raised $1.12 billion between April and August. While Kalshi has held early discussions about a potential IPO in the coming years, competing platform Polymarket is also separately seeking about $1 billion in new capital.
