Kalshi launched a perpetual futures contract tied to its US 500 index, covering 500 of the largest U.S. companies, on Tuesday 6 October 2026, Reuters reported. The contract lets traders take long or short exposure without owning the underlying shares and follows an August 2026 regulatory filing for equity-index perpetuals. The launch opens a new product line for Kalshi in direct competition with traditional derivatives exchanges and crypto venues.

Kalshi is in advanced talks to raise about $1B from existing and new investors, including Tiger Global Management and Dragoneer Investment Group, at a valuation of about $40B, Reuters reported on Sept. 29, 2026, citing people familiar with the matter. The raise is expected to be finalized in the coming weeks and follows a $1B round in May at $22B. It would nearly double Kalshi's mark in about four months, resetting secondary pricing.

Weekly volume data published September 22, 2026 show Kalshi traded $15.27 billion in contract volume during the week of Sept 14-20, its highest week of 2026, across 85.26 million trades and $3.53 billion of execution-price USD. The week included Kalshi's first $3 billion day, $3.17 billion on Sept 20 after $2.81 billion on Sept 19; sports contributed $3.24 billion and crypto $2.16 billion, versus $188 million of crypto volume at Polymarket Global. Kalshi and Polymarket Global combined for $16.43 billion, up 16.3% week over week, so the record week is a direct read on Kalshi's fee-based revenue run-rate.

Bloomberg reported on 18 September 2026 that Yahoo Finance and Polymarket have ended their prediction-market partnership and that Yahoo Finance has closed the Polymarket-powered prediction markets hub on its site. Yahoo Finance confirmed the wind-down in its own media post the same day, while Finance Magnates reported the two sides keep a separate advertising relationship. Losing a mainstream retail-finance distribution surface removes a significant top-of-funnel channel for Polymarket's US user growth.

It targets Polymarket's election vertical, historically one of its highest-volume categories, ahead of November's midterms.
