The round included Baillie Gifford, Andreessen Horowitz, Coatue, and Morgan Stanley. Kalshi reported over $1tn annualised trading volume, 30m+ accounts, and $1bn+ non-sports revenue.

Commodities and perpetual futures are growing fast, with international retail fees nearing $100m. The company plans expansion into indices, single-stock futures, and global markets. Despite legal challenges—including criminal charges in Utah and Arizona—investors remain bullish.
