ThinkMarkets launches 24/7 pre-IPO markets on Anthropic and OpenAI

LONDON, Oct. 28, 2026 (GLOBE NEWSWIRE) -- Traders can go long or short on the two AI companies as it breaks, including overnight and on weekends, before either company's shares begin trading. ThinkMarkets has launched pre-IPO markets on Anthropic and OpenAI, allowing traders to take a long or short position on what each company will be worth at the end of its first day of trading. Both instruments are quoted 24 hours a day, seven days a week, so traders can respond to developments such as filing announcements, roadshow updates, and valuation reports whenever they emerge. The launch comes as both companies move towards public markets.
