Open interest in futures linked to the AI developer has climbed to about $79.27 million, close to a record $80 million, as traders position around what could become one of the largest initial public offerings ever. This activity is unfolding even though Anthropic has yet to disclose an offering price, final valuation, or number of shares it intends to sell. CoinGlass data shows its ANTHROPIC pre-stock contract trading around $2,147, with Binance accounting for roughly 40% of the activity. Anthropic confidentially filed a draft registration statement with the US SEC in June and now plans to stage the IPO in November, later than the previously expected October timetable. Circle CEO Jeremy Allaire has urged Anthropic to embrace public scrutiny by completing its transition to public markets.
