Anthropic’s listing timetable has reportedly moved back, on the account of sources cited by CNBC, which credited the reporting to Reuters. The AI company is now expected to begin marketing the offering no earlier than mid-October, with a listing targeted for the days just before the November U.S. midterm elections, the sourcing said on Friday, September 5, 2026.
A public prospectus, previously anticipated within days of that report, is now expected in late September, per the same sourcing. Some investors have floated a valuation near $2 trillion for the offering, which would rank among the largest ever attempted, CNBC noted, though nothing here has been confirmed by Anthropic, which declined to comment.
CNBC’s reporting cautions that IPO calendars shift routinely as companies work through market conditions and regulatory review, so the dates could move again. A listing clustered around a national election adds a second variable: investor appetite tied to political uncertainty as much as offering readiness. Founders eyeing a late-2026 liquidity event should treat mid-October as a floor, not a fixed date.
CNBC, citing Reuters and people familiar with the matter, reported the timeline on September 5, 2026.
