Reuters reported on September 4 that Anthropic is expected to begin marketing its initial public offering in mid-October at the earliest and wrap up the listing days before the US midterm elections in November. The artificial intelligence company had been set to release its IPO prospectus as early as the following week according to two of the people cited in the dispatch. That release has now slipped to late September though the sources cautioned that the full timetable including these dates remains subject to change as preparations advance. Companies routinely revise IPO schedules to align with market conditions regulatory feedback and internal readiness the news service added.
A late August dispatch from Reuters had cited The Information as saying Anthropic would unveil its prospectus after Labor Day with a potential debut in late September or early October. The latest adjustment comes as the firm works through the final stages of what could become one of the largest public offerings on record. Such changes are not unusual and do not necessarily indicate problems with the transaction itself according to the September 4 report.
Some investors have indicated the listing could value Anthropic at approximately $2 trillion Reuters reported which would place it among the biggest IPOs ever attempted and serve as a key gauge for public market appetite in the artificial intelligence sector. StockAnalysis.com figures show the company’s post-money valuation reached $965 billion after its Series H round in May 2026. The data service places total funding to date at more than $133 billion a sum that highlights the resources required to scale advanced AI development.[[1]](https://stockanalysis.com/private/anthropic/valuation/)
As part of the IPO process Anthropic aims to finalise a $15 billion revolving credit facility before analysts including those at the financing banks meet with the company one of the people told Reuters. Bloomberg News had earlier reported that the firm was in talks to expand the facility to that level from an existing arrangement. The credit line would supply additional liquidity as the company continues to invest heavily in compute infrastructure to meet demand for its Claude models.
The Financial Times reported that Morgan Stanley and Goldman Sachs are in discussions for lead roles in the offering with JPMorgan also participating in preparations. Anthropic confidentially filed its S-1 with regulators earlier in 2026 setting the formal review process in motion. A June analysis published by IndMoney projected that the timeline could still support an October listing despite the adjusted marketing window.
Anthropic has raised at least $130 billion to support its operations a figure highlighted in the late August Reuters report on the company’s plans. The funding underscores the capital intensive nature of developing advanced AI models in competition with rivals such as OpenAI which has signalled a later public market entry. Reuters added that the IPO would distinguish itself by potentially allowing existing shareholders to sell shares a departure from some recent large tech debuts.
