Anthropic IPO before 2027?

Prediction markets put the probability at 66%: Anthropic IPO before 2027. Currently, markets are divided (66% YES, 34% NO). Anthropic has taken significant steps by confidentially filing a draft S-1 with the SEC, while Freshfields is advising the company on its IPO process.

What’s Happening

Momentum toward an Anthropic IPO intensified after the company confidentially filed a draft S-1 with the SEC, retaining Freshfields as legal adviser on the offering. The filing places Anthropic alongside OpenAI and SpaceX in a widening pipeline of mega-cap technology listings, with SpaceX targeting a record raise of more than $75 billion and a listing slated for June 12, 2026. A confidential S-1 is a procedural milestone rather than a firm commitment, allowing issuers to advance private SEC review before setting a public timetable — but it materially shortens the path to a debut before the 2027 resolution window.

Competitive sequencing has become a central variable. OpenAI, which disclosed its own confidential draft filing last month, is weighing a delay to 2027 amid stock-market uncertainty and mounting operating losses, per reporting cited by PitchBook. One outlined scenario — "OpenAI delays, Anthropic goes first" — would cement Anthropic's position as the first pure-play frontier-AI lab to price a public offering. Analysts have framed SpaceX as a potential blueprint for the wave, with Kathmere Capital Management's chief investment officer suggesting its structure could set precedent for incoming Silicon Valley mega IPOs, including a prospective Anthropic IPO. The last comparable frontier-tech cohort to reach public markets did so only after establishing durable revenue visibility, a bar the current entrants are still testing. [PitchBook, Jul 02]

On the fundamentals, Anthropic signed a 20-year lease on Monday for a TeraWulf data center in Kentucky with roughly 400 megawatts of capacity and first power expected in the second half of 2027, a deal projected to generate about $19 billion in revenue and signaling long-horizon capital commitments consistent with public-company scale. Separately, Kalshi traders put odds below 30% that the U.S. government takes a stake in OpenAI or Anthropic this year. Next signposts for the Anthropic IPO question are a public S-1, roadshow terms, and whether OpenAI's decision reshapes the sequence. [CNBC, Jul 07]
