Trader consensus on Polymarket assigns a 96.4% implied probability to no Anthropic IPO by June 30, 2026, reflecting the AI lab's deliberate strategy to remain private amid ample venture backing and rapid model advancements. Absent any official announcements, S-1 filings, or banker hires—unlike recent tech IPOs—the market views public listing as unnecessary, especially after Amazon's multi-billion commitment and Google partnerships fueled valuation growth to around $18–40 billion privately. Claude 3.5 Sonnet's strong benchmarks have solidified competitive positioning without market pressures. Challenges could arise from venture capital slowdowns, regulatory demands for capital raises, or accelerated scaling needs outpacing private funds, though AI labs like OpenAI set precedent for extended privacy.
