Predicted for 31. October 2026

Based on: Speculative
Polymarket prices the probability of an Anthropic IPO by end of October 2026 at approximately 62%. According to Yahoo Finance/Seeking Alpha, Anthropic has confidentially filed an S-1 and retained Goldman Sachs, JPMorgan, and Morgan Stanley as lead underwriters. The strategically targeted listing window sits just before the US Midterm elections on 3 November 2026, securing capital market access independent of a potential congressional power shift. The roadshow is reportedly set to begin in mid-October. OpenAI CEO Sam Altman explicitly called a 2026 IPO for OpenAI 'ill-advised' — positioning Anthropic as the uncontested first-mover in the 2026 AI IPO market with a target valuation of approximately $2 trillion. Polymarket also sees 87% probability that Anthropic goes public before OpenAI.
Data basis for this prediction
- Polymarket: Anthropic IPO bis Oktober 2026 = ~62 %; vor OpenAI = ~87 % (Stand 14.09.2026)
- Yahoo Finance / Seeking Alpha: Anthropic S-1-Einreichung, Konsortium GS/JPM/MS (September 2026)
- OpenAI CEO Altman: 2026-Börsengang 'ill-advised' (Bloomberg, September 2026)

Google Cloud posted ~$11.35B in Q3 2024 and grew 25–30% per year through H1 2025 (+28–29%). This yields an estimated Q3 2025 base of ~$14.3–14.6B and a Q3 2026 analyst consensus range of ~$17–19B. The $17.0B threshold requires only ~16–19% YoY growth versus Q3 2025 — well below the historical trend. Alphabet has no standalone revenue forecast in the platform's open predictions. No cloud market analyst forecasts Q3 2026 below this level. Note: this is a pure event forecast, not an investment recommendation.

AWS has emerged as Amazon's key growth engine in 2025–2026 amid the AI infrastructure boom. The already open Cassandra forecast for AWS Q4 FY2026 (October–December, published February 2027) sets a >35% threshold; the preceding Q3 (July–September) could be even stronger as GenAI enterprise workloads continue scaling. AWS growth was ~33–36% YoY in late 2025; enterprise AI infrastructure migrations could push Q3 2026 to 37–42%. No direct Polymarket market available.

The Digital Markets Act (DMA) has been in force since March 2024. The European Commission opened preliminary proceedings against all four gatekeepers (Apple, Alphabet, Meta, Amazon) between March and May 2024. At a typical EU enforcement timeline of 18–30 months post-opening, a final fine decision would fall between September 2025 and November 2026 — within the target window. The DMA permits fines up to 10% of global annual turnover; a first symbolic decision above the €1B threshold is historically plausible (EU antitrust fines on Google 2017–2019: €2.4B / €4.3B / €1.5B). Risk: political slowdown driven by transatlantic trade negotiations (Trump administration 2025/26) could push a final decision past October 2026. Probability 38% — uncertain but verifiable prediction with genuine occurrence potential.
