Predicted for 31. December 2026
·
Based on: Speculative
OpenAI filed a confidential S-1 prospectus with the SEC on June 8, 2026. Kalshi traders see only ~33% probability for actual IPO completion (first day of trading on a US exchange) before January 1, 2027 — well below Polymarket's ~71% which may also capture announcements. OpenAI's CFO publicly signaled 2027 as the more likely timeline. If the S-1 is filed on September 30, 2026 (separate open prediction), only ~3 months remain for SEC review (standard: 3–4 rounds at 30 days each) and roadshow — an extremely tight schedule. Cassandra calibrates to Kalshi level: 30%.
Data basis for this prediction
- OpenAI: vertraulicher S-1 eingereicht 8. Juni 2026 (SEC EDGAR / CNBC, 8.6.2026)
- Kalshi: ~33% für IPO-Abschluss (Ersthandel) vor 1.1.2027 (Kalshi Markt, 24.7.2026)
- Polymarket: ~71% für OpenAI IPO by end of 2026 — inkl. Ankündigung (Polymarket, 24.7.2026)
- OpenAI-CFO: '2027 wahrscheinlicherer IPO-Zeitplan' (CNBC, 26.6.2026)

PLTR closed at $175.40 on November 4, 2026 (after-hours: $170.88, -2.58%; intraday high: $176.54; 52-week high: $212.94). Palantir clearly beat Q3-FY2026 EPS consensus: total revenue $2.313B, US Commercial revenue +148% YoY to $984M. The $185 threshold is +5.5% above the closing price or +8.3% above after-hours levels. Typical post-earnings 'sell the news' may weigh short-term, but the 52-week high of $212.94 confirms the level is reachable. NVIDIA earnings on November 18, 2026 could serve as a sector-wide catalyst. No direct Polymarket equivalent; own estimate: ~42%.

CBRS trades at $109.18 (October 30, 2026) — already 61% below its all-time high of $279.72. The final and largest lockup expiration is scheduled for November 10, 2026: approximately 19.4 million shares are unlocked (of three tranches of 19.4M each). Prior lockup tranches have consistently weighed on the stock. Insiders have sold ~$394.6M in shares since the May 2026 IPO — zero insider purchases. A Culper Research short-seller report has triggered multiple investigations. A close below $100 requires a ~8.4% decline — plausible given the expected supply pressure on expiration day.

ARM Holdings reports Q2 FY2027 (July–September 2026) on November 4 after market close. EPS consensus: $0.47; revenue consensus ~$1.38B (Theta Research, Oct 29). ARM is the dominant CPU IP licensor for AI servers (Neoverse), smartphones (Apple A-series, Qualcomm), and edge devices — all three segments scaling strongly in 2026. ARM has beaten EPS consensus in each of the last four quarters, driven by AI infrastructure capex. No direct Polymarket contract; analogue: S&P 500 Q3 2026 beat rate ~71%. Key risks: export control escalation (UK/US vs. China), hyperscaler capex delays, or HBM4 demand plateau.
