Palantir Technologies Inc. (NYSE: PLTR) closes above $185.00 per share on at least one trading day in November 2026 — confirmed by Nasdaq or Bloomberg by December 1, 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%.

Cerebras Systems (NASDAQ: CBRS) closes below $100.00 per share on November 10, 2026 (confirmed by Nasdaq or Bloomberg by November 11, 2026)

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 plc (NASDAQ: ARM) beats Q2-FY2027 EPS consensus of $0.47 per share — earnings report November 4, 2026 after market close (confirmed by ARM Holdings Investor Relations or Bloomberg by November 5, 2026, 10:00 AM ET)

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.
