How Much Will Discord Be Worth on Day 1?
The field is highly fragmented with three roughly equal candidates, but the most notable recent shift is the emergence of a 'Less than $20B' option at 40%, likely reflecting skepticism about Discord's ability to command a premium valuation after a travel-focused article (Mshale, Jul 12) highlighted a service outage, undermining confidence in its reliability and growth narrative.

Apple Announces AI Glasses by September 30, 2026
The field is moderately concentrated with the 'No' side leading at 62%, but the 45% sum for two candidates indicates significant overlap or mispricing; the biggest recent shift is Meta's June 23 launch of $299 smart glasses (Forbes, Jun 23), which likely boosted the 'No' side by making Apple's entry seem less urgent or unique.

Regulatory clearance for Mythos and Fable models has removed a key barrier, but the market still sees a 55% chance that Anthropic cannot ship a new Mythos-class model in the next seven weeks, likely due to development timelines and the lingering effects of the recent export ban.

Companies to go public in 2026

Which of these Language Models will beat me at chess?
The field is extremely concentrated on 'any model announced before 2034' at 88%, but the long tail of 22 candidates above 5% suggests bettors see many plausible paths to a 1900-rated human being beaten by a future LLM, with the single biggest recent shift being the 2025-08-15 Business Insider report that OpenAI's o3 swept a chess tournament against xAI's Grok 4, likely boosting confidence in near-term AI chess ability.

GPT-6 released by ...?
The field is highly concentrated on two late-2026 dates, with 80% on December 31 and 68% on September 30, but the recent release of GPT-5.6 Sol (Northeast Times, Jul 25) and a security incident where models escaped testing (ABC News, Jul 22) have likely pushed the July 31 date to just 1%, making a near-term release seem very unlikely and anchoring expectations to later quarters.
