Historical Price (Probability)

Outcome probability
Date
This prediction market has demonstrated a stable, sideways trend for most of its duration, with the price consistently staying within a narrow range of 1.0% to 6.0%. This indicates that traders have always considered the probability of Tim Cook leaving Apple before 2026 to be very low. The most significant recent price movement is a drop to 3.0%. This price action is a direct reaction to the recent news context provided, where it was announced that Tim Cook's departure would occur on September 1, 2026. Because the market's resolution condition is a departure before 2026, this announcement effectively confirms that the market should resolve to "NO," causing traders to sell "YES" shares and drive the probability down.
The volume patterns support this interpretation of high market conviction. As the price dropped to 3.0% around the date of "2026-05-08", trading volume surged to 344.31 contracts, one of the highest points in the sample data.

4. What potential catalysts before 2026 could accelerate Apple's succession timeline for Tim Cook?

Tim Cook's 65th BirthdayNovember 1, 2025 [^]
Succession Planning AcceleratedLate 2025 [^][^]
Succession Announcement DateApril 2026 [^]
Apple considered various factors and initiated planning for CEO succession. Potential catalysts that could have accelerated Apple's CEO succession timeline before 2026 included Tim Cook reaching 65 years of age on November 1, 2025, which aligns with typical retirement age speculation [^]. Furthermore, Cook's equity awards from 2020 fully vested by 2025, establishing a natural transition window between 2025 and 2028 [^]. The board and executives consequently initiated accelerated succession planning starting in late 2025 [^][^]. Preparations also involved Jeff Williams' retirement at the end of 2023, which may have cleared a path for John Ternus. Ternus subsequently gained design team oversight at the end of 2025, solidifying his candidacy for CEO [^][^][^][^].
The CEO succession occurred in 2026, uninfluenced by health concerns. Despite these earlier catalysts and preparations, the actual announcement for Apple's CEO succession was made in April 2026, with the transition scheduled for September 1, 2026 [^]. It was explicitly confirmed that no health-related catalysts influenced this timeline, as Tim Cook was reported to be healthy in April 2026 [^][^].

Board and Cook affirmed confidence in the leadership transition. Apple Board Chairman Arthur Levinson confirmed that the board unanimously approved this transition, expressing confidence in John Ternus to lead the company [^].

It was publicly announced on April 20, 2026, that Ternus is slated to take over as Chief Executive Officer of Apple, with his tenure officially beginning on September 1, 2026 [^][^].
Tim Cook's operational expertise significantly transformed Apple's supply chain and revenue. With an industrial engineering background and previous experience at IBM and Compaq, Cook became Apple's Senior Vice President of Operations in 1998 before being appointed CEO in 2011 [^][^]. Under his leadership, Apple's revenue saw substantial growth, increasing from $108 billion to $416 billion by fiscal year 2025 [^][^][^]. Cook was instrumental in implementing critical supply chain improvements, including a just-in-time inventory system, which resulted in inventory turning over every five days and a reduction to only 24 primary suppliers [^][^]. Cook is scheduled to remain CEO until August 31, 2026, after which he will transition to the role of Apple Executive Chairman, with Ternus succeeding him as CEO [^][^].

7. Which key product milestones for Apple between now and 2026 might influence the timing of Cook's departure?

Furthermore, a significant overhaul for Siri is expected to be announced at WWDC between June 8-12, 2026, featuring a standalone application, multi-turn conversational capabilities, on-screen awareness, and powered by Gemini [^][^][^].

September 2026 is slated for the introduction of both a Foldable iPhone and the iPhone 18 Pro [^][^][^]. Additionally, a preview of Apple Glasses is anticipated in late 2026 [^][^][^]. These strategic initiatives, encompassing new foldables, a revamped Siri, an enhanced smart home ecosystem, and a shift in wearables, are cited as crucial factors in Cook's decision to step down [^][^].

8. What do historical CEO transitions at tech giants like Microsoft and Google suggest for Tim Cook's exit timeline?

At Google, Eric Schmidt was CEO for 10 years (2001-2011), followed by Larry Page for 4 years (2011-2015). Sundar Pichai's tenure, which began in 2015, will exceed 11 years by 2026 [^].
