New Apple CEO: John Ternus Has The Job. His First Keynote Is Already

For years, "who succeeds Tim Cook" was the favorite parlor game in tech. As of September 1, 2026, it is not even a question: Apple's leadership page lists John Ternus as chief executive officer, Cook has moved to executive chairman of the board, and the transition Apple announced on April 20 executed exactly on the day it named. Markets do not linger on answered questions, though, and this one did not wait for the ink. On August 31 at 5:45pm UTC, while Cook was still CEO, Kalshi, a CFTC-regulated exchange, listed a 20-market board on a much stranger question: which words will John Ternus say during his first keynote on September 9? This page spent August tracking whether the handover would happen. It happened. So the page turns with the market, from a contract that is now a formality to a board that is pure Ternus-era price discovery, with one oddity worth flagging up front: the busiest contract on the new board is not about anything Ternus might announce. Hold that thought.

The Quick Answer

The new Apple CEO is John Ternus, effective September 1, 2026. The handover Apple announced on April 20 executed on schedule, and Tim Cook is now executive chairman of the board. Kalshi's contract on Cook being out of the CEO seat before January 1, 2027 is pinned at the ceiling, 99¢ bid against a $1.00 ask as of September 1, and is set to resolve Yes once Kalshi settles it; our eight price-blind models blended to 99.0% on completion back on August 7 and are one settlement away from grading correct. The live question has moved: Kalshi now lists a 20-market board on his September 9 "Surprise and shine" keynote, 19 of them on the exact words he says: Ultra 76¢, Apple Intelligence 71¢, Fold 65¢, and a Hardware contract that says the hardware engineer is barely better than a coin flip to say the word "hardware." The full board, and why its housekeeping contract did two-thirds of the day-one volume, is below.

The Handover, Executed

The record is short and every line of it is sourced. On April 20, 2026, Apple's newsroom announced that Cook would step down as CEO and become executive chairman, with Ternus (product design team in 2001, vice president of Hardware Engineering in 2013, senior vice president and executive team in 2021) taking the title on September 1. The board approved it unanimously. Cook: "John Ternus has the mind of an engineer, the soul of an innovator, and the heart to lead with integrity and with honor." Board chair Arthur Levinson, who becomes lead independent director: "We believe John is the best possible leader to succeed Tim."

Then it simply happened. Cook's last day as CEO was August 31. On September 1, Apple's leadership page flipped: Ternus is CEO and holds the board seat that comes with the title, Cook is executive chairman. No delay, no dispute, no drama, which is exactly the scenario this page's model panel had at 99%. Between the announcement and the handover, the only new fact that mattered for the contract was a date: Apple's August 26 invites set a September 9 keynote, tagline "Surprise and shine," Ternus's first as chief executive, with reporting from Bloomberg and CNN pointing to the iPhone 18 Pro lineup and a possible first foldable iPhone.

There is almost nothing left to argue on the outcome side of this price, but there is one last thing to learn from it. On August 7 this contract quoted a 99.5¢ midpoint. By August 14 it had slipped to 98.5¢ on about 16 hundred contracts of flow, and we wrote at the time that a one-cent-wide quote at the ceiling is the signature of a market that agrees, not one changing its mind: read the bid-ask, not the price history. The handover week proved it. The midpoint walked back up to 99.5¢, the bid sat at 99¢, and the roughly 5,500 contracts that traded between mid-August and September 1 were positioning for settlement, not doubt. A market can wobble a cent on thin flow and still be telling you exactly one thing.

The Panel's Number, One Settlement From Grading

We ran this panel on August 7, with 25 days still on the clock: eight models, the same primary-source card, price-blind, asked to price the completion question. Does the announced transition actually make Cook a former CEO before January 1? Each seat then read the others' anonymized reasoning and could revise. These are the post-revision numbers, unchanged since; the run is now a record, not a forecast.

Model	Cook no longer CEO before Jan 1, 2027
Claude Fable	98.5%
Claude Opus	98.5%
Claude Sonnet	99.3%
GPT	98.7%
Gemini	99.5%
Kimi K3	98.5%
GLM 5.2	98.8%
DeepSeek V4	99.8%

Model estimates generated 2026-08-07.

Every seat on this panel is graded against real market settlements — records to date: Claude Fable 83% on 526 graded calls · Claude Opus 85% on 596 graded calls · Claude Sonnet 84% on 574 graded calls · GPT 84% on 5,566 graded calls · Gemini 86% on 4,337 graded calls · Kimi 83% on 2,363 graded calls · GLM 81% on 2,385 graded calls · DeepSeek 80% on 2,410 graded calls, as of our August 14 stamp. The full scoreboard is public and recomputed daily.

The blend lands one settlement away from grading correct, and the interesting part in hindsight is what the missing point was made of. No seat doubted the plan; the point and a half the cautious seats held back was a named tail, a successor-side derailment before September 1 that forces the board to ask Cook to stay. That tail expired quietly on August 31. The panel's other structural read, that incumbent-side shocks resolve Yes rather than No because they make Cook a former CEO faster, never got tested. When Kalshi formally settles the contract, the 99.0% goes on the public scoreboard like every other number we publish.

Where The Panel Changed Its Mind (The August 7 Run)

DeepSeek (0.25% → 99.8%): the round's best catch was a seat catching itself. Its round-one number came back inverted, a flipped scale on its own stated reasoning, and reading the anonymized panel exposed it immediately: "I realized I had inverted the outcome when writing my round-1 number; my reasoning always supported near-certain completion." The revision round exists precisely to catch this class of error before it reaches a reader.

Claude Opus (97.5% → 98.5%): moved a full point on the shock-asymmetry argument, that incumbent-side shocks resolve Yes, not No, "which I had incorrectly counted in my residual."

Claude Sonnet (held 99.3%): "no peer introduced a mechanism or fact I hadn't already weighed." A hold with a stated reason is a data point too.

The Market Moved On Before He Had The Job

Here is the part that makes this page worth keeping open past settlement. Kalshi listed KXAPPLEMENTION-26SEP09 ("What will John Ternus say during his Apple Keynote?") on August 31 at 5:45pm UTC, before Ternus had spent a single minute as CEO. It is a mention board: 19 contracts that each resolve Yes if Ternus says a specific word or phrase during the September 9 keynote, plus one housekeeping leg that pays only if the qualifying event never happens, all settled from the live broadcast, with Kalshi falling back to official transcripts if video alone cannot decide it. The rule text is charmingly literal. The Fold contract, verbatim: "If John Ternus says Fold / Folding / Foldable as part of Apple Surprise and Shine address, then the market resolves to Yes."

The full board, as of September 1, 2026, 12:05 UTC:

Contract	Yes bid	Yes ask	Day-one volume (contracts)
Ultra	76¢	80¢	0
Apple Intelligence	71¢	80¢	0
Fold / Folding / Foldable	65¢	71¢	333
Siri	63¢	68¢	22
Aluminum	55¢	61¢	22
Hardware	55¢	60¢	592
iOS 27	44¢	51¢	142
Ecosystem	35¢	42¢	48
Health / Fitness	31¢	40¢	0
Heart Rate	26¢	35¢	0
Apple TV	25¢	32¢	70
Satellite	21¢	30¢	0
Dynamic Island	20¢	29¢	0
AirPods Pro	19¢	26¢	50
AirTag	16¢	25¢	0
Afford / Affordable	16¢	25¢	0
Apple Watch SE	11¢	15¢	0
Chip	4¢	59¢	159
Tariff	2¢	9¢	4
Event Does Not Qualify	0¢	19¢	2,715

Now the payoff on that oddity from the top. The board matched roughly 4,150 contracts in its first 18 hours, and about 2,700 of them, two-thirds of everything, went through the housekeeping leg at the bottom: "Event does not qualify," the contract that pays only if the qualifying keynote never happens. Read the price history on that leg and it looks alarming — the last print sits at 90¢, as if somebody paid near-certainty for the keynote falling through. Read the book, at the same 12:05 UTC stamp, and the story collapses: the quote sits at a 0¢ bid against a 19¢ ask, a 90-point fall from that print to the current bid, with two-thirds of a brand-new board's volume concentrated in this single leg. That looks far more like a one-sided opening print than price discovery, and the gap between the price history and the book is the real lesson about what day-one volume on an 18-hour-old board is worth. With Apple's invites out since August 26 and a confirmed 1pm ET start, the book prices the no-event scenario as a near-impossibility, whatever the opening tape says. The words come next, and the argument has barely started: nearly half these contracts have not traded at all.

Prices refresh during the news cycle.

Every pre-event leak reprices this board, so the quotes above carry an as-of stamp and get re-read on our standard market-pulse cycle through September 9. The argument's shape carries the piece; the dated quote is the evidence.

Reading The Board: What 76¢ On "Ultra" Actually Says

The top of the board is a rumor sheet with prices attached, and most of it is quotes rather than trades. Ultra at 76¢ is an offer nobody has taken yet (zero contracts traded), a resting order's read of the reporting that puts an iPhone Ultra name in the September 9 lineup, not the crowd's; Apple Intelligence at 71¢ is the same, an untraded quote saying the AI branding survives the CEO change. Fold at 65¢ is the one with real volume behind it, tracking the foldable-iPhone reporting from Bloomberg and CNN. None of those resolve on whether the products are real, only on whether Ternus personally says the word on stream during the address.

The rule of mention boards: price the script, not the product. A foldable iPhone could headline the event and the Fold contract still dies at zero if Ternus hands that segment to a lieutenant.

The fine print sharpens that edge further. Kalshi's payout criteria count "the exact phrase/word, or a plural or possessive form," require the words to come from "John Ternus speaking in an official capacity," and exclude other grammatical and tense inflections along with hot-mic moments and archival footage. So "foldables" pays the Fold contract but "folded" does not, a demo video narrated by anyone else pays nothing, and for slash-listed contracts like Fold / Folding / Foldable, any one of the listed words is enough. There is even a rulebook answer for disaster: if the event is cancelled or fails to qualify, the housekeeping leg pays and every word contract resolves No, while a postponement of up to 14 days just keeps the board open.

Which is why the row I keep coming back to is Hardware at 55¢ bid, 60¢ ask. John Ternus ran Apple's hardware engineering organization for 13 years, the last five as senior vice president; the April announcement quotes Cook praising his engineer's mind; and the market says he is barely better than a coin flip to say the word "hardware" out loud at his own product launch (ignore that row's 7¢ last print — 592 contracts through another opening-print artifact, which is exactly why you read the book, not the price history). That is not a judgment about Ternus's priorities. It is a reminder that keynote scripts say "iPhone" and "titanium" and "all-day battery life," not the org-chart word for the division that builds them. The iOS 27 contract at 44¢–51¢ carries the same lesson in reverse: the new iOS build is a September staple, but the naming convention itself is the bet, and the market is split on whether "iOS 27" is what Ternus calls it out loud. Price a mention market on how people talk, not on what is true.

And respect the spreads. Every quote we have stamped on the Cook contract has been one cent wide; this board is quoted 5¢ to 9¢ wide almost everywhere, and the Chip contract (4¢ bid, 59¢ ask) is barely a quote at all. On a book this young and this thin, the ask you pay matters as much as the side you like, and a resting order can move a midpoint more than any headline. That was the lesson of the Cook contract's August wobble, and it applies double here.

A Worked Example: What Buying Fold At 71¢ Actually Costs

Take the most traded of the rumor-sheet contracts and run the arithmetic. Fold is quoted 65¢ bid, 71¢ ask, a 68¢ midpoint that reads as roughly a 68% chance Ternus says "fold," "folding," or "foldable" during the address. You cannot buy the midpoint. A Yes buyer lifts the 71¢ ask, risking 71¢ to win 29¢, which prices Yes at 71%, three points above the midpoint's read; a No buyer pays 35¢ (one dollar minus the 65¢ Yes bid), risking 35¢ to win 65¢, which prices No at 35% when the midpoint says 32%. Add the two sides' asks together and you get 106¢ on a contract that pays 100¢; that extra 6¢ is the spread, and on a young book the spread is the toll: it goes to whoever left the resting order, not to you. Compare the Cook contract, one cent wide on every stamp we took: there, the tight quote made the price a clean probability proxy, give or take rounding. Here, being right about the script and still paying the wide side of a thin quote can eat a meaningful share of your edge before the keynote starts. The number to respect is not 68%; it is the 6¢ between what buyers pay and what sellers get.

What To Watch Before September 9

• The Settlement, First. By our read of its early-close rule, the Cook contract closes at the first 10am ET after the event, the morning of September 1 on this timeline; it was still quoted when we stamped this page at 12:05 UTC. When it grades, the panel's 99.0% grades with it, in public.
• The Empty Top Of The Board. Nine of the 20 contracts have traded zero volume, and they include the two highest-priced rows, Ultra at 76¢ and Apple Intelligence at 71¢. A 76¢ quote with no trades behind it is a resting order's opinion, not a market's. Every credible pre-event report about the Ultra name or the foldable moves those rows directly; the first real flow into them is the day this board starts meaning something.
• The Script Question. Any reporting on how Apple structures the keynote, meaning how much Ternus fronts personally versus hands off, reprices the whole board at once, because every contract requires the words to come from Ternus himself during the address.
• The Board Stays Open Past The Event. The mention markets list a September 24 close, but they become determinable the moment the September 9 stream ends; expect settlement to move on Kalshi's standard video-review timeline, not the outside date.

Settlement Timeline

Date	What happens
September 1, 2026	Executed: Ternus is CEO and joins the board, Cook is executive chairman, Levinson becomes lead independent director. The Cook contract's event has occurred; per its rule, the market closes "the following 10am ET"
September 9, 2026	The "Surprise and shine" keynote, 1pm ET: Ternus's first as CEO, and the resolution event for the 19 mention contracts and the housekeeping leg
After September 9	Mention markets settle from the broadcast video, official transcripts as the fallback. We grade every number on this page in public on the scoreboard

The Bottom Line

The succession question that filled a decade of tech punditry closed on schedule and closed quietly: John Ternus runs Apple, the contract that priced the handover is pinned at 99¢ waiting on paperwork, and the panel's 99.0% is a settlement away from its grade. What the week actually revealed is how little time an ending buys: settlement mechanics were still finishing the old contract while the crowd was already pricing the next question. Hours before Ternus had the title, Kalshi was trading his vocabulary, and the first thing that new board priced was its own fine print. By September 9 the argument will have moved from whether the event qualifies to whether the hardware engineer says "hardware." This page will re-read the board as it fills in, same as it read the last one: bid-ask first, tape second, story third.

To be explicit: nothing here is a prediction of fact or financial advice. It is a set of market prices and model estimates with a public graded record, built from Apple's own primary-source announcements and Kalshi's published rules. Every number gets graded when its market settles.
