Polymarket’s market on whether the AI industry suffers a downturn by 30 June 2027 traded at 26.5% on Saturday morning, up from 22.5% before Thursday’s AI selloff, after touching 31% at Thursday’s end, according to Polymarket’s price data (Polymarket).
The market does not resolve on sentiment. It needs three of six listed events inside one 90-day window, and three of the six are stock-price triggers. By our arithmetic on Nasdaq closing prices, the iShares semiconductor ETF closed 37.5% below its record on Friday, against a 40% trigger, and Nvidia closed 22.0% below its record, against a 50% trigger.
Business Pill · Financial Conditions Explained
A short explainer on financial conditions, how the price and availability of money move markets. It teaches the general idea only and does not discuss this story.
The key insight: By our arithmetic, Polymarket’s June 2027 ‘AI bubble burst’ market rose 8.5 points to 31% on Thursday and gave back 4.5, while the nearest of its Nvidia and chip ETF triggers, SOXX’s 40% drop, was missed by 0.4 points that day.
The rules define an “industry downturn” as at least three of these events within a single 90-day window: Nvidia closing 50% below its all-time high; the iShares PHLX Semiconductor ETF (SOXX) closing 40% below its all-time high; OpenAI or Anthropic declaring bankruptcy; OpenAI being acquired; H100 rental prices at $1.00 or lower for five straight days on the SiliconData index; or TSMC, ASML, Broadcom, Arista or Super Micro closing 50% below its all-time high.
The rules add that the market “will not resolve to “Yes” until three conditions have been met, regardless of reporting of an industry downturn or similar claims”. That line is from the 2026 version of the market, which carries the same list of events.
Polymarket ‘Yes’ prices for two ‘AI bubble burst’ markets (by 30 June 2027, and within 2026), last trade of each UTC day, 15 October to 7 November 2026. Each resolves Yes only if three of six listed events occur within one 90-day window. Data: Polymarket price history, read 7 November 2026 06:40 UTC.
How the Price Moved
On the last trade of each UTC day, the June 2027 market went from 22.5% on 4 November to 31.0% on 5 November and 26.5% on 6 November. That is a rise of 8.5 points and a fall of 4.5, by our arithmetic. About $94,000 has traded on it since it opened on 22 September.
A larger sister market on a downturn within 2026, with about $2.64 million traded, went from 6.9% to 12.5% and back to 7.65% over the same three days. Both prices are crowd bets on the rules above, not forecasts by any company or analyst.
How Close the Triggers Are
By our arithmetic on Nasdaq’s daily closes since January 2024: SOXX closed at $136.53 on 6 November, 37.5% below its $218.34 record close on 22 June. On 5 November it closed at $131.90, 39.6% below the record and about $0.90 above the $131.00 level that marks a 40% drop (Nasdaq).
Nvidia closed at $186.64, 22.0% below its $239.24 record close on 6 October; a 50% drop would put it at $119.62. Among the five named suppliers, Broadcom closed 39.0% below its record, ASML 28.4%, TSMC 22.7% and Arista 21.2%. Super Micro closed at $28.76, 75.8% below its record close of $118.81 on 13 March 2024.
The market text says the three events must occur within one 90-day window. It does not say whether a decline that began long before the window, like Super Micro’s, counts as an event inside it. We did not read the SiliconData H100 index for this piece.
Our Numbers
By our arithmetic: the June 2027 market rose 8.5 points in a day and gave back 4.5; SOXX ended Thursday 0.4 points short of its 40% trigger and Friday 2.5 points short; Nvidia sits 28 points short of its 50% trigger; Broadcom sits 11 points short of the supplier trigger.
Connecting the Coverage
The odds moved with the selloff that took $1.45 trillion off 12 AI stocks on Thursday (our piece) and the partial rebound into Friday’s close (our piece). Prediction markets also repriced Anthropic’s IPO this week (our piece), and AI cloud shares fell 20.9% in four sessions (our piece).
The Structural Read
As we read the market rules, the contract is narrower than its name: it pays only on three listed events inside 90 days, not on any loss of confidence.
As we read the price path, the 2026 market, where most of the money trades, moved less in points and fell back almost to where it started.
As we read the Nasdaq closes, the chip ETF has done most of the falling: it sits 37.5% below its June record, against 22.0% for Nvidia.
Polymarket’s rules for its ‘AI bubble burst in 2026?’ market
“will not resolve to “Yes” until three conditions have been met, regardless of reporting of an industry downturn or similar claims”
Three Implications
FOR READING THE HEADLINE ODDS The 31% was the June 2027 market, with about $94,000 traded; the 2026 market, with about $2.64 million traded, ended Friday at 7.65%.
FOR CHIP STOCKS SOXX closed at $131.90 on 5 November, about $0.90 above the $131.00 level that marks 40% below its record, by our arithmetic.
FOR THE SUPPLIER EVENT Super Micro closed 75.8% below its March 2024 record, and the rules do not say whether a decline that old counts within the 90-day window.
The analysis says: “The bubble can pop on the short cycle while the supercycle continues uninterrupted on the long cycle, exactly the way the dot-com bust did not stop the internet from becoming the substrate of the next thirty years.”
As we read it, a Polymarket contract like this one prices only the short cycle, in stock drawdowns over 90 days; the analysis does not discuss prediction markets.
What Is Not Established
A Polymarket price is the going rate for a contract, set by the traders who use it, and the June 2027 market is thin at about $94,000 traded. Nothing here says any of the six events will happen. Nasdaq’s history is our record-close source; Polymarket may use its own data to settle.
This Week In The AI Supercycle
Anthropic’s Reality Check, The Capital Squeeze, & The New World Order
This week’s issue: for two years the AI build-out was priced as a growthstory. This week it started being priced as a credit story.
Polymarket’s June 2027 ‘AI bubble burst’ market traded at 26.5% on 7 November after reaching 31% on Thursday. Of its Nvidia and chip ETF triggers, SOXX is the nearer: it closed 37.5% below its record on Friday, against 40%, while Nvidia was 22.0% below, against 50%. Whether Super Micro’s earlier fall counts toward the supplier event is not settled by the rules.
A note on sourcing. Market rules, prices and volumes come from Polymarket’s own market pages and price history, read on 7 November 2026; stock closes come from Nasdaq’s historical quotes. Point changes and distances to each trigger are ours. Nothing here is investment advice.
