Resolution criteria on PolyGram: This market will resolve to "Yes" if Apple officially releases iPhone 18 by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". A qualifying product must be named "iPhone" and be recognized as a successor to the original iPhone product, similar to the relationship between iPhone 15 and iPhone 16. A new iPhone product released without a number, under a designation other than iPhone 18, will qualify if it retains the original functions of the iPhone and expands on them in such a way that it is clear that this product is a successor. In order to be considered released, the product must be available for purchase by the general public within the specified timeframe.
PolyGram is an on-chain prediction market where you trade YES or NO outcome shares with real USDC on Polygon. For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution. Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.
Market outcomes
| Will Apple release iPhone 18 in 2026? | 97% YES | 3% NO |
Apple's annual iPhone release cycle has been remarkably consistent for nearly two decades. The company released iPhone 16 in September 2024, following the established pattern of autumn announcements and launches. Given this cadence, an iPhone 18 release by end-2026 would require Apple to skip a generation or significantly accelerate its product timeline—neither of which has occurred in the company's recent history. The 97% implied probability on Polymarket's order book reflects the near-certainty that Apple will maintain its biennial naming convention and annual release schedule through 2026.
Historical precedent strongly supports the crowd's positioning. Since iPhone 6S in 2015, Apple has released a new numbered iPhone every twelve months without exception. iPhone 15 arrived September 2023, iPhone 16 in September 2024, establishing the pattern that iPhone 17 should launch September 2025 and iPhone 18 in September 2026. No external factors—regulatory, supply chain, or competitive—have disrupted this rhythm in over a decade. Apple's financial guidance and capital allocation consistently support maintaining this release cadence.
The primary catalyst remains Apple's September 2026 announcement event, typically held in the second or third week of the month. Traders should monitor any deviations from Apple's standard product roadmap signalling through earnings calls or supply chain reporting in mid-2026. The settlement window extends through December 31, 2026, allowing for any delayed launches, though such delays would represent a material departure from established practice.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
The mechanics for trading "Will Apple release iPhone 18 in 2026?" are the same as any other PolyGram event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$95K in lifetime turnover and $4K of resting liquidity puts this market in the top 30% by volume for big tech contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
Last 24 hours alone saw $74 in turnover, consistent with the market's lifetime daily-average pace.
The market has been open for 5 months — the price has had time to stabilise as new information arrived.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
As of today, traders on Polymarket price this outcome at 97%. The number updates continuously as the order book clears. PolyGram mirrors the same live odds with locale-aware formatting and USDC settlement.
