Jony Ive–OpenAI Earbuds Outcome Hits 53% on Sweetpea Leak

Leaked 'Sweetpea' Earbud Specs Are Driving the Ive-OpenAI Prediction Market, Not the Phone Headlines

While mainstream tech journalists spent the past week dissecting an April 27 Tom's Guide report about OpenAI building a smartphone, prediction market traders moved in the opposite direction. Over the past 72 hours, the Earbuds/Headphones outcome in the "What kind of device will Jony Ive and OpenAI announce?" market surged from 30% to 53%, a 24-percentage-point repricing that represents one of the sharpest moves this contract has recorded.

The timing matters. This move did not follow a press conference or a corporate filing. It followed the wider circulation of supply chain details about a project codenamed "Sweetpea," which describes a device that is unmistakably an earbud or headphone product, not a phone. The market is now majority-confident in earbuds as the form factor OpenAI will announce before December 31, 2026, even though a MacRumors report from February confirmed the device launch has slipped to 2027. Traders appear to be distinguishing between "announce" and "ship," betting that an announcement can still occur this calendar year.

The platform spread reinforces that this is not a single-exchange anomaly. Kalshi prices the outcome at 58%, while Polymarket sits at 48%. Both moved up sharply from their respective lows, and the 10-percentage-point gap between platforms suggests Kalshi traders have slightly higher conviction, possibly reflecting access to different information channels or a different risk appetite.

What the 'Sweetpea' Leak Actually Says About Jony Ive's OpenAI Device Plans

The case for earbuds rests almost entirely on the Sweetpea codename and its associated hardware details. According to Technetbook's supply chain report, the device features a charging case shaped like a smooth stone that houses two capsules worn behind the ears. It is not a phone. It is not a tablet. The industrial design language is explicitly audio-wearable.

The technical specs lend further credibility. The device reportedly uses a custom chip fabricated on a 2-nanometer process, with Samsung Exynos as a likely candidate, though OpenAI may be developing a proprietary processor. Foxconn is named as the manufacturing partner. Internal sales targets cited in the report range from 40 to 50 million units per year, a figure that only makes sense for a consumer wearable priced in the $200–$400 range, not a niche phone.

Jony Ive's design biography strengthens the earbud thesis. His LoveFrom studio is collaborating directly with OpenAI, and his most commercially successful hardware designs at Apple included AirPods, a product that redefined the earbud category. Traders familiar with Ive's portfolio likely see earbuds as a natural starting point for an AI-native device: always-on, voice-first, minimal interface friction. OpenAI has reportedly planned five hardware products through 2028, and earbuds represent the lowest regulatory and manufacturing risk for a first announcement.

Phone-First Press Coverage Puts the 53% Earbuds Price in Direct Conflict With Reported OpenAI Strategy

The strongest case against the current 53% price comes from OpenAI's own reported priorities. The Tom's Guide report from April 27 describes a phone project developed with LoveFrom that aims to "integrate AI agents capable of performing a wide range of tasks." Spanish outlet Cinco Días corroborated the phone-first framing the following day, placing Ive squarely at the center of a handset initiative meant to challenge the iPhone.

If OpenAI's internal hierarchy prioritizes the phone, the "announcement" this market resolves on could easily be a phone reveal at a fall event, with Sweetpea relegated to a secondary accessory introduced later. The 2027 delay reported by MacRumors could apply to the earbud project specifically, meaning the phone might be the product OpenAI announces first, even if it ships later.

Historical base rates also cut against the market's current bet. Leaked codenames in consumer hardware frequently describe products that never reach announcement. Apple's own history includes codenames for abandoned audio products. The market is assigning 53% probability based on a single supply chain report from an outlet that has not been corroborated by any primary source at OpenAI or LoveFrom.

For 53% to be correct, traders need to believe three things simultaneously: that Sweetpea is real, that OpenAI will announce it before December 31, 2026, and that the announcement will clearly identify the device as earbuds or headphones rather than framing it as part of a broader hardware ecosystem. Any one of those assumptions failing would push this contract back toward 30%. The phone-first coverage is not noise. It reflects real sourcing from people inside the project. The market is making a direct bet that the journalists covering this story have the form factor wrong.
