like Kalshi, you can trade on corporate executives who make a career change. And when it comes to Bubeck’s future with OpenAI, that’s exactly what Kalshi is covering.
- Company:
OpenAI
- Employee:
Sébastien Bubeck
- Role:
AI researcher/technician
- ‘Yes’ Probability:
11%
- Total Trading Volume:
$1,000+
Liquidity is very thin here at $1,000. This suggests traders are backing off, which could also mean no one has concrete information about Bubeck potentially leaving OpenAI.
Market setters are making it seem pretty clear that Bubeck isn’t going anywhere. An 11% probability that he leaves OpenAI isn’t something that we would treat as realistic. But this also isn’t proof that his departure is impossible.
Developments Surrounding OpenAI’s Mathematics Controversy
OpenAI recently caused a stir when the company claimed an internal AI system solved the Navier–Stokes mathematical problem. The controversy involved Bubeck and Levent Alpöge, who’s a mathematician at Anthropic.
Tristan Buckmaster, who’s an NYU mathematician, alleged that Bubeck tried to take full credit for solving the Navier–Stokes problem, excluding Alpöge from authorship. Buckmaster surmised that Bubeck did this because of Alpöge’s affiliation with Anthropic. (These are allegations, of course — they’re unsubstantiated.)
What the Evidence Suggests
Despite the Navier–Stokes mathematical controversy, there’s really no indication that Bubeck will depart from OpenAI. As of November, his website still displays OpenAI as his current employer.
Here’s some other recent activity involving Bubeck and his affiliation with OpenAI:
- August: Bubeck participated in a public discussion (hosted by OpenAI) regarding AI's role in mathematics
- October: Public comments from Bubeck involve OpenAI's new mathematical and computer-science discoveries
- November: Not a single verified source can confirm that Bubeck is leaving the company
Our Prediction: Bubeck Isn’t Going Anywhere
It’s no surprise that traders on
tech prediction sites
like Kalshi aren’t very bullish on Bubeck leaving OpenAI. But that’s just one reason why we’re picking ‘No’ on this market. The truth is, all publicly available information suggests he’s not going anywhere.
