Altman cools on IPO talk as Polymarket prices Vance at 19.55% for 2028
Polymarket 2028 Election Odds: JD Vance Leads at 19.55% as Newsom and Rubio Tighten the Top Tier
OpenAI’s chief executive Sam Altman said he is “0%” excited about running a public company as the ChatGPT-maker moves closer to a potential IPO, according to comments cited in a recent report. The headline has little direct linkage to the Polymarket market “Presidential Election Winner 2028,” where pricing is driven by the relative odds across political contenders rather than corporate listings.
Key Takeaways
- Polymarket’s leading implied winner in “Presidential Election Winner 2028” is JD Vance at 19.55%.
- The market shows a wide field, with Gavin Newsom at 16.05% and Marco Rubio at 15.55% behind the leader.
- The contract is scheduled to resolve on 2028-11-07, with $633,819,374 in volume reported.
OpenAI CEO Sam Altman said he was “0%” excited about being a public company CEO, while acknowledging a public listing could still have benefits for the company. The report said OpenAI filed preliminary confidential paperwork with the U.S. Securities and Exchange Commission, a step that can precede an IPO even if the timing is undecided. OpenAI said it had not decided on a timeline and that it could be “a while,” describing tradeoffs between staying private and going public. The company said it announced the filing because it expected the move would leak. The report also described a prior restructuring that converted OpenAI into a more traditional for-profit company and adjusted Microsoft’s stake to 27%.
