Prediction markets put the probability at 8%: Will OpenAI's valuation hit (HIGH) $2.5T by December 31. Currently, markets see this as unlikely (8% YES). OpenAI engages Citigroup, JPMorgan for IPO discussions by Estefano Gomez | Powered by Vera May.
OpenAI's engagement of Citigroup and JPMorgan for IPO discussions, reported on May 29, 2026, has injected fresh momentum into questions surrounding the company's near-term financial trajectory, including whether OpenAI's valuation hit (high) $2.5T by December 31 is achievable. The banking appointments signal a concrete step toward public markets, with separate market data showing the probability of an IPO by June 30, 2026 priced at just 1% YES, while the likelihood of an IPO by December 31, 2026 stands at a robust 70% YES. Concurrently, the specific market tracking OpenAI's valuation hit (high) $2.5T by December 31 has seen its YES probability climb to 25%, up from 16% the previous day, reflecting a sharp reassessment of the company's growth prospects following the IPO news [Cryptobriefing, May 29].
The valuation question carries heightened significance given parallel developments in the broader technology IPO landscape. SpaceX, a frequent comparator in scale discussions, has been eyeing a $2T IPO valuation while holding $637M in Bitcoin, with reports from May 18, 2026 indicating the company reached a $2.5T valuation on Hyperliquid amid IPO anticipation. This juxtaposition underscores that trillion-dollar valuations are no longer theoretical for private tech giants, yet OpenAI's path to $2.5T by year-end faces distinct hurdles, including executive churn — most recently the departure of CRO Denise Dresser, replaced by Dali Rajic, the former Wiz CRO. The leadership transition, noted in early September coverage, adds operational uncertainty even as the company pursues capital raises reportedly in the $100–300 billion range at a potential $2 trillion valuation discount [Cryptobriefing, May 18].
Looking ahead, the critical test for OpenAI's valuation hit (high) $2.5T by December 31 will hinge on the structure and pricing of any formal IPO filing, as well as the company's ability to stabilize its C-suite. The 8% current YES probability on the $2.5T threshold — a figure that diverges from the 25% reading cited in earlier market snapshots — suggests volatility in trader expectations as new information emerges. Analysts have noted that a smaller market cap company with a larger capital need faces inherent tensions in valuation negotiations, a dynamic directly applicable to OpenAI's fundraising ambitions. With the December 31 deadline approaching, upcoming quarterly earnings from major AI infrastructure partners and any regulatory filings will provide the next data points for assessing whether the company can bridge the gap from its current valuation to the $2.5T mark within the calendar year [Finance, Sep 02].

The single tracked wallet is positioned exclusively on NO at 77c, signaling conviction that OpenAI will not reach a $2.5T valuation by December 31.

With YES at 7c, every YES holder is underwater while all NO positions entered at 77c are in profit, creating strong incentive for NO holders to defend or exit into strength. The absence of profitable YES entries means there is no natural bid-side support from winners, leaving the 7c level vulnerable to further decay. NO-side profit-taking could cap upside, but the dominant NO positioning implies the market sees $2.5T as highly unlikely by year-end.
Polymarket prices YES at 5c with $57K in total volume. Our model estimates fair value at 12c. 7-point gap suggests market may undervalue YES.
