Where the claim came from

The claim — that OpenAI has "reversed" enterprise market share, moving from chaser to leader among corporate AI buyers — circulated after the release of a December 2025 enterprise AI report. Staff reviewed 12 primary sources, with that report as the anchor document, to test whether the headline matched the evidence.

What the sources support

The reviewed material corroborates the central motion of the claim. The report's enterprise figures document OpenAI gaining ground in the corporate segment, a shift large enough to be consistent with the reversal narrative. Read narrowly, the core of the claim has support: OpenAI's enterprise position is no longer what it was.

Where it falls short

The single word "reversal," however, implies a completed, across-the-board overtaking of the enterprise AI market. The reviewed record supports a narrower conclusion. The enterprise market is not uniform, and the standings look different depending on the segment examined and the yardstick used to measure share. Taken as a blanket statement covering the entire corporate market, the claim outruns the evidence in the sources.

Why it matters for Korean buyers

For Korean enterprises and public agencies weighing multiyear LLM commitments, the distinction is practical rather than academic. Vendor positions in the enterprise AI market are moving quickly, and headline claims of a finished reversal can flatten segment-level differences that procurement teams need to see before locking in a vendor. The safer reading of the December 2025 report is directional: OpenAI is gaining in the enterprise market, while the overall picture remains mixed by segment.

Judged against the 12 primary sources reviewed, the claim that OpenAI has reversed enterprise market share is Partly True.
