A San Francisco jury on June 10, 2026, convicted Wynd Sethe Kaufmyn, 68, on all four misdemeanor counts arising from a February 2025 demonstration that blocked access to OpenAI's San Francisco headquarters [1]. The People charged Kaufmyn with interfering with a business, trespassing with intent to interfere with a business, unlawful assembly, and refusal to disburse at a riot [1]. Kaufmyn was among demonstrators affiliated with the "STOP AI" protest group, which physically obstructed the company's offices during the action [1]. The case proceeded in San Francisco Superior Court before a jury, marking the first known conviction stemming from that protest movement [1].
At trial, prosecutors pressed each of the four counts through to verdict without a hung count or acquittal [1]. The jury returned convictions on all charges, resolving the factual disputes, including whether Kaufmyn's presence and conduct satisfied the elements of unlawful assembly and the refusal-to-disburse count, against the defense [1]. The case drew attention because it tests the boundary between constitutionally protected protest activity and criminal interference with private business operations, a line that California courts have revisited as demonstration tactics have grown more disruptive.
Sentencing is scheduled for June 22, 2026, in San Francisco Superior Court [1]. Because the charges are misdemeanors, the sentencing exposure is limited under California law, though the court retains discretion to impose fines, probation, or a custodial term. No post-trial motions or immediate notice of appeal was reported in available sources as of the verdict date.
