Apple has filed a lawsuit against OpenAI, alleging that the AI company and two former Apple employees stole trade secrets related to unreleased AI hardware. The legal action, filed in the U.S. District Court for the Northern District of California, has heightened tensions between the two companies, which previously partnered to integrate ChatGPT into iOS devices. This lawsuit comes amid ongoing antitrust litigation involving both firms and X Corp. Markets appear to interpret this lawsuit as a potential increase in competition and regulatory scrutiny in the tech sector.

In prediction markets, the news seems to have influenced sentiment regarding the standing of major tech companies. The likelihood of Alphabet being the second-largest company by market cap on July 31, 2026, has decreased, with the market pricing this scenario at 23% YES, down from 29% 24 hours ago. This suggests that market participants may view the lawsuit as a factor that could negatively impact Alphabet’s stock performance, possibly due to broader concerns about competition or regulatory issues within the tech industry.

Meanwhile, markets tracking OpenAI’s future valuation appear less affected, though the legal confrontation with Apple could introduce uncertainties. The market suggests a 24% probability that OpenAI’s valuation will reach $1.5 trillion by December 31, 2026, reflecting a relatively stable outlook despite the lawsuit’s potential implications.
