Summary

OpenAI is currently limiting access to its GPT-5.6 models to a select government-approved group, following security discussions with the Trump administration. While OpenAI expressed disagreement with the White House's increasing restrictions on national security grounds, it anticipates making GPT-5.6 generally available in the coming weeks. This follows a similar two-week ban on foreign access to two models from rival Anthropic due to comparable security concerns. Separately, two senators, John Curtis and Adam Schiff, have urged the Commodity Futures Trading Commission (CFTC) to investigate Polymarket for deceptive advertising practices, after a Journal investigation uncovered payments to creators for staged trades on fake websites and viral video promotion. The CFTC, which previously dropped a probe, is reportedly conducting a continuing investigation. Additionally, President Trump threatened 100% tariffs on European nations, including France, Denmark, and Portugal, if they implement new digital services taxes targeting American tech companies, potentially superseding a prior EU trade pact.

Key takeaway

For investors monitoring regulatory risks and international trade, be aware that government scrutiny of AI models is intensifying, potentially impacting market availability and company valuations. The ongoing CFTC investigation into Polymarket highlights increased regulatory focus on advertising integrity in emerging markets. Furthermore, President Trump's threat of 100% tariffs on European digital services taxes signals significant trade policy volatility, which could affect tech company revenues and international market access. You should factor these evolving regulatory and trade dynamics into your portfolio risk assessments.
