Key takeaways

• OpenAI launched GPT-5.6 with three tiers (Sol, Terra, Luna) explicitly benchmarked to outperform Anthropic's models on coding tasks at lower cost and latency, signaling an intensifying enterprise AI rivalry.
• The EU Commission issued preliminary findings that Meta's infinite scroll and autoplay features violate the Digital Services Act, potentially forcing structural product design changes under threat of fines up to 6% of global revenue.
• SK Hynix raised $26.5B in the largest-ever US market debut by a foreign company, reflecting surging institutional demand for AI memory infrastructure as HBM supply remains constrained.

Why this matters

The convergence of OpenAI's aggressive enterprise pricing strategy, EU regulatory pressure on platform design, and record capital flows into AI memory hardware signals that AI infrastructure competition is rapidly reshaping both product strategy and regulatory risk for B2B technology buyers and investors.
