Sovereignty on Someone Else's Weights

​A working roundtable for technology and risk leaders in banking, insurance, healthcare and retail. Roughly 40% of the world's sovereign LLM programmes run on one American company's published weights. Open-weight models now carry 36% of production token volume but only 8.6% of spend - developers have switched, procurement has not. Omar Arias, founder and CEO of Estratek and a former insurance CEO, opens with twenty minutes of framing, followed by open discussion: which decisions can live where, the break-even maths of self-hosting, and what sovereignty really buys a regulated institution. Non-commercial, no vendor pitch, Chatham House rule. An official World AI Week affiliated event.
