Million-token context windows in production use at Fortune 500 companies

Context windows have expanded rapidly, but production deployment at enterprise scale faces latency, cost, and reliability barriers that benchmarks do not capture.

RESOLUTION CRITERIA

True if 3+ Fortune 500 companies publicly report using AI systems with 500K+ token context windows in production workflows. Public statements, case studies, or earnings call references qualify.

▲ FOR

151 days remaining provides runway

Gemini 4 Carbon highlights long-horizon task capability — if/when released broadly, could enable Fortune 500 million-token production use

UBS 608 live AI use cases confirms Fortune 500 enterprise AI production depth

▼ AGAINST

UBS agent deployment describes coding tools and general productivity — no million-token context use case implied or named

ISG finding of bounded-task agent deployment pattern is inconsistent with million-token context use cases which require complex, long-horizon reasoning tasks

No named Fortune 500 company confirmed using million-token contexts specifically in 14+ consecutive cycles — structural absence dominant

Gemini 4 Carbon restricted to cybersecurity teams — no general Fortune 500 production access signal

HIGH time pressure: 151 days with naming criterion unaddressed
