In its Q3 FY2026 earnings ($82.9B revenue, +18%), Microsoft revealed a structural shift from per-seat licensing to a hybrid per-seat + consumption model where agents are billed alongside human users. The company's AI business crossed $37B annual run rate, up 123% YoY. Ben Thompson's Stratechery analysis frames this as Microsoft's most significant business model evolution since the cloud transition — productivity software now priced by 'seat or worker plus an agent.'
