Once a model achieves product-market fit, retention improves significantly. But stickiness is rare, churn is the norm, most models lose 60-70% of users within the first month.

Role-playing is the fast-growing consumer use case. DeepSeek dominates here, with 80% of its volume in roleplay. Cost sensitivity drives this segment, so consumers won’t pay enterprise prices for entertainment.

Third, coding has found product-market fit. Programming accounts for 60% of Anthropic’s usage & 45% of xAI’s, both heavily skewed toward developer workflows.
The table below shows the top 2 use cases by provider (November 2025). Technology refers to AI assistant tasks like research & summarization.

Second, the distribution of open-source models has shifted dramatically. DeepSeek held nearly 80% of OSS market share in early 2025, but has dropped to 40% as Qwen & other Chinese models have gained ground.

The weak price elasticity indicates that even drastic cost differences do not fully shift demand; proprietary providers retain pricing power for mission-critical applications, while open ecosystems absorb volume from cost-sensitive users.

Over the last year, open-source models’ market share has remained stable around 22-25%, briefly spiking to 35% during the explosive growth of Chinese models in mid-2025 before settling back down.

Microsoft contributes equity to the partnership, gets AI infrastructure exposure, but the debt doesn’t appear in Microsoft’s 10-K. This is why Microsoft remains “the only hyperscaler not tapping debt markets recently” for direct corporate bond issuance.

With this deal, BlackRock GIP + Microsoft now matches Blackstone as the largest data center acquirer, each with ~$40B in total deal value since 2021.
Why this structure matters : The 70% debt leverage sits at the fund level, not on Microsoft’s corporate balance sheet.
