This isn't quite the framing I'd use—the key thing that would make it make sense for the deal to go this way is if there's competition bidding for the slot. Say OpenAI also wants in and was willing to pay for it. Absent competition for the slot and assuming that Telegram actually wanted the deal, we'd expect to see at most a no-cost exchange.

There's no reason for Grok to pay this much for the deal unless either Telegram sees it as a net negative that needs reimbursement or they're competing with other bids.
