I have no insider knowledge, however, my guess is that since the last 2 "big deals" involved AI, they will look for another opportunity to talk about AI.
Possibilities include (this is my opinion):
Google AI tie-in (however Google has their own fiber network and likes to own everything, so they may not want to admit to using Lumen)
IBM - is an also-ran at this point, but might do a joint press release
Oracle Cloud - Oracle bought a very large number of GPUs
since Starlink is a competing technology that directly targets mass-market Quantum Fiber, I wouldn't expect a tie-in with them ; I wouldn't expect any of the Elon Musk companies to work much with Lumen
Any other ideas? I suppose a tie-in with a consulting company like Accenture, McKinsey or BCG might be possible, but would be seen by many as being second-tier.
