ByteDance is rushing to sell a 20% stake in TikTok Global to Oracle and Walmart at an enterprise value of $60 billion. TikTok otherwise faces a ban in the US on 12 November, subject to legal challenges.

The sale hinges on ByteDance obtaining approval from China to export TikTok’s core technologies. China updated its export control rules to include algorithms (and AI), entrenching a tech cold war with the West.

TikTok has confounded regulatory woes in India and the US, and renewed competition from US tech, to post dizzying user growth in every major internet region where it is available, casting off its image as a niche youth product and entering the mainstream.

Press reports suggest that the restrictions on Huawei equipment may morph into a full ban, with new installations stopping soon and existing equipment to be removed by 2029.

The direct ‘tear-out’ and replacement costs for mobile would be very high at up to £2bn, and there would be significant disruption to 5G roll-outs as operators’ focus moves to replacing what they already have as opposed to pushing into new coverage areas.

Previous rules applied to fixed line broadband networks with as much force as mobile; having to replace Huawei broadband kit would almost certainly delay the move to ‘full fibre’, for no good reason even according to the government’s own report.
