SK Telecom Prompt Competition: AI Co-Creation as CX Strategy

What happened

South Korean telecoms operator SK Telecom (SKT) has launched a public prompt-writing competition as a centrepiece of a broader campaign linking artificial intelligence capability to customer engagement. The initiative invites customers to submit prompts — structured instructions used to direct AI models — with the competition serving as both a marketing activation and a mechanism for gathering real-world, customer-generated AI use cases.

The campaign positions SKT's AI ambitions not as a back-office efficiency story but as something customers can participate in directly, turning prompt engineering — until recently the preserve of developers — into a consumer-facing activity.

Why it matters

Telecoms operators globally are under pressure to demonstrate that their AI investments translate into tangible customer value rather than internal cost savings alone. SKT's approach is notable because it externalises the AI development loop: instead of building AI products in isolation and pushing them to market, the carrier is co-opting customers as contributors. From a behavioural-economics standpoint, this is a deliberate application of the IKEA effect — people assign greater value to products and services they have had a hand in creating. By asking customers to write prompts, SKT increases psychological ownership of the resulting AI experience before the product is even fully defined.

For service designers, the competition format also functions as structured ethnographic research at scale. Every submitted prompt is a signal about what customers actually want AI to do for them — far richer data than a survey, and gathered at near-zero marginal cost. Operators and brands in any sector considering AI-led service transformation should take note: participation mechanics can double as discovery research.

The Renascence take

Most coverage of this campaign will treat it as a marketing stunt. That reading misses the more consequential dynamic underneath.

What SKT is really doing is outsourcing the hardest part of AI product design — understanding genuine customer intent — to the customers themselves, and rewarding them for it. The prompt competition is not a gimmick; it is a behavioural data-collection engine dressed as engagement. The lesson for customer-obsessed operators is straightforward: before you build another AI feature based on internal assumptions, design a participation mechanic that makes customers show you what they need. Co-creation at this stage is cheaper, faster and more accurate than any focus group — and it builds the emotional investment that drives adoption once the product ships.
