Through 2027, new studio and agency engagements will shift measurably toward fixed-scope, fixed-price structures, with open-ended monthly retainers becoming the minority model for new client relationships in brand and product work.
What remains scarce is judgement about which output is worth producing — a scoped, conclusion-based deliverable, not a monthly seat.
The falsifier: if new-engagement data shows retainer structures stable or growing as a proportion of new studio contracts, or clients broadly return to retainers because fixed-scope AI-era work proves too hard to estimate, this call is wrong.
Why we think it resolves hit: AI reduced the cost of producing creative and technical output, which makes the retainer’s implicit pitch — pay for access, get continuous output — worth less to a buyer who can generate output cheaply elsewhere.
Highlights
Fixed-scope, fixed-price structures should overtake open-ended retainers for new engagements by 2027.
Falsifier: retainer share holding stable or growing across new studio contracts.
Ongoing operational work keeps a retainer logic — only judgement-heavy work is expected to move.
