Retail media in Southeast Asia matures past the experimentation phase

Retail media across Southeast Asia has moved out of pilot phase. Most major grocery and marketplace operators now run structured offsite and onsite inventory, and supplier participation has become close to obligatory in negotiated trade terms.

The bottleneck has shifted. Inventory is plentiful; comparable measurement is not. Suppliers running campaigns across three or four retail networks receive incompatible attribution windows and incrementality definitions, which makes budget allocation a matter of negotiation rather than analysis.

What changes next

Pressure for standardisation is coming from the largest advertisers rather than the platforms. Where a supplier can credibly threaten to concentrate spend, retailers have begun to concede on measurement transparency.
