Jakarta's golden share in a Southeast Asian superapp would set a dangerous precedent for state power, say researchers. SYDNEY: Speculation is mounting over a potential merger between Southeast Asia’s two largest superapps – Indonesia’s GoTo, listed on the Indonesia Stock Exchange, and Singapore’s Grab Holdings, listed on the Nasdaq in the United States. If approved, the combined entity could control up to 91 per cent of Indonesia’s ride-hailing market. This consolidation makes commercial sense.
