程维王兴，旧敌新局

Core Viewpoint - Rappi has formally joined the lawsuit against 99Food, accusing it of imposing exclusivity clauses in contracts with restaurants, which restricts competition in Brazil's food delivery market [1][25]. Group 1: Market Dynamics - The Brazilian food delivery market is currently dominated by iFood, which holds over 80% market share, effectively creating a monopoly [10][15]. - The market size of Brazil's food delivery sector is approximately $12 billion, with an expected annual growth rate of 20%, potentially making it the fourth largest food delivery market globally [8]. - Didi's 99Food has been accused of signing exclusivity agreements with restaurants, limiting their ability to partner with competitors like Meituan's Keeta, which has not yet launched in Brazil [2][6][29]. Group 2: Competitive Landscape - Didi's strategy involves categorizing competitors into tiers, with iFood being the most dominant, followed by Rappi, and then Meituan's Keeta, which is still in the pilot phase [3][4][5]. - Rappi's market share is currently in the single digits, making it less impactful in negotiations with restaurants compared to iFood [27]. - Didi's renewed focus on 99Food indicates a strategic shift, as the company aims to capitalize on the regulatory environment that limits iFood's monopolistic practices [18][21]. Group 3: Regulatory Environment - Brazil's antitrust agency, CADE, has imposed certain restrictions on iFood regarding exclusivity agreements, but these do not completely eliminate such practices [20]. - The legal actions taken by Rappi and Keeta against 99Food highlight the ongoing competitive tensions and regulatory challenges in the Brazilian market [19][29]. - Didi's approach to exclusivity agreements reflects a broader trend of leveraging financial investments to secure market position, similar to strategies employed by Meituan in other regions [23][28].
