Southeast Asia E-Commerce

Shopee's 52% regional GMV share in 2024 — up from 48% in 2023 — translates to approximately US$66.8 billion in absolute GMV. [Momentum Works] That four-point share gain in a single year, achieved while the total market was growing 12%, means Shopee added volume faster than the market expanded. This is not holding a lead — it is extending one.

The TikTok Shop and Tokopedia combination, created after ByteDance acquired 75% of Tokopedia in December 2023, holds approximately 27.5% combined regional share, or roughly US$35.4 billion GMV. [Momentum Works] The merger gave TikTok Shop an Indonesian marketplace licence and local logistics infrastructure — solving the regulatory problem that led Indonesia to ban social commerce on TikTok alone in late 2023. But the combined entity still trails Shopee by more than US$31 billion in GMV, and the gap in absolute terms widened in 2024 despite the merger.

Lazada, Alibaba's regional flagship, holds 14% share and has declined for three consecutive years. [Momentum Works] Alibaba has not publicly disclosed Lazada's revenue or GMV targets, but the sustained share loss — in a market growing at 12% annually — signals structural underperformance, not a cyclical dip. The platform question in SEA has effectively been answered at the regional level: Shopee won. The competitive contest now plays out country-by-country and category-by-category.

The country-level data reveals a market that looks very different from the regional aggregate. Vietnam (65% Shopee share), Malaysia (62%), Singapore (56%), Philippines (52%), and Thailand (51%) are effectively Shopee-dominant markets. [Momentum Works] In these five countries, the top three platforms — Shopee, Lazada, and TikTok Shop — collectively hold more than 90% of GMV, leaving almost no oxygen for new entrants.

Indonesia is the exception. Shopee holds 46% share there, with Tokopedia at 23% and TikTok Shop at 11% — giving the TikTok Shop/Tokopedia combined entity roughly 34% in Indonesia's largest single market. [Momentum Works] Indonesia is not just the biggest market by GMV; it is the only country where the competitive outcome is still being determined. That makes it the highest-stakes battleground in the region, and the place where capital allocation and regulatory decisions will matter most through 2026 and beyond.

Malaysia and Thailand are both posting double-digit GMV growth despite Shopee's dominance, suggesting category expansion rather than platform switching is driving new volume. [Momentum Works] Singapore, the most mature market, is growing more slowly but produces the highest average transaction values — and is the only market where Amazon competes meaningfully through Amazon.sg.

Quick-commerce groceries — defined as delivery under 30 minutes — are growing at 45–55% per year across the region and are projected to reach US$15–18 billion GMV by 2025, up from US$5 billion in 2023. [Google-Temasek-Bain] Indonesia and Vietnam account for roughly 60% of that volume. The growth is structural: urban density in Jakarta, Ho Chi Minh City, and Manila makes fast delivery economically viable, and digital payment adoption (over 70% in the region per Bain's 2025 Outlook) removes the cash-on-delivery friction that slowed grocery e-commerce for years. [Bain]

Fashion is the second-fastest-growing category at 25–30% annually, and it is being driven almost entirely by live-streaming and social commerce. TikTok Shop's model — in which sellers demonstrate products live to audiences who can purchase in the same session — has unlocked a purchase trigger that static product listings could not. Bain's 2025 Outlook estimates that social commerce accounts for 20–25% of total regional GMV, with live-streaming growing at triple-digit rates in Indonesia, Vietnam, and the Philippines between 2022 and 2024. [Bain]

Electronics, which built SEA e-commerce's early GMV base, is slowing. Growth is estimated at 18–22% annually — still strong in absolute terms but decelerating as Singapore (45–50% online penetration for electronics, approaching saturation per Singapore's Department of Statistics) and Malaysia (25–30% penetration) reach diminishing returns. [SingStat] The implication is clear: platforms prioritised electronics-led GMV will need to execute a category transition, or watch their growth rates fall below the market average.

Shopee's e-commerce EBITDA margin was 0.7% of GMV for full-year 2025, up from earlier quarters where it reached a high of 0.8% in Q2 2025 before slipping to 0.6% in Q3 and 0.55% in Q4. [Sea Ltd Earnings] Management has guided to a long-term target of 2–3% EBITDA margin on GMV — a level that would require roughly tripling or quadrupling the current margin. The FY2026 analyst model sits at 0.9%. [DBS] At current GMV scale, the difference between 0.7% and 2% margins is approximately US$1.6 billion in annual earnings.

The margin pressure comes from two directions simultaneously. Logistics subsidies suppressed value-added services revenue: that segment fell 6% year-on-year to US$724 million in Q3 2025 alone as Shopee subsidised shipping to defend share. [Sea Ltd Earnings] On the revenue side, advertising is the margin driver — ad take rates grew more than 80 basis points year-on-year in 2025, and ad revenue grew over 70% — but advertising revenue alone cannot offset the cost of running SPX Express, which handled 24.5% of SEA e-commerce logistics in 2024. [Sea Ltd Earnings]

SeaMoney, Sea Limited's financial services segment, is the group's most profitable business: FY2025 revenue reached approximately US$4 billion, up 26% year-on-year, with adjusted EBITDA margins of 56.1%. [Sea Ltd Earnings] This matters because SeaMoney effectively subsidises the e-commerce and logistics investment — and the payment ecosystem creates lock-in that pure marketplace revenue cannot. Platforms without an embedded payments layer are structurally disadvantaged in this market.

Southeast Asia's e-commerce growth in 2025 is concentrated among consumers under 35, particularly urban middle-class buyers in Indonesia, Vietnam, and the Philippines who are using smartphones as their primary — often only — shopping interface. [Google-Temasek-Bain] Indonesia accounts for 28% of regional e-commerce market share by volume and is home to the largest pool of first-time digital buyers, many of whom enter through social platforms rather than traditional marketplaces. The urban-rural split is meaningful: penetration in major cities (Jakarta, Ho Chi Minh City, Manila) is multiples higher than national averages, and the growth opportunity in secondary cities and rural areas is the next wave — not the current one.

Live-streaming commerce is the most important new purchase mechanism in the region. Bain estimates that social commerce accounts for 20–25% of total regional GMV, and that live-streaming drove triple-digit GMV growth on TikTok Shop in Indonesia, Vietnam, and the Philippines between 2022 and 2024. [Bain] The mechanism is not just discovery — it compresses the entire purchase funnel into a single session. A buyer watching a live-stream can see the product demonstrated, ask questions, receive a time-limited offer, and complete purchase without leaving the app. That compression produces conversion rates significantly above static listings, which is why fashion and beauty — high-consideration, visually demonstrable categories — are the primary beneficiaries.

Embedded fintech is the other loyalty mechanism. Buy-now-pay-later (BNPL) and digital wallets increase conversion among price-sensitive buyers who cannot or will not commit to a full purchase price upfront. [Bain] Shopee's integration with ShopeePay and SeaMoney, Grab's GrabPay ecosystem, and GCash in the Philippines each create payment-layer lock-in that is more durable than discount-based loyalty. Buyers who use a platform's payment product are less likely to switch — not out of preference, but because moving payment history and wallet balances is a real friction cost.

Indonesia's ban on social commerce in 2023 — which required TikTok Shop to cease standalone operations until it partnered with a licensed local marketplace — is the defining regulatory event in SEA e-commerce over the past three years. The operational response was ByteDance acquiring 75% of Tokopedia for approximately US$1.5 billion, giving TikTok Shop a local marketplace licence and Indonesian logistics infrastructure. [Momentum Works] That is not a workaround — it is a full market restructuring forced by a single regulatory decision.

Indonesia's broader regulatory posture on foreign ownership in e-commerce is governed by BKPM rules that cap foreign ownership at 49% in certain retail categories. [Bain] This structural constraint means foreign platforms building in Indonesia must either find local partners or accept capped ownership — a friction cost that does not exist in Singapore or Malaysia.

ASEAN's Strategic Plan 2026–2030 commits member states to creating a more connected digital economy and reducing barriers to intra-ASEAN trade. [ASEAN] But implementation is country-level, and the six markets in this report have materially different timelines. Indonesia's OJK Regulation 40/2024 tightened P2P lending oversight with minimum capital requirements and foreign ownership caps. Bank Indonesia's Governor Regulation 3/2025 (effective February 2025) explicitly permits cross-border digital payments through QRIS — which is a tailwind for e-commerce payment infrastructure, not a restriction. [OJK] The net regulatory picture in Indonesia is: payments are opening up, marketplace ownership is constrained, and social commerce without local infrastructure is not permitted.

The incumbent platforms in SEA e-commerce benefit from a structural position that is genuinely hard to displace. Shopee's combination of marketplace GMV scale, SPX Express logistics (24.5% of SEA e-commerce logistics in 2024), and SeaMoney payments creates three interlocking moats. [Sea Ltd Earnings] A new entrant would need to build or partner all three simultaneously to compete at the national level — a capital and time requirement that most actors cannot meet.

Supplier bargaining power — sellers on these platforms — is declining as seller concentration on Shopee and TikTok Shop increases. With Shopee commanding more than 50% share in five markets, a small or mid-size seller in Vietnam or Malaysia has limited viable alternatives. That asymmetry gives platforms pricing power on commission rates and advertising fees, which is exactly what Shopee's 80-basis-point increase in ad take rate in 2025 reflects. [Sea Ltd Earnings]

The new entrant threat comes primarily from Chinese cross-border platforms — Temu and Shein both operate in the region — and from vertical specialists targeting specific categories like groceries or fashion. However, regulatory restrictions on foreign ownership in Indonesia, combined with the logistics investment required to compete on delivery speed, keep the practical threat at medium rather than high. No new entrant has demonstrated the ability to capture meaningful GMV share from Shopee at the regional level.

The base case — a 55% probability — is that Shopee consolidates its lead, TikTok Shop and Tokopedia grow their combined share incrementally in Indonesia and Vietnam, and Lazada continues declining without a major operational turnaround or Alibaba capital injection. Regional GMV reaches US$155 billion by 2026 and US$200 billion by 2028, driven by category expansion in groceries, fashion, and beauty rather than new buyer acquisition at scale. Shopee's EBITDA margin improves toward 1–1.5% of GMV as advertising take rates rise and logistics subsidies are partially withdrawn.

The bull case — a 25% probability — requires that quick-commerce groceries expand faster than projected, that digital payment adoption in rural Indonesia and the Philippines accelerates, and that live-streaming commerce drives a step-change in fashion and beauty GMV. In this scenario, the total market could reach US$200 billion by 2026 — two years ahead of the base case timeline — and Shopee's ad revenue becomes a genuinely high-margin business line. The trigger to watch is rural smartphone penetration and logistics network expansion in the Philippine islands and eastern Indonesia.

The bear case — a 20% probability — is regulatory fracture: Indonesia introduces additional restrictions on foreign-linked platforms (which would affect TikTok Shop/Tokopedia and potentially Shopee itself given Sea Limited's Singapore-Cayman structure), macro deterioration reduces consumer spending in the Philippines and Vietnam, or a Chinese cross-border platform enters at scale with subsidy-funded pricing that margin-pressures the incumbents. In this scenario, GMV growth decelerates to 6–8% annually and margin improvement stalls entirely.
