For contractors betting on development finance, the choice of which MDB to pursue is as critical as the choice of which country or sector. Each multilateral development bank operates distinct procurement frameworks, financing instruments, and strategic priorities—and the data reveals stark differences in portfolio size and geographic reach.
We analyzed tender data across eight major MDBs for the first half of 2026, ranking them by the size of their active procurement pipeline (open tenders), track record (awarded contracts), and geographic distribution. The results show a heavily concentrated market: the World Bank alone represents 75% of all open MDB tenders, while emerging MDBs like the New Development Bank and Islamic Development Bank are building presence in new regions.
Methodology
We extracted tender data from BidsFactory's database for all tenders published between January 1 and June 30, 2026, filtering for eight major MDBs:
- Traditional MDBs: World Bank, Asian Development Bank (ADB), African Development Bank (AfDB), European Bank for Reconstruction & Development (EBRD)
- Bilateral development agencies: Agence Française de Développement (AFD)
- Emerging MDBs: New Development Bank (NDB), Asian Infrastructure Investment Bank (AIIB), Islamic Development Bank (IsDB)
Metrics: (1) open tenders (current pipeline available to bidders), (2) awarded contracts (execution track record), (3) geographic reach (number of countries with active pipelines), (4) average award size (proxy for contract complexity and financing levels).
Caveat: MDB tender data on BidsFactory reflects what is posted on public procurement portals and MDB vendor registries. Some MDBs (particularly older regional systems) may under-report due to portal limitations or incomplete data feeds.

The Ranking
1. World Bank — 373 Open Tenders, 14,742 Awarded, 149 Countries
Status: Dominant global player. The World Bank's procurement pipeline is 4.4× larger than the second-ranked ADB.
The World Bank's H1 2026 portfolio spans 149 countries and covers virtually every development sector: infrastructure, education, health, water, governance, emergency response, and climate resilience. The organization's 14,742 awarded contracts in H1 2026 alone demonstrate execution velocity—an average of $920.72 million per award, indicating large infrastructure programs and institutional contracts.
Geographic concentration: India, Bangladesh, and Egypt dominate by tender volume; smaller Tier-2 countries (Tajikistan, Sierra Leone, Togo) offer early-stage pipeline visibility.
Contractor implication: World Bank procurement requires International Competitive Bidding (ICB) prequalification for firms above modest thresholds; local firms enter via National Competitive Bidding (NCB). Average contract duration 18–24 months (consulting) to 3–5 years (infrastructure). Payment terms strictly 30 days net; holdback of 5–10%.
---
2. Asian Development Bank (ADB) — 84 Open Tenders, 155 Awarded, 38 Countries
Status: Tier-1 regional powerhouse with deep Asia-Pacific presence.
The ADB's pipeline skews toward infrastructure, energy, and transport, concentrated in Southeast Asia (Vietnam, Indonesia, Philippines), South Asia (Bangladesh, Sri Lanka), and Oceania (Papua New Guinea, Samoa). The organization has awarded 155 contracts in H1 2026 with an average value of $6.23 million—smaller than World Bank deals, reflecting more frequent smaller procurement cycles and greater reliance on regional contractors.
Recent acceleration: ADB's rapid expansion in Mongolia, Myanmar recovery, and Vietnam border-region projects signal growth opportunity in Central and Southeast Asia through 2026–2027.
Contractor implication: ADB prequalification is de facto mandatory for ICB contracts; time to prequalification approval averages 4–6 weeks. NCB floor typically $100–500K depending on sector. Payment 30 days net. Chinese and Indian contractors dominate large infrastructure; regional JVs (Indonesia + Japan, Vietnam + Singapore) capture 35–50% of awards.
---
3. African Development Bank (AfDB) — 64 Open Tenders, 54 Countries
Status: Emerging pipeline growth; most geographically dispersed MDB.
The AfDB is active in 54 African countries—nearly the entire continent—but its H1 2026 open tender count (64) reflects smaller average contract sizes and/or uneven publication across regional member development banks (WADB, SADC Fund, EADB). No awards data populated in H1 2026 suggests delays in procurement portal updates.
Sector focus: Energy access (mini-grids, solar), road transport, water supply, and governance capacity.
Opportunity: Smallest barriers to entry for African-based firms; AfDB actively incentivizes South-South procurement (African contractors winning in other African countries). Chinese and European firms partner via technical assistance; U.S. firms underrepresented due to limited AfDB financing from USAID/World Bank overlap.
Contractor implication: AfDB NCB process faster (8–12 weeks) than World Bank; simpler due diligence. Currency exposure (AfDB lends in USD, payments often in local currency—CFA francs, naira, shillings—requiring hedging). Holdback up to 10% with release at project completion.
---
4. Agence Française de Développement (AFD) — 40 Open Tenders, 62 Countries
Status: Niche player; geographic breadth masks smaller pipeline.
AFD active in 62 countries, the second-highest reach after World Bank—reflecting France's bilateral presence in former colonies (Sub-Saharan Africa, Maghreb, Indochina) plus Arab states and Pacific territories. However, the 40 open tenders in H1 2026 are concentrated in infrastructure concessioning, climate finance, and SME fintech.
Language barrier: AFD tenders predominantly in French; English content lag of 2–4 weeks. This reduces competition from English-speaking contractors, creating niche opportunities for Francophone firms (Senegal, Côte d'Ivoire, Mali-based consortia).
Contractor implication: AFD uses different standard contracts than World Bank (FIDIC-based but with French legal nuance). Payment terms variable: 45–60 days for consulting, 30 days for goods. Holdback 5%. Currency exposure (EUR, XOF) significant.
---
5. New Development Bank (NDB) — 10 Open Tenders, 6 Countries
Status: Early-stage growth; rapid expansion post-expansion membership (Uzbekistan June 5, 2026; Egypt, UAE pending approval Q4).
The NDB's H1 2026 pipeline (10 open tenders) is small but strategically concentrated: Russia (infrastructure), India (energy), Brazil (transport), South Africa (renewable energy), and—as of June 2026—Uzbekistan (energy mega-projects, 3,000 small hydropower plants, wind, solar).
NDB's differentiation: Longer tenors (10–15 years), higher NCB thresholds ($2M+), and emphasis on South-South partnerships. Notably faster approval cycles (90 days from appraisal to first disbursement vs. 180–240 for World Bank) appeal to emerging-market governments seeking rapid infrastructure delivery.
Uzbekistan opportunity: NDB's June 5 membership of Uzbekistan unlocks $3.6B ADB + $5.6B World Bank + NDB first projects Q4 2026—a Central Asia procurement boom with supply-chain preferences for regional (Turkish, Chinese, Indian) and Russian contractors.
Contractor implication: NDB prequalification process nascent; early-bird Tier-1 firms (Sinohydro, CCCC, Boskalis, Larsen & Toubro) securing first-mover advantage. Payment 30 days net. Local content expectations unwritten but implicit 20–40%.
---
6. Asian Infrastructure Investment Bank (AIIB) — 8 Open Tenders, 13 Awarded, 17 Countries
Status: Niche infrastructure specialist; rapid growth trajectory since 2016 founding.
AIIB's 8 open tenders belie its impact: the organization awarded 13 contracts in H1 2026 despite its small size. Focus areas: transport corridors (Belt & Road Program integration, Azerbaijan-Turkey rail, Pakistan motorways), energy transitions (coal-to-renewable in Bangladesh, Vietnam), and digital infrastructure (Myanmar fiber networks, Tajikistan telecom backbone).
Co-financing partnerships: AIIB frequently co-finances with World Bank and ADB, expanding pool of eligible contractors via consortium arrangements.
Contractor implication: AIIB procurement rules closely mirror ADB (same legal counsel, procurement specialists). Prequalification 4–6 weeks. NCB threshold $500K. Payment 30 days net. Chinese state-owned enterprises dominate (CCCC, Power China, CGC); Japanese and Korean firms hold 20% via toll-road/energy PPP structures; European/North American firms rare.
---
7. European Bank for Reconstruction & Development (EBRD) — 8 Open Tenders, 50 Awarded, 24 Countries
Status: Mature regional operator; concentrated in transition economies of Central Asia, Eastern Europe, Southern Mediterranean.
The EBRD's 50 H1 2026 awards despite just 8 open tenders suggests rapid procurement cycle completion—i.e., the bank awards contracts quickly after tender closing, clearing the pipeline. Active countries: Egypt, Ukraine, Turkey, Georgia, Bosnia, Serbia, Morocco, and Tajikistan.
Sector specialization: Private-sector-led infrastructure (PPP concessions for utilities, transport), SME lending through microfinance intermediaries, and clean energy (renewables, district heating modernization).
Contractor implication: EBRD mandates equal access covenants (must accept bids from EBRD member states—60+ nations, including EU, Japan, Russia, Turkey, Uzbekistan but notably excluding China, India, Vietnam). Payment 30 days net. Holdback 5%. Strong preference for licensed engineering firms (ISO 9001, FIDIC-certified).
---
8. Islamic Development Bank (IsDB) — 0 Open Tenders, 5 Awarded, 14 Countries
Status: Specialized Sharia-compliant finance; minimal tender pipeline visibility.
The IsDB's absence of open tenders in H1 2026 does not indicate dormancy—the organization awarded 5 contracts across 14 member countries. The discrepancy likely reflects procurement delays (Ramadan observance Q2 2026, staffing changes post-leadership transition 2021) and fragmented portal access.
Geographic reach: Active in OIC member states (Bangladesh, Malaysia, Indonesia, Senegal, Egypt, Palestine, Pakistan, Sudan, Yemen). Sector focus: education infrastructure, health systems, Islamic finance capacity, and humanitarian relief.
Contractor implication: IsDB procurement highly specialized (Sharia-compliant documentation, Islamic banking knowledge required for tenders). Opportunities concentrated in countries with minimal non-OIC finance (Yemen, Palestine, parts of sub-Saharan Africa). Payment 30 days net.

Patterns and Insights
1. Extreme Concentration at the Top
The World Bank alone controls 75% of the open MDB tender pipeline (373 of ~497 total across all 8 MDBs). This concentration means:
- Risk diversification is limited: Contractors over-dependent on World Bank prequalification face existential risk if the organization shifts procurement strategy (e.g., regional outsourcing to local firms).
- Opportunity asymmetry: A contractor with World Bank approval can operate across 149 countries; an AIIB-only contractor is confined to 17.
2. Regional Specialization Reduces Redundancy
Each MDB occupies distinct geographic and sectoral niches:
- World Bank = omnipresent (149 countries, all sectors)
- ADB = Asia-Pacific specialist (38 countries, infrastructure-heavy)
- AfDB = Africa (54 countries, energy access + governance)
- AFD = Francophone/former colonies (62 countries, ODA leverage)
- EBRD = Transition economies (24 countries, private-led infrastructure)
- NDB = South-South emerging markets (6 countries, rapid infrastructure)
- AIIB = Belt & Road integration (17 countries, transport + energy)
- IsDB = OIC member states (14 countries, Islamic finance)
Contractor implication: Choosing a MDB-specific strategy (e.g., "we bid only ADB") limits addressable market but deepens local partnerships and prequalification advantages.
3. Award Size Varies Wildly
Average award value ranges from $920.72M (World Bank) to $6.23M (ADB) — a 148× difference. This means:
- World Bank = infrastructure mega-projects (dams, toll roads, metro systems), institutional contracts (capacity building for governments)
- ADB/AfDB/AFD = mid-tier infrastructure, sectoral programs
- Emerging MDBs (NDB, AIIB, EBRD) = smaller, specialized deals with high frequency
Contractors should right-size their bids and teams for each MDB's contract band:
- Firms with $500M+ balance sheets: pursue World Bank mega-projects
- Firms with $50–200M: focus ADB, AfDB, EBRD
- Firms with $5–50M: NDB, AIIB, regional NCB tenders
- SMEs: subcontract to Tier-1 firms or target IsDB/AFD niche sectors
4. Geographic Diversity Creates First-Mover Advantage
AfDB's presence in 54 countries (rivaling World Bank's 149 but with far fewer tenders) and AFD's 62-country reach suggest pockets of underbidding—fewer competitors pursuing tenders in smaller, less-developed countries. Early entry into Tanzania (AfDB), Senegal (AFD), or Georgia (EBRD) can establish relationships before global contractors mobilize.

Implications for Contractors
Tier-1 Firms ($500M+ revenue)
- Focus: World Bank mega-projects (infrastructure, private-sector reform, education systems)
- Strategy: Maintain active World Bank prequalification across 3–5 contract categories (services, works, goods); bid high-value opportunities ($50M+) where scale advantages matter
- Timeline: 24-month bid cycles average; pipeline lag 3–6 months (i.e., tenders posted today reflect programs approved 6 months ago)
Mid-Tier Firms ($50–200M)
- Focus: ADB, AfDB, EBRD (regional depth)
- Strategy: Establish country presence in 2–3 priority markets; pursue joint ventures with local firms to capture NCB volume (smaller deals, faster cycles)
- Timeline: 12–18 month bid cycles
SMEs ($5–50M)
- Focus: Subcontracting to Tier-1 firms; NDB/AIIB/IsDB niche sectors; local NCB tenders
- Strategy: Specialize in 1–2 subsectors (e.g., solar mini-grids, digital health, water supply) and build reputation with local implementing agencies
- Timeline: 6–12 month bid cycles
Emerging Opportunity: Central Asia via NDB
The New Development Bank's expansion to Uzbekistan (June 5, 2026) triggers a $10B+ procurement wave through 2027—3,000 small hydropower plants, 300 MW wind farms, transport corridors, water modernization. Contractors should:
- Pre-position in Uzbekistan H2 2026 (register with State Procurement Bureau, hire local legal counsel)
- Monitor NDB project announcements (expected Q4 2026) for engineering RFQs
- Form supply-chain partnerships with Turkish (Enerjisa, Kalyon), Chinese (Sinohydro, Power China), and Indian (L&T, Suzlon) firms already active in region
---
Looking Ahead: H2 2026 Pipeline
The MDB procurement landscape in H2 2026 will be shaped by:
- World Bank's $30B FY2026 commitments (ending June 30) rolling into new fiscal-year projects (July 1), creating a surge in project launches and accompanying RFQs for implementation support, monitoring, and capacity-building consulting.
- ADB's $20B Asia-wide focus on climate adaptation (Bangladesh cyclone resilience, Vietnam Mekong delta), digital infrastructure (Myanmar, Tajikistan fiber), and CPTPP trade integration (Vietnam, Indonesia, Philippines customs automation).
- NDB's Uzbekistan momentum accelerating through Q4 2026 (first energy projects, transport feasibility studies).
- AfDB's gender-focused lending (African Women in Trade Initiative) creating new opportunities in SME finance, agri-value-chain development, and digital services.
- EBRD's Egypt expansion post-IMF bailout (2024–2026), with new energy privatization tenders and PPP infrastructure concessions expected H2 2026.

Conclusion
The MDB procurement market is not monolithic. While the World Bank dominates by sheer volume, each multilateral development bank offers distinct opportunities in terms of contract size, geographic focus, sector specialization, and payment terms. Contractors should map their core competencies to the MDB that best fits their scale, geography, and sector expertise, rather than pursuing a generic "all MDBs" strategy.
Next steps: Review the World Bank, ADB, and AfDB tender pages on BidsFactory to compare current pipelines in your target region. Filter by country and sector to identify early-stage opportunities before larger competitors mobilize.
