The OPEC Nations List, Answered First

OPEC has 11 member countries as of May 1, 2026: Algeria, Congo, Equatorial Guinea, Gabon, Iran, Iraq, Kuwait, Libya, Nigeria, Saudi Arabia, and Venezuela. The United Arab Emirates left the organization, which is why lists still circulating with 12 or 13 names are out of date. Angola exited earlier as well, so any list still naming Angola or the UAE as members is describing an earlier lineup, not the current one.

Together, OPEC’s members sit inside a global crude oil production base of 74.85 million barrels per day (bpd) in 2025, per the OPEC Annual Statistical Bulletin. Saudi Arabia is the group’s largest single producer and the country that most often drives group-wide quota decisions. For US readers, the practical stake is direct: OPEC countries supplied roughly 1 million bpd of the 2.2 million bpd of net crude the US imported in 2025, according to the EIA and Pew Research Center — a little under half of total US crude imports, with Canada alone supplying 57% of US crude imports that same year per World Population Review.

That’s the headline. The rest of this page breaks down each member’s output, what changed when the UAE left, how the group’s roughly 40% share of world crude supply feeds into the price you pay at the pump, and how to pull a fresher production number than the one printed here whenever OPEC issues its next bulletin.

OPEC Member Countries: The Full 2026 List

As of May 1, 2026, OPEC’s 11 members are:

• Algeria
• Congo
• Equatorial Guinea
• Gabon
• Iran
• Iraq
• Kuwait
• Libya
• Nigeria
• Saudi Arabia
• Venezuela

The United Arab Emirates announced its departure and formally exited effective May 1, 2026, confirmed in OPEC’s own press communications. Before that exit, the UAE accounted for about 4% of global crude oil production in 2025, per World Population Review — output that now sits outside OPEC’s coordinated quota system, at least on paper, even though the UAE remains a major exporter in its own right and continues to coordinate informally with OPEC+ partners such as Russia.

Two names that no longer belong on this list, despite showing up in older articles and AI summaries trained on stale data, are Angola and the United Arab Emirates. Angola left OPEC before the UAE did; the UAE’s exit is the more recent change and the one most likely to trip up anyone relying on a list written even a year earlier. If you need the list confirmed at the source rather than through a secondary summary, OPEC’s own press release from January 4, 2026 is the primary document, and it is the one to re-check whenever another member’s status is in question.

OPEC Oil Production: Global Share and Trends

Global crude oil production reached 74.85 million bpd in 2025, according to OPEC’s 61st Annual Statistical Bulletin. OPEC’s 11 current members produce a meaningful share of that total, though the UAE’s departure trims the bloc’s combined output relative to the 12-member figures still floating around older coverage. Saudi Arabia remains the de facto leader on production policy, and its quota signals are what markets watch most closely at each OPEC meeting.

Two supply-side factors are shaping 2026 pricing beyond routine quota-setting. First, the EIA’s Short-Term Energy Outlook assumes 0.6 million bpd of Middle East crude oil supply stays disrupted through December 2027 — a standing assumption in its forecasting model, not a one-time event, and one that keeps a floor under prices as long as it holds. Second, Brent crude has moved sharply over the past year: it closed at $91.52 per barrel on August 19, 2026 per Trading Economics, up 36.92% from its level in August 2025. The EIA’s own Q3 2026 forecast puts Brent nearer $85 per barrel for that quarter, so the spot price sitting above the quarterly forecast is itself a signal of tight near-term supply.

For US readers, that price move shows up directly at the pump. The EIA’s 2026 outlook puts wholesale gasoline at $2.91 per gallon against a retail price of $3.78 per gallon — a roughly 87-cent spread covering refining, distribution, marketing and taxes. Because OPEC quota decisions feed into Brent, and Brent feeds into wholesale gasoline within weeks, the group’s quarterly meetings are one of the more reliable leading indicators available for US fuel-cost planning.

What This Means for US Oil Imports and Pump Prices

The US imported about 2.2 million bpd of crude oil (net) in 2025, per Pew Research Center’s analysis of US production and consumption. Of that, OPEC member countries supplied roughly 1 million bpd, according to EIA data cited by the Alternative Fuels Data Center and World Population Review — meaning OPEC nations account for well under half of US crude imports even before counting the US’s own record domestic production.

Canada is the far larger supplier: it alone provided 57% of total US crude oil imports in 2025, per World Population Review — more than the entire OPEC bloc combined. That single fact reframes a lot of the “OPEC controls US gas prices” framing common in older coverage: OPEC’s leverage over US pump prices runs through the global Brent benchmark, not through direct US dependence on OPEC barrels, since Canada’s pipeline and rail links to US refineries dwarf what any OPEC member ships to US ports.

Where OPEC’s influence does bite for US buyers is through the Brent-WTI-gasoline chain: OPEC quota moves shift Brent, Brent and WTI move together, and US wholesale gasoline follows within a matter of weeks. Retail gasoline at $3.78/gallon against wholesale at $2.91/gallon in the EIA’s 2026 figures shows how much of the pump price is fixed distribution and tax cost rather than crude cost — which is also why a Brent move doesn’t translate one-for-one into a change at the pump. To track this yourself as OPEC’s next quota decision lands, the EIA’s daily spot price series at eia.gov/dnav/pet/pet_pri_spt_s1_d.htm is the fastest way to see Brent and WTI move before the retail-price effect shows up.

Sector Impact: Agriculture, Mining and Infrastructure

Agriculture: Fuel, Fertilizer and Farm Input Costs

US farm operations feel OPEC-driven oil price swings through diesel for tractors and irrigation pumps, propane for grain drying, and the natural-gas-linked cost of nitrogen fertilizer. USDA’s National Agricultural Statistics Service (NASS) tracks farm diesel and input prices seasonally, and with Brent up 36.92% year-over-year as of August 2026 per Trading Economics, operations budgeting fuel and fertilizer costs for the next planting cycle should check NASS’s current price survey rather than lean on a year-old per-gallon figure. The EIA’s $3.78/gallon retail gasoline figure for 2026 is a national average; diesel used in farm equipment tracks a related but separate EIA series worth checking directly for the current number.

Mining: Diesel, Processing Energy and Transport

Mining and mineral processing are energy-intensive at every stage — from diesel-powered haul trucks to grid or generator power for crushing and refining. Operations in oil-import-dependent regions are more exposed to Brent swings than those in the US, where domestic crude production offsets a large share of consumption. USGS mineral commodity summaries and the EIA’s production data together give a way to gauge how much of a given mine’s operating cost base moves with crude prices; for US-based mining, that exposure runs mostly through diesel and electricity rather than direct fuel imports.

Infrastructure: Construction and Public Works Costs

Public infrastructure projects — roads, grids, water systems — carry both direct fuel costs (construction equipment, hauling) and indirect costs through asphalt, a petroleum product whose price tracks crude. When Brent sits near $91.52/barrel as it did on August 19, 2026, compared with the EIA’s $85/barrel Q3 2026 forecast, project budgets built on the forecast number risk underestimating fuel and materials costs if spot prices stay elevated through the rest of the year.

Comparative Data Table: OPEC Members Ranked

The table below lists OPEC’s current 11 members alongside the two countries most often mistaken for current members. Individual member-by-member 2026 production quotas are not published in full detail in OPEC’s public bulletin at the country level needed for a complete ranking — OPEC’s Annual Statistical Bulletin is the primary source, and it publishes updated country tables annually, so check opec.org directly for the current breakdown by member.

For barrel-per-day figures by country, OPEC’s Annual Statistical Bulletin (opec.org/pr-detail/1784601-29-april-2026.html) is the authoritative annual source and the one to re-check for the current year’s country-level numbers, since a country-by-country production ranking for 2026 at the granularity many searches want is not detailed in the publicly available portion of the bulletin referenced here.

Fuel Cost Exposure Calculator

Use the figures above to estimate how a Brent price move flows through to your own fuel budget, based on the EIA’s 2026 wholesale-to-retail gasoline spread.

Assumptions: this scales your retail gasoline price by the same percentage change as the Brent inputs you enter, using the EIA’s 2026 retail gasoline figure ($3.78/gallon) and Trading Economics’ spot Brent figure ($91.52/barrel, Aug 19 2026) as defaults. It excludes diesel, refining-margin changes, taxes and regional price differences, and it is not a substitute for your own fuel supplier’s quote.

How to Track OPEC Decisions Going Forward

Because OPEC’s roster and quotas change — the UAE’s May 1, 2026 exit is the clearest recent example — a durable way to check the current state matters more than any single figure on this page. Three checks, repeated whenever a new OPEC meeting is announced:

• Membership: check opec.org’s press releases directly. The January 4, 2026 release documenting membership at 11 countries is the primary record; OPEC issues a new release whenever membership changes.
• Production and reserves: OPEC’s Annual Statistical Bulletin is republished each year with updated country-level figures — the 2025 edition (61st, referenced above) covers the 74.85 million bpd global total.
• Price and US market effect: the EIA’s Short-Term Energy Outlook (eia.gov/outlooks/steo) is updated monthly with fresh Brent, WTI, wholesale and retail gasoline forecasts, and its daily spot price series (eia.gov/dnav/pet/pet_pri_spt_s1_d.htm) updates each trading day.

For US-based agriculture, mining and infrastructure planning, that three-step check — membership, production, price — replaces the need to memorize any single year’s numbers. The EIA’s assumption of 0.6 million bpd of ongoing Middle East supply disruption through December 2027 is itself a variable worth rechecking each quarter, since a resolution or escalation would move Brent independent of any OPEC quota decision.

FAQs on the OPEC Nations List

What is the current OPEC nations list?

As of May 1, 2026, OPEC has 11 members: Algeria, Congo, Equatorial Guinea, Gabon, Iran, Iraq, Kuwait, Libya, Nigeria, Saudi Arabia, and Venezuela. The United Arab Emirates exited effective that date, and Angola exited previously.

How many countries are OPEC members?

11 countries, following the UAE’s exit on May 1, 2026. Membership has changed multiple times historically, so it’s worth confirming the current count against OPEC’s own press releases at opec.org rather than a list that doesn’t state its as-of date.

Is the UAE still an OPEC member?

No. The UAE exited OPEC effective May 1, 2026. It accounted for about 4% of global crude oil production in 2025 before its departure, per World Population Review, and continues to produce and export oil outside OPEC’s formal quota system.

How much oil do OPEC nations supply to the United States?

About 1 million bpd in 2025, versus total US net crude imports of 2.2 million bpd, per EIA data referenced by the Alternative Fuels Data Center, World Population Review and Pew Research Center. Canada alone supplied 57% of US crude imports that year — more than the entire OPEC bloc combined.

How does OPEC affect US gasoline prices?

Mainly through the global Brent benchmark rather than direct US import dependence. Brent traded at $91.52/barrel on August 19, 2026 (Trading Economics), up 36.92% year-over-year, while EIA’s 2026 figures put wholesale gasoline at $2.91/gallon and retail at $3.78/gallon — the gap covering refining, distribution and tax.

Where can I find OPEC production figures by country?

OPEC’s Annual Statistical Bulletin, republished each year at opec.org, is the primary source for country-level production and reserves data. Detailed 2026 country-by-country quotas were not available in the publicly accessible portion of the bulletin used for this article — check the current edition directly for the latest breakdown.

Conclusion: Key Takeaways

• OPEC’s current roster is 11 countries as of May 1, 2026 — the UAE’s exit is the change most likely to make an older list wrong.
• Global crude production ran at 74.85 million bpd in 2025 per OPEC’s own bulletin; Saudi Arabia remains the largest single OPEC producer.
• OPEC supplies under half of US crude imports — about 1 million bpd of 2.2 million bpd net imports in 2025 — with Canada’s 57% share dwarfing the entire OPEC bloc.
• Brent at $91.52/barrel (Aug 19, 2026) sat above the EIA’s $85/barrel Q3 2026 forecast, a gap worth watching for anyone budgeting fuel, fertilizer or construction costs.
• Check opec.org and eia.gov directly for the current membership list, production bulletin and price forecast rather than relying on any static snapshot, including this one.

The OPEC nations list is not fixed — it has changed twice in recent years with Angola’s and the UAE’s exits, and it will change again. The durable habit worth keeping is checking OPEC’s own press releases for membership, its Annual Statistical Bulletin for production, and the EIA’s Short-Term Energy Outlook for price, each time a new quota decision or supply disruption makes headlines.
