Sakarya, by the numbers: 9.5 million m³ a day now | 20 million in 2027 | 45 million planned for 2028 | 785 billion m³ of Black Sea finds | $3.5 billion a year in imports saved, per the government
LEAD · GAME CHANGERS
Turkey’s Own Gas Is About to Double. The Prize Is a Smaller Import Bill.
Turkey’s first floating gas platform sailed for the Black Sea on Saturday to lift daily output from 9.5 to 20 million cubic meters by 2027.
BY MEHMET ISTANBULLU · ABOUT 6 MINUTES
On Saturday, Oct. 17, Osman Gazi left the port of Filyos on Turkey’s Black Sea coast for the Sakarya gas field, about 170 kilometers offshore. It is the country’s first floating production unit, a gas-processing plant on a hull that will work the field for the next 20 years. Energy Minister Alparslan Bayraktar said the aim is to light its flare, the sign that production has begun, “before the end of this year.” [1]
The vessel is 298.5 meters long and 56 meters wide, is equipped with 21 units and will house 140 personnel. [2] Bayraktar compared its height to a 40-story building. [5] President Recep Tayyip Erdoğan called it “the first factory of the Blue Homeland” and said that from 2027 one in every three households will use gas from the Black Sea. [2] About 7,000 people worked on the project, Türkiye Today reported. [8]
Sakarya has a short history. Erdoğan announced the Tuna-1 discovery on Aug. 21, 2020, at 320 billion cubic meters, later revised to 405 billion, and the official estimate for all Black Sea finds now stands at 785 billion. Gas reached shore in April 2023 and entered the grid in late August that year. [3] The field has produced 7.23 billion cubic meters so far. [1]
WHY IT MATTERS
Phase 1 draws on 12 wells at 9.5 million cubic meters a day, enough for about 4 million households. With Osman Gazi and 10 more wells, output is set to reach 20 million cubic meters a day in 2027 and supply 8 million households. A second floating unit, now under construction, is due to lift the field to 45 million cubic meters a day from 32 wells in 2028, about 17 million households, or 75% of homes with gas. [1] Reuters reported that the second platform is planned for the first quarter of 2028 and adds 25 million cubic meters a day. [4]
Set that against demand. Turkey consumed 59 billion cubic meters of gas last year and produced 3.1 billion of it, according to Reuters; the 20 million a day from Osman Gazi equals about 7.3 billion cubic meters a year. [4] By this newsletter’s arithmetic, 45 million a day comes to about 16 billion cubic meters a year, more than a quarter of last year’s consumption.
Then set it against the bill. Turkey spent $62.47 billion on energy imports in 2025, down 4.8% from $65.59 billion a year earlier. [6] In the first nine months of 2026 the bill was $53.4 billion, $6.6 billion more than in the same period of 2025, Akbank’s research team said. [7] Bayraktar told the broadcaster Kanal 7 that the added output is worth about $10 million a day, or $3.5 billion to $3.6 billion a year at today’s prices, from 2027. [5] The presidency’s Communications Directorate also puts the contribution at $3.5 billion a year. [2]
Bayraktar used the same interview to set out the household picture. He said no electricity or natural-gas price change is planned for October and November. Households pay about $220 per 1,000 cubic meters of gas, he said, against about $1,000 in Europe, and the state’s share of the cost is “well above 50%.” The annual consumption limit for subsidized household electricity, cut from 5,000 kilowatt-hours in 2025 to 4,000 in 2026, may be lowered again in 2027, he said. [5]
WHO BUILDS IT
For contractors, Sakarya is one of the largest work programs in the country. Rönesans Endüstri Tesisleri, part of the Rönesans group, holds the lump-sum turnkey contract to refurbish, extend the life of and convert the Phase 2A platform at Filyos over 2025 and 2026, for TP-OTC, the field’s state operating company. [9] Italy’s Saipem won the commissioning contract from GOE Petrol Sanayi on Sept. 8, about eight months of work, after an operational-readiness contract in April; the field lies in about 2,150 meters of water. [10] SLB, Subsea7 and Saipem won the Phase 2 subsea and pipeline work in May 2023. [11]
The second platform is being built in China. Wison New Energies began construction of the Phase III unit at its yard in Nantong on Feb. 6. The hull measures 282 by 54 meters and is designed for 30 years of service; float-out is planned for April 2027, with installation and commissioning by the end of that year. [12]
PROFILE: ALPARSLAN BAYRAKTAR
Bayraktar, 51, was born on July 9, 1975, in Kırıkhan, in Hatay province. He studied mechanical engineering at Istanbul Technical University, holds master’s degrees from Bilkent University and Tufts University’s Fletcher School and earned a doctorate at Middle East Technical University. He sat on the board of EPDK, the energy market regulator, from 2010 to 2016, served as deputy energy minister from 2018 and became minister on June 4, 2023. [13]
He speaks about Sakarya in output figures, household counts and dollars saved. This weekend he also said Turkey will receive some diesel under the U.S.-Russia supply deal and that exploration in Pakistan is running about six months behind schedule. [4] In this editor’s judgment, a former regulator who speaks in cubic meters and kilowatt-hours is inviting the market to measure Sakarya by what it delivers.
THE BEST MOVES
Model Turkey’s external accounts with Sakarya in them. By the minister’s figure, Osman Gazi alone is worth $3.5 billion to $3.6 billion a year in imports not bought from 2027. Build it into any view of the current account and the lira. [5]
Audit your electricity use. If your household or small business sits near the subsidized-consumption limit, measure it now; the minister has signaled a lower limit for 2027. [5]
Mark the second platform’s float-out in your calendar. April 2027 in Nantong is the date that decides whether the 2028 volumes arrive on time. [12]
WHAT TO WATCH
The bottom line: In this editor’s judgment, Sakarya changes Turkey’s balance sheet one well at a time. Each step from 9.5 to 45 million cubic meters a day is a dollar not spent abroad and a contract written at home.
IN BRIEF
BUSINESS
Turkish Builders Join Three of Six Bids for Dubai’s $9.2 Billion Metro Line
Six consortia submitted prequalification statements on Oct. 9 for the main contract on the Dubai Metro Gold Line, MEED reported. Turkish contractors sit in three: Doğuş with Alstom, China Railway Engineering Corporation and National Projects Construction; Limak and MAPA with China’s CRRC; and IC İçtaş with Egypt’s Hassan Allam and Siemens. Chinese state groups are in four of the six. [15] The fully underground line will run more than 42 kilometers with 18 stations, add 35% to the network and serve 1.5 million residents. Sheikh Mohammed bin Rashid Al Maktoum put the cost at about 34 billion dirhams ($9.2 billion). The winner designs and builds everything from tunnels to trains, supports operations for three years and must finish by September 2032. [15] Limak, MAPA and CRRC won the Blue Line in December 2024 for 20.5 billion dirhams ($5.6 billion); the Gold Line award is expected in 2027. [16]
The move: If you supply tunneling, signaling or station fit-out, approach the three teams with Turkish partners now, before their subcontractor lists are fixed.
TECH
Spyware Now Rides In on Ordinary Phone Ads, Citizen Lab Finds
Citizen Lab, at the University of Toronto, reported on Oct. 15 that Discover-Tech, an Israel-based company, let spyware makers use its advertising platform, Controlium, to push zero-click spyware to chosen targets through real-time ad auctions. [17][18] At least two spyware makers, Candiru and Bindecy, used it. At least 45 Windows computers at Al Jazeera were apparently infected with Candiru’s spyware in 2024 and 2025 after being shown ads laced with malicious code. Exposed bidding records show the ads ran across tens of thousands of apps and websites between March and June 2026, including on government and military networks. [19] The researchers found ads from the system in Duolingo, dating apps, period trackers, Yahoo Mail, Viber and Truecaller; Google and IAB Europe dropped the firm from their vendor lists. [17]
The move: Follow the lead researcher’s advice for anyone who may be a target: turn off ad tracking on your phone, or block ads altogether. [19]
LIFE
Frequent, Unplanned Naps Signal Higher Dementia Risk
Older adults who nap on most days, or fall asleep without meaning to, face a higher risk of dementia, according to a Johns Hopkins study published online Oct. 5 in The Journal of Gerontology: Medical Sciences. Researchers followed 995 Medicare beneficiaries aged 65 and older, free of dementia in 2013, for up to 10 years. Frequent napping was linked to a 48% higher risk, unintentional napping to 39% and naps of 30 minutes or less to 40%, after adjusting for nighttime sleep and health conditions. [20] “More frequent napping could be a marker of changes in the brain, rather than a cause,” said Adam Spira, the senior author. The study is observational and relies on self-reported naps, so it shows an association, not a cause. [20]
The move: If an older parent has started dozing off during the day without meaning to, mention it at their next checkup.

The Psychiatrist Who Switched On Neurons With Light Wins a Nobel
Karl Deisseroth shares this year’s medicine prize for optogenetics, a tool borrowed from a green alga that is now being tested to restore sight.

On Oct. 5 the Nobel Assembly at Karolinska Institutet awarded the 2026 Nobel Prize in Physiology or Medicine to Karl Deisseroth of Stanford, with Peter Hegemann and Georg Nagel, “for their discoveries concerning light-gated ion channels and optogenetics.” They share 12 million kronor ($1.22 million). [21][25] Hegemann wondered how Chlamydomonas, a single-celled alga, swims toward light; in the early 2000s he and Nagel found the protein behind it, channelrhodopsin. Deisseroth put its gene into rat nerve cells and, in 2005, fired them with blue light. Two years later he made the switch work in the brains of living mice. [21]
Born in 1971, he earned a doctorate in 1998 and a medical degree in 2000 at Stanford, where he is the D.H. Chen Professor of bioengineering and of psychiatry, and he is an investigator at the Howard Hughes Medical Institute. [21] He still sees patients. The call from Stockholm came just after he had gone to bed, and he has, in the interviewer’s words, “a house full of kids.” Psychiatry, he said, matters to him because “so much mystery now finally seems on the brink of elucidation.” [22] The method has already been tested in blind people with retinitis pigmentosa, he told WBUR, to give back some sensitivity to light. [23]
The move: In this editor’s judgment, the first optogenetic treatments will reach the eye long before the brain. If anyone in your family has an inherited retinal disease, ask their specialist which trials they could join.

A Ring That Reads Blood Pressure Without a Cuff Is Cleared
Happy Health, based in Austin, Texas, has FDA clearance for blood-pressure readings from its Happy Ring, a sleep-tracking ring worn on the index finger. It needs no calibration against a cuff; the company says that makes it the first such device. Readings combine light sensors with bioimpedance and physics-based models of how vessels expand and contract. It is available to buy directly or through a physician. [27]
The FDA letter, dated Sept. 3, covers spot-check readings at home or in a clinic for adults aged 22 to 50. [26] “This is blood pressure’s CGM moment,” said founder Dustin Freckleton, comparing it with continuous glucose monitors. The company raised $75 million in August. [27]
The move: Read the age range before you buy one for a parent: at 51 or older, the clearance does not apply.

Economists Expect Turkey’s Policy Rate to Fall to 36% on Thursday
The central bank’s Monetary Policy Committee meets on Thursday, Oct. 22. Fifteen of 17 economists in a BloombergHT survey expect a cut of 100 basis points, to 36%, and two expect 150. Their median sees 35% at the end of this year and 28% at the end of 2027. [28] Annual inflation fell to 29.73% in September, the first reading below 30% since November 2021; the bank held its rate at 37% on Sept. 10. Finance Minister Mehmet Şimşek said on Oct. 16 that legal changes for the capital markets will come by early 2027. [14]
Builders are watching. Construction contracted 1.9% in the second quarter after 14 quarters of growth, Herbiremlak reported, and Saint-Gobain plans a factory in Ankara in 2027. [29] Emlak Konut, the listed developer, sold 3,269 units and 25 plots in the first nine months for 62.33 billion lira ($1.26 billion), 56 of the units to foreign buyers. [25][30]
The move: Build the economists’ medians, 35% this year and 28% next, into your Turkish property and project forecasts, and run a second case with a smaller cut.
BUSINESS
Iraq Offers to Pay Turkish Builders in Oil for Its Trade Corridor
Iraq is working on an oil-for-financing agreement with Turkey to set up a fund for the Development Road, under which Turkish companies would build the corridor and be paid through crude exports, said Fadhil Abbas, director of projects at Iraq’s state railway company. The first phase will be backed by a World Bank loan, and the project is in detailed engineering and design. [31][32]
The $17 billion corridor would link the Grand Faw Port in Basra to the Turkish border by rail and road, and on to Europe. The railway is planned to carry 3.5 million tons in its first phase and 7.5 million in its second. [32] The World Bank-funded stage upgrades lines from Baghdad to Basra and Umm Qasr and north through Mosul toward the Fishkhabur border crossing. [31]
The move: Turkish rail and highway contractors should register with Iraq’s railway company now, and price oil-price risk into any bid paid in crude.

Order an iPhone Duo Today and It Arrives Late in January
Apple opened pre-orders for the iPhone Duo, its first foldable, at 5 a.m. Pacific time on Friday, Oct. 16. By 5:30 a.m., Apple’s U.S. online store showed delivery on Jan. 25 for both colors and all four storage sizes, from 256 gigabytes to 2 terabytes, MacRumors reported, according to Quartz. Prices start at $1,999. [33]
Apple said pre-order demand had been “nothing short of extraordinary” and that it would keep taking orders online. It did not say whether stores will have stock for walk-in buyers when the phone goes on sale on Oct. 23. [34]
The move: If you want one this year, check your nearest Apple Store’s pickup availability on the morning of Oct. 23; otherwise, use the wait to read the first independent hinge tests.

Where Republicans Stop Spending Tells You the Map
The Daily (The New York Times) · Thu., Oct. 15 · 34 min
Trailing in the polls, Republicans are making hard choices about where to spend, abandoning some races and pouring money into others, while President Trump campaigns almost daily in deep-red territory. Shane Goldmacher, Nate Cohn and Lisa Lerer walk through the map. [35] In this editor’s judgment, where a party pulls its money is a cleaner forecast than any poll. Anyone exposed to U.S. tariff policy should listen before Nov. 3.

Morbid: Debunking Modern Longevity Science
Saul Justin Newman · The MIT Press · Oct. 13, 2026 · 296 pages
Newman argues that the science of aging is full of misleading claims and bad records: the world’s oldest man is a fake, Blue Zones are debunked and five decades of research on human longevity are in doubt. He backs the jokes with mathematical evidence on how and why we age. [39] Read it before you pay for a longevity clinic, a supplement plan or a Blue Zones retreat.
