Riyadh ranks first. San Francisco ranks sixth. The gap in raw total compensation runs $135,000 in favour of San Francisco: a $280,000 median base against $145,000. The gap in PPP-adjusted take-home runs the other way. A senior AI engineer in Riyadh retains every dollar of base salary and spends it in a city costing 53% less than New York. The same engineer in San Francisco keeps $108,000 from a $200,000 gross income and spends it in the most expensive tech hub in the world. That arithmetic, scaled across 20 cities using five equally weighted dimensions, is the central finding of ENTRA's August 2026 city compensation index. Where you earn matters. What you keep, and how far it goes, matters more.
Scoring Methodology
Each city is scored across five equally weighted dimensions at 20 points each, for a maximum composite of 100.
Median Base Salary (20 pts) measures senior ML engineer and AI software engineer median base in USD, normalized linearly across the 20-city universe. San Francisco ($280K) anchors the maximum; Bangalore ($70K) anchors the minimum.

Data window: Q2 2026 (April 1 to June 30, 2026) for salary and CoL data; trailing 12 months (Q2 2025 to Q2 2026) for growth trajectory; tax regimes as in force June 30, 2026.
The Top Five Cities
Riyadh, Saudi Arabia (76, A) leads on the two dimensions that matter most for PPP outcomes: a zero income tax rate (20/20 on Dim 3) and the fastest salary growth of any city in the index (+22% YoY, 20/20 on Dim 4). HUMAIN's $100B AI investment commitment is the demand signal behind that growth, drawing global AI talent at USD-denominated salaries into a city with a Numbeo CoL index of 50. Every dollar earned is a dollar kept, spent in a market that is half the cost of New York.
Abu Dhabi, UAE (75, A) holds second place through the same structural tax advantage combined with a more mature private-sector AI employer base: G42, Microsoft UAE, and the Technology Innovation Institute collectively sustain a $155,000 median base alongside the country's best-in-class AI policy infrastructure. The one-point gap to Riyadh reflects a marginally higher CoL index and slightly slower growth trajectory.
Dubai, UAE (74, A) rounds out the Gulf three with the highest median base of the Gulf cities ($165,000), driven by a broader private employer pool including Microsoft UAE, Amazon AWS Middle East, and the DIFC FinTech cluster. Zero income tax applies to the higher base, amplifying the absolute take-home advantage versus the other two Gulf cities.
Seattle / Bellevue, WA (73, A) is the highest-ranking US city and the top-ranked non-Gulf city globally. Washington State imposes zero income tax on earned income. Amazon and Microsoft engineering operations pay identical equity packages to their San Francisco counterparts. The result: same employers, same TC structures, $29,000 more in annual take-home on a $265,000 base.
Austin, TX (69, BBB) ranks fifth on the same 0% state income tax logic as Seattle, amplified by a CoL index of 68 versus Seattle's 82. Tesla AI, Meta's Austin campus, and Dell's AI infrastructure division sustain a $225,000 median base with equity grant structures inherited from their parent companies' US-standard packages. On raw PPP ratio, Austin edges Seattle, but a lower base salary keeps the composite below the A tier.
Why Gulf Cities Dominate
The Gulf's structural advantage is not salary level. It is the absence of income tax applied to salaries high enough to matter. At Riyadh's $145,000 median base, a zero tax rate produces $145,000 in take-home. The same salary in Berlin, at approximately 42% combined effective rate, yields $84,100. Spent in Riyadh at a CoL index of 50 versus Berlin's 66, the real consumption gap widens further. This dynamic compounds with every percentage point of salary growth. The +22%, +20%, and +18% YoY growth rates for Riyadh, Abu Dhabi, and Dubai mean the base salaries on which zero tax operates are increasing faster than in any other market in this index. The structural advantage is not static: it is accelerating.
Seattle Beats San Francisco on Take-Home
Both cities draw from the same employer pool. Amazon's engineering organisation spans Bellevue headquarters and San Francisco office locations. Microsoft Research operates in Redmond and Mountain View. The equity grant benchmarks are identical: both markets target p75-p90 of the Levels.fyi senior IC range. The only variable is the state income tax. Washington imposes none. California imposes 13.3% at the top marginal rate, which on a $280,000 base contributes approximately $30,000-$37,000 in additional annual tax versus the equivalent Seattle earner. At San Francisco's CoL index of 107 versus Seattle's 82, the Seattle engineer both keeps more and spends less. This is not a close call on the PPP dimension. Seattle scores 14/20; San Francisco scores 9/20.
The European Cluster
Zurich (49, BB) leads Europe by a narrow one-point margin over London (48, BB). Google Zurich, IBM Research, and the ETH AI Center sustain a $190,000 median base for senior AI engineers, per Levels.fyi Q2 2026 city-filtered data. Zurich canton's approximately 26% combined income tax rate is the lowest of any major European tech hub. The primary gaps to the A tier are low equity premium (0.35 ratio versus 0.78 in San Francisco), a high CoL index that dilutes the tax advantage, and slow salary growth (+7% YoY).
London (48, BB) punches below its employer cluster. Google DeepMind, Amazon Science Cambridge, Meta AI Research, and Wayve collectively constitute the strongest AI research presence outside the US. The structural constraint is the UK income tax system: the personal allowance taper between GBP 100,000 and GBP 125,140 creates an effective 60% marginal rate that substantially compresses senior AI engineer take-home. London's CoL index of 92 compounds the pressure.
Paris (37, B) shows the first signs of Mistral AI's effect on the local salary market at +7% YoY growth, the highest in the EU-4 cluster. But a combined effective rate of approximately 44% including employee social charges leaves the city materially below the European competition on tax-adjusted take-home. Berlin (36, B) scores lowest among European cities on growth trajectory (+5%), reflecting Germany's broader 2025-26 economic headwinds and the capital's concentration in early-stage startups rather than frontier labs. Stockholm (35, B) has the second-highest effective income tax rate in the index at approximately 50%, producing a $100,000 take-home on $200,000 gross: a structural ceiling that no employer cluster can overcome.
Emerging Markets: Bangalore and Singapore
Bangalore (52, BB) is the PPP story of this index. A CoL index of 28 (Numbeo, NYC=100) means take-home income carries approximately 3.0x the real consumption power it would in San Francisco. Google India, Microsoft IDC, Amazon India, and Meta India pay RSU grants denominated in USD at US employer benchmarks, while base salaries in local market terms run $60,000-$90,000. The +15% YoY growth rate, third-fastest in the index, signals a market closing the gap with Southeast Asian peers at pace.
Singapore (62, BBB) ranks seventh globally on the strength of a 20% effective income tax rate, a Numbeo CoL index of 83, and the deepest enterprise AI employer cluster in Southeast Asia. OpenAI's regional HQ, Anthropic APAC, Google DeepMind Singapore, and Meta AI Research all operate local engineering operations. The Tech.Pass provides a direct residency pathway for credentialed AI professionals without employer-of-record requirements.
What the EU Directive Changes
The EU Pay Transparency Directive requires member state enforcement from 2027, with penalty regimes operational from Q1 2027 in the most compliance-forward jurisdictions. The compensation transparency effect is already visible in this index's growth trajectory data: Paris (+7%), Amsterdam (+6%), and Berlin (+5%) are all below Singapore (+13%) and Bangalore (+15%), in part because EU AI employer growth is constrained by talent supply and slower macro conditions. The directive does not address the structural tax disadvantage that places every EU city in the B or BB tiers relative to Gulf and zero-state-tax US cities. What it changes is information asymmetry: from Q1 2027, senior AI engineers considering roles in Germany, France, or the Netherlands will have access to legally mandated salary band disclosures with cross-jurisdictional consistency requirements. The next refresh of this index, publishing August 2027, will measure whether greater compensation transparency in European cities produces a measurable increase in effective offer levels relative to posted band midpoints.

Data window: Q2 2026 (April 1 to June 30, 2026) for salary, CoL, and posting data; trailing 12 months (Q2 2025 to Q2 2026) for growth trajectory; tax regimes as in force June 30, 2026 Sample size: 20 cities scored; Levels.fyi Q2 2026 (n=6,200+ AI-title offers, city geo-tagged); ENTRA Salary Survey Q2 2026 (n=2,140 verified respondents); ENTRA Job Signal Index Q2 2026 (47,000+ AI postings); Numbeo Q2 2026 (20 primary cluster cities); Mercer Cost of Living 2026 (20 city cross-validation)
Limitations:
- Median base salary figures reflect each city's primary AI cluster employer tier (frontier labs, hyperscalers, major regional AI employers). Professionals at smaller employers or outside the primary cluster may see materially different compensation, especially in Bangalore (where FAANG India pay exceeds domestic market norms materially), Riyadh (where HUMAIN and government-adjacent roles dominate senior AI hiring), and Berlin (where early-stage startup compensation is substantially below the hyperscaler tier).
- Tax-Adjusted Net Comp is computed at a standardised $200,000 USD gross equivalised salary for cross-city comparability; it does not fully capture the interaction of actual city median salaries with each jurisdiction's progressive rate schedule.
