Cost of Living: San Francisco vs Chicago (2026)

Chicago's tech-employer story is genuinely different from Austin or Dallas. Chicago doesn't host pure-play software companies at SF scale (no Stripe, no Databricks, no OpenAI equivalent). What it has instead is the world's largest derivatives, futures, and exchange infrastructure — and the fintech ecosystem built around that infrastructure.

The five major financial exchanges in Chicago:

• CME Group — Chicago Mercantile Exchange. World's largest derivatives marketplace by volume. Trades futures and options across interest rates, equity indices, foreign exchange, energy, agricultural products, metals, and more. ~3,500 employees.
• CBOE — Chicago Board Options Exchange. Largest US options exchange. ~700 employees.
• CBOT — Chicago Board of Trade. Owned by CME Group. Agricultural and Treasury futures.
• CHX — Chicago Stock Exchange (acquired by NYSE in 2018, now operating as NYSE Chicago).
• NYSE Arca — Maintains Chicago presence for ETF and equity trading.

The named SF→Chicago career pipeline lands here:

• Citadel — Multi-strategy hedge fund founded by Ken Griffin. Citadel HQ relocated from Chicago to Miami in 2022 but Chicago remains core to operations with thousands of staff. Citadel Securities (market-making arm) actively recruits from SF tech for quant and engineering roles.
• DRW Trading — Proprietary trading firm. Major Chicago employer for quant developers and infrastructure engineers.
• Discover Financial Services — Riverwoods, IL HQ. Major fintech employer for product, engineering, data science roles.
• Northern Trust — Chicago HQ. Wealth management technology + asset servicing platforms.
• Morningstar — Chicago HQ. Investment research and software platforms.
• Capital One Discover merger (2024-2025) — added Capital One Chicago presence to the existing Discover footprint, expanding fintech employment.

For SF tech workers specifically considering Chicago, the fit is narrower than 'just any tech job.' The career pipeline is fintech, exchange technology, quantitative trading infrastructure, and wealth management platforms. For pure-play AI, SaaS, consumer apps — Chicago has options but SF, Austin, and Seattle dominate. The SF→Chicago migration that does happen tends to land in this fintech/trading-tech corridor, where Chicago is structurally distinctive.

California's Proposition 13 (passed 1978, constitutional amendment) caps property assessment increases at 2%/yr regardless of market value. For long-term SF homeowners, this creates a math distortion specific to this pair that doesn't apply to most other comparisons.

Worked example: Consider an SF homeowner who bought in 2005 for $700,000. Current market value: ~$1.6M. Under Prop 13, the assessed value remains ~$1.05M (2% annual increases since 2005), so property tax is ~$7,800/yr at SF's 0.74% rate. The same household moving to Chicago and buying a $700K home pays ~$15,890/yr in property tax — over 2x what they pay in SF on a $1.6M-market-value home.

Now layer on income tax: at $200K wages, Chicago saves $5,100/yr in income tax vs SF. Net: SF homeowner moving to Chicago LOSES roughly $3,000/yr ($8,090 property tax increase minus $5,100 income tax savings). At higher incomes the math reverses — at $500K wages Chicago saves $29,250/yr, dwarfing the $8,090 property tax penalty.

The threshold: for long-term SF homeowners (10+ year Prop 13 basis), Chicago becomes financially favorable only at roughly $300K+ household income. Below that, the property tax inversion eats the income tax savings. For renters or new SF buyers (full Prop 13 basis), the threshold is much lower — Chicago favorable at $100K+ income.

For long-term SF homeowners specifically, this pair often favors staying — not because Chicago is bad, but because Prop 13 is THAT valuable. The same person at the same income but renting would face a clearly favorable Chicago math.
