California's 52 House seats don't usually decide control of Congress. But in 2026 a half-dozen of them probably will. Prediction markets are already pricing the most competitive races, and traders in Los Angeles, the Central Valley, and Orange County can take real-money positions on every one of them. Here's the California congressional map through the lens of Kalshi and Polymarket, plus how to actually trade it from California.

Which California House races are on prediction markets?

Six California districts have live contracts in 2026: CA-22 (Valadao), CA-27 (Garcia), CA-41 (Calvert), CA-45 (Steel), CA-47 (Min vs. Baugh rematch), and the open CA-11 (Pelosi seat). A handful of safer R and D seats get listed as House-control liquidity grows, but the six above are where actual order-book depth lives today.**

The reason these six matter: every Cook Political Report toss-up or lean race in California flows into the national House-control contract. Trading them individually lets you take a sharper view than the aggregate market: useful when you live here, watch the local press, and have an edge the East Coast desk doesn't.

Is it legal to trade California political contracts from California?

Yes. These contracts trade on CFTC-regulated exchanges; the recent court fights over state gambling law have centered on sports contracts. For the full regulatory picture see our California legality guide.

California has no separate prediction-market license regime; the relevant authority is federal. As long as the contracts are listed on a CFTC-regulated Designated Contract Market (Kalshi) or its acquired equivalent (Polymarket's US product), California residents can hold positions (minimum age 18; we recommend 21+).

CA-22: Valadao (R) vs. Democratic challenger

The Central Valley toss-up. David Valadao keeps surviving in a D+5 district; markets price him near 50/50 every cycle. The 2026 contract is trading in a 45-55¢ band on Kalshi, with volume picking up as the Democratic primary narrows.

What moves the price: any Central Valley water-policy headline, ag-labor news, and the generic ballot. Valadao's incumbency advantage is real but thin, historically worth about 3 points in this district. If the national environment tilts even slightly D, this contract should price below 50¢.

CA-27: Mike Garcia (R) in the Santa Clarita corridor

Garcia held a Biden +12 district through 2024. Markets are skeptical he can do it again in a midterm with no Trump on the ballot. Kalshi has him trading around 40-45¢ as of June 2026.

The structural read: midterm electorates in LA County exurbs lean more Democratic than presidential years. Garcia's personal brand is the variable. Track Antelope Valley early vote and CA-27 fundraising disclosures. They tend to lead the contract by two to three weeks.

CA-41: Ken Calvert (R) in Riverside County

Calvert vs. Rollins, round three. The 2024 rematch was decided by under 5 points; 2026 looks even tighter on the board. Trading in the 48-52¢ range, with the line moving meaningfully on each Inland Empire jobs report.

Edge case worth watching: a heavy Democratic governor's race down-ballot effect. CA-41 turnout correlates closely with Riverside County turnout in the CA Governor 2026 contract, so the two markets move together.

CA-45: Michelle Steel (R) vs. Derek Tran (D), Orange County rematch

The closest 2024 House race in California (Tran flipped it by ~600 votes). 2026 priced as a true coin flip. 49-51¢ on both sides depending on the week. This is the most active race-by-race contract in the state.

Watch the Vietnamese-American voter share in Westminster and Garden Grove. The 2024 swing came almost entirely from that bloc; if it holds for Tran, the contract should drift above 55¢. If it reverts, Steel is favored.

CA-47: Open seat after Katie Porter, Min vs. Baugh rematch

Dave Min held the seat by 2.5 points in 2024 against Scott Baugh. The 2026 rematch is priced 52-58¢ Democratic on Kalshi, reflecting Min's small incumbency boost.

Coastal Orange County keeps drifting Democratic in presidential years and snapping back in midterms: the central question for this contract. Volume is thinner than CA-45 but the price discovery is sharper because both candidates are known quantities.

CA-11: Pelosi's open San Francisco seat

Speaker Pelosi's retirement opened CA-11. The contract is on which Democrat wins the jungle primary, not which party holds the seat. That's locked. Top-of-book trades the Scott Wiener vs. Christine Pelosi matchup.

Liquidity is light because the general-election outcome is not in doubt. This is a market for political junkies and people who follow San Francisco politics closely; it's not a high-volume contract.

How California congressional races interact with the national House contract

Six competitive California seats represent roughly 1.3% of the House but a disproportionate share of the toss-ups. If Democrats sweep all six, the path to a House majority gets meaningfully easier on the national contract. That correlation is tradable.

Practical approach: build a basket of all six California race contracts on Kalshi, then hedge with the national House-control contract on either Kalshi or Polymarket. The basket's expected value moves with California turnout; the hedge isolates the California-specific edge from the national environment.

Six California seats. One in eight tossup contracts in the country. The most underpriced state-level political market on Kalshi.

Frequently asked questions

Which California House races are on prediction markets in 2026?

Six: CA-22 (David Valadao), CA-27 (Mike Garcia), CA-41 (Ken Calvert), CA-45 (Michelle Steel vs. Derek Tran rematch), CA-47 (Dave Min vs. Scott Baugh rematch), and CA-11 (the open seat after Speaker Pelosi's retirement). Kalshi lists all six as individual race contracts.

Is it legal for California residents to trade California political contracts?

Available — dispute pending (as of October 13, 2026). Kalshi and Polymarket accept California residents (minimum age 18; we recommend 21+) and list these contracts on CFTC-regulated exchanges. The recent federal court fights have centered on sports contracts, and California has not brought its own case against the platforms.

Which California race is the closest?

CA-45 (Steel vs. Tran) is currently trading at roughly 49-51¢ on Kalshi: the tightest race-by-race contract in the state. Tran flipped the seat by about 600 votes in 2024 and 2026 looks similarly close.

Where can I trade these contracts?

Kalshi has the deepest race-by-race liquidity and lists all six California seats. Polymarket has cleaner pricing on the national House-control contract; its US race-by-race coverage is expanding. OG by Crypto.com offers Trade $25 Get $25 in Rewards! with code CAPREDICTS for traders opening their first account.

How do California races affect the national House-control contract?

Six competitive California seats represent about 1.3% of the House but a disproportionate share of national toss-ups. A Democratic sweep of all six measurably shifts the national House-control contract on Kalshi and Polymarket.

Does the California governor's race affect the congressional contracts?

Yes, turnout correlation is strong, especially in Riverside County (CA-41) and Orange County (CA-45, CA-47). The CA Governor 2026 contract and the down-ballot House contracts tend to move together on big turnout signals.

Are there position limits on California congressional contracts?

Yes, CFTC-imposed limits apply, typically capping individual exposure on political contracts. Limits are most often relevant on the most actively traded seats (currently CA-45). Casual retail trades rarely approach them.

What is the maximum position size for California congressional contracts?

Kalshi imposes specific position limits on political contracts, often capped at $7 million for eligible contract participants or lower for retail traders. Polymarket generally has no hard caps on position sizes, but liquidity limits how much you can trade without significant slippage. California residents should check the individual contract specifications for the latest limit updates.

Why are some California House races missing from prediction markets?

Platforms only list races with significant public interest and available polling data. Highly competitive 'toss-up' districts like CA-27 or CA-45 are frequently listed due to high trading volume. Non-competitive districts with safe incumbents rarely appear because they lack the two-sided liquidity required for a functional prediction market.
