Resolution criteria on PolyGram: The California primary is currently scheduled to take place on June 2, 2026. This market will resolve "Yes" if the listed candidate advances from the primary to contest the seat for California's 13th congressional district in the U.S. House of Representatives in the 2026 midterm elections. Otherwise, this market will resolve to "No". If no nominees are announced by November 3, 2026, 11:59 PM ET, this market will resolve to "Other". The resolution source for this market will be a consensus of official sources, including https://www.sos.ca.gov/. Any replacement of the nominees before election day will not change the resolution of the market.
PolyGram is an on-chain prediction market where you trade YES or NO outcome shares with real USDC on Polygon. For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution. Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.
Market outcomes
| Adam Gray | 93% YES | 8% NO |
| Kevin Lincoln II | 90% YES | 10% NO |
| Daniel Garibay Rodriguez | 4% YES | 96% NO |
| Vin Kruttiventi | 8% YES | 93% NO |
California's 13th congressional district will hold its primary election on 2 June 2026 as part of the broader midterm cycle. The market tests whether the designated candidate advances past this primary to face general election competition in November 2026. The 93% implied probability on Polymarket's order book reflects high confidence in primary advancement, though this assessment depends entirely on the candidate remaining viable through the settlement window and facing no unexpected disqualifications or withdrawals.
Primary advancement rates in California's congressional races historically exceed 95%, as the state's open primary system typically allows the top two finishers regardless of party affiliation to proceed to the general election. The 13th district, which covers parts of the Central Valley, has seen consistent primary participation and ballot access compliance in recent cycles. The 7% discount from near-certainty pricing likely accounts for tail risks including candidate withdrawal, death, or disqualification—scenarios that materialise in fewer than one in twenty races nationally.
Traders should monitor California's Secretary of State filings for any changes to candidate registration or ballot status between now and the June primary. The candidate's campaign finance disclosures and local media coverage will signal any material deterioration in viability. The critical deadline for candidate withdrawal or replacement varies by office; any announcement of serious health issues, legal complications, or campaign suspension would immediately pressure the market probability downward. The resolution source's reliance on official SOS records means only formally documented changes will trigger resolution adjustments.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
The mechanics for trading "CA-13 Primary Winners" are the same as any other PolyGram event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$2K in lifetime turnover and $8K of resting liquidity puts this market in the below the median by volume for elections contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.

The market has been open for under a month — fresh enough that information asymmetry remains a real factor.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
