The poll that made the California governor race look close this week came with a line most readers skipped. On August 24, GV Wire reported a text-message survey of 912 registered voters, taken August 14 to 18, with Democrat Xavier Becerra at 49.2% and Republican Steve Hilton at 41%. It was commissioned by Hilton's campaign. Eleven days earlier the Berkeley IGS Poll of 2,310 likely voters had Becerra 55 to 37; the July reading from the Public Policy Institute of California, per the Washington Examiner, was 61 to 36. No poll Hilton did not pay for has had the race inside 18 points since the field was set.
The people with money on the question read it the same way. On Kalshi, where a price in cents is a probability, the contract that pays $1 if Becerra is elected governor on November 3, 2026 was quoted at 8:51 a.m. Eastern on Thursday at 96.3 cents by buyers and 96.4 by sellers: about a 96% chance. Hilton's contract was 3.3 to 3.4. The strongest fact behind those numbers is not a poll. It is the certified count from the June 2 primary, where 9,262,468 Californians voted on this exact office and Democratic candidates took 62.38% of the ballots to 35.95% for Republicans.
What needs explaining is why the cheap side of this board is the busy one: 3.71 million Hilton contracts are open against 1.72 million on Becerra. That answer is below, and it is not what it looks like.

The Board
As of August 27, 2026, 8:51 a.m. Eastern (Kalshi, cents = probability; the bid/ask is what buyers will pay and what sellers want):
| Outcome | Yes price (bid/ask) | Reads as |
|---|---|---|
| Xavier Becerra (D) | 96.3¢ / 96.4¢ | about 96% |
| Steve Hilton (R) | 3.3¢ / 3.4¢ | about 3% |
Two rows is the whole board. The top-two primary put exactly two names on the November ballot, so the asks add to 99.8 cents and the bids to 99.6; the market leaves almost nothing for a third outcome. Each contract pays $1 if that person "is elected to the governorship of California pursuant to the election in 2026," and Kalshi can settle early on a consensus of media calls, so the November 3 vote decides it. The month's movement was small and ran one way. Becerra closed between 95.1 and 95.6 cents from July 31 through August 12 and has closed between 96.1 and 96.6 every day since August 19. Hilton closed at 5.5 cents on August 1 and 2, fell to 3.9 on August 18, the busiest day in the window at 156,344 contracts, and has closed between 3.5 and 4.3 since. From August 20 to 27, 183,323 Becerra contracts traded and buyers took 78% of them; 298,433 Hilton contracts traded and buyers took 76% of those. The biggest burst was 32,186 Becerra contracts bought in one second at 10:49 a.m. on August 20, at 96.3 to 97.0 cents, about $31,200. The biggest on Hilton's side was a bet against him: 26,814 contracts sold at 3.2 to 3.4 cents at 12:37 a.m. on August 26, risking about $25,950 to win about $860, which knocked his price from 3.8 to 3.2. In the 24 hours to 8:51 a.m., 18,870 Becerra contracts traded, 96% of them sellers, and his last print slipped from 96.5 to 96.1. Now the open-interest gap. Open interest counts contracts, not dollars, and a 3-cent contract is cheap to hold in bulk: the 3.71 million open Hilton contracts are about $126,000 on the "yes" side and about $3.58 million on the "no" side. The biggest pile of money betting on Becerra is sitting in Hilton's contract, as "no". Polymarket at 8:56 a.m. had Becerra at 95.2 to 95.3.
What the Models Think
We also put the question to our panel of forecasting programs, which we grade in public against real settlements, without showing them the price, only the sourced record below. Three of the panel's eight seats ran this board. Their middle answer put Becerra at 95%, a point under the 96-cent market. Two put him at 95% and 96%, for the reasons above: the 45-to-25 registration edge, the 18- and 20-point Democratic wins in 2022 and 2024, no Republican statewide winner since 2006, and a challenger whose own poll has him eight points down. One model: "candidates leading by 15+ in a state with a 20-point partisan lean lose essentially never; the residual ~5% covers tail risks." The third filed a 5 and then wrote, in its own reasoning, that the Becerra number should be high, not low; that is an answer keyed backwards, and we report it as filed rather than fix it. All three named the same thing that would change their minds: a nonpartisan poll with Hilton in single digits. The market has real money behind it. The panel has only the record. These are model estimates, not predictions of fact and not financial advice.
The Primary Did the Math: Sixty-Two to Thirty-Six on Nine Million Ballots
The old version of this page was about the 23 names Kalshi settled to "no" in June. That story now fits in a sentence: 68 candidates were on the June 2 ballot, and under California's top-two rule the first two advanced whatever their party. The certified Statement of Vote has Becerra first with 2,591,857 votes (28.0%), Hilton second with 2,277,318 (24.6%), Democrat Tom Steyer third with 2,110,707 (22.8%) and Republican Chad Bianco at 941,708 (10.2%); Hilton beat Steyer for the second slot by 166,611 votes. The Associated Press did not confirm Becerra's place until Friday, June 5, per the Sacramento Bee, and Gov. Gavin Newsom, who had stayed out of the primary, endorsed the following Tuesday: "I'm proud to support Xavier as our nominee for Governor and look forward to helping ensure a smooth transition. He will stand up to Donald Trump, defend our families, and keep California moving forward." Newsom's own next race is on Kalshi's 2028 Democratic board.
Becerra's 28% looks thin until you add the columns: Democrats on the ballot took 5,777,936 votes, Republicans 3,329,636, a 26-point gap on the same electorate voting for the same office. That gap is the state. The Secretary of State's April 3 registration report has 44.92% of 23.1 million voters registered Democratic, 25.03% Republican and 22.76% with no party preference; the Republican share is up from 23.92% in 2022, which is the trend Hilton is running on, and it is still a 20-point hole. Newsom beat Brian Dahle 59.18% to 40.82% in 2022; Kamala Harris beat Trump here 58.47% to 38.33% in 2024. Every other governor's race on the exchange is on our 2026 governor races board, and the backdrop, a Republican White House in a midterm year, runs through the 2026 midterm boards. In the August IGS poll, no-party-preference voters, the ones who decide California elections, went 58 to 30 for Becerra, and IGS co-director Eric Schickler wrote that "Hilton would need to make major inroads among traditionally Democratic leaning groups to make this a highly competitive race."
Hilton's Attack, Hilton's Poll and Becerra's Money
Hilton, a London-born former adviser to British Prime Minister David Cameron and former Fox News host, has Trump's endorsement, posted to Truth Social on April 6 per Fox News: "Steve Hilton has my COMPLETE & TOTAL ENDORSEMENT. He will be a GREAT Governor and, importantly, WILL NEVER LET YOU DOWN!!!" His central attack is Becerra's record running the Department of Health and Human Services from 2021 to 2025, which includes the office that places unaccompanied migrant children with sponsors. In Fresno on August 6, per ABC30, Hilton said: "Becerra not only failed to protect children in his care, he actively put them at risk. At risk of child sex trafficking, at risk of child labor exploitation, at risk of simply disappearing." Becerra's spokesman Jonathan Underland, in The Daily Signal on August 7: "Where Secretary Becerra rebuilt the child protection systems [President Donald] Trump gutted, Steve Hilton has proudly allied himself with the president who put those children in harm's way." The attack has run for a month. Hilton's price over that month went from 5.5 cents to 3.3.
Becerra has handed his critics a different opening: caution. CalMatters on August 20 described a candidate who will not name a housing target and said, "I would prefer not to run on inflated promises. I will run on my record." The same piece recalled his 2019 refusal, as attorney general, to release police-misconduct records under a new transparency law; courts ordered them released and assessed about $1 million in attorney fees. Hilton posted on X, per the Los Angeles Times, that "Xavier Becerra wants to be governor while dodging questions from the press and a debate with me." Becerra's answer on August 19: "We will have debates, and between now and Nov. 3, we will continue to go out there and meet with folks." No date or host has been set.
Then the money, which the market watches most closely. Per Dan Morain in Capitol Weekly on August 22, "Donors gave Becerra's campaign for governor $1.9 million in the first 15 days of August to Republican Steve Hilton's $690,000 in four- and five-figure sums," and 17 donors gave Becerra the $39,200 maximum against six for Hilton. Hilton's side of the ledger is small-dollar: the midyear filing showed he "significantly outraised Becerra in donations of less than $1,000," and his spokesman Hector Barajas says the campaign has more than 100,000 donors.

What Moves The Price From Here
- September 2026: the next independent polls. The August Berkeley IGS release came out August 13 and PPIC's last survey fielded through July 6; both are due again. All three forecasters named the same trigger, a nonpartisan poll with Hilton inside ten points. Another 18-to-25-point reading leaves the board where it is.
- The debate, when it gets a date. Becerra promised "debates" on August 19; Nexstar has proposed one and Hilton has demanded several. A televised general-election debate is the one scheduled event that can move a 3-cent contract in a night, and it is not yet on the calendar.
- November 3, 2026. Election Day. Kalshi can settle on a consensus of media calls that night; the January 2027 swearing-in is the formal close. Either way, this one is decided on November 3, 2026.
