Alaska picks a U.S. senator through a two-step system this year, and the first step looks like a runaway. On Tuesday, August 18, 2026, Alaska runs its nonpartisan top-four primary, and Kalshi has former U.S. Representative Mary Peltola near 93¢ to finish first in that field. Read that number too fast and you would think the race is over. It is not close to over. The 93¢ is measuring the wrong thing, there are two men named Dan Sullivan on the same ballot, and the market that actually prices the Senate seat calls November a coin flip. This piece is about the gap between the loud number and the real one.

The Quick Answer
Kalshi has Mary Peltola near 93¢ to finish first in Alaska's August 18 top-four Senate primary, but finishing first barely matters in a system where the top four all advance, and the market pricing the November general has the seat at a near coin flip: Peltola around 56¢, Republican incumbent Dan S. Sullivan around 47¢. The wildcard is a second candidate, Daniel J. Sullivan Jr., whose name alone has him trading around 41¢ to sneak into the top four. Which number to trust, why the primary favorite is not the seat favorite, and how ranked-choice voting reshuffles all of it are below.
- First-Place Primary Favorite: Mary Peltola (D) ~93¢ to lead the August 18 field
- The Incumbent's Split: Dan S. Sullivan ~10¢ to finish first, but ~94¢ to advance to November
- The Ballot Twist: a second name, Daniel J. Sullivan Jr., ~41¢ to advance with the heaviest trading volume in the field
- The Seat Itself: priced as a toss-up for November, Peltola ~56¢ / Sullivan ~47¢
- The Read: the primary is a seeding round, and the real bet is a ranked-choice general

These are live market prices, not predictions of fact and not financial or voting advice. Kalshi event contracts trade on a CFTC-regulated exchange; you must be 18 or older and in an eligible state to participate, and this article does not advocate for or against any candidate or party.
The line to sit with in that table is the split between "finishes first" and "advances." They are two different bets, and once you separate them, Peltola's 93¢ stops looking like dominance and starts looking like arithmetic.
Why Peltola Is 93¢ To Finish First (And Why That Number Lies)
Here is the mechanism. Alaska scrapped closed party primaries in 2020, so every candidate for this seat, Republican, Democrat, Green, Libertarian, Alaskan Independence, appears on one August ballot, and the top four advance to November. The dynamic the market appears to be pricing is a familiar one: in a red-leaning state the Republican-leaning vote tends to scatter across several right-of-center names on a single ballot, while Peltola consolidates the left as the race's most prominent Democrat. Split one side, consolidate the other, and the consolidated candidate leads the raw count. That is why Kalshi has her near 93¢ to finish first, and it is also why the incumbent, Sen. Dan S. Sullivan, sits near just 10¢ to finish first while trading near 94¢ to advance.
I want to be blunt about what that 93¢ is and is not. The number is a near-certainty that Peltola tops a fragmented first round. What it is not is a statement about who wins the seat, because in a top-four primary finishing first and finishing fourth buy the exact same thing: a slot in November. The forward promise I made up top, that the loud number measures the wrong thing, is this line right here.
A top-four primary does not crown a senator. It seeds a bracket, and Peltola's 93¢ is a great seed, not a Senate seat.
So the honest way to read the primary board is to ignore the trophy and count the slots. Peltola near 93¢ to lead and Sullivan near 94¢ to advance means both frontrunners are all but assured of November. The suspense is entirely about the other two slots, and that is where the strangest story on the ballot lives.
The Two Dan Sullivans On One Ballot
There are two candidates named Dan Sullivan in this race, and that is not a typo. The incumbent is Republican Sen. Daniel S. Sullivan, in office since 2015. The second is Daniel J. Sullivan Jr. of Petersburg, a retired teacher and former U.S. Forest Service worker who filed for the same seat. I verified both against the state's certified field before writing a word about the second man, because a candidate name on a trading screen is not proof of a candidate on a ballot, and this is exactly the kind of detail worth double-checking.
The Alaska Division of Elections actually tried to keep the second Sullivan off, arguing he had not filed in good faith, but a superior-court judge ruled he must stay, and the Alaska Supreme Court upheld that in late June 2026. On the August ballot he is listed as "Daniel J. Sullivan Jr.," and even though he too filed as a Republican, no party label is printed next to his name, while the incumbent is marked as the incumbent. That is the whole confusion machine in one line: same last name, same party, no label to tell them apart. The saga is serious enough that, as NBC News and others have reported, the FBI, the Alaska attorney general and the U.S. attorney's office in Alaska have all looked into whether anyone conspired to plant a same-named challenger to confuse voters. No one is owed a conclusion here, and this article alleges nothing; the investigation is a fact, not a verdict.
The busiest contract on the entire board belongs to a first-time candidate with no party printed by his name. That is not a campaign the market is pricing. It is the odds that voters check the wrong Sullivan.
The market has an opinion about the confusion, and it is a loud one. Daniel J. Sullivan Jr. trades near 41¢ to advance to the top four, and his contract has drawn the heaviest volume of any name in the advance field, more than 23,000 contracts changing hands. Consider what that means: a first-time candidate with no party printed by his name and no statewide profile is priced as a live threat for a November slot, purely because a chunk of voters may check the wrong Sullivan. That is the whole reason his contract is the busiest on the board, and it is the cleanest example I can point to of a ballot quirk pricing higher than an actual campaign.
The Real Fight Is In November
Now the callback. Remember that Peltola's 93¢ is measuring the primary, not the seat. The three markets on this race ask three different questions, and lining them up side by side is the fastest way to see why one number can be a runaway and another a coin flip.
| Candidate | Finish first (Aug 18) | Advance to top four | Win in November |
|---|---|---|---|
| Mary Peltola (D) | ~93¢ | ~99¢ | ~56¢ |
| Dan S. Sullivan (R, Incumbent) | ~10¢ | ~94¢ | ~47¢ |
| Daniel J. Sullivan Jr. | n/a | ~41¢ | not yet a priced contender |
The row that reframes the whole race is the incumbent's. Sullivan is priced as near-certain to advance at 94¢, a near-zero to finish first at 10¢, and a near coin flip to actually win at 47¢. All three are true at once, because each answers a separate question, and only the last one hires a senator. The market that prices the seat is the November general, where the picture flips from runaway to razor's edge: Peltola around 56¢, Sullivan around 47¢. The two frontrunners who cruise through August are, nine cents apart, effectively even for the job itself.
Ranked-choice voting is why. In November, Alaska voters rank the four survivors, and if no one clears 50% on first choices, the last-place candidate is eliminated and their voters' second choices are redistributed until someone crosses the line. That single rule is what makes this a toss-up rather than a red-state lean: whoever leads the first-choice count is not guaranteed the seat, because a defeated candidate's second choices can break the other way and swing the final tally. Peltola's own 2022 win came under this same ranked-choice system, where second choices, not first-round leads, settled the result. Whether the November field includes two Sullivans, and how those second choices sort, is a live variable the market is clearly still chewing on.
So the causal chain runs the whole length of this race: a fragmented primary hands Peltola a gaudy first-place number, the top-four rule sends both frontrunners plus two wildcards to November anyway, and ranked-choice voting then relitigates everything from scratch. The 93¢ and the 56¢ are not in conflict. They are two different questions, and only the second one hires a senator.
How To Read These Prices Without Fooling Yourself: A Worked Example
This is an intermediate read, so I will assume you already know a Kalshi price in cents is just an implied probability: a contract at 41¢ means the market thinks that outcome is roughly 41% likely, and a fair-value winner settles at 100¢. If you want that foundation in full, our Kalshi explainer covers it. The specific trap this Alaska board sets is comparing numbers that answer different questions.
Work a concrete example. You see "Peltola 93¢" and "Peltola 56¢" on the same page and assume one of them must be wrong. Neither is. The 93¢ is the probability she finishes first in a split primary; the 56¢ is the probability she wins a ranked-choice general months later against a consolidated opponent. Reading them side by side and expecting them to match is the mistake. Sullivan is the same trap in reverse: near 10¢ to finish first looks like a candidate in trouble, right up until you read it next to 94¢ to advance and 47¢ to win the seat. Each price is honest about its own question. Your only job is to make sure you are reading the answer to the question you actually care about.
That habit, comparing a number to the specific thing it prices instead of the story around it, is exactly what our odds tools are built to enforce on the sports side: find the gap between a price and fair value, and act on the gap rather than the narrative. The Alaska race is not carried on OddsShopper, but if you want to watch that same discipline applied to games this week, our free expert picks are the place to start.
In Summary
Alaska's two-step system is doing exactly what it was built to do, and it is fooling anyone who reads only the top line. The 93¢ on Peltola is real and almost meaningless, a measure of a fragmented first round rather than a Senate seat. The seat itself is a coin flip priced near 56¢ to 47¢, a same-named challenger is drawing the heaviest volume on the board off nothing but ballot confusion, and ranked-choice voting will reshuffle the whole thing in November. When the votes are counted on August 18, the primary contracts settle and we will see which four names actually advance, but the number that decides who represents Alaska will not print until fall.

Frequently Asked Questions
What are the odds in the Alaska Senate race for 2026? On Kalshi's live markets as of August 16, 2026, Mary Peltola trades near 93¢ to finish first in the August 18 top-four primary, while incumbent Sen. Dan S. Sullivan sits near 10¢ to finish first but around 94¢ to advance. In the market pricing the November general, the seat is a near coin flip, Peltola around 56¢ and Sullivan around 47¢.
Why are there two Dan Sullivans on the Alaska ballot? The incumbent is Republican Sen. Daniel S. Sullivan. A second candidate, Daniel J. Sullivan Jr. of Petersburg, a retired teacher and former U.S. Forest Service worker, also qualified for the primary. The Alaska Division of Elections tried to remove him, but the Alaska Supreme Court ruled in late June 2026 that he must appear, listed as "Daniel J. Sullivan Jr." with no party shown next to his name.
How does Alaska's top-four Senate primary work? Alaska votes on Tuesday, August 18, 2026. Every candidate appears on one nonpartisan ballot regardless of party, and the top four advance to a ranked-choice general election on November 3, 2026. Finishing first is not the goal and does not decide the seat; advancing to November does.
Who is favored to win the Alaska Senate seat in November? The market pricing the November general has it close, Peltola near 56¢ and Sullivan near 47¢ as of August 16, 2026. Under ranked-choice voting the winner is not always whoever leads first choices, because eliminated candidates' second choices get redistributed, which is why the race is priced as a toss-up.
Can I trade the Alaska Senate race on OddsShopper? No. The race trades as event contracts on Kalshi, a CFTC-regulated exchange, and OddsShopper's odds tools cover the sports slate rather than election futures. What carries over is the method: reading a price as an implied probability, then asking whether the number is too high or too low.
