Big Brother 28 Final Four Odds: Dane Called Devens a Runaway Train. Drew's One Vote Has Kalshi Pricing Him 70% to Go

Melody is gone, Taylor won the Final Four HOH, Drew won the veto, and Drew now casts the only vote between Rick Devens and Dee Valladares. Kalshi has Devens 70–71¢ to be evicted tonight and 8–9¢ to win the season. Here is what the tape still supports and what it doesn't.

Big Brother 28 final four Kalshi odds, September 24 2026: Rick Devens 70 to 71 cents to be evicted by Drew Campbell's sole vote; season winner board Drew 39 cents, Dee Valladares 33 cents, Taylor Brown 17 cents, Rick Devens 9 cents.

Dane taped this one with Rick Devens holding the Head of Household and a 40¢ price to win the season. His word for him was runaway train. His worry was that nobody in the house had the numbers to stop him.

It turns out the house only needed one vote. Drew Campbell has it tonight.

Kalshi has Devens 70–71¢ to be evicted tonight by Drew's sole vote, and 8–9¢ to win the season — down from 46¢ on Tuesday morning. Drew, the houseguest Dane said "no one is going to give the vote at the end," is now the favorite at 38–39¢. Dane's tape went 2-for-2 on the Week 11 calls it made (Melody out, Taylor through). The Devens call comes down to one decision tonight at 8 p.m. ET. Two positions still follow from what he said: Drew to NOT win at ~62¢ if you trust his jury read, and Devens to win at 9¢ — lottery size only — if you trust his Devens read.

What happened since the tape?

Dane recorded this while Melody Morris was still the 86% favorite to go and Devens had not named his nominees. It was posted Wednesday afternoon, September 23. By then the house had played two full rounds:

Dane's two Week 11 calls both landed. Melody went. And Taylor did more than "slide through" — she survived as the replacement nominee, then won the HOH that started the Survivors' week on the block.

The one scenario Dane gave for stopping Devens was a women's alliance of Dee, Melody and Taylor. That did not happen. What happened instead was simpler: Taylor nominated, Drew held the veto, and a five-person game became a one-person vote.


What is the position tonight?

Market: Big Brother Season 28 · Thursday elimination (Kalshi · KXBIGBROTHERELIMINATION-26SEP24)

On the block: Rick Devens and Dee Valladares · Sole vote: Drew Campbell

Live board now: Rick Devens 70–71¢ to be eliminated, Dee Valladares 25–28¢

The read: the market expects Drew to evict Devens, and Dane's own tape explains why

Resolution: the live eviction, Thursday, September 24, 8 p.m. ET on CBS

Every number below is a Kalshi quote snapshotted at 10:20 a.m. ET on September 24, 2026, except Devens's season-winner price, re-checked at 10:34 a.m. ET after it moved. Nothing here is a projection.

Here is the part that makes tonight simple to read: Dane's case for Devens was the case for evicting him. "Devens would win sitting next to Drew," he said. Drew does not need to hear that from Dane. Live-feed reporting from Online Big Brother frames Drew's choice the same way: keep Devens and you are likely signing up for second. Devens's pitch runs the other direction — that he is the more loyal final-two partner and Dee is the one who beats Drew. The market does not believe that, and neither did Dane.

Thursday eliminationBidAskMid
Rick Devens70¢71¢70.5¢
Dee Valladares25¢28¢26.5¢
Melody Morris99¢100¢already evicted, awaiting settlement
Drew Campbell · Taylor Brownsafe (vote · HOH)

The two live contracts sum to about 97¢. Sum the board before you read any price on it — that has been the habit of this whole series, and here it says one Survivor is leaving tonight, not zero and not two.

Is there an edge in Devens-to-go at 71¢? Not at the ask. The Kalshi taker fee is 7% × price × (1 − price) per contract — about 1.4¢ at 71¢ — so the real entry is near 72.4¢ for a vote the board has had Devens favored to lose since Tuesday night. Fair, not cheap.

How fast did the winner board flip?

Five days ago this series was writing about Devens doubling. This is the reverse trip.

HouseguestSun., Sept. 20Tue., Sept. 22 (a.m.)Tue., Sept. 22 (p.m.)Now
Drew Campbell14¢12¢38¢38–39¢
Dee Valladares31¢20¢18¢32–33¢
Taylor Brown11¢22¢21¢14–17¢
Rick Devens42¢46¢19¢8–9¢
Melody Morrisevicted

Hourly Kalshi closes, 11 a.m. and 11 p.m. ET; "Now" is bid–ask at 10:20 a.m. ET Sept. 24 (Devens at 10:34).

Drew went from 10¢ at 5 p.m. ET Tuesday to 38¢ by 11 p.m. and has held there since. Devens was 46¢ Tuesday morning and has lost roughly four-fifths of that price. The last leg was this morning: Devens traded at 15¢ at 10 a.m. ET and at 2–3¢ by 10:13, on a burst of selling — while his eviction price barely moved — then bounced back to 8–9¢ by 10:34. Something reached the feeds or the traders this morning that moved the winner board and not the vote board. We cannot tell you what. Treat that as the most important caveat in this piece.


What is the winner board actually saying about Devens?

Divide each Survivor's winner price by their chance of surviving tonight, and you get the market's read on how each one does if they make the final three:

Survive tonightWin the season (mid)Win if they survive
Dee Valladares~73.5%32.5¢~44%
Rick Devens~29.5%8.5¢~29%

Same final three — Drew, Taylor and whichever Survivor stays — and the market gives Dee about half again Devens's chance from the same seat.

That is the direct opposite of Dane's tape. Dane's whole argument was that Devens has the best résumé in the house and wins sitting next to anyone. If you believe that, Devens-if-he-survives should be priced at least like Dee. At Dee's 44% conditional, Devens's winner contract would be worth about 13¢, not 8.5¢.

There is one reason the market might be right, and Dane names it himself. His video description says Devens took the $10,000 offer. Inside the house, someone pressed a button for $10,000 this season's final week; Drew and Dee suspect Devens, and production has not said who did it, per Online Big Brother's feed reporting. If the jury believes Devens took the money, that is exactly the kind of thing that turns a résumé into a grudge. It is the likeliest explanation for the gap — and we cannot verify it.


The two positions the tape still supports

1. Drew to NOT win the season — about 62¢. Dane's jury read on tape: "No one wants to give it to Drew." Drew's winner Yes bid is 38¢, so the No side costs about 62¢, plus a taker fee of about 1.6¢ — call it 63.6¢ all-in, paying $1 if Dee, Taylor or Devens wins. The market's own middle says 61.5%. This is worth owning only if your conviction that the jury won't pay Drew sits above roughly 64%. The catch: Drew is guaranteed the final three tonight and has the Final HOH in front of him, and a houseguest who wins the last HOH chooses his final-two opponent. Dane's read is about the jury. The price includes the path.

2. Devens to win the season — 9¢, lottery size. This is Dane's actual call, and it is now priced like a long shot, because it needs three things: Drew keeps him tonight (~30%), he reaches the final two, and the jury pays him. At the 9¢ ask plus about 0.6¢ in fees, a $10 position buys roughly 111 contracts that pay about $111 if he wins. If you think the 29%-vs-44% gap above is the market overreacting to the $10K story, this is how you say so. If you think the market knows something from the feeds this morning, you pass.

What is not a position: the Survivor basket. On September 19, Devens plus Dee cost about 74¢ all-in to pay $1 if either won. Tonight, one of them is almost certainly leaving. The basket now costs about 44¢ all-in (33¢ + 9¢ at the ask, plus ~2¢ in fees) — cheaper because it is worth less, not because it is on sale.

And no free lunch. Buying all four live winner contracts at the ask costs 39 + 33 + 17 + 9 = 98¢. Fees add about 4.8¢. That is 102.8¢ to collect $1 — the board is coherent in aggregate, and Taylor shows only 5 contracts at 17¢ before the ask steps up anyway.

Microstructure, for anyone entering size. Drew's book is deep on both sides — roughly 900 contracts offered at 39¢ against 1,300 bid at 38¢ — so the No side fills clean. Devens is thin: about 170 offered at 9¢ against 25 bid at 8¢ (10:34 a.m.), and this morning showed how fast a few hundred contracts move that price. Use limit orders at the bid. Do not chase.


What comes after tonight?

The schedule, per CBS as reported by Big Brother Network:

The winner board will reprice hard the moment tonight's vote is read. If Devens survives, his winner contract is the one that moves most — it is priced at 29% conditional, and it would stop being conditional. If Dee survives, the board is pricing that already.

Frequently Asked Questions

Who is favored to win Big Brother 28 right now?

Drew Campbell. As of 10:20 a.m. ET on September 24, 2026, Kalshi's season-winner market (KXBIGBROTHER-26DEC31) has Drew at 38–39¢, Dee Valladares 32–33¢, Taylor Brown 14–17¢, and Rick Devens 8–9¢ (re-checked 10:34 a.m.). Drew was 12¢ on Tuesday morning. He won the Final Four Power of Veto, used it on himself, and is now the only vote at the Final Four eviction.

Who is going home at the Big Brother 28 Final Four eviction?

Kalshi's Thursday elimination market (KXBIGBROTHERELIMINATION-26SEP24) has Rick Devens at 70–71¢ and Dee Valladares at 25–28¢ as of 10:20 a.m. ET on September 24. Those two are on the block and Drew Campbell casts the sole vote. The two contracts sum to about 97¢, so the board is pricing exactly one of them to leave. The eviction airs live on CBS Thursday at 8 p.m. ET.

How was Melody Morris evicted from Big Brother 28?

In a shortened eviction cycle on September 21, reported from the live feeds while they were dark for about three hours, which aired Wednesday, September 23. Devens had nominated Drew and Melody; Drew won the veto and used it on himself. Melody became the fifth juror. Dane had her as the 86% favorite to go on tape, and Kalshi's elimination contract for her trades at 99¢ pending official settlement.

Why is Rick Devens only 8–9¢ to win Big Brother 28?

Mostly because he is 70–71¢ to be evicted tonight — he can only win if Drew keeps him, which Kalshi puts near 30%. But even inside that 30%, the board is harsh: dividing his winner price by his survival price gives roughly a 29% chance to win if he survives, against about 44% for Dee if she survives, and they would be sitting in the same seat. Dane's video description says Devens took the $10,000 offer; the feeds have not confirmed who pressed that button. If the jury holds it against him, that is the likeliest reason for the discount.

What are the Big Brother 28 finale dates?

Per the CBS schedule reported by Big Brother Network: the Final Four eviction and the start of the Final HOH competition air live Thursday, September 24 at 8 p.m. ET (two hours); part one of the Final HOH fallout airs Sunday, September 27 at 9:30 p.m. ET; the 90-minute finale is Thursday, October 1 at 8 p.m. ET.

Is there value on the Big Brother 28 winner board?

Two positions still follow from Dane's tape. If you hold his jury read, Drew Campbell to NOT win costs about 62¢ plus a 1.6¢ taker fee and pays $1 if anyone else takes it — worth it only above roughly 64% conviction. If you hold his Devens read, Devens to win at 9¢ is a small lottery-sized position that needs Drew to keep him tonight. Nothing on the board is a free lunch: buying all four live winner contracts at the ask costs about 98¢ before fees and about 102.8¢ after them.
