Two Prediction Markets Price Bitcoin's Chance of Reaching $100,000 This Year. One Says 14 Percent, the Other 9.

By Kresmion Research, July 15, 2026

Ask a prediction market how likely Bitcoin is to reach 100,000 dollars before the end of this year, and the answer depends on which market you happen to ask. On Kalshi, the regulated US exchange, the contract that pays out if Bitcoin touches 100,000 dollars at any point before December 31 was quoted at 14 to 15 percent on Wednesday morning. On Polymarket, the offshore venue that lists the same question, it was 8 bid, 10 offered, and last traded at 9. Same coin, same deadline, same payout, and a gap of about five points, which puts Kalshi more than half again as high as Polymarket.

This is a note about that gap and what it is made of. It is not a forecast about where Bitcoin goes, and it is not advice. The point is narrower and stranger: two of the largest places people bet real money on Bitcoin's price are looking at the same event and quoting it differently, and the difference has held since Tuesday afternoon.

The same bet, two different prices

Both venues run a ladder of these contracts, one for each round number. Each one asks the same thing: will Bitcoin trade at or above this level at any point before the end of 2026. Bitcoin was near 64,700 dollars on Wednesday morning, up about 3 percent after Tuesday's softer than expected inflation report, so every rung on the ladder is a bet on a move still well above the current price. The 100,000 dollar rung is a bet on roughly a 55 percent gain by year end.

Kresmion pulled both ladders live from each venue's own price feed at about 08:52 UTC on July 15. The figures below are the midpoint of each market's bid and ask.

Kalshi is the richer market on every rung. The gap is widest at 100,000 dollars, where the two venues are about five points apart, and it narrows toward the higher strikes, down to about one point at 150,000 dollars. A single mispriced contract would be noise. The same tilt running across all six rungs at once is a pattern, and it is the same pattern Kresmion's own cross venue monitor recorded through Tuesday evening and into Wednesday, so it has held for roughly fourteen hours rather than flashing up on one pull. You can see the current cross venue quotes on the Kresmion odds page, alongside the underlying Bitcoin data.

Why the two prices can drift apart

The reason a gap like this can exist at all is that the two markets are walled off from each other. Kalshi is a US exchange regulated by the CFTC, its users are identity verified, and they trade in dollars from US bank accounts. Polymarket settles in a stablecoin, runs offshore, and is closed to US persons. A trader who thinks Kalshi's 14 percent is too high and Polymarket's 9 percent is right cannot easily sit on both sides, because getting money and identity across that regulated to offshore boundary is the whole friction. Nothing mechanical forces the two prices together, so they do not have to agree.

The contracts are also not identical down to the last detail, which gives the prices a second reason to sit apart. Polymarket settles on Binance's one minute high for Bitcoin against the dollar stablecoin. Kalshi settles on the CF Bitcoin Real Time Index, a composite that blends several exchanges and trims the extremes. Polymarket's touch window opened in late November 2025 and Kalshi's in early January 2026. None of those differences is large, and importantly none of them points the way the gap actually runs. A single exchange one minute high is, if anything, the easier of the two conditions to trip, and a longer window is the easier to satisfy, so both would tend to make Polymarket the pricier leg. Polymarket is the cheaper one. The contract terms explain why the two prices need not be equal. They do not explain why Kalshi is the higher of the two.

Why Kalshi is the richer side

What is left, once arbitrage and contract terms are set aside, is who is doing the betting. The marginal buyer of a 14 cent ticket that pays a dollar if Bitcoin reaches 100,000 dollars is paying up for a long shot, and long shots are exactly where retail money tends to overpay. That behavior is well documented in betting markets, and Kalshi's book is a US retail book. Polymarket's pool skews more crypto native and prices the same far off outcome lower. Segmentation is what lets the gap survive. The difference in who trades on each venue is what sets its direction.

The practical consequence is simple. There is no single market implied probability that Bitcoin reaches 100,000 dollars this year. There are two, 14 percent and 9 percent, and which one gets quoted in a headline is a choice about which venue you read. The spread between them is a live reading of how separated the regulated US and offshore crypto betting pools have become. It says more about the plumbing of these markets than about where Bitcoin is headed.

The strongest evidence against this read

The hardest objection is that the gap is not tradable, so it may not be telling you much. Kalshi's 100,000 dollar contract turned over only about 1,300 dollars in the last day, and the resting bid at the top of its book is on the order of a hundred contracts. A price that thin can be stale between trades, and a reader who trusts only deep, liquid quotes would say the 14 percent is soft. There is a fair answer and a concession inside it. The answer is that the contract is not empty: it carries about 285,000 dollars of open interest, its price barely moved between Tuesday and Wednesday, and the tilt shows up on all six rungs and across fourteen hours, none of which a random thin print would produce. The concession is that you cannot put real size through the gap. This is an informational divergence: a fact about how the two crowds price the same far off outcome. You cannot trade it in any size.

What would change the read

The clean test is time. If the gap closes over the next few sessions, with Polymarket drifting up toward Kalshi or Kalshi easing down toward Polymarket, then it was liquidity noise and there is nothing structural here. If it holds across several days the way it held across Tuesday night, the segmentation read stands. A Bitcoin move back toward 100,000 dollars would be the real stress test, because that is when the two crowds would either pull apart further or get dragged together by traders finally bothering to work the spread. And it is worth watching whether the same Kalshi over Polymarket tilt appears on other markets both venues list. If it does, this is about who trades where. If it is only Bitcoin's high rungs, it is about this asset.

Key takeaways

Frequently asked questions

Why do two prediction markets show different odds for the same Bitcoin price?

Because the two markets are separated and cannot arbitrage each other. Kalshi is a US regulated exchange that trades in dollars and verifies identity; Polymarket is offshore, settles in a stablecoin, and is closed to US persons. A trader who thinks one price is wrong cannot easily take both sides, so nothing drags the prices together. On top of that the two venues attract different crowds, and the contracts settle on slightly different price feeds, which gives the quotes further room to sit apart.

Which number is correct, 14 percent or 9 percent?

Neither is more official than the other. Each is the price at which real money is willing to trade that contract on that venue right now. The useful way to read them is as a range set by two different crowds, about 9 to 14 percent that Bitcoin touches 100,000 dollars before the end of 2026, with the regulated US venue at the high end and the offshore crypto venue at the low end.

Can you make money on the gap between the two markets?

Not in any size. In principle you would buy the cheaper Polymarket contract and sell the richer Kalshi one, but Kalshi's 100,000 dollar market traded only about 1,300 dollars in the last day and its resting orders are tiny, so there is almost no depth to trade against. The contracts also settle on different price feeds, which adds risk to any hedge. The gap is worth watching as information, not as a trade.

What is the single most important caveat?

Liquidity. The Kalshi side of this gap is very thinly traded, which is why the divergence is best read as a fact about how the two crowds price the same outcome rather than as a signal about Bitcoin itself. Kresmion carries the persistence and the open interest precisely so the thin daily volume is not mistaken for a fresh, deep quote.
