Prediction market traders are now getting their say on the best AI of 2026, as we wait to find out, officially, which of our robot companions we like the most.
AI is already reshaping just about everything we do, and given the pace at which this technology is progressing, we can safely say that this is just the beginning. But with so many models to choose from, how do we know who is currently winning the AI war?
That's where Kalshi comes in. By allowing traders to put their money where their mouth is, it gives a realistic picture of each company’s chances, with prices and probabilities that change day by day.
Industry insiders share their opinions on the way artificial intelligence is heading all the time, but it’s prediction markets that give the clearest indicators of what we really think about the latest and greatest robot geniuses to launch.
Key Takeaways:
- Anthropic's Claude just survived yet another regulatory scare, maintaining its favorite status after the US government lifted the two week ban on Fable 5 and Mythos 5.
- Gemini’s momentum has slowed while traders wait to see if Google's can reclaim the multi-modal throne by December.
- ChatGPT is now in third place despite hitting a billion monthly app users in May. OpenAI now faces its own regulatory friction though. The launch of GPT-5.6 has been delayed at Washington’s request.
- It's not looking good for Grok. Its down to 8.6¢, which shows just how skeptical traders are about its ability to close the gap before the year ends.

Best AI Odds 2026: The Current State of the Board

Claude | ‘Yes’ 64.3¢
Anthropic remains the definitive market favorite, showing incredible resilience after a chaotic month. On June 9, Anthropic launched Claude Fable 5, only for the US government to step in three days later with an unprecedented emergency order.
Citing severe cybersecurity fears that foreign adversaries could use the model to mount devastating cyberattacks, Washington banned foreign nationals from accessing Fable 5 and its hyper-advanced sibling, Claude Mythos 5.
Anthropic responded by temporarily pulling the plug, but following intense, two-week collaborative security vetting with the newly minted US Center for AI Standards and Innovation (CAISI), the US government officially lifted the export controls on July 1, 2026.
With Commerce Secretary Howard Lutnick confirming that Anthropic’s new safeguards are "extraordinarily strong," traders have breathed a sigh of relief, locking Claude into its premium 64.3¢ slot (with a 'No' contract priced at 35.9¢).
Gemini | ‘Yes’ 14.4¢
It was looking like Google’s Gemini could be this year’s comeback kid for some time, but momentum has stabilized since.
Gemini sits in second place on the board at 14.4¢ (with a 'No' contract at 85.7¢). There’s no denying that Google is a company with the deep pockets and infrastructure required to turn that around, but traders are still cautious.
Unless Google unleashes a surprise model drop that captures the public's imagination the way Anthropic has, its probability is likely to stay in the teens.
ChatGPT | ‘Yes’ 13.9¢
OpenAI has managed to close the gap on Google, pulling within half a cent of the second-place slot.
On one hand, the consumer metrics are jaw-dropping: Sensor Tower data shows ChatGPT surpassed one billion monthly active app users in May. However, the market remains heavily skeptical of its technical edge over Anthropic.
In light of Anthropic's regulatory battle, OpenAI CEO Sam Altman confirmed that OpenAI has also delayed the full public launch of GPT-5.6 at the government's request, limiting it to a tightly vetted circle of partners.
At 13.9¢ for a 'Yes' share (and 87¢ for a 'No' share), traders are signaling that OpenAI’s era of dominance now faces massive challenges.
Grok | ‘Yes’ 8.6¢
If you’re looking for this market’s wildcard, it’s got to be Grok. Now in its 4.20 Beta phase, Grok has pivoted from being a light-hearted, witty chatbot to a far more serious competitor in this game.
Grok ranks highly in both real-time search and mathematical logic, but its price has dropped right down to 8.6¢ in recent weeks (from 16¢ in May), indicating serious skepticism about Grok’s ability to catch the frontrunners before December 31.
The Long Shots: Muse Spark, Qwen and Ernie
Bringing up the rear of the Kalshi board are the open-source and international giants. Meta's Muse Spark holds a slim 2.1¢, Alibaba's Qwen sits at 0.6¢ and Baidu's Ernie rests at a near-impossible 0.3¢.
While these models represent monumental engineering achievements, prediction markets are really doubting their chances of taking the top spot on the human-preference leaderboard by December 31.
Value Picks: Where the Money is Moving
With prediction markets, wins are found when traders successfully identify gaps between market-implied probability and a model’s real trajectory. These platforms are so responsive to breaking news that prices will often overcorrect in response to political headlines, and when that happens there are often opportunities to be found.
The ‘Yes’ Value Pick: ChatGPT | ‘Yes’ 13.9¢
While Anthropic looks incredibly strong right now, buying ‘Yes’ shares on ChatGPT at 13.9¢ offers an explosive potential return if OpenAI drops a monumental model update in autumn. Betting against OpenAI entirely at this price point might be discounting the company’s massive resources and user base a bit too much.
The ‘No’ Value Pick: Gemini | ‘No’ 85.7¢
With Gemini's momentum cooling off and its 'Yes' price hovering at 14.4¢, the 85.7¢ price for a 'No' share is a highly attractive proposition for risk-averse traders. If you believe Google has too much ground to catch up on the Arena leaderboard to dethrone Claude by December, this 'No' contract is a good way to secure a return.
When Will Anthropic Release Mythos?
Use Promo Code COVERS
Claude may well be ruling the leaderboard, but there’s another highly volatile market Kalshi traders are weighing in on: the launch of Claude Mythos.
The capabilities of Mythos have been sending shockwaves through the tech sector ever since its confidential preview leaked in April.
Capable of autonomously uncovering critical flaws across major operating systems, the model was deemed a massive security risk. But following the July 1 resolution of the White House export control crisis, the rollout timeline has completely shifted.
When Anthropic dropped Fable 5 on June 9, many traders expected a market payout. However, Kalshi clarified that Fable did not satisfy the criteria because the true Claude Mythos 5 remained tightly restricted to a hand-picked list of institutions under Project Glasswing.
With export controls now officially cleared by the Commerce Department, Anthropic has stated it plans to scale public access to Mythos-class models as soon as final deployment protocols are met. It’s left Kalshi traders scrambling to adjust their positions on the calendar.
Before December 1, 2026 | ‘Yes’ 18¢ | ‘No’ 84¢
Despite the government restrictions being lifted, traders have grown deeply cynical about a rapid summer commercial release. The price for a pre-December launch has plummeted to 15¢, reflecting fears that post-blackout safety protocols will keep Mythos in an enterprise bottleneck for months.
Before January 1, 2027 | ‘Yes’ 20¢ | ‘No’ 81¢
In early June, this contract was a lock at 90¢. But the release of Fable, followed by recent Washington drama, dropped that price right down to 20¢. For forward-planning traders, this is still a good value play though, because if Anthropic uses its new momentum to launch Mythos publicly in the next few months to boost its upcoming IPO valuation, these 20¢ contracts will skyrocket.
The Wall Street AI Race: Trading the Impending IPOs

The battle for AI supremacy has officially spilled over onto Wall Street. Both Anthropic and OpenAI submitted confidential draft S-1 prospectuses to the SEC at the beginning of June, positioning themselves for public debuts that could reach huge valuations later this year.
Traders are putting money on the next IPO prediction markets, along with key markets like the best AI of 2026, as they attempt to get ahead of the companies and correctly predict the timing of public listing announcements.
- OpenAI IPO Timing: Despite OpenAI stating it has no fixed timeline, the market currently favors a late 2026 debut. Contracts for an official announcement before October 1 are now sitting at 24¢, but there’s greater confidence in a pre-November launch.
- The Race to Debut First: The "First to IPO" market has turned into a major battleground. Anthropic is the favorite at 74¢, with traders betting that its traditional corporate structure will clear regulatory hurdles more easily than OpenAI's model. OpenAI is trailing as the 24¢ underdog at the moment.
Traders are now using markets like these as an alternative to tech stocks. They’re also hugely informative for those with contracts on markets like the best AI of 2026 and the number of tech layoffs we’ll see in 2026.
Keep an eye on any breaking news stories ahead of regulatory updates, because the smallest of rumors has the potential to flip prices on these markets.
How is the Best AI of 2026 Decided?
The best AI at any moment is a little subjective. For this market, however, the winner is determined by data from the LM Arena Leaderboard.
The AI that tops the leaderboard on December 31, 2026, will be named the best of the year. It doesn't matter if other models have spent prolonged periods at the top spot during the year.
What is the LM Arena Leaderboard?
The LM Arena Leaderboard, which is sometimes also referred to as the Chatbot Arena, is an open-source research project developed by LMSYS Org (Large Model Systems Organization), a research group from UC Berkeley.
Designed to evaluate the performance of Large Language Models (LLMs), the The LM Arena Leaderboard is often used to determine which models we prefer.
The data used to determine positions on this leaderboard is provided by tests on real human preference, rather than static automated checks. And its this real-world testing that’s key to why the leaderboard is now widely considered one of the most reliable metrics on how well models really perform in day-to-day usage.
How does the LM Arena Leaderboard work?
The leaderboard uses human evaluation methods to determine which AI models are most useful at any one time. This crowdsourced data is collected in a relatively simple but highly effective way.
- Step 1: Humans are presented with two answers to a given query, taken from two anonymous, randomly selected AI models.
- Step 2: They are asked to vote for the one they prefer, with options for Model A, Model B or a tie.
- Step 3: Once the vote has been cast, the person is then told which models the responses came from.
As responses are gathered, the platform compiles that information using the Elo rating system. If a model wins against a stronger opponent, it sees a higher increase in its ranking than it would if it had beat a weaker opponent. Similarly, models can see big drops in their rankings if they lose to a weak opponent.
The fact that this rating system relies on real prompts from humans, which can be enormously varied and are sometimes sparse on detail, means that it gives a much clearer picture of how models really perform in the wild than other metrics.
The platform is also seen as the most up-to-date measure of human preference, as it’s updated in real-time using new models as soon as they’re released.

How do Kalshi’s AI Prediction Markets Work?
Unlike traditional investing where you buy a stock and hope it goes up over years, prediction markets like Kalshi allow you to trade on specific outcomes.
Binary Outcomes: You buy a ‘Yes’ or ‘No’ contract. Each contract pays out exactly $1.00 if you are right and $0.00 if you are wrong.
Real-Time Reaction: Unlike a quarterly earnings report, these markets react instantly to breaking news. That could be a big announcement like a surprise model drop from Meta, or even something as simple as a new X post from Elon Musk.
The Flip Strategy: Many traders intend to buy ‘Yes’ on a model like Grok (9.3¢) in the hope that there’ll be a hype-driven price spike that takes the price over 30¢ before long. If that happens, traders will often sell before the year ends to lock in a profit, without waiting for the final result.
FAQs: The Race for Best AI of 2026
The Kalshi market specifically uses the LM Arena Leaderboard. It’s a blind battle where humans rank which AI response is better without knowing which model provided it.
According to the rules, if two models are tied in rank, the one with the higher Arena Score wins. If still tied, the one with more votes wins. If they’re still tied, the elder model takes the prize.
Not at all. The market stays open until December 31, 2026. There are plenty of model drops left that will shift prices as time goes on.
While Meta's LLaMA is incredibly popular, it is an open-source model. Historically, closed-source models (like Claude or Gemini) have held the very top performance spot because they run on massive, proprietary compute clusters that are harder to replicate in open-source versions.
