Terms like brainrot and larping are leading the field at the moment, but vibe isn’t far behind. Traders are still miles from backing a single favorite on this prediction market, though. At the current prices, we’ve got implied probabilities ranging from 7% to 13% for the top contenders.
Price movements in this market remain fluid, though. Historically, Merriam-Webster releases its official Word of the Year in late November or early December, so there’s plenty of time for the market to make its decisions.
The most important thing to note before making your selections, is that the lexicographical team bases its final decision on search volume spikes on Merriam-Webster.com. It’s not about the words most used on social media, or the ones you hear most often in daily life. It’s the ones people hear enough to look them up.
Keep an eye on national news stories and any sudden cultural shifts throughout the autumn, as media connections to certain words can dramatically increase search queries on the site. A single viral story could change the whole board.
Value Picks: The Best Profit Potential on the Word of the Year Board
The most successful prediction market traders are those that can spot any discrepancies between a market’s implied probability of an outcome, and the realistic chance that it might happen.
On a board like this one, that’s far from simple. But there’s data we can use to help inform decision-making on even the most niche of prediction markets.
Here are some of the top picks for traders looking to put money on the word of the year, in terms of profitability potential and possible flip opportunities.
'Semiquincentennial' | 'Yes' 9¢
This year marks the 250th anniversary of the United States, which is why we’ve got 'semiquincentennial' on the board for 2026.
Semiquincentennial is a complex word and it’s tricky to spell, and that generates plenty of search queries as users look it up after hearing it cited in major official events. At 9¢ for a 'Yes' contract, this is a historic national milestone that looks underpriced at the moment.
'Vibe' | 'No' 93¢
Traders backing this one may well be relying on vibes alone. The better option is the ‘No’, even at the high price of 93¢.
Now, there’s no denying that vibe is a word that crops up in daily conversation more often than it really should, but realistically, users aren’t going to be looking this one up in the dictionary enough to make it word of the year. We all know what vibe means, don’t we?
'Agentic' | 'Yes' 4¢
Tech jargon has entered the conversation. As artificial intelligence gets ever more powerful, our fascination with it just keeps on growing. So much so, that we’re inventing entire new words to talk about the wonders of this modern technology.
Generalized terms like ‘AI’ have now faded into background noise, but the word ‘agentic’ could be worth considering. It offers high risk-to-reward potential at 4¢, and we can definitely see professionals looking up the technical definition of this one.
'Brainrot' | 'No' 89¢
As the powers of AI grow, so too does the amount of brainrot we’re subjected to on a day-to-day basis. This word emerged relatively recently, but we’re hearing it used more and more (often in connection with AI slop and other addictive online content).
It’s entirely possible that users might look up the definition of this word, but don’t be hasty in backing it at this early stage. Internet slang like this rarely sustains the broad crossover volume required by Merriam-Webster, unless of course we also get some kind of mainstream media focus. So, if there are any brainrot related news stories in the coming months, this could change.
'Performative' | 'Yes' 4¢
Public figures can’t do much without being labelled performative, so this word tends to crop up fairly regularly too. It’s a longshot at 4¢, but there are lookup spikes whenever political figures and celebrities are accused of superficial gestures.
At the current price, traders give the word ‘performative’ a 2% implied probability of taking the win. The profit potential is huge, but it’s a risky pick right now.
Expert Insights: Predictions for Word of the Year 2026
To get a better understanding of how social media hype translates to dictionary lookup spikes, we spoke to language experts about the spread of internet slang, and why some terms stick while others fade.
The rapid spread of online language comes down to continuous exposure through digital platforms. As Ben Walker, CEO of Ditto Transcripts, explains:
"When videos go viral on platforms like TikTok or Instagram, millions of people hear the exact same phrases spoken over and over again until they start using them without even realising. This is called accommodation, where people subconsciously start adjusting the way they speak to match what they are constantly hearing."
Madeline Enos, language trends expert at Preply, highlights how quickly niche terms break out into the mainstream:
“Slang gives us a fascinating snapshot of how culture and language evolve. Terms can move from niche online communities into wider conversation remarkably quickly.
One moment people are discovering ‘6-7’ and ‘rage bait’, and soon after, terms like ‘brainrot’ and ‘larping’ are appearing across social media.“
Decoding Key Contenders: Brainrot, LARP and Vibe
Slang terms might seem to be everywhere for a while, but usually interest in words like this is short-lived. But for a market like this one, we need to be able to spot the ones with better potential for longevity. That long-term interest usually depends on their utility, say our experts.
On the examples of brainrot and vibe, Walker notes:
"Words like ‘vibe’ and ‘brainrot’ have become so popular because of their simplicity. They are basically shorthand versions for explaining things that used to require more articulation."
"'Brainrot' is a good example of this because instead of explaining that your mind feels fried from scrolling on your phone for hours, you could just say 'brainrot' and everyone knows what you mean."
Some terms originate from acronyms, like larping for example. As Enos explains, “The phrase ‘LARP’ is originally derived from the acronym meaning Live Action Role Play, a hobby where individuals dress up and act out fictional scenarios.
Now, ‘LARP’ has evolved and become a prominent fixture in internet slang, showing how quickly a niche acronym can enter everyday lingo.
Formal Terminology vs. Fleeting Trends: 'Semiquincentennial'
Prediction market traders often lean toward high-visibility slang on markets like this one, but in the case of Word of the Year 2026, it could also be worth considering some of the more formal terms on the board.
As Enos explains, “‘Semiquincentennial’ is a formal word, referring to the 250th anniversary celebration of the Declaration of Independence.
With America’s Semiquincentennial passing on July 4th 2026, worldwide searches for the phrase spiked by 833% over the previous year, hitting 20,000 searches in July. The rapid adoption of this phrase is a perfect demonstration of how language can become popularised by major cultural and historic events.”
The resurgence of formal terms like this could also be another trend in language, as some fight back against the rise of simplistic internet slang.
Walker notes, "Some people use overly simple shortcuts like 'brainrot,' and other people who perhaps don’t want to use as much slang in their vocabulary are starting to use overly complicated words that you never used to hear, like ‘semiquincentennial’. In both cases, certain language is being made popular by social media..."
How Do New Words Get Into the Dictionary?
Some of the newer words on the board could be destined for the dictionary before long. While they might look just like simple slang, words like these can easily be added to the dictionary following real-world adoption.
Over the past few years, we’ve seen it happen with words like ghosting, selfie and stan, all of which were popularised via social media.
“This is exactly how language has always expanded and developed, except it is just happening much faster with the help of social media,” explains Walker.
"There is a slang term for almost everything now, which started online and have leaked into everyday conversations, and if people keep using these words out loud to describe something that no other existing word can, dictionary publishers like Merriam-Webster or Oxford eventually take notice.

Word of the Year 2026 FAQs
Merriam-Webster determines its winner by analyzing real-time search query data on its website throughout the calendar year. Rather than holding a public vote, editors track terms that experienced massive spikes in lookups compared to previous years. These spikes are typically driven by major news events, technological shifts, or broader cultural conversations.
Contract prices on Kalshi represent the market-implied probability of a word winning the official title. For example, a 'yes' contract trading at 14¢ indicates a 14% market chance of resolving as the winner. Each binary contract settles at exactly $1.00 if the outcome is correct and $0.00 if incorrect.
The market officially resolves when Merriam-Webster publicly announces its official Word of the Year selection. This anticipated announcement traditionally takes place in late November or early December each year. Settlement on Kalshi is verified directly against official press statements released on the primary Merriam-Webster website and news distribution channels.
Yes, traders can exit their market positions at any point before the final announcement occurs. If news causes a word's 'yes' contract price to increase, you can sell early to lock in gains. This feature allows active market participants to capitalize on temporary price swings without holding positions until December.
Slang terms often command higher early prices due to high social media visibility and trader retail sentiment. However, official dictionary selections depend strictly on lookup volume rather than social popularity. Words like 'semiquincentennial' often present strong value because readers actively look up their exact definitions during major national news events.
