Odds by venue

Consensus blends each venue’s last price, weighted by how much has traded there. Best Yes price is the cheapest ask across venues, and the payout is what a winning $100 stake returns before fees. Open a row for each venue’s contract name, bid and ask, and how closely their rules match.

About this market

Live prediction market odds for "Will a Chinese company have the best AI model by December 31?". Anthropic leads at 77%. Next is 3 at 23.5%. $1.5M has traded across 11 outcomes on Kalshi and Polymarket. The market is expected to resolve by Jan 1, 2027.

This market will resolve to "Yes" if a Chinese company owns the model that has the highest arena score, based on the Chatbot Arena LLM Leaderboard (https://lmarena.ai/) when the table under the "Leaderboard" tab is checked at any point between market creation and December 31, 2026, 11:59 PM ET. Results from the "Score" column under the "Text Arena | Overall" Leaderboard tab at https://lmarena.ai/leaderboard/text with style control off will be used to resolve this market. Chinese Companies include but are not limited to Alibaba, ByteDance, Baidu, Moonshot, Z.ai, DeepSeek, Meituan, Xiaomi, StepFun, Tencent, and MiniMax. Companies not headquartered in China or not primarily owned or operating within the Chinese technology ecosystem are not considered primarily Chinese. Models will be ranked by their arena score at the market’s check time. This market resolves to “Yes” only if a Chinese company’s model holds a strictly higher score than all others; ties will not qualify. The resolution source for this market is the Chatbot Arena LLM Leaderboard found at https://lmarena.ai/. If this resolution source is unavailable at check time, this market will remain open until the leaderboard comes back online and will resolve based on the first check after it becomes available. If it becomes permanently unavailable, this market will resolve based on another resolution source.

Questions

What does the consensus price mean?

It is the price of a Yes contract that pays $1 if the outcome happens. A 14¢ price means traders put the chance near 14%. Where two venues list the same outcome, we blend their last prices, weighting the venue with more trading volume more heavily (neither counts for less than a quarter). When only one outcome can win, each venue’s prices add up to a little over 100% (its margin); the fair chance removes that margin so the outcomes add up to exactly 100%.

How is the payout worked out?

A Yes contract pays $1 if it wins, so at the best ask a $100 stake buys 100 ÷ ask contracts. At 18¢ that is about 555 contracts, paying $556 (5.56x) if Yes happens. Venue fees and price slippage on larger orders are not included.

Why do the venues show different prices?

Each venue has its own traders, fees and order book. Contracts can also settle on slightly different terms, which is why each row lists how closely the rules match.

Is a price gap an arbitrage?

Only when you can buy Yes on one venue below what someone pays for Yes on the other, after fees, and both contracts settle the same way. We show the executable bid and ask so you can check.

How fresh are these prices?

Venue prices refresh every few minutes, and the order book and live quotes stream continuously. Each venue’s card shows when we last observed it.
