Which companies will have a #1 AI model by December 31?
Google has a real but still limited path to the top spot by year-end. It would likely need a major model release and a quick leaderboard jump, so I see this as a low-probability outcome slightly above the current market price.
Analysis
Google is clearly competitive, but the current evidence does not show it leading the specific leaderboard that matters for resolution. The most recent context has Google models clustered near the top tier in some benchmarks, yet still behind Anthropic and sometimes OpenAI on the widely watched public rankings. Because the market resolves on the Chatbot Arena text leaderboard, Google does not need to dominate every benchmark; it only needs one model to reach or tie for first there by the end of the year. That keeps the event alive, but the current standing suggests Google is still chasing rather than setting the pace.
The main argument for a Google Yes outcome is that leaderboard positions can change quickly when a new flagship model lands. Google has substantial compute, strong model teams, and a clear incentive to push a late-cycle release that performs especially well in conversational preference testing. The fact that some Google models are already respectable on multiple public rankings means the company is not starting from a weak base. If Google can deliver a model with stronger reasoning, better instruction following, and improved human preference scores, the Arena can re-rank very fast, and a single standout launch could be enough.
The main argument against Yes is that Google is currently not close to #1 on this particular leaderboard, and the frontrunners are not standing still. Anthropic appears to have the strongest recent position across several benchmarks, and OpenAI remains a persistent threat to take or defend the top spot. With only a few months left in the year, Google needs not just improvement but a decisive leap that beats models already favored by the market and by current public rankings. That makes the probability meaningfully below fifty-fifty, and the market’s pessimism looks directionally correct even if Google’s underlying research momentum keeps the chance from being negligible.
Arguments
For
- Google has the resources and technical talent to produce a late-cycle model that could jump to the top quickly.
- Arena rankings are volatile enough that a single standout launch could overturn the current order.
Against
- Google is currently behind the leaders on the main public rankings, so it has a real gap to close.
- Anthropic and OpenAI are already strong enough that Google needs a clear breakthrough rather than a modest improvement.
Key drivers
- Google has enough research depth and compute to launch a model capable of a late-year leaderboard surge.
- The Chatbot Arena can re-rank quickly after a strong model release, so timing matters as much as current position.
- Anthropic and OpenAI are setting a high bar, which means Google must make a larger leap than a normal incremental update.
- The market will resolve on a single specific leaderboard, so one breakthrough model matters more than broader benchmark performance.
Risk factors
- Google may not ship a sufficiently strong new model before the end of the year.
- Even if Google improves, another company could still hold the top Arena spot when resolution occurs.
- Small leaderboard changes and evaluation noise can leave Google just short of first place.
- A strong showing on other benchmarks would not help if Google does not reach #1 on the exact resolution leaderboard.
Scenarios
Best case
Google releases a flagship Gemini model that dramatically improves conversational preference scores, quickly rises to first or ties for first on the Chatbot Arena text leaderboard, and holds that position through year-end.
Most likely
Google improves further and remains a top-tier contender, but Anthropic or OpenAI keeps the lead on the resolution leaderboard, leaving Google short of #1 by December 31.
Worst case
Google’s next releases are incremental, another company keeps the top Arena position, and Google finishes the year still outside the #1 slot.

Will Anthropic flip BTC by December 31?
AI2%MKT77%Edge-75HypedAnthropic flipping Bitcoin by the end of 2026 looks extraordinarily unlikely. The valuation gap is so large that it would likely require a once-in-a-generation private funding event for Anthropic and a major Bitcoin drawdown at the same time.

"Spider-Man: Brand New Day" total domestic gross by August 31? (Higher Strikes)
AI25%MKT84%Edge-59HypedMy read is that Spider-Man: Brand New Day is more likely to finish above 900M domestically by August 31 than below it. I put the chance of less than 900M at about 25%, because the film is already so far along that only an unusually sharp slowdown would keep it under the line.
