Which company has the best Math AI model end of July?
Google is the current leader on the relevant Arena math leaderboard, but the margin is thin and several major competitors are close enough to overtake it before month-end. I give Google a modest edge over a coin flip, slightly above the market price, because it starts from first place and still has room for a late July Gemini update.
Analysis
As of July 10, 2026, Google sits in first place on the Arena math leaderboard with gemini-3.5-flash-high at 1521±25. Anthropic is close behind with claude-fable-5 at 1517±38 and claude-opus-4-6-thinking also at 1517±11, which means Google’s current edge is real but not comfortable. The leaderboard is also crowded with other strong contenders just below the top tier, so a small shift in votes or a new model addition could change the order quickly.
Recent company news does not make the race less competitive. OpenAI launched GPT-5.6 on July 9, and Anthropic restored Fable 5 globally on July 1, both of which increase the odds of fresh competition showing up in the math rankings over the next few weeks. On Google’s side, the Gemini 3.5 family is still active and Google’s own model page continues to label Gemini 3.5 Pro as coming soon, which leaves open the possibility of a late-July release that could reinforce Google’s position.
My read is that the market’s 42% Yes price is a bit too low given that Google is already in first place, but the lead is narrow enough that this is far from a strong favorite. The most important question is not whether Google is competitive now, but whether it can avoid being displaced by Anthropic or OpenAI before the July 31 check. Because there is still enough time for a meaningful leaderboard shake-up, I would price Google as favored but vulnerable rather than secure.
Arguments
For
- Google already holds the top math rank, so it only needs to defend a lead instead of catching up.
- Google still appears to have room for an additional Gemini 3.5 rollout, and a stronger late-July release could cement first place.
Against
- The lead is tiny, with Anthropic’s top math entries only a few points behind Google, so normal leaderboard noise could flip the order.
- OpenAI’s GPT-5.6 launch and Anthropic’s Fable 5 restoration raise the odds that another lab lands a late-cycle model strong enough to beat Google.
Key drivers
- Whether Google ships Gemini 3.5 Pro or another math-strong update before the July 31 check.
- Whether Anthropic or OpenAI gets a new model onto the math leaderboard quickly enough to challenge the current order.
- How much additional voting volume accumulates before month-end, since more votes can reshuffle close scores.
Risk factors
- A new high-performing model could be added to the leaderboard and immediately jump ahead of Google.
- The current top three are packed closely enough that a modest score change could demote Google from first.
Scenarios
Best case
Google releases Gemini 3.5 Pro or another stronger math-focused model before July 31 and stays ahead of the pack through the final check.
Most likely
Google remains a top-two contender throughout the rest of July, but the lead stays narrow and the final outcome depends on whether one of the rival labs lands a late model or voting shift.
Worst case
Anthropic or OpenAI gets a late leaderboard surge, pushing Google to second or lower by the July 31 noon ET check.

Will a cabinet member be impeached?
AI97%MKT5%Edge+92Hidden Gem**Very likely Yes.** A sitting Cabinet member (Philippine Vice President Sara Duterte) is already being tried in the Senate impeachment court, which in the Philippines follows a House impeachment — so the factual threshold for “impeached” has effectively been met and the probability of at least one Cabinet member being impeached before 2027 is extremely high.

Best AI model on July 18?
AI13%MKT97%Edge-84HypedI think claude-opus-4-6-thinking is a clear underdog here. It is currently near the top of the leaderboard, but it is not the leader today, and the latest frontier releases make it more likely to stay around second or third than to reclaim first.
