DeepSeek market share this week
DeepSeek looks meaningfully more likely than not to clear the 22.9% threshold, with the latest OpenRouter snapshots sitting above that line and showing it near the top of the leaderboard. I estimate a 67% chance of Yes, well above the current market price.
Analysis
The strongest signal is the recent OpenRouter evidence itself: multiple seven-day snapshots put DeepSeek around 24.4% and describe it as the leader or near-leader in text market share. That is a comfortable cushion above the 22.9% cutoff, and when a model is already several points above the trigger, the default expectation should be that it stays above unless there is a sharp late-period routing reversal. The cited product momentum from V4.1 Flash and continued developer usage support the idea that this is not just a one-day spike but part of an active share trend.
The main argument against Yes is timing and methodology. This contract resolves on the Monday weekly update for the week of Oct. 5, and weekly market-share windows can move materially if large customers reroute traffic near the end of the period. OpenRouter share is also a relative metric, so DeepSeek can lose ground even without absolute demand falling if another model surges. That said, the most recent available read is still above the threshold, which means the burden of proof is on a meaningful late-week deterioration rather than on continued stability.
Compared with the current market price, the 19% Yes probability looks too low. The market is pricing in a very large chance that DeepSeek falls below 22.9%, yet the public signals point to a model that has recently been above 24% and is still described as the leader. I would expect some discount because weekly shares can be noisy, but not enough to justify such a steep gap unless there is private evidence of a late decline that has not shown up in the latest snapshots.
Arguments
For
- Recent seven-day readings place DeepSeek above the cutoff with a modest but useful buffer.
- Developer adoption signals from the V4.1 Flash release suggest continued token-volume support into the resolution window.
Against
- Weekly market-share numbers can swing enough that a currently above-threshold reading is not guaranteed to hold.
- The market share is competitive and dependent on other providers' performance, which adds noise to the final weekly update.
Key drivers
- Recent OpenRouter snapshots show DeepSeek at roughly 24.4%, which is above the 22.9% resolution threshold.
- DeepSeek appears to be leading the provider leaderboard, suggesting sustained routing demand rather than a fleeting spike.
Risk factors
- A late-week shift in routing could pull share below the threshold before the Monday update is finalized.
- OpenRouter share is relative, so gains by competing models can cause DeepSeek to miss even if its own usage remains strong.
Scenarios
Best case
DeepSeek maintains its recent momentum, finishes the week near or above 24%, and the Monday OpenRouter update confirms a clear Yes.
Most likely
DeepSeek lands modestly above the threshold, with the final update showing a result in the low-to-mid 24% range and resolving Yes.
Worst case
Late-week rerouting or a competitor surge drags DeepSeek below 22.9% in the official weekly update, producing a No.

Next Prime Minister of Serbia?
AI32%MKT67%Edge-35HypedAleksandar Vučić is still a highly dominant figure in Serbian politics, but becoming the next officially sworn-in prime minister would require a notable reshuffle away from his current presidential role. I think the market is pricing his personal control too aggressively, and the more likely outcome is that someone else becomes prime minister first.
