CoreWeave downgraded by Moody's or S&P by...?
CoreWeave looks financially stressed enough that a downgrade is plausible, but the market is still asking whether Moody’s or S&P will take formal action before year-end, which is a much narrower and less certain event. I put the odds of Yes modestly above the market price because the credit metrics and trading levels are consistent with meaningful downgrade risk.
Analysis
CoreWeave’s reported ratings are already below investment grade, which means there is less cushion before agencies decide that further deterioration warrants another cut. The company’s debt and equity market signals are clearly weak: CDS has moved into distress territory, bond yields have spiked, and traders appear to be pricing the debt closer to deep-distress credit than to the formal ratings level. That kind of gap between market pricing and agency ratings often creates pressure for a downgrade if the underlying fundamentals do not stabilize quickly.
At the same time, the event is not asking whether CoreWeave remains risky, but whether an agency will publish a formal downgrade by December 31, 2026. Rating agencies tend to move deliberately and usually want clear evidence that liquidity, leverage, refinancing access, or operating performance has worsened beyond what was already incorporated. The presence of a strong backlog and management confidence could give agencies a reason to wait for more data rather than react immediately to bond volatility alone.
The market-implied probability at 21% looks somewhat low given how stressed the credit appears, but it is not irrational because a lot must happen for this to resolve Yes. CoreWeave could stabilize through continued demand for AI infrastructure, support from contract revenue, or successful funding execution, and that would reduce the urgency for a rating action. Still, if the company continues to trade and fund itself like a much weaker credit than its current ratings imply, the agencies may eventually catch up before year-end.
Arguments
For
- Arguments for Yes: The company’s market pricing already looks far weaker than its current ratings, which increases the odds of a catch-up downgrade.
- Arguments for Yes: Distressed spreads and high bond yields suggest that rating agencies may soon need to reassess CoreWeave’s leverage and refinancing risk.
Against
- Arguments against Yes: Moody’s and S&P often move only after clear fundamental deterioration, not just because the bonds are trading badly.
- Arguments against Yes: The company still has supportive narrative elements like backlog and AI demand, which may delay a formal downgrade.
Key drivers
- CoreWeave already sits in speculative-grade territory, so a small deterioration could trigger another formal downgrade.
- Severe bond and CDS weakness increases the chance that Moody’s or S&P revises ratings to reflect stressed financing conditions.
- A formal downgrade is more likely if leverage, liquidity, or refinancing prospects worsen over the next two months.
- The existing backlog and continued AI demand could convince agencies to wait and avoid an immediate action.
Risk factors
- Rating agencies may decide that current ratings already reflect the company’s risks and wait for more evidence.
- Strong contract demand or fresh financing could stabilize credit metrics enough to prevent a downgrade by year-end.
Scenarios
Best case
CoreWeave stabilizes its funding profile, continues to execute on contracted demand, and the agencies keep ratings unchanged through December 31.
Most likely
CoreWeave remains under pressure but does not receive a formal downgrade before the deadline, with agencies waiting for more concrete evidence of deterioration.
Worst case
Credit conditions worsen further, refinancing risk rises, and either Moody’s or S&P issues a downgrade before year-end.

Carles Puigdemont back in Spain by...?
AI8%MKT59%Edge-51HypedThe most likely outcome is No, because the key legal change enabling a return appears to have landed after the market deadline and the latest reporting points to any actual return happening only after the November election. A Yes outcome would require Puigdemont to have physically re-entered Spain before October 15, 2026, with no clear evidence that he did so.

Papertrade FDV above ___ one day after launch?
AI84%MKT52%Edge+32Hidden GemThe evidence strongly favors Yes because reported token pricing and supply metrics imply an FDV far above $25 million, and even conservative readings still clear the threshold by a wide margin. The main uncertainty is not valuation magnitude but whether the token met the market’s exact launch and tradability conditions at the settlement time.

Israel Election: Likud # of seats?
AI58%MKT36%Edge+22Hidden GemLikud is hovering right on the cutoff, but the recent polling pattern leans slightly toward fewer than 20 seats. I would price a modest majority chance on Yes because multiple recent surveys sit at 18 to 19, even though 20 remains very plausible.
