Saudi Arabia
3.4% annual new-conflict probability
How to read these probabilities: Scores estimate the probability of a new armed conflict starting within the next 12 months. Ongoing conflicts can have a saturation effect, reducing the modelled probability of an additional conflict onset. A low or falling score does not imply less severe ongoing fighting or a safer country.

Risk assessment
Risk profile
The 12-month probability of a new armed-conflict onset in Saudi Arabia is 3.4%, a moderate risk. Saudi Arabia has substantial economic and military capacity, strong state institutions, and extensive security resources, which constrain the likelihood of sustained internal violence or a successful invasion. However, its position beside Yemen and its history of cross-border conflict with the Houthis leave the kingdom exposed to escalation.
Recent reporting describes intensified Houthi attacks on Saudi airports and oil infrastructure, alongside wider fighting in Yemen. Egypt pledged on October 18 to provide necessary support, while GCC governments condemned the attacks; the United States also warned of drone and missile threats to American interests. These developments involve Saudi Arabia, the Houthis, Egypt, GCC states, and potentially wider regional partners.
The largest uncertainty is whether attacks remain intermittent strikes linked to the Yemen war or develop into sustained fighting on Saudi territory. Risk would rise if Houthi operations caused major casualties or infrastructure damage, prompted a Saudi ground intervention, or widened through regional deployments. It would fall with a durable Saudi-Houthi de-escalation and reduced cross-border attacks.
Strategic reasoning
- Saudi Arabia’s state capacity, security apparatus, and financial resources make internal rebellion or prolonged domestic conflict difficult, while its Yemen border and prior Houthi confrontation provide a persistent pathway to external escalation.
- The strongest current escalatory signal is repeated Houthi targeting of Saudi airports and energy infrastructure. Egyptian and other regional support may strengthen Saudi defences, but additional deployments could also widen the conflict.
- The relevant risk is a new, sustained onset on Saudi territory, not fighting already underway in Yemen or isolated attacks that do not develop into continuing armed violence inside the kingdom.
Critical indicators
- On October 18, Egypt’s presidency pledged “all necessary and possible forms of support” for Saudi Arabia, and its security bodies considered authorising troops abroad. Reporting described any Egyptian role as strictly defensive, but the move shows regional mobilisation around Houthi attacks.
- On October 16, the U.S. mission in Saudi Arabia issued a Level 3 travel advisory citing drone and missile threats from Iran and the Iranian-supported Houthis, as well as armed-conflict risks. This confirms the exposure of U.S. and Saudi-linked sites without by itself establishing a new sustained conflict onset.
- Prediction markets priced the chance of the Houthis entering Saudi Arabia by October 31 at 6.5% on Polymarket, while a partial-scope market placed the chance of an effective ceasefire by that date at 11.3%. These contracts provide separate context and do not define the 12-month event.
