Israel and Saudi Arabia are in contact through US CENTCOM to provide Saudi Arabia with intelligence assistance against the Houthis, N12 journalist posts

The sourcing matters here: a single journalist's social media post, carried by one Israeli outlet, is the thinner end of regional reporting and has historically been as often walked back or denied as confirmed, so confirmation from either government or from US officials is the first tell. The operational significance, if accurate, is de-escalatory rather than escalatory in the first instance: intelligence sharing against the Houthis is defensive in character and aimed at protecting shipping lanes and Saudi infrastructure, the channel through which such episodes have tended to transmit into crude via freight rates, insurance premia and any disruption to transit rather than outright supply loss. The wider read-across is what it implies about the state of Saudi-Israeli relations under US sponsorship; past episodes of disclosed cooperation have occasionally complicated diplomatic tracks, and any Riyadh denial would be its own signal. Watch for official statements from the three capitals and for whether Houthi targeting of shipping escalates in response to the disclosure.
