Oil prices slumped and U.S. equities surged on Sunday after Washington and Tehran signaled an interim peace accord. Brent crude tumbled 4.8% to $83.17 a barrel, while the Nasdaq jumped 3.1%, the S&P 500 rose 1.7% and the Dow added 0.9% (about 469 points). Traders trimmed bets on further rate hikes, seeing a 55% chance of a Fed move this year, down from 70% a week earlier.

The market rally also reflected optimism that the Strait of Hormuz could reopen on Friday, a development President Trump linked to the pending deal. A reopening would ease shipping bottlenecks and dampen inflation pressure, reinforcing the recent slide in rate‑rise expectations. Meanwhile, AI startup Anthropic faced a federal class‑action suit alleging it misled premium users about usage caps.

Fox announced a $25 billion cash deal to buy Roku, the leading streaming platform for connected TVs. Fox shares plunged 17%, making the stock the worst performer on the S&P 500, while Roku’s valuation could boost Fox’s ad‑supported services such as Tubi. The transaction underscores a broader push by traditional media firms to secure scale in the fast‑growing streaming arena.
