Apple is expected to unveil the iPhone 18 Pro and iPhone 18 Pro Max in early September, likely on September 8 or 9. As anticipation builds, an intriguing possibility has surfaced: cases designed for the iPhone 17 Pro may also fit the upcoming iPhone 18 Pro.

One case manufacturer has already updated its packaging to list compatibility with both models, a detail shared by Mark Gurman on X. He noted that Best Buy is already stocking these dual-compatible cases in U.S. stores.

Adding weight to the claim, the CEO of another Apple accessory maker confirmed similar feedback from suppliers. When asked about the Pro Max variant, he indicated that the same cross-compatibility would apply—iPhone 17 Pro Max cases should fit the iPhone 18 Pro Max.

This contradicts earlier rumors suggesting both iPhone 18 Pro models would be thicker than their predecessors. Whether those rumors were inaccurate or current reports are speculative remains unclear. With only weeks to go, the truth will soon be revealed.
