Total Internet Blackout in Iran by 2026?

Platform comparison

Market context

Polymarket prices this contract at **0% YES**, so the market is effectively saying a Cloudflare-measured total blackout in Iran is not expected before 31 August 2026. On Polymarket, buyers and sellers back that view with **USDC** on **Polygon**, and the contract settles via **conditional tokens** against the specified Cloudflare Radar threshold, so the relevant question is not whether Iran has “poor internet” but whether total bytes fall to **1.0% or less** of the four-week peak for **six straight hours**.

Iran has shown that it can and does impose very severe shutdowns when domestic unrest or external conflict escalates. During the 2019 protests, authorities cut off international access for roughly a week, with traffic dropping to effectively zero, and in January 2026 a nationwide blackout began amid protests and became one of the longest recorded. More recently, reporting in April and May 2026 said Iran’s wartime internet shutdown was still near-record length, with global connectivity around 1% of normal at times, which matters because this market’s trigger is calibrated to capture only the most extreme end of that pattern.[6][7][10][12][15][16]

For traders, the main catalysts are not routine technical outages but **security decisions**: protest waves, military escalation, and any official move by Iran’s communications or security apparatus to throttle or cut external links. Watch for state announcements, mobilisation or unrest around political dates, and any further changes in the war/security environment, because those are the moments when Iran has previously moved from throttling to near-total isolation.[2][8][13][16] If a shutdown does occur, the contract only pays out if Cloudflare Radar’s Iran chart shows the required six-hour run below the 1% threshold, so short spikes or partial throttling would not be enough.
