Total Internet Blackout in Iran by 2026?

Platform comparison

Market context

Iran has already shown that its authorities are willing to impose very deep, nationwide internet restrictions when protests or military escalation are seen as a security threat. The strongest precedents are November 2019, when connectivity was cut for roughly a week, and the January 2026 protests, when Cloudflare and other monitors saw traffic fall to near zero; by the spring 2026 war-related shutdown, access had been held at about 1% of normal levels for an extended period before partial restoration began in late May.[1][14][10][11]

For this market, the key question is not whether Iran can shut the internet down, but whether there is another episode severe enough to meet the Cloudflare threshold for six straight hours before 31 August 2026. That means traders should watch for signs of fresh domestic unrest, military escalation, or a government security order, because past shutdowns have followed those triggers closely.[1][17][16] Recent reporting also shows that access has been restored only gradually after major outages, suggesting that a return from a near-blackout can be slow once authorities have decided to cut connectivity.[10][8]

The present 0% implied probability sits against a backdrop of no confirmed nationwide blackout at the moment, but Iran’s recent pattern argues against treating that as permanent. Cloudflare Radar is the settlement gauge, so any abrupt drop in total bytes transferred to 1.0% or less of the four-week peak would be the live signal to watch, especially if it coincides with a crackdown, wartime alert, or renewed protests.[14][1]

UK Frequently Asked Questions

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
