The Trump administration's new AI export control order has sent immediate ripples through the industry. Anthropic, the AI safety company, took its newest models — Fable 5 and Mythos 5 — offline in response. Meanwhile, on the prediction market Polymarket, bets that UK Labour leader Keir Starmer will exit his role jumped to 84.5%.
Why the models were pulled
Anthropic's decision to remove Fable 5 and Mythos 5 from access came directly after the White House published the export control rule. The order restricts the transfer of advanced AI technology to certain countries. While the company hasn't elaborated on which provisions triggered the move, it's clear the models fell under the new restrictions. Anthropic declined to say whether the models would return in a modified form.
Polymarket bets spike on Starmer
The export order appears to have affected more than just tech companies. On Polymarket, a decentralized betting platform, the odds that Starmer would leave his position as Labour Party leader surged to 84.5% following the announcement. It's not immediately clear why the order — focused on AI hardware and software exports — would shift political betting. Market participants may be reading the order as a sign of broader instability or a shift in US-UK trade dynamics. Polymarket did not comment.
Questions over security and guardrails
Even before the export order, questions were mounting about Anthropic's models. Reports of guardrail bypass and security claims have drawn scrutiny. Critics point out that Fable 5 and Mythos 5 may have vulnerabilities that could be exploited if they fell into the wrong hands. The company has long positioned itself as a leader in responsible AI, but these reports challenge that narrative. Anthropic hasn't publicly addressed the bypass claims.
What happens next
The export control order takes effect in 30 days. Anthropic hasn't said whether it will seek a license to release Fable 5 and Mythos 5 internationally, or if it will retrain them to comply. Polymarket traders are watching for any further moves from the administration that could affect the bet on Starmer. For now, both the models and the political odds remain in limbo.
