Prediction markets bet Anthropic will restore Fable 5 access after government shutdown

Anthropic Shuts Down Fable 5 Following Government Order

Anthropic disabled access to its Fable 5 and Mythos 5 models on June 12, just three days after launch, following a U.S. government order that sent shockwaves through the AI industry1

1

. The AI model disabled event came after Commerce Secretary Howard Lutnick directed the company to pull the model, marking one of the most aggressive regulatory interventions in AI development to date2

2

.

The government order barred every non-U.S. citizen from using Fable 5 anywhere in the world, creating an enforcement nightmare for Anthropic2

2

. With no practical way to verify citizenship, the company switched both models off globally, leaving even its own foreign-born engineers locked out and unable to work on fixes.

Amazon Researchers Trigger Security Crackdown

The shutdown stems from security findings by Amazon researchers who cracked the Anthropic AI model using a simple "fix this code" prompt to surface information useful for cyberattacks2

2

. Amazon CEO Andy Jassy escalated the findings to Treasury Secretary Scott Bessent and other federal officials, prompting swift action from the Department of Commerce. The irony is stark: Amazon has poured roughly $13 billion into Anthropic and holds a $100 billion cloud commitment from the company, yet its own security team triggered the crackdown that now threatens that investment.

This follows earlier friction between Anthropic and national security agencies. The Department of War had already blacklisted Anthropic as a supply chain risk in February after the company refused to let the military use Claude for autonomous weapons or mass domestic surveillance2

. The latest action represents a significant escalation in regulatory oversight of AI innovation.

Prediction Market Speculation Points to Quick Restoration

Despite the severity of the U.S. government order, prediction market traders remain optimistic about Fable 5 access returning soon. On Kalshi, traders place 58% odds that Anthropic will restore access to Fable 5 before July 1, with that probability climbing to 74% by July 101

1

. For these contracts to resolve positively, general access to the model must be restored to U.S. customers.

Polymarket shows slightly different odds, giving Fable 5 a 30% chance of returning to U.S. customers by June 19 and a 59% chance by June 262

2

. The company reportedly met with federal officials on Monday to discuss the issue, a signal that negotiations are underway1

Enterprise Firepower Now Sitting Dark

The timing couldn't be worse for Anthropic's enterprise ambitions. Launch partner Stripe reported that Fable 5 ran a codebase-wide migration across a 50-million-line Ruby codebase in a single day, work estimated to take an engineering team over two months2

2

. That enterprise firepower now sits idle while competitors like OpenAI continue operating unrestricted.

Anthropic argues the same vulnerabilities exist in rivals like OpenAI's GPT-5.5, which runs without restrictions while Fable 5 remains benched2

2

. This discrepancy raises questions about whether national security risks are being applied consistently across the industry or if Anthropic is being singled out due to its earlier refusal to cooperate with military applications.

The incident has already impacted market sentiment. The chance of Anthropic beating OpenAI to IPO has fallen from 83% to 62% since the shutdown2

2

. Meanwhile, investor Steve Eisman has turned cautious on hyperscalers like Alphabet, concerned that swelling AI spend now leans heavily on shareholders to fund it2
