A judge in Nevada has granted the state’s gambling regulator a preliminary injunction against Polymarket. It is another victory for the state, which has been the most successful at fighting against prediction markets offering sports contracts. 

Polymarket was forced to restrict users in Nevada in February after Judge Jason D. Woodbury granted a temporary restraining order against the company. 

Judge Woodbury upheld that decision and granted the Nevada Gaming Control Board’s (NGCB) motion for a preliminary injunction against Polymarket. 

“We are very pleased with Judge Woodbury’s ruling and will continue to vigorously enforce Nevada law to safeguard gaming in our state,” stated NGCB Chairman Mike Dreitzer in a press release. 

Other Platforms Also Banned In Nevada

In addition to Polymarket, Nevada has successfully blocked Coinbase, Kalshi, and Crypto.com from offering sports event contracts in the state. 

The NGCB stressed that “the gaming industry is vitally important to the economy of the state and the general welfare of the inhabitants and therefore must be licensed, controlled, and assisted to protect the public health, safety, morals, good order, and general welfare of the inhabitants of the state.”

While Nevada is a huge market for casinos, it is a relatively small market for online gambling platforms. In order to wager online, Nevada residents must first register at a physical casino. 

Losing access to Nevada residents is not overly damaging to Polymarket, but the ruling will almost certainly be used against the company in other legal battles in other states. As a fully licensed platform in the US, Kalshi has generally been the target of state regulators, but since its relaunch in the country, Polymarket has also been facing legal challenges. 

The company is involved in ongoing litigation in Wisconsin, Michigan, Massachusetts, New York, and Rhode Island. But in all other states, users can access the platform, which offers a wide range of sports markets, including all major esports events. 

Casinos and Prediction Markets Continue To Do Battle

Prediction markets are seen as a threat to the casino industry, and major operators have refrained from entering the emerging market. 

Caesars and MGM, two of the leading casino companies in Vegas, offer online betting, but have said they have no intention of entering into prediction markets. 

Nevada warned licensed gambling companies that if they do business with prediction markets, then they risk losing their licenses. This led to DraftKings and FanDuel deciding to withdraw from the state. 

Lobbying on both sides has intensified recently, and Kalshi blamed casino-backed groups for an advertising campaign targeting the company. 

In response to the original ruling in Nevada in February, Polymarket said it would challenge the decision. A company spokesperson added: “We’re committed to seeing this through and to reopening access as soon as we’re allowed to do so.”

In addition to Nevada, Spain and Indonesia both blocked the platform last week. It is restricted in over 33 countries worldwide.

TL;DR

ChatGPT’s new Lockdown Mode disables live browsing, agent mode, and deep research to block data exfiltration via prompt injection. Available on all plans.

OpenAI has begun rolling out Lockdown Mode to ChatGPT, a new security setting designed to block attackers from stealing data through prompt injection attacks. The feature disables live web browsing, agent mode, deep research, image retrieval, Canvas networking, and file downloads. It is available to logged-in users across Free, Go, Plus, Pro, and self-serve ChatGPT Business plans.

Prompt injection remains what OpenAI calls a “frontier” problem affecting all large language models. The attack works by hiding malicious instructions in content the model processes, such as a webpage or uploaded file. If the model follows those instructions, it can be tricked into sending sensitive data to an attacker-controlled server.

Lockdown Mode does not stop injections from happening. A malicious payload embedded in a cached webpage or uploaded PDF can still influence the model’s behaviour. What it does is shut down the outbound pathways an attacker would use to exfiltrate the data. No live browsing means no network requests to external servers. No image retrieval means no pixel-based data channels.

“Lockdown Mode is designed to substantially reduce the risk of prompt injection-based data exfiltration, but it does not guarantee that data exfiltration cannot happen,” OpenAI said. “Risk may remain through enabled Apps, unforeseen combinations of capabilities, or newly discovered techniques.”

The trade-off is significant. With Lockdown Mode on, ChatGPT loses most of what makes its agent and research features useful. Live browsing drops to cached content only. Agent mode is gone entirely. Deep research is disabled. It is, as OpenAI acknowledges, “not intended for everyone.”

The feature arrives as prompt injection attacks on AI agents have become a growing concern. Security researchers have demonstrated hijacks against agents from Anthropic, Google, and Microsoft via their GitHub Actions integrations. All three paid bug bounties but published no public advisories. The underlying weakness is fundamental: LLMs cannot reliably separate data from instructions.

Lockdown Mode and Developer Mode cannot be used simultaneously. Turning one on disables the other. OpenAI also launched a separate session management feature that lets users review active ChatGPT sessions and log out of individual devices if they spot unauthorised activity.

The feature is a pragmatic concession. OpenAI is not claiming to have solved prompt injection. It is accepting that the problem persists and offering users a way to reduce their exposure by giving up functionality. For anyone handling sensitive data in ChatGPT, that trade-off is worth making. For everyone else, the expanding agent ecosystem and its growing attack surface mean the risk is only increasing.
