Burnham lays out an ambitious vision at Labour conference, KKR flags AI concentration risk in credit markets, and OpenAI accuses Moonshot of a mass distillation attack.

Welcome to this week’s Market Pulse, your 5-minute update on key market news and events, with takeaways and insights from the Sidekick Investment Team.

Today, we’re looking at Andy Burnham’s ambitious conference speech, KKR’s warning about AI-linked debt, and OpenAI’s distillation accusations against Chinese rival Moonshot.

But first, our number of the week…

6%

That was the yield on 30-year UK gilts on Thursday, which hit 6% for the first time since 1998 amidst a global bond sell-off. Britain is now the first G7 economy to borrow at that rate in 14 years.

Sidekick Takeaway: Yields have spiked with investors fearing that oil prices above $100 will reignite inflation. With debt interest now the UK government’s second-largest line item, Labour’s October budget will be under more pressure than ever.

Only have a minute to read? Here’s the TL;DR:

• At the Labour Party Conference, Andy Burnham argued that Britain took a wrong turn in the 1980s, unveiling plans for greater public control of utilities and a new National Care Service. However, the speech offered few financing details beyond triple lock reform.
• KKR warned that AI-linked debt now makes up about 6.3% of the US investment-grade market. With tech firms planning nearly $8 trillion of infrastructure spending through 2030, roughly 20% of investment-grade bonds could become exposed to AI risks.
• OpenAI accused Chinese AI lab Moonshot of a ‘distillation’ campaign, querying its models at scale to replicate their capabilities. The claims follow similar accusations from Anthropic in February and have become a growing flashpoint in US-China relations.

Hope Again: Burnham Lays Out Ambitious Plans at Labour Conference

In a highly anticipated speech at the Labour Party Conference, Andy Burnham laid out a bold new vision for Britain.

Burnham used his speech to argue that Britain took a wrong turn in the 1980s, with free-market reforms undermining the public interest. Now, the PM wants to reverse course.

The speech unveiled several concrete policy proposals, including greater public control of utilities and a new National Care Service.

Yet Burnham largely sidestepped one of the most significant hurdles to implementing this new vision: Britain’s dismal finances.

New vision, old rules

Burnham did acknowledge the importance of being realistic about what the UK can afford. But the speech contained few details on financing Britain’s new direction:

• Burnham committed to reforming the costly triple lock system, which sees pensions rise by the highest of inflation, earnings, or 2.5%. Yet those changes won’t come until 2030.
• The speech also called for increased construction of public housing, which will be partly self-financing through reduced outlays on housing benefits.
• Beyond these topics, fiscal details were largely absent. Nonetheless, the PM did underscore his commitment to sticking to Labour’s budgetary rules.

To be fair, a keynote conference speech may not be the place for fiscal minutiae.

But without a concrete way to pay for it, great ambition can risk looking like cheap talk.

Sidekick Takeaway: John Healey’s conference speech contained slightly more fiscal details, although not by much. While the Chancellor emphasised the importance of ‘fiscal discipline,’ it remains to be seen how Labour plans to square that discipline with the party’s vision.

Extra Credit: KKR Flags AI Risks in Concentrated Debt Market

In a report published this week, one of the world’s largest alternative asset managers issued a stark warning on the rise of AI debt.

KKR, which manages nearly $800 billion, cautioned that the surge in technology-linked debt could disrupt credit markets in the event of an AI slowdown.

AI debt now amounts to about 6.3% of the US investment-grade market. Historically, the highest sector exposure has averaged just 2.9%.

If hyperscalers struggle to pay their debts, the ripple effects could extend well beyond the tech industry.

Too large, or not large enough?

In KKR’s view, the current investment cycle is ‘unusually concentrated’ in tech debt, creating unique market risks:

• A slowdown in the AI sector could see a sell-off in tech-linked bonds, potentially increasing yields – and impairing prices – across the credit market.
• With tech firms planning to spend nearly $8 trillion on infrastructure through 2030, KKR believes that roughly 20% of investment-grade bonds could end up exposed to AI risks.
• What’s more, given the rise of off-balance-sheet financing (such as data centre lease guarantees), the credit market’s true exposure could be even higher than it appears.

Still, AI bulls would argue that a technology poised to transform the global economy deserves such a large share of investor portfolios.

In fact, tech firms now make up nearly 40% of the S&P 500, far greater than the industry’s share of credit.

Sidekick Takeaway: Compared with equity investors, credit investors have different trade-offs when it comes to sector concentration. Bonds have limited upside, meaning that debt markets won’t capture the full gains of the AI bull case – but are still highly exposed to the bear case.

Copy Paste: OpenAI Accuses Moonshot of Mass Distillation Attack

OpenAI accused Chinese rival Moonshot of a systematic effort to extract data from the company’s models, a sign of growing industry angst over ‘distillation’ attacks.

Distillation involves querying a company’s models with a massive number of questions to extract its reasoning capabilities. Doing so can bypass the enormous cost of training a model directly.

According to OpenAI’s blog post on the topic, Moonshot’s efforts peaked at 16,000 requests over a multi-day period in late July.

Moonshot has historically denied using distillation to develop its models. Nonetheless, distillation claims are quickly becoming a geopolitical issue in their own right.

Private dispute, public response

OpenAI’s claims are just the latest in a string of distillation accusations against Chinese AI labs:

• In February, Anthropic published a blog post accusing Moonshot (along with other Chinese firms) of distillation attacks against the company’s Claude models.
• These accusations have become geopolitically significant. The Trump administration has accused Chinese firms of ‘malicious and targeted’ distillation, likely with government support.
• In fact, distillation was a key talking point at a recent summit between Xi Jinping and Donald Trump. China has called America’s accusations baseless.

Distillation attacks are a clear violation of OpenAI’s and Anthropic’s terms of service.

What’s less clear, however, is whether the companies can meaningfully do anything to prevent such attacks.

Sidekick Takeaway: The prospect of continued distillation attacks raises the question of how secure competitive moats are in the AI industry. If rivals can use millions of queries to copy a model shortly after release, the industry could soon be dominated by second-mover advantage, undermining the incentive for innovation.
