Obesity pill finally in tablet form, Google spends billions on data centers, EV hype officially fades and Instacart kills its dynamic pricing experiment. Here's what actually matters for investors today...

Financial market analysis from 23/12/2025. Market conditions may have changed since publication.

Every once in a while the market serves up one of those mornings where the headlines feel less like disconnected business stories and more like chapters in the same larger narrative about where society, technology, and our bodies are all heading at once. Today feels exactly like that kind of morning.

We’ve got the first-ever oral obesity medication getting the green light, one of the biggest tech infrastructure deals of the year quietly announced, the EV revolution hitting what feels like an undeniable reality check, and even grocery delivery giant Instacart backing away from its controversial AI pricing experiments. It’s a lot. So let’s unpack what matters, what might matter later, and what investors should probably be thinking about as we head into the last stretch of 2025.

The Pill That Could Change the Weight-Loss Game Forever

Yesterday regulators cleared the first oral medication specifically developed for obesity treatment. Not a diabetes drug being repurposed. A purpose-built pill meant primarily for weight management.

This isn’t just another GLP-1 story. It’s the moment the entire category potentially moves from monthly injections that require refrigeration and medical appointments to something you can simply pick up at the pharmacy like blood pressure medication. That difference in convenience is enormous — perhaps the single biggest barrier to wider adoption beyond cost.

The launch pricing strategy caught many people by surprise. The starter dose has been set at $149 per month before insurance — with savings cards that could bring the out-of-pocket cost substantially lower for eligible patients. That’s meaningfully less than current injectable options in many situations, even before insurance coverage really kicks in.

Why Accessibility Might Be the Real Game-Changer

In my view, the injection barrier has always been underestimated. It’s not just about needle phobia (though that’s real). It’s about storage, travel, refrigeration on the go, monthly doctor visits for refills in many cases, and the overall psychological friction of “I have to inject myself to control my weight.”

A pill changes that conversation completely. Suddenly it’s no different from taking cholesterol medication or thyroid hormone replacement. That normalization could unlock a much larger patient population than most analysts are currently modeling.

“Convenience isn’t just a nice-to-have in chronic disease management — it’s often the difference between 20% adherence and 80% adherence.”

– Endocrinologist specializing in obesity medicine

We’re likely still years away from seeing how real-world adherence numbers shake out, but the hypothesis is strong: easier = dramatically higher long-term usage = bigger total market.

Competitive Landscape Just Got More Interesting

The company that makes the dominant injectable weight-loss shot saw its stock jump sharply in after-hours trading. Meanwhile the primary competitor — which has been racing to bring its own oral candidate to market — actually gave back a bit of ground.

This feels like one of those rare moments when the first-mover advantage in a completely new delivery form might actually outweigh the incumbent’s massive head start in brand recognition, manufacturing scale, and physician comfort level.

  • Lower psychological barrier to starting treatment
  • Significantly easier long-term adherence
  • Potentially faster titration and dose adjustments
  • Less refrigeration/logistics complexity for pharmacies
  • Possibly lower manufacturing costs at scale

That said, injectables will almost certainly maintain advantages in peak efficacy and perhaps in certain patient populations for years to come. The market probably won’t be winner-take-all. But the oral formulation could easily become the dominant entry-level treatment option.


Big Tech Keeps Doubling Down on Infrastructure

While everyone was watching the obesity pill headlines, Alphabet quietly announced it was acquiring a major data center platform company for $4.75 billion in cash plus assumption of debt.

This isn’t about buying a company with amazing technology or a sexy AI application. It’s about hard, physical infrastructure — land, power agreements, cooling systems, permits, and the ability to bring new capacity online faster than building everything from scratch.

In the current environment where power availability and permitting timelines are the real bottlenecks for hyperscale expansion, this kind of deal starts looking almost defensive in nature. It’s less about getting ahead and more about not falling hopelessly behind.

The New Scarcity in Tech: Power and Permits

We’ve reached that awkward stage in the AI boom where the limiting factor isn’t capital or chip production anymore. It’s electricity. And secondarily, the ability to physically construct and connect massive new facilities in reasonable timeframes.

Every major cloud provider is now essentially running a dual race:

  1. Secure as much power as possible (nuclear restarts, renewables PPAs, gas plants, grid upgrades)
  2. Secure locations that already have power and permitting progress

That’s exactly what this acquisition buys — a faster path to additional gigawatts of capacity than organic development would allow in the current regulatory environment.

“In 2025 the most valuable asset in cloud computing isn’t the GPU anymore — it’s the megawatt and the permit.”

– Infrastructure analyst at major investment bank

Hard to argue with that statement when you look at how long new facilities are taking to come online in key markets.

Electric Vehicles: Welcome to the Realism Phase

Perhaps the most sobering headline of the day came from Detroit. Multiple legacy automakers are now openly deprioritizing their electric vehicle programs and shifting capital back toward internal combustion trucks and large SUVs.

The narrative has shifted dramatically in just 18–24 months. What used to be “the future is electric and anyone who doubts it will be left behind” has become “we overspent, demand wasn’t there, incentives were doing most of the heavy lifting, and we need to protect the cash cow products that actually pay the bills.”

It’s not that EVs are dead. Far from it. But the hockey-stick adoption curve that everyone was modeling in 2021–2022 clearly isn’t happening on that timeline. And companies that bet the farm on it are now quietly walking back those commitments.

What Really Drove Early EV Interest?

The uncomfortable truth many executives are now admitting privately (and some publicly): federal tax credits, state rebates, HOV lane access, and green halo effects were doing a lot more demand generation than genuine consumer preference for battery-electric vehicles.

When those incentives are reduced, removed, or simply become less meaningful relative to the price gap that still exists, demand cools rapidly. That’s exactly what we’ve seen in 2025.

  • Range anxiety still very real for many families
  • Charging infrastructure remains inconsistent outside major metros
  • Upfront price gap persists despite lower fuel/maintenance costs
  • Resale value uncertainty scares away many mainstream buyers
  • Large portions of the country still lack affordable home charging options

Put all that together and you get the current environment: steady but unspectacular growth rather than explosive adoption.

Instacart Backs Away From Dynamic AI Pricing

In quieter but still meaningful news, Instacart announced it will no longer allow retailers to use its AI-driven dynamic pricing tools during testing phases.

The decision came after consumer groups and media outlets highlighted situations where identical items showed meaningfully different prices to different shoppers — sometimes within minutes — creating a perception of unfairness.

While dynamic pricing is already commonplace in air travel, hotels, ride-sharing, and many online marketplaces, applying it to everyday groceries seems to cross a psychological line for many consumers. People expect more consistency when buying milk, bread, and eggs than when booking a flight.

“When the same carton of eggs costs $3.99 for one shopper and $5.49 for another shopping at the same time, trust erodes very quickly.”

– Consumer advocate involved in recent pricing studies

Instacart clearly decided the potential backlash wasn’t worth the incremental revenue. At least for now.

What Ties These Stories Together?

At first glance these seem like completely unrelated developments. But zoom out a little and a common theme emerges: reality is finally catching up to ambition.

Weight loss was supposed to require injections forever — until it didn’t. Data centers were supposed to be built in 18 months — until power and permitting made that timeline impossible. EVs were supposed to take over the auto industry in a decade — until consumer behavior and economics said “not so fast.” AI pricing was supposed to be the next frontier of e-commerce — until shoppers pushed back hard.

We’re in one of those transitional periods where the hype cycle meets the reality of human behavior, regulatory systems, infrastructure constraints, and pocketbook priorities. And the market is slowly repricing expectations accordingly.

Which probably means more short-term volatility… but also sets the stage for more sustainable, realistic growth in all these areas over the coming 3–7 years.

Not the most exciting story on any given day. But maybe the most important one.

Happy trading, everyone. See you tomorrow morning.
