44 mental models every serious investor should know. What makes these useful isn’t how many you can memorize it’s how many you can actually apply when making decisions under uncertainty. A few worth keeping close: The McNamara Fallacy What gets measured gets managed but sometimes the most important variables can’t be easily quantified. Markets aren’t just numbers. Sentiment, incentives, governance quality, and strategy don’t fit neatly into a spreadsheet… but they drive outcomes. The danger is letting easy to measure metrics blind you to meaningful but hard to measure risks. The Semmelweis Reflex Markets hate new information especially information that challenges existing beliefs. Every cycle, investors dismiss certain trends as “temporary”… until they aren’t. Think EVs, cloud software, crypto, AI. Reflexive rejection is comfortable until it becomes expensive. The Baader Meinhof Phenomenon Once an idea enters your awareness, suddenly you see it everywhere. In markets, this can create false confidence and FOMO. Just because a theme dominates headlines doesn’t mean it’s investable or priced attractively. These frameworks don’t tell you what to buy they help you avoid being misled by your own psychology while you do it. Great investing is less about predicting the future and more about avoiding the mental traps that keep most people from seeing it clearly. #investing #finance

Many people think the only thing they need to afford when buying a car is the monthly payment, but the graphic shows that owning a car comes with many hidden expenses that can surprise you. These costs can add up quickly and take a bigger chunk of your budget than expected. Understanding the true cost of car ownership can help you make smarter financial decisions before signing that contract. The most overlooked expense is depreciation which starts the moment you drive the car off the lot and continues every year. Even cars that hold value well still lose thousands of dollars over time. This loss is a silent cost because you do not feel it until the moment you try to sell or trade in the car. Owning a car also comes with ongoing maintenance. Oil changes, tire replacements, brake pads, and fluids are normal parts of car ownership and these expenses can vary depending on the model you drive. Luxury cars or performance cars usually cost more to maintain because parts and service are more expensive. Insurance is another major cost that depends on age, location, driving record, and the value of your vehicle. Many buyers underestimate how much insurance increases when they switch from an older car to a newer one. Registration fees, inspections, and taxes also add yearly expenses that people forget to plan for. Gas prices can also shift your entire budget. When prices rise it affects daily driving, commuting, and family trips which can quickly add up depending on how much you drive. And if you enjoy modifications such as wheels, wrap, exhaust systems, or tuning, that becomes an extra financial layer that goes far beyond the original sticker price.

The FBI made a huge mistake. They took a hard drive with 3,400 Bitcoin on it (worth about $346 million) from a big drug case. When they tried to make a copy, they pressed the wrong button and wiped the whole drive clean. All the Bitcoin is gone forever. Even the experts couldn’t get it back. It’s one of the most expensive oops moments ever.

Fear has cost people more money than any crash ever could… The most expensive mistake you can make is waiting to start. 
Even if you had the worst timing imaginable (buying before every crash) you’d still be up today. And that doesn’t even include if you kept buying during the dips… 😬 
While most people panic, the wealthy see market selloffs as buying opportunities. They treat stock crashes like Amazon Prime Week. Because they know buying stocks at a discount helps them build their wealth faster.

The most expensive thing holding you back might be your conversations... It's hard to create a wealth building mindset when you're only surrounded by people who only talk about consumption and spending.

Newly leaked internal documents reviewed by TechCrunch reveal that Microsoft has already received $865.9 million from OpenAI through a 20% revenue-share deal covering the first three quarters of 2025. This payout is far lower than the multibillion-dollar revenue figures the company has often implied publicly. The documents also show that OpenAI’s inference costs reached an estimated $12.4 billion from early 2024 through Q3 2025, underscoring how expensive it is to run large AI models at scale. These costs are significantly higher than what many analysts previously assumed. The leak raises questions about the sustainability of OpenAI’s business model and whether its rapid growth is being fueled more by massive compute spending than actual profitability. It also highlights how dependent OpenAI remains on Microsoft’s infrastructure. If accurate, the numbers suggest that OpenAI’s financial reality is much more fragile than its public image. Investors and partners may now push for transparency around true revenue, margins, and long-term viability. Follow us (👉@artificialintelligenceee) for everything latest from the AI world.

One country controls more military aircraft than the next five air forces combined ✈️ In 2025, the United States fields about 13,000 military aircraft, while Russia has a little over 4,000 and China a bit above 3,300. Put together, the next five countries on the list still fall slightly short of the US fleet, which shows how concentrated real air power actually is. Dominating the air is expensive, but it’s one of the clearest advantages money and industrial capacity can buy. #AirPower #MilitaryMight #GlobalWealth #DefenseSpending #Wealth

Fired Higgsfield engineer just leaked “god-mode” promo code, allegedly unlocking 50% off most expensive plan and unlimited access to all models.

He claims it’s hard to patch without breaking other systems, and the leak is already ricocheting through forums and competitor chats. If true, this isn’t a discount - it’s a full-blown infrastructure and PR crisis. What are your thoughts on this? 🤔💬 #Sponsored
