Over a career of more than 60 years, he nearly doubled the average return of the S&P 500, delivering a total gain of 6,099,294% from 1964 to 2025.Missed Nvidia in 2009? This Rare Signal Is Flashing Again. In 2009, a "Double Down" signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same "Total Conviction" signal is flashing for a company 1/100th the size of Nvidia. Continue »Though Buffett is no longer the CEO of Berkshire Hathaway, having stepped down at the end of last year, he remains the chairman of the trillion-dollar conglomerate, and his wisdom remains just as valuable as it would if he were the CEO.While Buffett hasn't commented specifically on SpaceX, he did discuss the Uber IPO in an interview back in 2019 when the ridesharing company went public, and many of those comments could easily be applied to the SpaceX IPO.Image source: The Motley Fool.What Buffett thinks about IPOsIn an interview with CNBC's Becky Quick in 2019, Buffett said that Berkshire Hathaway hadn't bought an IPO in the 54 years that he'd been running the company, and that he sees them as a misalignment of incentives.He explained that the IPO process makes for a seller's market, saying skeptically, "To say that the best place in the world to put my money is where all the selling incentives are there... that that's going to be better than a thousand other things? That's the single best thing to buy in a single day?" He was suspect of the commissions and incentives used to push IPOs as well.Buffett and his longtime partner, Charlie Munger, also cast suspicion toward companies like Uber that had raised a lot of capital and spent, but were generating losses. The same could be said for SpaceX, which has raised and invested billions, but is still losing money following its merger with xAI.Buffett's simple litmus test for investingBuffett also offered a simple test for deciding whether to buy stock. He advised writing down, "I'm buying (x) stock because..." and if you can't give a good answer to that question, then you shouldn't be buying the stock.He explained that an answer like "my neighbor's buying the stock" isn't sufficient. The exercise is designed to be a check on irrational and impulsive decision-making, and requires the investor to make a strategic or fundamental argument for investing in the stock.Terms and Privacy PolicyEU DSA contactPrivacy & Cookie SettingsMore Info
