How much would Elon Musk’s SpaceX giveaway actually be worth? We put Sider Hand, our AI browser agent, on the case: researching across multiple sources, cross-checking figures, and doing the math. Here’s what it found. 👇
Next year, I will give one of my SpaceX shares to every kid in America. This will be the first of many.

Try this research prompt in Sider Hand → sider.ai/agents/hand Research Elon Musk’s X post: “Next year, I will give one of my SpaceX shares to every kid in America.”Work through the research in the browser and show your steps:Find the original post. Verify its wording and date, then look for follow-up details about how the shares would be distributed. Find the latest reliable estimate of the number of U.S. children under 18, preferably from the Census Bureau. Label this as an estimate for “every kid.” Find SpaceX’s latest available share price from a reliable source. Record the price and date. Estimate the total value of one share per child. Show the formula: number of children × price per share. Make clear that this is an estimate—not a confirmed total or completed gift. Create a clean, downloadable one-page visual report with the key figures, calculation, confirmed details, open questions, and clickable sources. Use primary sources where possible. Don’t fill gaps with assumptions. If you can’t verify the original post or a reliable share price, say so and continue with the best sources available.

DeepSeek V4.1 Flash is out. Does it actually save you money? We ran it inside the Sider Hand browser agent against two tiers models(Value and Frontier) on the same job: find a coupon, verify it on the real checkout page, apply it before payment. 12 real stores, every result checked by hand. The chart is net savings: coupons found minus the token cost of running the model. Astra found the most. V4.1 Flash kept the most — $385 net, at $0.11 per task. @deepseek_ai 1/6
