Bitcoin surged over 10% to USD63,595 after an assassination attempt on Donald Trump, as traders bet on his increased chances of winning the US presidential election. Trump, seen as pro-crypto, has accepted cryptocurrency payments for his campaign and hosted industry executives, raising hopes for a regulatory shift. The incident also boosted shares in Trump's Truth Social media company and prison operators, while gun stocks saw volatility. The S&P 500 closed slightly higher, and US Treasury yields edged up, reflecting investor expectations of Trump's tax-cutting policies driving deficits and inflation.
