Four academics carry California's Prop. 40 billionaire tax against a spending gap of more than 5-to-1

Four academics who drafted California's Prop. 40 are some of its loudest defenders against opponents who outspend them more than 5-to-1. Critics call the one-time billionaire tax a lab test. The vote will say whether California voters want to run it.

Newsom endorses Prop. 42, which would block California's billionaire tax if both measures pass and it gets more yes votes than Prop. 40

Gov. Gavin Newsom endorsed Prop. 42, which voids the Prop. 40 billionaire tax if both pass and Prop. 42 gets more yes votes. SFGATE reports polls consistently lean toward Prop. 42, so a Prop. 40 majority would not settle the question.

Prop 40's one-time billionaire tax faces doubts it will stay one-time, and its receipts would swing with the market

California's Prop 40 would levy a one-time 5% tax on the assets of residents worth over $1 billion, raising $100 billion by its union backer's estimate. Its lasting effect on a top-heavy, market-sensitive budget turns on repetition, the very spread opponents predict when they call it a Trojan horse.

Billionaire donors back a ballot measure that would nullify California's wealth tax

Opponents of California's one-time 5% billionaire tax have raised more than $300 million, about ten times what its backers have. For the few hundred people in scope, residency was fixed on Jan. 1, 2026, so payment and a rival nullifying measure are what remain open.

Super El Niño's Kelvin wave could lift California sea levels by up to 30 centimetres

Researchers warn an internal Kelvin wave from this year's super El Niño could lift California sea levels by up to 30 cm once it reaches the coast. The raised water would add to winter storm surges, though the oceanographer quoted expects it to distort tides for weeks.

Two phrases will decide what California's AI workplace laws cost employers

SB 947, signed by Governor Gavin Newsom on September 30, puts a human reviewer on firings and discipline decided primarily by AI from July 1, 2027. Its cost to employers depends on how 'primarily', and SB 951's 'in substantial part', end up being read.

Prop 40's union sponsor lines up Florida for 2028 whatever California voters decide

Dave Regan, the union leader behind California's Proposition 40 billionaire tax, says he would like a Florida vote in 2028 even if California says no. That makes wealth-tax and residency planning for the very rich a question about more than one state.

Property magnate David Reuben has moved to Monaco about 18 months after the UK put long-term residents' global assets under its 40% inheritance tax. In California, where Prop 40's residency date has passed, opponents of the 5% levy are outspending supporters almost six to one.

California's No Robo Bosses Act makes employers show workers the data behind AI-led firings

Gavin Newsom signed a law barring California employers from firing or disciplining workers on an AI system's judgment alone, effective July 1 next year. A human sign-off is cheap to add, and the costlier duty is the written notice explaining to each affected worker what data the system used.

California's billionaire tax must outpoll two rival amendments to survive

California voters will decide in November on Proposition 40, a one-time 5% tax on the net worth of the state's 250 billionaires, who hold $2.3 trillion. Whether any of them pays turns on a three-way vote count, since two rival amendments on the same ballot can undo it.

Sergey Brin's $102 million against Prop 40 equals 0.8% of the tax he could owe

Sergey Brin has given $102 million to defeat California's Prop 40, a one-time 5% billionaire tax that could cost him about $13 billion. The state's $100 billion estimate depends as much on how many of its 200 billionaires stay resident as on the November vote.
