Billions: The Show That Taught America How to Talk About Money

Somewhere in a glass tower on Sixth Avenue, a junior analyst is watching Billions on a second monitor while pretending to build a model. He’s not studying the plot. He’s studying the wardrobe. The watch. The way Axelrod holds a room by saying less than everyone in it. This is how the show actually worked. Not as entertainment. As curriculum.

Seven seasons. Forty-two Emmy submissions. Zero statues. And yet the Billions cast net worth conversation reveals something far more interesting than any award could: the staggering distance between what these actors played and what they actually took home.

Bobby Axelrod’s fictional portfolio cleared $9 billion at its peak. Damian Lewis, the Eton-educated Brit who played him, is worth roughly $25 million. That’s a 360x gap between character and performer. Furthermore, it’s the kind of math that would make even Wags reach for a stiffer drink.

From its 2016 premiere through its 2023 finale, Billions did something no other show managed. It made hedge fund mechanics feel like a spectator sport. Consequently, the series became required viewing in actual trading floors, Hamptons summer houses, and every business school library from Wharton to INSEAD. The show drew from real federal prosecutions of financial crime, loosely drawing from the government’s case against Steven A. Cohen of S.A.C. Capital Advisors.

Now the curtain’s down. Additionally, the proposed spinoffs set in London and Miami have reportedly stalled. What remains is the cast, their careers, and the question everyone in our world quietly asks: what did they actually make? Here’s the definitive breakdown of the Billions cast net worth in 2026.

Damian Lewis — The Winner Who Walked Away ($25 Million)

Bobby Axelrod didn’t just leave Axe Capital. He torched the building on his way out. Damian Lewis did something more elegant. In addition, he simply stopped showing up after Season 5, returned for the finale, and redirected his entire career.

The Billions cast net worth conversation starts with Lewis because his trajectory is the most Bobby Axelrod move any of them made. Born in St. John’s Wood, educated at Eton alongside actual future hedge fund managers, Lewis always understood the codes his character weaponized. Additionally, his father was a City insurance broker at Lloyd’s. Notably, the line between playing old money and being adjacent to it was never very thick.

Post-Billions, Lewis has been everywhere except where you’d expect. His debut album Mission Creep dropped in 2023 on Decca Records. A second album, Sweet Chaos, arrives June 2026. Meanwhile, he starred in the comedy Fackham Hall, now streaming on HBO Max, and has a World War II film Pressure hitting theaters in May 2026 alongside Andrew Scott and Brendan Fraser. He’s also filming The Runner, an action thriller with Gal Gadot for Amazon.

Lewis earned a Commander of the Order of the British Empire in 2022 and serves as an ambassador for the King’s Trust. At 55, he’s arguably more culturally relevant than at any point during his Billions run. Read the full Damian Lewis net worth origin story here.

Paul Giamatti — The Pivot That Outplayed Everyone ($25 Million)

If Damian Lewis made the Axelrod move, Paul Giamatti made the Chuck Rhoades play. Patient. Strategic. Willing to lose battles to win the war.

Giamatti stayed for all seven seasons of Billions, earning a reported $250,000 per episode. That’s roughly $2.5 million per season before taxes, agents, and managers take their cuts. By Hollywood standards, it’s respectable. By his character’s standards, it wouldn’t cover a month of legal fees.

The real pivot came after the show wrapped. Giamatti starred in Alexander Payne’s The Holdovers, which earned over $42 million at the box office and landed him an Academy Award nomination for Best Actor, plus a Golden Globe win. Additionally, his filmography now exceeds $6.5 billion in combined box office gross across more than 80 films.

What makes the Paul Giamatti net worth story genuinely interesting is its origins. His father, A. Bartlett Giamatti, was president of Yale University and the seventh Commissioner of Major League Baseball. Paul attended Choate Rosemary Hall, then Yale, then Yale School of Drama. Nevertheless, he was a member of Skull & Bones. The intellectual aristocracy that Chuck Rhoades wielded as a weapon wasn’t entirely fictional. Consequently, Giamatti understood institutional power because he grew up marinating in it.

He owns a condo in Brooklyn Heights and sold his Venice, California beach property for $2.4 million in 2023. Read the full Paul Giamatti net worth origin story here.

Maggie Siff — The Dark Horse Hiding in Plain Sight ($8 Million)

Before Maggie Siff played a performance coach at a fictional hedge fund, she temped at a real one. That biographical detail tells you everything about why her portrayal of Wendy Rhoades felt different from every other TV therapist. She’d actually sat in those chairs. She’d watched those people operate.

The Maggie Siff net worth figure sits at $8 million, which places her as the most undervalued asset in the entire Billions cast net worth portfolio. Her career arc includes three of the most critically revered cable dramas in television history: Mad Men, Sons of Anarchy, and Billions. Notably, two Critics’ Choice nominations for Sons of Anarchy and a Screen Actors Guild nomination with the Mad Men ensemble further validate her range.

Siff’s personal story carries weight that no screen role could manufacture. Her husband, Paul Ratliff, died of brain cancer in 2021. However, she continued working, continued raising their daughter Lucy, and in 2026 made her West End debut playing Joy Davidman in Shadowlands at the Aldwych Theatre in London. Furthermore, she serves as a spokesperson for Betterment, the digital financial advisory firm, which aligns perfectly with the financial fluency her Billions character projected.

Born in the Bronx. Bronx High School of Science. Bryn Mawr College. NYU Tisch. A Barrymore Award for Ibsen. However, this is a résumé that screams steady compounding, not flash-crash volatility. Read the full Maggie Siff net worth origin story here.

Corey Stoll — The Cautionary Tale of Replacing the Irreplaceable ($3 Million)

Corey Stoll walked into the most thankless job in prestige television. When Damian Lewis departed Billions after Season 5, Stoll’s character Michael Prince was promoted from recurring antagonist to series lead. Consequently, he played a tech billionaire with presidential ambitions. On paper, it was a career-defining opportunity. In practice, it was an inheritance nobody asked for.

The Corey Stoll net worth sits at an estimated $3 million. That figure becomes particularly stark when you consider his résumé. In addition, he played Congressman Peter Russo in House of Cards, earning a Golden Globe nomination. Marvel cast him as Yellowjacket in Ant-Man, the studio’s biggest box office machine. Woody Allen’s Midnight in Paris saw him embody Ernest Hemingway. Additionally, his filmography includes over 60 credits spanning nearly two decades.

Yet $3 million is what the market says he’s worth. It’s a cautionary tale about the difference between booking prestige roles and converting them into leverage. Stoll replaced a star, inherited a declining audience, and carried seasons that critics treated as an afterthought compared to the Axelrod era.

Michael Prince wanted to buy the presidency. Corey Stoll couldn’t buy the cultural moment. Read the full Corey Stoll net worth origin story here.

Asia Kate Dillon — The Ghost Who Changed Television ($2 Million)

In 2017, Asia Kate Dillon became the first openly non-binary actor to play a non-binary main character on American television. Their portrayal of Taylor Mason on Billions didn’t just earn a Critics’ Choice nomination. Ultimately, it forced the MTV Movie & TV Awards to merge their gendered acting categories entirely. Consequently, the cultural shockwave from that single casting decision is still reverberating through the industry.

The Asia Kate Dillon net worth sits at approximately $2 million. It’s the lowest figure in the core Billions cast net worth lineup. And it raises a question that the entertainment industry still hasn’t answered: what happens when your cultural impact massively outstrips your market value?

Dillon appeared in 47 episodes of Billions across five seasons. A supporting role in John Wick: Chapter 3 opposite Keanu Reeves followed. Voice work in Gen:Lock and The Simpsons broadened their range. In 2020, an EP called Handsomehands arrived, with proceeds donated to the Marsha P. Johnson Institute. Furthermore, they founded MIRROR/FIRE Productions, a company focused on race, gender, and identity in performance art.

Born in Ithaca, New York. Graduated from the American Musical and Dramatic Academy. Completed Meisner training at 16, the youngest student ever admitted. Taylor Mason’s supernatural calm under pressure wasn’t acting. Moreover, it was temperament. Read the full Asia Kate Dillon net worth origin story here.

David Costabile — The Wild Card Who Stole Every Scene ($6 Million)

Nobody watches Billions and thinks about David Costabile’s net worth. They think about Wags. Particularly, the cocaine. Those razor-sharp one-liners. A $500,000 casual donation that barely registered on his fictional balance sheet. Mike “Wags” Wagner became the character that hedge fund bros quoted in group chats and steakhouse dinners from Midtown to Montauk.

Costabile’s real-life story is the anti-Wags. Born in Washington, D.C. Tufts University. MFA from NYU. Married to Eliza Baldi. Furthermore, two daughters, Lucy and Julia. Lives in Park Slope, Brooklyn. He is, by every observable metric, a sensible person who happens to play degenerates with extraordinary precision.

The David Costabile net worth figure of $6 million reflects one of the most consistent careers in character acting. His credits read like a syllabus for peak television: The Wire. Breaking Bad. Better Call Saul. Damages. Flight of the Conchords. Notably, he appeared as James Ashley in Spielberg’s Lincoln. He played Doc McGhee in the Mötley Crüe biopic The Dirt. Most recently, he was cast in Percy Jackson Season 3 for Disney+.

In the Billions cast net worth rankings, Costabile occupies the sweet spot. Not rich enough to stop working. Too talented to stop getting hired. That’s the character actor’s paradise. And Wags would absolutely hate it. Read the full David Costabile net worth origin story here.

The Billions Effect on Hamptons Culture

No show did more to cement the Hamptons as a character in American television than Billions. Bobby Axelrod’s beach house. Additionally, the fundraisers. Every polo match. Those casually vicious conversations held over rosé at sunset while someone’s net worth evaporated in real time.

For our readers, the show wasn’t fiction. It was a slightly exaggerated documentary about people you’ve sat next to at Nick & Toni’s. Moreover, the Billions audience skews affluent, educated, and plugged into exactly the social dynamics that power the East End summer season. Consequently, the show’s cultural footprint maps almost perfectly onto the Social Life Magazine readership.

The Billions cast net worth breakdown reveals that playing ultra-wealthy characters doesn’t make you ultra-wealthy. However, it makes you recognizable to people who are. And in the Hamptons economy, recognition is its own form of capital. The real transaction was never between Showtime and its audience. It was between the show and the people it depicted — who watched themselves being watched, and liked what they saw enough to keep performing.
